Transillumination negative for fluid. Extremities No edema, no cyanosis, brisk capillary refill Differentials? Management in the ED STAT Scrotal Ultrasound Urinalysis – normal Urine sent for culture – normal Urine GC/Chlamydia sent - negative Scrotal Ultrasound Scrotal Ultrasound Scrotal Ultrasound Scrotal Ultrasound Impression/Disposition Signed off as a case of Epididymitis + Small Varicocoele Pain relief + Prophylactic antibiotics Evaluation & Management of Children with Testicular Pain or Swelling Anatomy of the Testis Key Questions in the History Characteristic of the pain Recurrent pain suggests torsion History of trauma History of change in the size of the testicle Changes during Valsalva suggests communicating hydrocoele or varicocele Sexual history STD’s can cause epididymitis Difficulty voiding urine Suggests intraabdominal mass (hernia), UTI, neurologic problems or spinal cord disease Flank pain or Hematuria Suggests kidney stone with referred pain to the scrotum Abdominal pain with diminished appetite, nausea and vomiting Suggests testicular torsion Focused Exam Inspection Palpation Cremasteric Reflex Phren’s sign Blue dot sign Inspection Inspect while the patient is standing – check the penis, pubic hair and inguinal areas. Inspect for ulcers, papules, pubic hair infestations or lymphadenopathy Does the patient have any tattoo? Piercings? Inspection The left testicle is slighlty lower than the right Palpation Roll the testicle between thumb and forefingers to look for masses Palpate for the epididymis and go up towards the spermatic cord. Transilluminate the scrotum if swelling is suspected. Predicting Testicular Size Cremasteric Reflex Stroking the upper thigh results in elevation of the ipsilateral testicle. Usually present in boys 30 months to 12 years Less reliable in teenagers and infants Phren’s Sign Elevation of the scrotal contents relieves pain in patients with epididymitis and not with testicular torsion. POSITIVE SIGN – Relief of pain with elevation = EPIDIDYMITIS Not a reliable exam in most situations. Blue Dot Sign Almost always suggestive of torsion of the appendix testis. Additional Tests Test Purpose Complete Blood Count Elevated WBC count in torsion Test usually obtained for pre-operative purposes Urinalysis and Culture R/o UTI Pyuria may be seen in Epididymitis Gram stain, culture, rapid molecular amplification testing of urethral discharge -orNucleic amplification test of urine R/o sexually transmitted diseases Color Doppler Ultrasound of the Scrotum Check perfusion R/o torsion if cannot be excluded on clinical grounds Differential Diagnosis Testicular Torsion Trauma Torsion of Appendix Testis Incarcerated Inguinal Hernia Epididymitis/Orchitis Henoch-Schoenlein Purpura Referred Pain Non-specific Differential Diagnosis Hydrocoele Varicocoele Spermatocoele Testicular Cancer Torsion of the Testicle Inadequate fixation of the testis to the tunica vaginalis through the gubernaculum “Bell-clapper” deformity Twisting of the spermatic cord Venous compression and edema Ischemia Torsion of the Testicle Peak incidence in the neonatal period and the pubertal period ~65% occur during the 12-18 year old range due to increasing weight of the testicles Torsion of the Testicle Abrupt onset of severe testicular or scrotal pain <12 hours of duration 90% have associated nausea and vomiting Pain can be constant unless the testicle is torsing and detorsing Most boys report a previous episode in the past Torsion of the Testicle Diagnosis is made clinically. Impression is stronger if there are previous episodes Doppler ultrasound should be done if there are uncertainty in diagnosis False positive scans (diminished blood flow) Large hydrocoeles Abscess Hematoma Scrotal hernia False negative scans Spontaneous detorsion or Intermittent torsion-detorsion Torsion of the Testicles Timing of operation 4-6 hours (100%) >12 hours (20%) >24 hours (0%) The contralateral testis should also be explored; “bell-clapper deformity” is usually bilateral Surgical Detorsion + Orchiopexy Orchiectomy if non-viable Torsion of the Appendix Testis/Epididymis Pedunculated shapes of these structures predispose them to torsion Occurs most commonly in 7-12 year old boys Torsion of the Appendix Testis/Epididymis Pain is of sudden onset, similar to testicular torsion The testicle is non-tender, but there is a tender localized mass usually at the superior or inferior pole (+) Blue dot sign – gangrenous appendix Doppler ultrasound may be necessary to rule out testicular torsion – will show a lesion of low echogenicity. Blood flow to the affected area may be increased Radionuclide scan may show the “hot dog” sign of the torsed appendage. Torsion of the Appendix