Complete retroperitoneal cutaneous ureterostomy with robot-assisted radical cystectomy.

INTRODUCTION: Cutaneous ureterostomy is beneficial for older patients in a hypoalimentation state, providing less invasive options than intestinal tract reconstruction techniques. However, complications such as ileus and stoma site hernia still pose risks owing to the anatomical location of the ureter. We introduce a novel method, complete retroperitoneal cutaneous ureterostomy, performed simultaneously with robot-assisted radical cystectomy.

CASE PRESENTATION: Our technique involves extending the retroperitoneal space to minimize complications and achieve stent-free outcomes. The median procedure time for complete retroperitoneal cutaneous ureterostomy was approximately 30 min. The stent-free rates at 1 and 4 months postoperatively were 66.7% and 100%, respectively; no case of stent reinsertion after stent removal was reported.

CONCLUSION: Our approach is promising for avoiding postoperative intestinal tract complications.
