Abstract
INTRODUCTION: Extraperitoneal tubeless umbilical cutaneous ureterostomy is a useful urinary diversion technique for patients with shortened ureters or high risk of upper urinary tract recurrence. However, radical nephroureterectomy following this diversion has not been previously reported. CASE PRESENTATION: A 67-year-old man underwent radical cystoprostatourethrectomy with extraperitoneal tubeless umbilical cutaneous ureterostomy for high-risk urothelial carcinoma with bilateral ureteral shortening. Twenty-four months later, left-sided upper tract urothelial carcinoma was diagnosed, and laparoscopic left radical nephroureterectomy was performed. Although dense adhesions necessitated partial small-bowel resection, complete nephroureterectomy was achieved without major complications. CONCLUSION: To the best of our knowledge, this is the first report of radical nephroureterectomy performed after umbilical cutaneous ureterostomy. This urinary diversion may represent a reasonable option for selected patients at high risk of upper urinary tract recurrence.
