Purpose: Cutaneous ureterostomy is a less invasive method of urinary divers
ion and an attractive option especially in patients at high risk. We retros
pectively examined the long-term outcome of the method introduced by Toyoda
.
Materials and Methods: Since 1983 the Toyoda cutaneous ureterostomy has bee
n performed in 61 patients (103 renal units) with a minimum of 3 months of
followup. The ureteral patency rate was reviewed.
Results: Of the 92 renal units (89%) that achieved a tubeless condition 53
(51%) had no hydronephrosis, 23 (22%) had mild to moderate hydronephrosis w
ithout the need for treatment, 14 (14%) were not evaluated during followup
and 2 (2%) were removed due to subsequent renal pelvic and/or ureteral carc
inoma.
Conclusions: A high ureteral patency rate was achieved with the Toyoda cuta
neous ureterostomy. This procedure is a reasonable alternative to other for
ms of urinary diversion.
