Genital-urinary System Renal System Part 2 Behavioral Objectives • Identify and describe the etiology, pathophysiology, clinical manifestations, nursing management and patient education for the following: – – – – • • • Urinary retention Urinary incontinence Urinary suppression Residual urine Discuss common pharmacological interventions appropriate in treatment of patient with GU disorders Describe general nursing consideration and intervention in pre and post-operative care of patients undergoing urological surgery Describe etiology, pathophysiology, clinical manifestations, nursing management and patient education for the following GU disorders: – – – – – – – – Pyelonephritis Cystitis Urinary tract infections (UTI) Urethritis Nephritic syndrome Hydronephrosis Renal calculi Renal neoplasm’s Dysfunctional Voiding Patterns • Urinal Incontinence • Pathophysiology – – – Unplanned loss of urine that is sufficient to be considered a problem Continence requires intact urinary, neurologic and muscularskeletal systems Any break in communication between these systems can lean to incontinence (or residual) Types of Incontinence • Stress Incontinence – – – Involuntary loss of urine through an intact urethra due to a sudden h in intra-abd. pressure Treatment-mild: Biofeedback & bladder drills Treatment-moderate to severe: surgery • Pelvic Floor Training and the role of Biofeedback: Health Care Professionals usually advise Pelvic Floor Training as a first line treatment or an adjunct therapy for urine leakage that occurs during coughing, laughing or on exertion. Pelvic floor exercises are effective, but only if carried out regularly and diligently. The lack of feedback on progress may lead to frustration and the discontinuation of an exercise routine, hence, it is prudent to choose devices/exercisers with biofeedback function, such as Peritron Perineometer and PFX range of pelvic floor exercisers with pressure biofeedback. The challenge is to motivate and encourage the workout and simultaneously ensure exercising of the correct muscles. Appropriate feedback will stimulate discipline and step-wise progress. PFX is available in 2 versions - vaginal for women only and anal that can used by both men and women. PFX and Peritron Perineometer products can help people, who wish to monitor the effectiveness of their exercising efforts, because of the valuable biofeedback that they generate. Pelvic floor exercises should become routine events in women's lives, but especially before and after childbirth, hysterectomy and the menopause . Types of Incontinence • Urge Incontinence – Involuntary loss of urine associated with a strong urge to void that cannot be suppressed. Treatment- – • • • • Biofeedback Pelvic floor nerve stimulation Bladder drill Anticholinergics anticholinergic • An anticholinergic agent blocks the neurotransmitter acetylcholine in the central and the peripheral nervous system. • An example dicyclomine. • Decreased the effects mediated by acetylcholine on acetylcholine receptors Types of Incontinence • Reflux incontinence – Involuntary loss of urine due to Hyperreflexia in the absence of normal sensation – Associated with spinal cord injuries Types of Incontinence • Overflow incontinence – Involuntary loss of urine due to over-distention of the bladder • • • • Bladder is unable to empty normally over distended frequent urination (just over flow) Incontinence – Treatment: • Catheterization Behavior Therapy Management • Fluid Management – Increase fluid – Decrease fluid – WATER!!!! • Standardized voiding frequency • • Timed voiding Bladder retraining Behavior Therapy Management • Pelvic Muscle Exercises – Kegel exercises • Goal – strengthen voluntary muscles Behavior Therapy Management • Pharmacological Therapy – Anticholinergic agents • Oxybutynin/Ditropan – – Action: Inhibits bladder contractions Indications for use: urge incontinence Surgical management • Involve lifting and stabilizing the bladder or urethra Nursing Management h fluids No diuretics after 4PM Avoid bladder irritants • • • – – – • • • • Caffeine Alcohol Aspartame (nutrasweet) High fiber meals Void regularly Enc pelvic floor exercises Stop smoking Urinary Retention • Pathophysiology – Urinary Retention • – The inability to empty the bladder completely Residual urine • – urine that remains in the bladder after voiding Assoc. with • • • • • • • post-op d/t reflux spasm of sphincters Diabetes Prostatic enlargement Urethral pathology Trauma Pregnancy Neurologic disorders Urinary Retention • Assessment – Measure post void residual urine • Portable bladder scanner Urinary Retention • Complications – – – – – Chronic infections Pyelonephritis Sepsis Kidney failure Deathmosis Urinary Retention • Nursing Management – Promoting normal urinary eliminations • • • • • • • • – Provide privacy Commode Male stand Sitz bath Hot tea Water faucet on Tapping pubic area Dipping hand in warm water Promoting urinary elimination • Catheterization Neurogenic Bladder • • A dysfunction d/t a lesion of the nervous system Two types of neurogenic bladder – Spastic bladder / reflex bladder • – Empties on reflex Flaccid bladder • • • • Bladder becomes distended Overflow incontinence Bladder does not contract Can not feel discomfort Neurogenic Bladder: Management • Catheterization – – – – – • Indwelling devices – – – • Obstruction Post-op Monitor output with critical Neurogenic bladder or urinary retention Stage III or IV decubitus ulcers Drainage bag below the level of the bladder Tubing not kinked and no too long Increase fluids Suprapubic catheterization Urological Surgery • Drainage tubes • Nephrostomy drainage – Tube inserted directly into the kidney Nephrostomy drainage • Nursing management – Assess for complications • Bleeding • Infection • Skin – – – – – – Ensure unobstruction Never clamp Irrigate Encourage fluids Aseptic technique Measure I&O Urethral Stent • A tubular device that maintains position & patency of the urethra Nursing Process: post-op urinary surgery • Ineffective airway clearance r/t the surgical incision • Ineffective breathing pattern r/t to surgical incision & general anesthesia – – – – – – – Assess resp status Auscultation Admin analgesics Splint Change position frequently Incentive spirometer Amb.
