    Abstract:
    AIM: Cutaneous ureterostomy is the least invasive method of urinary diversion, but it carries a risk of stomal stenosis. We retrospectively examined the long-term outcome of tubeless cutaneous ureterostomy by the Toyoda method. METHODS: Since 1983, the Toyoda cutaneous ureterostomy has been performed in 97 patients (169 renal units) with a minimum follow up of 3 months. The ureteral patency rate was reviewed according to whether the stomal type was single (one ureter, one stoma) or double-barrel (two ureters, one stoma). RESULTS: After a median follow up of 23 months (range 3 to 169), a tubeless condition was achieved in 102 (82%) of 124 renal units associated with double-barrel stoma and in 35 (78%) of 45 renal units associated with single stoma. Although mild to moderate hydronephrosis was observed in 19% of patients, serum creatinine levels did not change after a minimum of 12 months after surgery (median 35). CONCLUSIONS: A high ureteral patency rate was achieved with cutaneous ureterostomy using the Toyoda method. This procedure, especially double-barrel stomal creation, is a reasonable alternative to other forms of urinary diversion in patients at high risk.
