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.
