TUBERCULOSIS Tubercle bacilli may invade one or more (or even all) of the organs of the genitourinari tract and cause a chronic granulomatous infection that shows the same characteristics as tuberculosis in other organs. It develops during many years after the first clinical displays of tuberculosis. The urogenital tuberculosis exists mainly in age 20—40 years, rarely — at children and seniors. It occupies the first place among the unpulmonary forms of tuberculosis. TUBERCULOSIS OF BUDS AND THE URINARY WAYS Ethiology. The specific exciter — mycobacteria of tuberculosis (by the Koch stick) predetermines a process, which reaches the genitourinary organs by the hematogenous route from the lungs. The primary site is often not symptomatic or apparent. The kidney and possibly the prostate are the primary sites of tuberculous infection in the genitourinary tract. All other genitourinary organs become involved either by ascent (prostate to bladder) or descent (kidney to bladder, prostate to epididymis). The testis may become involved by direct extension from epididymal infection. Pathogeny. Basic by diffusion of tubercular infection there is hematogenical. At first kidney are struck, and from there the infection on the blood vessels gets in the kidney bowl, ureter, urinary bladder. Infection takes place in the period of primary or second generalisation tubercular process from the basic cell in lights, lymphatic nodes, bones, and muscles. Although the tubercular cells develop in both kidneys, the process makes progress in 70 % cases - only in one. Only after the unfavourable conditions to the clinical displays of tuberculosis of one kidney the defect symptoms join and second, which was until now considered healthy. That it is the principal reason of transformation of milliary tuberculosis of crust matter of bud in the destructive defeat of cerebral matter. Мicobacteria strike cortex and medulla matters of kidney. The tubercular cells, which are localized in the crust matter, heal over relatively quickly, and they are disposed in the cerebral matter, most frequent cavity disintegrates. Acute and chronic forms of tuberculosis of the urogenital system. Acute (milliary) form is displayed of general tubercular process and it hasn’t an independent clinical motion. An attention of urologists is concentrated on the chronic form of tuberculosis of the urogenital system. Pathomorphology. At a acute form of tuberculosis of kidney in the crust matter the typical lymphoidal or epitheliodal cellular humps, that have characteristic giant cages, similar to the Pirogov-Lanhgance cages arise up. At the chronic form of tuberculosis of buds humps are disposed at first in the crust and cerebral matter, mainly in area of kidney papillae and pyramids. Gradually they take shelter by ulcers, are added disintegration and form the cavities, which unite with the kidney bowl, by bowl or are isolated. Petrification of those cells or substitution of them by the fibrous fabric can take place in some cases, in other ones — form plural cavities, which often unite between it. Round cavities the inflammatory changes arise up and the humps appear, that testifies to combination of different stages of motion of tubercular process. These changes can be completed by full destruction of bud with development of pyonephrose. Gradually the tubercular process engulfs a fibre, and then Fatty capsule of kidney, that results in development of sclerosic or festering paranephritis. In case of diffusion of tubercular infection on the urinary bladder in the submucose basis the specific elements of productive inflammatory process appear. The process begins at first near the opening of ureter. The tubercular humps appear on the mucus shell. In the case of their confluence between itself and necrotisation the ulcers and then scars appear at that place. 2 The defeat of all layers of wall of urinary bladder and substitution of her by the sclerozed fabric can result in the wrinkling a urinary bladder (microcystis). Immunity Immunity in tuberculosis is the result of a complex series of reactions which are not yet completely understood and which do not give the same high degree of protection which follows, say, diphtheria immunization. In a primary infection the bacilli are ingested by macrophages, processed to produce antigens which are presented to specific receptors on T-lymphocytes in association with HLA DR (human leucocyte antigen D related) glycoprotein on the macrophage surface. The need for the correct HL antigen may explain why individuals appear to vary in their resistance to tuberculosis. The presentation of the antigen to the helper T-cell also requires the production of interleukin 1 by the macrophage. The activated Tcell produces interleukin 2 and a number of lymphokines, which mediated the following reactions: 1. Stimulation of B-cells to produce antibody; 2. Induce delayed type hypersensitivity; 3. Activate cytotoxic cells; 4. Cause inhibition of macrophage motility. An excess of mycobacterium antigens may stimulate suppressor