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.
the measure of urinary flow rates.
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.
