| Other Urinary Drugs | Antiseptics: Nitrourantoin Macrodantin, Analgesics: Phenazophyridine (Pyridium), Antifungals: Amphotercin B- bladder irrigation, Ketoconazole (Nizoral), Antispasmotic Hyoscyamine (Anaspaz) |
| Interventions | Nutrition Therapy: Drink 2-3L/day, Cranberry products, Avoid caffeine (bladder irritant), Pain Relief: Sitz Bath, Pyridium - changes urine to bright red orange |
| Teaching | UTI's often related to Sexual Intercourse: Urinate before/after intercourse, cotton underwear, no douching |
| Urethritis | symptoms similar to UTI, Male: STD's, Women: Post menopausal-tissue change w/low estrogen, Interventions : Antibiotic Therapy, Estrogen (topical) |
| Urethral Strictures | Causes: Obstruction*, STD's, Childbirth, Catheterization, Recurrent UTI's, Incontinence & Retention, Overflow incontinence: overdistended bladder |
| Management Urethral Strictures | Dilation of urethra stricture: temporary, Urethroplasty: remove affected area w/ or w/o grafting, Larger opening, may need to repeat procedures |
| Urinary Incontinence | INVOLUNTARY loss of urine, Normal bladder needs to contract & Urethra need to relax, Stress incontinene most common |
| Stress Incontinence | Small amounts- unable to tighten urethra enough, common after childbith, Kegel's: vaginal pelvic floor muscles thin and weakened |
| Urge Incontinence | bladder contractions, continence override signal |
| Drugs that irritate bladder (Urge Incontinence) | Caffeine, Artificial Sweetners, ETOH, Citric INtake (juices, fruits), Diuretics, Nicotine |
| Mixed Incontinence | Stress & Urge, Mostly found in older women |
| Overflow (Reflex) Incontinence | Overdistended bladder, Leaking, Underactive bladder, obstructions, neurological impairment |
| Functional Incontinence | Cognitive impairment, Dementia |
| Nursing Dx Stress Incontinence | r/t weak pelvic muscles & structural support |
| Nursing Dx: Urge Incontinence | r/t decreased bladder capacity, bladder spasms, diet, & neuro impairment, |
| Nursing Dx: Overflow (Reflex) Incontinence | r/t Neuro Impairment |
| Nursing Dx: Functional Incontinence | r/t impaired cognition or neuro limitations |
| Nursing Dx: Mixed/Total Incontinence | r/t MANY CAUSES |
| Additional Nursing Dx for Incontinence | Social Isolation, Risk For Impaired Skin Integrity, Disturbed Body Image, Risk For Infection |
| Interventions: Stress Incontinence | Diary, Exercise, Kegels, Nutrition: wt. loss, avoid bladder irritating liquids, fruits, Drug Therapy: Estrogen |
| Interventions Stress Incontinence continued | Cone Therapy: Hold weights in place & walk around, 15 min intervals 2x/day with heaviest wt & progress, Behavior Modification, Psychotherapy, Electrical Stim. |
| Surgical Interventions | Reposition bladder & urethra, often have a suprapubic cath in place until can urinate w/o residual volume >50ml |
| Bladder Training vs Habit Training | Improve bladder function for those w/URGE incontinence vs Establishing a predictable pattern for those w/FUNCTIONAL incontinence |
| Interventions for Urge Incontinence | To Prevent/manage Urge, Drug Therapy: Anticholinergis- Propantheline (Pro-banthine), oxybutynin (Ditropan), Tolterodine (Detrol), SE Block Stim of bladder contraction, Tricyclic Antidepressants w/ACh Activity Imipramine (Tofranil) Nortriptyline |
| Interventions for URGE incontinence Cont | Avoid foods w/bladder stimulating or diuretic effects, space fluids (q2hrs), Limit 2hrs before bed, Behavioral: Bladder Training- short intervals, gradually increase, Habit Training: scheduled toileting, Exercise- Kegels, Elec. Stim: vag or rec |
| Interventions for REFLEX (Overflow) Incontinence | Expected Outcome: Achieve Continence, Surgery: prostate removal or genital prolapse repair, |
| Drug Therapy for REFLEX Incontinence | Cholinergic (short-term), Bethenechol Chloride: Urecholine, impacts on bladder tone Increases bladder pressure |
| Behavioral Interventions for Reflex Incontinence | Bladder Compression: Crede Method, Valsala, Double Voiding, Splinting, & Intermittent Self Catheterization |
| Crede Method | Tugging pubic hair, Massage |
| Valsalva | Deeper breathes, exhale (pressure toward bladder) |