T-cells. At the primary infection macrophages ingest the tubercle bacillus, but they are unable to kill the bacilli which may multiply within it. The cells retain their motility and, at this stage can, carry the bacilli to other parts of the body. When delayed hypersensitivity develops 3-6 weeks after infection, the macrophages acquire the ability to kill the tubercle bacillus, although this is not entirely successful. They and helper T-cells now accumulate around focus of infection. The lymphokines inhibit the motility of the macrophages and induce them to become epitheloid cells or Langhans giant cells. The typical tuberce now forms with epitheloid cells surrounded by lymphocytes and fibrous tissue at the periphery. The tubercle may heal at this stage or at any further stage or it can enlarge and perhaps undergo central necrosis of a special type called caseous necrosis. This caseum can 3 liquefy and discharge into a renal tubule, lymphatic or blood vessel liberating large numbers of tubercle bacilli which spread the infection locally or to other organs. Healing is associated with much fibrosis and calcium salts are laid down in this caseum. It is only after delayed hypersensitivity develops that tissue damage occurs. Neither the tubercle bacillus, extracts of neither it nor culture filtrates can be shown to possess toxic properties for the uninfected animal or human being. Hypersensitivity is demonstrated by the intradermal injection of Old Tuberculin or Purified Protein Derivative (Mantoux Test). This test may be of use in diagnosis if it is known that the patient has previously been skin test negative and has not had BCG vaccination. There is an association between a moderate degree of hypersensitivity and resistance to tuberculosis, but a high degree has usually disadvantageous. Some protection can be given to a healthy animal by the injection of lymphocytes from a tuberculous animal but the transfer of serum gives no protection. Tuberculous antibodies can be assayed in the serum of tuberculous patients by a variety of methods but their significance is unclear. Corticosteroids cause a lymphopenia and thus abolish delayed hypersensitivity. For this reason the administration of corticosteroids and cytotoxic drugs is sometimes associated with the reactivation of tuberculosis. Infections with M. Tuberculosis, M. bovis or atypical mycobacteria are common in patients suffering from AIDS in which helper T-cells are reduced. Classification. In practice they make a use of the сlinical-roentgenologic classification of tuberculosis of buds offered by М. О. Lopatkin with coll. (1977): I stage — nondestructive (infiltrate) tuberculosis of kidney; II — initial destruction (papillitis or small, by diameter about 1 cm, single cavity); III —marked destruction (caverns or policavernosial tuberculosis one of kidney segments); 4 IV — total or subtotal destruction (policavernose tuberculosis of two segments, tubercular pyonephrose, calcification kidney). The one criterion (degree of destruction of kidney fabric) is fixed on basis of this classification. They distinguish three forms of tuberculosis: tuberculoinfiltrative, ulcerous and scar. Clinical picture. For kidney urinary tract T.B main features are. On the early stages of disease, when in parenchyma the first tubercular humps appear, sometimes-general weakness, indisposition, rapid fatigue, reduction of body weight, lose of appetite, dull pain in the lumbar region, subfebril temperature of body exists. In the case of the process sharpening, penetration of tubercular cell in the kidney bowl the chill can appear. The temperature curve gains a gectic character, sharp or dull pain appears in the lumbar region, and disurical discords exist. The kidney pain exists at the corking by ureter rawsimilar (caseosic) the masses. On the late stages of process, especially in case of bilateral defeat, all signs of chronic insufficiency of kidney appear. For tuberculosis of kidneys of change in blood also are unspecific. Frequently they mark a moderate lecocytosis with shift to left and by the insignificant reduction of quantity of granulocyte leukocytes. Leukopenia and hypohromic anaemia can exist. The ESR (erythrocyte sedimentation rate) changes answer a process activity. If changes of blood are not specific for tuberculosis of urinary systems, the appearance of pyuria, microhaematuria, proteinuria is signfull for a doctor. In a sick on the bud tuberculosis the urine reaction is acid. For the exposure in its sediment of pathological elements they apply a provocative test — hypodermic enter 15—20 tuberculin. The leukocyte- and erithrocyturia increases at tuberculosis. The tuberculosis of ureters results in the increase of retention of urine in kidney, worsening the same a motion of tubercular process. The specific narrowing of ureters causes the development of ureterohydronefrosis, pyonephrosis. The attacks 5 of kidney pain exist at ureters obturation. As far as death of kidney parenchyma the pain diminishes, and the kidney becomes “mute”. The