Show Summary Details

Quick Reference

n. the operation of implanting the ureters into the sigmoid colon (see ureteroenterostomy). This method of permanent urinary diversion may be used after cystectomy or to bypass a diseased or damaged bladder. The urine is passed together with the faeces, and continence depends upon a normal anal sphincter. The main advantage of this form of diversion is the avoidance of an external opening and appliance to collect the urine; the disadvantages include possible kidney infection and acidosis with long-term development of new tumours in 10% of cases.
