Urinary Elimination Risk Factors for Problems of Elimination Conditions that result in Neurologic impairment (Neurogenic bladder) Trauma to the brain or spinal cord CVA Diabetic neuropathy (R/T metabolic derangements) Altered mobility Severe arthritis Cognitive impairment dementia Immunologic impairment or infection AIDS 2 Urinary System Urinary System Organs Renal Nephron Additional Kidney Functions Production of erythropoietin is essential to maintaining a normal red blood cell (RBC) volume. Erythropoietin stimulates bone marrow to produce RBCs and prolongs the life of mature RBCs. Production of renin. Renin starts a chain of events that cause water retention, thereby increasing blood volume. Kidneys affect calcium and phosphate regulation Renin-Angiotensin Mechanism Kidneys affect calcium and phosphate regulation Vitamin D The Kidneys produces a substance that converts vitamin D into its active form. Intestines absorb more Ca from foods. Disease Conditions Affecting Urination Prerenal, renal, postrenal classification Conditions of the lower urinary tract Diabetes mellitus and neuromuscular diseases such as multiple sclerosis Benign prostatic hyperplasia Cognitive impairments (e.g., Alzheimer’s) Diseases that slow or hinder physical activity Conditions that make it difficult to reach and use toilet facilities End-stage renal disease, uremic syndrome Pre-renal, renal, post-renal classification Decrease blood flow Condition of renal tissue Obstruction in the UT that prevents flow from kidneys Conditions of the Lower Urinary Tract Diabetes Mellitus and Neuromuscular Diseases Benign Prostatic Hyperplasia (BPH) Conditions Affecting Urination Conditions that make it difficult to reach and use toilet facilities Cognitive impairments Diseases that slow or hinder physical activity End Stage Renal Disease (ESRD) (CKD) Dialysis Renal Replacement Two methods Peritoneal Hemodialysis 14 Indications for Dialysis Renal failure that can no longer be controlled by conservative management (Conservative management would include dietary modifications and the administration of medications to correct electrolyte abnormalities.) Worsening of uremic syndrome associated with ESRD, which would include nausea, vomiting, neurological changes, and pericarditis) Severe electrolyte and/or fluid abnormalities that cannot be controlled by simpler measures (These abnormalities would include hyperkalemia and pulmonary edema.) by simpler measures Factors Influencing Urination Disease conditions Socioeconomic factors (need for privacy) Psychological factors (anxiety, stress, privacy) Fluid balance Nocturia, polyuria, oliguria, anuria Diuresis Fever Medications and medical procedures How would you help someone needing to void, but unable to initiate the process? Factors Influencing Urination Disease conditions Socioeconomic factors Need for privacy Cultural differences Psychological factors Anxiety Emotional Stress Privacy Factors Influencing Urination Fluid balance Nocturia, polyuria, oliguria, anuria Diuresis How would you help Fever someone needing to void, but unable to initiate the Foods process? Medications and medical procedures Fluid Balance Symptoms common to urinary disturbances include frequency urgency dysuria polyuria oliguria incontinence difficulty in starting the urinary stream. Medications and Medical Procedures Surgery (stress) Alterations in Urinary Elimination Urinary retention Urinary tract infection An accumulation of urine due to the inability of the bladder to empty Results from catheterization or procedure Urinary incontinence Urinary diversion Involuntary leakage of urine Diversion of urine to external source Urinary Tract Infection Signs and symptoms Pain or burning during urination (dysuria) Fever, chills, nausea, vomiting, and malaise Frequent and urgent sensation of need to void Blood-tinged urine (hematuria) Treatment Medication 22 Urinary incontinence Nursing Diagnoses Impaired Social Interaction r/t Loss of independence: clothing becomes wet with urine and odor. Impaired body image r/t incontinent of urine. Risk for impaired skin integrity. Impaired urinary elimination Self-care deficit: toileting 24 Physical Assessment Gather nursing history for the patient’s urination pattern and symptoms, and factors affecting urination. Conduct physical assessment of the patient’s body systems potentially affected by urinary change. Assess characteristics of urine. Assess the patient’s perception of urinary problems as it affects self-concept and sexuality. Gather relevant laboratory and diagnostic test data. Physical Assessment Skin and mucosal membranes Kidneys Assess hydration. Flank pain may occur with infection or inflammation. Bladder Urethral meatus Distended bladder rises above symphysis pubis. Observe for discharge, inflammation, and lesions. Urine Tests and Diagnostic Examinations Urinalysis Specific gravity Culture Noninvasive procedures Invasive procedures Urine Drainage Bag Catheterization Catheter insertion Closed drainage systems Catheter care Perineal hygiene Fluid intake Catheter irrigations and instillations Removal of indwelling catheter Alternative to urethral catheterization Types of Urinary Catheters Urinary Drainage System and Infectious Organisms Restorative Care Strengthening pelvic floor muscles Bladder retraining Habit training Self-catheterization Maintenance of skin integrity Promotion of comfort Indications for Catheterization Acceptable reasons for insertion of a Foley Catheter Obstruction to urine flow Surgical repair of bladder, urethra and surrounding structures Prevention of urethral obstruction from blood clots after genitourinary surgery Accurate I&O in critical patients Continuous or intermittent bladder irrigations Severe urinary retention Urinary incontinence with stage 3 – 4 pressure ulcers Comfort for terminal patient Bladder decompression for surgery 33 Foley Catheter Kit 34
