Ureteral Bladder Sleeve Resection

En bloc excision removes the diseased distal ureter and adjacent bladder wall as one specimen. This preserves their relationship for pathologic assessment and supports evaluation of whether the tumor has been completely removed. Surgical margin assessment is therefore central to judging the local adequacy of the operation and guiding subsequent management.

Kidney preservation is the principal rationale for selecting this approach in appropriate cases. By focusing treatment on a localized distal ureteral lesion and its adjacent bladder wall, the operation can preserve the remaining urinary tract when complete removal is feasible. This makes it a kidney-sparing option for selected distal ureteral urothelial carcinomas.

Histopathologic examination converts the removed tissue into information used beyond the operation itself. It helps establish tumor stage and can influence further management after resection. Because the specimen includes the diseased ureteral segment and bladder cuff, its assessment also accompanies evaluation of surgical margins, linking tissue findings to local control and ongoing care.

The central workflow includes excising the diseased ureteral segment and bladder cuff en bloc, assessing surgical margins, and reconnecting the healthy ureter to the bladder. Reconnection occurs through ureteral reimplantation, which restores continuity after the distal segment has been removed. These steps combine tumor removal, pathologic assessment, and urinary tract reconstruction in one treatment sequence.

The approach is most relevant when disease is localized to the distal ureter and complete removal can be achieved. In that setting, resection may provide local tumor control for selected distal ureteral urothelial carcinomas while preserving the remaining urinary tract. Histopathologic findings then help determine staging and whether additional management is appropriate.

Postoperative surveillance looks for two clinically important outcomes: tumor recurrence and urinary obstruction. Monitoring remains necessary after excision and ureteral reimplantation because the procedure addresses the original localized lesion but does not end follow-up. Surveillance extends care beyond immediate treatment, helping clinicians identify recurrence or impaired urinary drainage during subsequent management.