objective displays of tuberculosis of urinary bladder at first are wretched. There is a frequent, painfully, imperative urination that is accompanied with the terminal hematuria which is impossible to consider an early sign. The same is up to the changes of mucous membrane, which expose during the cystoscopy. Diagnosis. The most reliable and objective sign of tuberculosis of urinary organs is an exposure in sediment of urine the mycobacteria tuberculosis. For this purpose they apply bacterioscopical, bacteriological, biological methods of research, a frequent sowing of urine and other. For the exposure of morphological and functional changes in kidney they use the roentgenologic methods of research. In the initial stages of disease the pathological changes on excretory urograms can’t be find if there are the same violations, how at unspecific pyelonefritis or necrotic papillitis — eaten uneven contours in area of small bowls. As far as progress of process on excretory urograms expose single or plural cavities, which have uneven edges. At the productive stage of kidney tuberculosis on urograms it is possible to expose a defect of the filling, compression or amputation of bowl. The expansions often exist and even obliteration kidney bowl. In the case of diffusion of tubercular process on ureter pulls, even narrowing and expansion of it without the visible peristaltic waves are marked. After wards the plural narrowing of ureters appears. If the excretorial urography through the considerable decline of kidney function doesn’t give a clear image, the retrograde pyelography is recommended. In case of a sharp decline of kidney function the conducting of antegrade pyelography is expedient. On the high-quality pictures it’s successfully to expose the same changes, as well as at the ascending pyelography. The kidney angiography is applied rarely, so far as in the early stages of disease on angiogramms it is impossible to expose the specific characteristics concerning 6 the tuberculosis changes. Its value grows in that case, when a resection of kidney is planned. From data of arteriogramms they determine location of cavity and arterial kidney vessels. The cystoscopy is the most informative method of diagnostics of tuberculosis of urinary bladder. In the early stages of tuberculosis of urinary bladder the mucous membrane can be normal. On background pink mucous membrane expose small areas of hyperemia and hemorrhages. Near the opening of the ureters staggered kidney it is possible to expose a shallow primrose or grey-yellow tubercular humps with the reddish rim on periphery. The opening ureterus is pulled in, deformed; it has the shape of crater. Thus a function of its locking vehicle, that results in the origin of bladder-ureteral reflux is violated. To the extent of process progress the humps can be, the surface of mucous membrane above them takes shelter by ulcers. The characteristic changes of the opening of the ureterus staggered kidney exist – swollen mucous membrane. It is possible to expose the considerable changes by cystography. The diminished, deformed urinary bladder is exposed considerably at the neglected processes on cystograms. Its contours are eaten. They often establish bladderureteral reflux in bud, that is staggered less. The ureter tuberculosis exists very rarely. Diagnose is based on data of bacteriological research of urine, excretions from urinary tract. The narrowing of ureter exposes on ureterograms. Tubercular defeat of urinary bladder, that is accompanied by the swelling up of mucous membrane, after motion reminds a tumor of urinary bladder, and tubercular ulcer — simple ulcer of urinary bladder (intersticial cystitis). In case of diagnosis in such case establishment takes into consideration the results of bacteriological research, and in the case of doubt they recommend an endovesical biopsy. 7 Differential Chronic nonspecific cystitis or pyelonephritis may mimic tuberculosis perfectly, especially since 15-20% of cases of tuberculosis are secondarily invaded by pyogenic organisms. If nonspecific infections do not respond to adequate therapy, a search for tubercle bacilli should be made. Painless epididymitis points to tuberculosis. Cystoscopic demonstration of tuberculosis and ulceration of the bladder wall means tuberculosis. Urograms are usually definitive. Acute or chronic nonspecific epididymitis may be confused with tuberculosis, since the onset of tuberculosis is occasionally quite painfull. It is rare to have palpatory changes in the seminal vesicles with nonspecific epididymitis, but these are almost routine findings in tuberculosis of the epididymis. The presence of tubercle bacilli on a culture of the urine is diagnostic. On occacion, only the pathologist can make the diagnosis by microscopic study of the surgically removed epididymis. Amicrobic cystitis usually has an acute onset and is often proceeded by a urethral discharge. “Sterile” pyuria is found, but tubercle bacilli are absent. Cystoscopy may reveal ulcerations, but there are acute and