urinary diversion

Provision of an alternative exit route for urine or of an alternative temporary urine store in the body, after surgical removal of the URINARY BLADDER. The ureters may be brought out on to the surface of the abdomen, implanted into the COLON or RECTUM or implanted into a substitute bladder, formed from a loop of small bowel, with an outlet through the skin or the anus.

urinary diversion

various surgical procedures involving the ureters, bladder or urethra may be used to alter the usual route of urine flow, thereby bypassing portions of the urinary tract, usually the bladder and/or urethra. Ureters, bladder or urethra are transplanted or anastomosed to the bowel or placed so urine exits at an orifice created through the skin. See also ureteroileostomy, trigonal-colonic anastomosis, ureterocolostomy, transureteroureterostomy.

urinary flow monitor

periodic measurement of the amount of urine secreted. In an anesthetized animal a catheter draining into a calibrated container is used. In a conscious animal a clamped-off, self-retaining catheter is inserted and drained at intervals. A metabolism cage is an alternative.

urinary flowmetry

the measure of urinary flow rates.

urinary incontinence

an inability to control urination with the involuntary passage of urine. Most commonly occurs in dogs due to congenital abnormalities of the ureters or urethra. Other causes include congenital or acquired defects in nervous control of micturition, neoplastic or inflammatory disease of the lower urinary tract, and prostate gland and endocrine abnormalities.

urinary obstruction

urethral or ureteral obstruction often caused by lodgement of a urinary calculus in the narrow lumen. Constriction of urethra due to hyperplastic prostate in male dogs.

urinary pole
