Background
If endourological approaches are not applicable to treat vesicoureteral anastomotic complications after kidney transplantation, the surgical gold standard in many transplant centers is pyeloureterostomy or ureteroureterostomy using the native ureter. We report an original preperitoneal technique that can be used for vesicoureteral reanastomosis in kidney transplant recipients not eligible for endourological treatment.
Methods
Between January 2011 and December 2015, 18 kidney transplant recipients underwent this new surgical procedure. Of this number, 15 subjects with at least 1 year of follow-up were included in the analysis. The indications were vesicoureteral reflux, anastomotic stenosis, and leakage in 8, 5, and 2 patients, respectively. Briefly, a double J stent was preoperatively inserted into the grafted ureter. Surgery was performed through a Pfannenstiel incision. The preperitoneal space surrounding the bladder was dissected and the distal part of the grafted ureter was identified and mobilized. The anastomotic area was resected and another vesicoureteral anastomosis was performed (Lich–Gregoir technique), keeping the JJ stent in place for three weeks.
Results
This procedure was performed 213 days (range 17–2608) after kidney transplantation. Median surgical duration was 179 minutes (range 112–314) and median hospital stay 8 days (range 4–14). The success rate was 86.7% (13/15), with a median follow-up of 1148 days (range 517–1808). In two patients, symptomatic recurrence of vesicoureteral reflux required a pyeloureterostomy using the native ureter.
Conclusions
The authors describe a simple technique that avoids transperitoneal dissection, potentially yielding more esthetic results thanks to easy access, as well as excellent outcomes.
