Antegrade versus retrograde stenting in laparoscopic pyeloplasty.
OBJECTIVE
To compare operative times between retrograde and antegrade ureteral stenting as part of laparoscopic pyeloplasty.


METHODS
Laparoscopic pyeloplasty procedures from January 2002 to January 2007 were identified through a prospective database. Procedures on 126 patients were performed using the same transperitoneal technique apart from the method of stent placement, which was performed in either a retrograde manner before laparoscopy or an antegrade manner during the laparoscopic portion of the procedure.


RESULTS
A total of 45 patients underwent antegrade stenting, 53 had retrograde stenting, 20 patients already had a stent in place, and 8 patients had retrograde pyelography followed by antegrade stenting. Operative time in patients with antegrade stent placement was significantly faster than in those with retrograde stent placement (median 185 v 245 min, P < 0.0001 [two-way analysis of variance]), even when the variability of the operative surgeon was taken into account. There was no difference in the complication rates.


CONCLUSIONS
Antegrade stent placement results in a significantly faster overall operative time when compared with retrograde stent placement.
