Introduction:
Here we describe our technique for robot-assisted, extravesical, anterior wall ureteral reimplantation for select patients with obstructive megaureter or high grade VUR with paraureteral diverticulum. We performed anterior wall reimplantation, extrapolating our experience with anterior wall appendicovesicostomy [Famakinwa et al., Eur Urol 2013;64(5):831-6]
Methods:
We applied this technique at our institution for a total of 6 patients: 4 pediatric, 2 adult. Amongst our pediatric patients, 3 underwent surgery for obstructive megaureter, and 1 for a paraureteral bladder diverticulum with high grade VUR. Our 2 adult patients opted for surgery in the setting of distal ureteral strictures. To avoid ureteral kinking, we perform detrusorotomy in alignment with the ureter, and take care to avoid ureteral laxity during reimplantation.
Results:
Following surgery, each of our 6 patients continues to remain without evidence of obstruction, including ureteral kinking, with follow-up ranging from 3 months to 5 years. No procedural-related complications have been noted to date.
Conclusion:
We have found this approach to be technically straightforward, avoiding intravesical dissection and associated morbidity of bladder spasm, while achieving functional outcomes.