| Double-Voiding | Void, repeat in 3-5 minutes |
| Splinting | Pushes cycstocele back into vagina |
| Interventions for Functional Incontinence | Remain Dry- Expected Outcome, Treat reversible causes, Applied devieces: Intravaginalpessaries: Support pelvic floor prolapse, Condom Cath, Penile Clamp Dangers: can cause tissue damage or infection |
| Catheterization | Containment of incontinence: Absorbent pads, briefs, Danger: Skin B/D. Intermittent Cath, Indwelling: Skin B/D, Terminal Illness or critically Ill |
| Interventions for Mixed (Total) Incontinence | A combo of 2 or more types of incontinence, ie: Post Menopausal Women have stress & urge. Dementias: Reflex (overflow) & Functional. |
| Hypercalcemia Primary | Absorptive: Increased intestinal Calcium Absorption, Renal: Decreased renal tubular excretion of calcium |
| Hypercalcemia Secondary | Resorptive: hyperparathyroidism, Vit. D Intox, Renal Tubular Acidosis, prolonged immobilization |
| Hyperoxaluria | Primary: Genetic Secondary: diet-excess oxalate foods ie spinach, rhubarb, swiss chard, beets, cocoa, wheat germs pecans, peanuts, okra, chocolate |
| Hyperuricemia | Primary: Gout Secondary: increased production or decreased clearance of purine from myeloproliferative disorders, thiazide diuretics, carcinoma |
| Struvite | Made of magnesium ammonium phosphate and carbonate apatite; formed by urea splitting by bacteria most commonly proteus mirabilis; needs an alkaline urine to form |
| Cystinuria | Autosomal recessive defect of amino acid metabolism that precipitates insoluble cystine crystals in the urine |
| Assessment of Stones in Urinary Tract | History of having stones, SEVERE PAIN, occurs when moving through tracts, sudden, worse than childbirth, N/V, Diaphoresis, pallor, VS Elevated, BP may be low, pain causes shock |
| What to Avoid for Calcium Oxalate | Spinach, Black Tea, & Rhubarb, Decrease Sodium intake |
| What to Avoid for Calcium Phosphate | Limit animal protein to 5-7 servings/wk, never more than 2/day, may benefit from reduced calcium intake, decrease sodium intake |
| What to Avoid for Struvite (magnesium ammonium phosphate) | Limit high phosphate foods ie: dairy products, organ meats, whole grains. |
| What to avoid for uric acid | Decrease intake of purine sources ie: organ meats, poultry, fish, gravies, red wines, and sardines |
| What to avoid for Cystine | Limit animal protein intake, encourage oral fluid intake (500ml q4hrs during the day 750ml at night) |
| Prevention of stones | Drink 3L H20/day, Exercise/walk, nutrition |
| Bladder CA (Urothelial Cancer) | Hx of smoking, exposure to toxic chemicals, parasite infection, LT use of cytoxan, *BLOODY URINE, Painless, Cystoscopy, Chemotherapy, Immunotherapy of BCG |
| Surgical Procedures | Type of surgery dependent on stage of cancer, CYSTECTOMY is the best chance of cure for larger cancers |
| Ureterostomies | divert directly through the skin surface thru a ureteral skin opening (stoma). After ureterostomy, the pt must wear a pouch |
| Conduits | collect urine in a portion of the intestine, which is then opened onto the skin surface as a stoma. Must wear a pouch. |
| Sigmoidostomies | Divert urine to the large intestine, so NO STOMA is required. The pt excretes urine w/bm's, bowel incontinence may occur. |
| Ileal resevoirs | Divert urine into a surgically created pouch or pocket that functions as a bladder. The stoma is continent and the pt removes urine by regular catheterization. |
| Post Op Care After Ostomy | assess condition of stoma, Kock's pouch, penrose drain removes lymphatic fluid or other secretions, may eed to irrigate to ensure patency, No sensation of bladder fullness, need to learn new cues for voiding, prescibed times or neobladder pressure |
| Teaching Care of Ostomy | Drugs, Nutrition, Stoma, Collection Device, Cath, Observe return demo from pt/caregiver, Men:need to sit to urinate (sigmoid) and impotence after surgery, Empty, b4 going out to any function |
| Bladder Trauma | Most common cause: pelvic fx, stabilize b4 surgical repair, Sexual Assault, Penetrating or blunt injury (gunshot or stabbing), Seat belt (if bladder is full), Interventions, Surgical repair, Cystecotomy |