superfical. Although urograms show mild hydroureter and even hydronephrosis, there is no ulceration of the calices as seen in renal tuberculosis. Interstitial cystitis is typically characterized by frequency, nocturia, and suprapubic pain with vesical filling. The urine is usually free of pus. Tubercl bacilli are absent. Multiple small renal stones or nephrocalcinosis seen by x-ray. May suggest the type of calcification seen in the tuberculous kidney. In renal tuberculosis, the calcium is in the parenchyma, although secondary stones are occasionally seen. Necrotizing papilitis, which may involve all of the calices of one or both kidneys or, rarely, a solitary calyx, shows caliceal lesions (including 8 calcifications) that simulate those of tuberculosis. Careful bacteriologic studies will fail to demonstrate tubercle bacilli. Medullary sponge kidneys may show small calcifications just distal to the calices. The calices, however, are sharp, and no other stigmas of tuberculosis can be demonstrated. Urinary bilharziasis is a grate mimic of tuberculosis. Both present with symptoms of cystitis and often hematuria. Vesical contraction, seen in both diseases, may lead to extreme frequency. Schistosomiasis must be suspected in endemic areas; the typical ova are found in the urine; cystoscopic and urographic findings are definitive in differential diagnosis. Complication A. Renal Tuberculosis. Perinephric abscess may cause an enlarging mass in the flank. A plain film of the abdomen will show obliteration of the renal and psoas shadows. Sonograms and CT scans may be more helpful . Renal stones may develop if secondery nonspecific infection is present . Uremia is the end stage if both kidneys are involved . B. Ureteral Tuberculosis : Scarring with strcture formation is one of the typical lesions of tuberculosis and most commonly affects the juxtavesical portion of the ureter . This may cause progressive hydronephrosis . Complete ureteral obstruction may cause complete non-function of the kidney. C. Vesical Tuberculosis: When severely damaged , the bladder wall becomes fibrosed and contracted. Stenosis of the ureteres or reflux occurs, causing hydronephrotic atrophy. D. Genital Tuberculosis: The ducts of the involved epididymis become occluded. If this is bilateral, sterility results. Abscess of the epididymis may rupture into the testis, through the scrotal wall, or both, in which case the spermatogenic tubules may slough out. Treatment The main principles in the treatment of tuberculosis are that: 9 1. No antituberculous drug is to be given alone; 2. Treatment should be continued for 4 months or longer if necessary; 3. The doctor should be able to convince the patient of the necessary to take the prescribe drugs regularly. The standard drugs for the treatment of tuberculosis are now isoniazide, rifampicin, pyrazinamide and ethambutol given in daily doses (Table). Treatment is started with the first three drugs and maintained until the sensitivity results are known. In light of this information, treatment is continued with two drugs to which the organism is sensitive, isoniazid and rifampicin will be prefered. If the organism is resistant to two or more of the standard drugs then streptomycin and ethambutol may replace them. Multiple resistance is now rare in the developed world and it should not be necessary to fall back on any of the other drugs formerly in use. This system is well tried and can be expected to give excellent results in the majority of cases. The course of treatment should last 4 months or longer according to the severity of the disease. Gow and Barbosa (1984) consisting of 2 months` daily treatment with rifampicin, isoniazid and pyrazinamide followed by isoniazide and rifampicin three times a week for 2 months recommend a short course of treatment. The American Thoracic Society (1980) have reviewed the results of trials of short-course and intermittent treatment of pulmonary tuberculosis and recommended a minimum duration of 9 months` treatment with isoniazid and rifampicin for uncomplicated pulmonary tuberculosis. However, they excluded nonpulmonary tuberculosis from short-course treatment. 10 Table DOSAGE TABLE FOR STANDARD TREATMENT Streptomycin Isoniazide 1 g daily 200-300 mg daily i. m. oral Rifampicin 600 mg daily oral Ethambutol 25 mg/kg daily for 2 months oral 15 mg/kg daily thereafter Pyrazinamide 1,5-2 g daily oral The British Thoracic Association (1980) reported a 7% relapse rate after 6 months` treatment of pulmonary tuberculosis with daily isoniazid and rifampicin plus an initial supplement of ethambutol or streptomycin for 2 months. The followup lasted from 3 to 4 years. The current use of three bactericidal drugs may explain the success of the short course given by Gow and Barbosa. At the same time it should be noted that surgery still plays an important part in their regime. If the urologist has little experience in the chemotherapy of tuberculosis the advice of a chest physician should be sought. If tuberculosis is treated with a single drug, the