Testis/Epididymis Management Bed rest, Analgesia, Scrotal Support 5-10 days out patient Resolution No follow-up necessary Surgery Removal of the appendage; exploration of contralateral testis not necessary Epididymitis Inflammation of the epididymis Occur more frequently in late adolescent boys and even in younger males who deny sexual activity. Risk factors Sexual activity Heavy physical exertion Direct trauma Bacterial epididymitis – think of anatomical abnormalities Epididymitis (+) Sexual activity (-) Sexual Activity Chlamydia Mycoplasma N. gonorrhea E. coli Viruses Ureaplasma Mycobacterium CMV Cryptococcus (HIV) Enteroviruses Adenovirus Epididymitis Acute or subacute onset of testicular pain History of urinary frequency, dysuria, and fever Normal vertical lie on exam, scrotal erythema, (+) scrotal edema, inflammatory nodule Normal cremasteric reflex, with negative Prehn’s sign Epididymitis Doppler ultrasound may be necessary to rule out testicular torsion All patients should get a urinalysis and urine culture CDC guidelines in sexually active boys Gram-stained smear if urethral exudates or intrautheral swab specimen or Nucleic amplification test Urine culture of a first void urine RPR and HIV testing Epididymitis ADMSSION CRITERIA Doubt diagnosis (?Torsion) Severe pain Immunocompromised Unreliable patient Non-compliance CHILDREN SEXUALLY ACTIVE (+) Leukocytes in urine Empiric antibiotics – Bactrim*/Keflex* Ceftriaxone x 1 + Doxycycline x 10 days (-) Leukocytes in urine Supportive treatment [NON-BACTERIAL] Levofloxacin Ofloxacin • It is equally important to treat sexual partners if an STD is the likely cause. • Supportive therapy: Scrotal support, bed rest and NSAIDS Other Causes & Clues CAUSES CLUES & MANAGEMENT Trauma • Rarely – compression of the testis against the pubic bone from straddle injury Testicular rupture • Hematocoele Intratesticular hematoma • Color doppler may diagnose the abnormality Incarcerated Inguinal Hernia • Audible bowel sounds in the scrotum Henoch-Schonlein Purpura • Nonthrombocytopenic purpura, arthralgia, renal problems, abdominal pain, GI bleeding • Treatment is supportive bleeding in the GIT is more priority in management Orchitis • Usually viral (Mumps, Rubella, Coxsackie, Echovirus) • Brucellosis • Pain and tenderness of the testis with peculiar shininess of the scrotal surface • Symptomatic treatment rest and ice packs, NSAIDS Other Causes & Clues CAUSES CLUES & MANAGEMENT Referred Pain • Other signs and symptoms may be apparent • Examples include: • Urolithiasis • Nerve root impingement • Retrocecal appendicitis • Tumor Nonspecific Scrotal Pain • Mild scrotal pain in the light of a normal exam • Imaging is not necessary • Treatment is not necessary Scrotal Swelling Scrotal Swelling History & PE Hydrocele • (+) Transillumination • Increase in size during the day or with Valsalva • If non-communicating, no change in size. Varicocele • The spermatic cord has a “bag of worms” feeling secondary to vessel dilation • The varicoceles may be more palpable with standing or with Valsalva • (-) Transilluminate Spermatocele • Painless, fluid filled cyst on the head of the epididymis • (+) Transillumination localized to the head of the testis Testicular CA • Firm, painless mass that does not transilluminate • (+) Reactive hydrocele Brain Teaser An 18 year old male was seen in the ED for scrotal pain of 1 day. He denied previous episodes before. He recently recovered from a febrile “infection” about a week ago. Patient is sexually active with female partners. On exam, the testes were not enlarged, (+) tender to palpation B/L, Prehn’s sign was negative, no blue dot sign noted. Urinalysis showed leukocyte esterase and nitrites with pyuria. The ED attending asks you : “What’s the plan?” A. No additional test is needed – treat empirically with Ceftriaxone and Doxycycline B. Test for STD’s like Chlamydia and Gonorrhea C. Send the urine for culture and sensitivity D. Scrotal ultrasound to immediately rule out torsion. E. Admit the patient and annoy the floor team Brain Cruncher A 16 year old male was seen in the ED for acute onset of scrotal pain. On further questioning, he has had prior episodes of scrotal pain which lasted for only 2 minutes on the average. The astute ER attending got a urinalysis and scrotal ultrasound. The final diagnosis was testicular torsion. To alleviate the patient’s anxiety as to benefit of immediate surgery, what should the ED attending ask the patient at this point? A. “Where exactly is the pain?” B. “What is the quality of the pain?” C. “Was there any trauma to the groin?” D. “What time did the pain happen?” E. “Did you take any pain reliever and did it help with the pain somehow?” Thank you!
