V1-08: Primary Robotic Ureteroenteric Anastomotic Revision in Studer Neobladder: Operative Technique and Case Series

Video

INTRODUCTION

Ureteroenteric strictures occur in 3-13% of urinary diversions. Endoscopic treatment has a low long-term success rate and may subject the patient to multiple interventions and nephrostomy tubes. Open repair is considered the gold standard but is commonly avoided because of morbidity or utilized mostly after endoscopic failure. We report our technique and experience of primary robot-assisted ureteroenteric anastomotic revision in Studer neobladders (RUAR)

METHODS

We describe our operative techniques. Results of total four cases that underwent primary robot assisted revision in patients with Studer neobladders from 2013-2015 are presented. Data was collected retrospectively from medical records.

RESULTS

Two patients had right sided revisions, and two patients had left-sided revisions. The median OR time was 180 min (range 180-300). The median length of stay was 3 days (2-4). With a median follow up of 11.2 months (1.3-20.3), all patients were free of recurrent stricture. The median time to stricture after neobladder reconstruction was 2.5 months (1.3-1301), and the median time with a stent or nephrostomy tube was 3 months (1.5-6).

CONCLUSION

Primary robot-assisted revision is a feasible solution for ureteroenteric strictures in Studer neobladders with excellent intermediate success rate. As a primary repair, RUAR may avoid multiple endoscopic interventions and decrease the patient’s time with a nephrostomy or stent.