organism quickly develops resistance to it. For example, after 3 months` treatment with isoniazid alone, resistance to it was found in 62 % of the patients still producing a positive culture. If the organism is resistant to one of a pair of drugs used in treatment, resistance will develop to the second drug as if it were being given alone. The reason for starting treatment with three drugs is the possibility of primary resistance. In Scotland in 1985 the incidence of primary resistance to isoniazid and pyrazinamide single or together was 7 % of newly diagnosed cases. One patient was resistant to ethambutol and one was multiresistant. Isoniazid is a highly effective bactericidal drug, which can promote the healing of recent lesions by resolution without fibrosis. In standard doses it is almost nontoxic. Rifampicin is also bactericidal and very active. In normal daily dosage 11 toxicity is low, but if pretreatment liver function tests are abnormal it should not be used. During treatment with rifampicin the liver function tests may become abnormal, but if there is no clinical evidence of liver damage, treatment can be continued as the test usually reverts to normal. When rifampicin is used in intermittent treatment the dose may be raised to 1200 mg twice weekly. In this situation toxic reactions are more frequent and may be serious enough to stop treatment. The principal side effects with this dosage are the `flu` syndrome and thrombocytopenia often associated with the development of antibodies to rifampicin. The major toxic effect of ethambutol is retrobulbar neuritis whose early signs are blurred vision and defective color vision. This can be minimized by not exceeding a daily dose of 25 mg/kg for the first 8 weeks and then reducing to 15 mg/kg. Tests of visual function should precede treatment, which should be stopped immediately the patient complains of any visual disturbance and a full ophthalmological examination is carried out. In view of the difficulty of testing visual activity in young children, ethambutol should not be prescribed for them. Impaired renal function is a contraindication at any age. A full recovery from visual toxicity can be expected if the ethambutol is stopped immediately. In the past, pyrazinamide has been regarded as too hepatotoxic for routine use, but now a single daily dose of 1-5 g before breakfast has been found to be effective and free from side effects. It is a bactericidal drug effective at the acid pH to be found inside cells. M. bovis is naturally resistant to pyrazinamide. Rifampicin may stimulate the drug metabolizing enzyme system of the liver. As a result of this the serum concentrations of the following drugs may be reduced when given along with rifampicin – cardiac glycosides, oral contraceptives, anticoagulants, oral antidiabetics, corticosteroids and narcotics and analgesics. Women treated with rifampicin and wishing to avoid pregnancy should use a method other than an oral contraceptive. Sensitization rashes occur with all the antituberculous drugs. Once the offending drug has been identified it is simpler nowadays to switch to an alternative drug. If this is not possible, the patient may be desensitized by giving a 12 small dose and gradually increasing it. Alternatively, treatment can be continued with normal dosage under cover of corticosteroids, but it is absolutely essential that the organism be known to be sensitive to the drugs in use if disastrous consequences are to be avoided. If ureteral obstruction is discovered at the time of diagnosis or later, oral Prednisolone 20 mg daily should be started. This must be monitored weekly in case of surgical intervention is required. In the average case of renal tuberculosis sufficient healthy nephrones are present to maintain renal function within normal limits, but if there is over 50, renal function may be poor because of disease other than tuberculosis, so it is advisable to have renal function tests performed on these patients before starting treatment and if they are found abnormal then the drug levels should be monitored. If streptomycin has to be given to an elderly patient, the dose should not exceed 075 g per day so as to avoid ototoxicity. In-patient treatment is no longer necessary, but whether a short course as given by Gow and Barbosa (1984) or daily dosage for 9-12 months is used, close supervision is necessary because the need for surgical intervention can appear rapidly. Follow-up for an uncomplicated case need no longer than 1 year, but should be for several years if calcification is present. A medical treatment of patient with tuberculosis of the urinary system is based on the general principles of antituberculouse therapy and includes the measures of both conservative and surgical nature. The volume of medical treatment relies on stage of pathological process. A conservative medical treatment is to be complex: specific chemotherapy, good feeding, climate- that vitaminetherapy, resort, medical treatment. They usually apply simultaneously three specific antituberculouse drugs of different mechanism of action. To drugs of I line-belongs streptomycin, sodium of paraaminosalicylatis, isoniazid (tubasin) and its derivatives (phtivasid, metasid, salusid, larusan, inga-17І). To drugs II line-belong aetionamid, cycloserine, tyoacetason, aetoxid, pirasinamid, and florimycin sulfate. 13 The primary course of continuous medical treatment by the antituberculous preparations proceeds not less than year. Out that it is carried under surveillance of urologist-phtisiatrist. The antirecidive courses by duration the 1,5— 2 months are conducted during the 3—4 years in the spring-autumn periods. For the medical treatment they use one of the derivatives tubasidum in combination with aetoxidum or to sodium of paraaminosalicylatis. In children with limited destruction of kidney (III stage) during the 10 months they conduct therapy by drugs I line, where upon they appoints drugs II line. On the whole antibacterial medical treatment at this pathology there are to proceed 2 years. They conduct the antirecidive therapy by courses for the 2—3 months during the 3 years. They use the combinations of sodium of paraaminosalicylatis, tubasidum and preparations II line. Application of rifampicin, ethambutol considerably promotes the efficiency of therapy of a sick on tuberculosis. In case of united defeat of kidney by the tubercular process and pyelonephritis they conduct the medical treatment taking into consideration the second microflora of urine, its sensitiveness to the antibiotics. In period of medical treatment it is necessary to appoint group vitamins, enzymes and biogenic drugs (lidase, aloe, vitreous body). In the case of tubercular defeat of urinary bladder the antituberculosic drugs are appointed together with instillation cods-liver oil, solutions of tybonum, to sodium of paraaminosalicylatis. The medical treatment proceeds 12-18 months. The duration of the conservative medical treatment concerning tuberculosis of kidney and urinary tract depends on the disease stage, but in any case it is to be protracted and continuous. The patients are under the supervision in the antituberculosic clinic. For the control after efficiency of the medical treatments they conduct regularly the ambulatory and hospital inspection (analyses of urine and blood, bacteriological research of urine with determination of sensitiveness of micobacterias tuberculosis to drugs), if it’s necessary they conduct the roentgenologic and radionuclide research of the urinary organs. 14 The organsafe operations execute at the limited destructive tuberculosis (cavity of largenesses or policavernose process in one of kidney segments) of one or both kidney with normal their total function, and also at the destructive tuberculosis of one bud in combination with tuberculosis of ureterus and at tuberculosis of urinary tract (in the case of a necessity renewal urine arcade). If the destructive tuberculosis of kidney has a limited nature, shown cavernotomy, cavernectomy, and resection of kidney. Cavernectomy and cavernotomy aren’t now practically applied. In case of the single narrowing of ureterus on the small distance they execute the resection of this area and they impose anastomosis after type end to end, at strictures of pyeloureteral segment — resection with imposition of anastomosis after the Anderson-Haync method or Coachman. In the case of strictures pelvic part of ureters necessary direct or indirect ureterocystoneostomy. At plural strictures ureters they execute an operation of substitution by its a thin bowel on mesenterium, that is the intestinal plastic of ureterus. After operation a patient have to get antituberculosic drugs for a year. In the case of the wrinkling of the urinary bladder (microcystis) they execute the intestinal plastic. Thanks to this interference a capacity of urinary bladder is multiplied and the urine outflow gets better from the upper urinary tract. An additional reservoir is usually created from the ileum (ileocystoplastic) bowel or sygmocystoplastic. In the postoperative period-protracted (close 3— 6 months) specific chemotherapy in the conditions of permanent establishment is necessary. About the full convalescence they testify absence of changes with the complement of urine during 5 years after the completion of medical treatment and positive dynamics of immunological and roentgenoradiological indexes. Prognosis The prognosis depends upon severity & prolongation of the disease and the organs involved, but the overall control rate is 98 % at 5 years. The urine must be investigated bacteriologically every 6 months during treatment and then every year 15 for 10 years (Wechsler and Lattimer, 1975). Relapse will indicate the need for reinstitution of treatment. Nephrectomy is rarely necessary. In the healing process, ureteral stenosis or vesical contraction may develop. Appropriate surgical intervention may be necessary. References: 1. Donald R. Smith, M.D. General Urology, 11-th edition, 1984. 2. O.F.Vozianov, O.V.Lyulko. Urology.- Kyiv: Vischa shkola, 1993. 3.
