Ureteroscope-assisted double-J stenting following laparoscopic ureterolithotomy.

The aim of this study was to examine the feasibility of ureteroscope-assisted double-J stenting following laparoscopic ureterolithotomy and to evaluate the effects of retrograde ureteroscopic access exerted on the sutured ureterotomy site. From January 2002 to December 2011, 30 patients with proximal ureteral stone underwent ureteroscopic double-J stenting of the ureter following retroperitoneal laparoscopic ureterolithotomy. Patient demographics and perioperative parameters, including the degree of hydronephrosis, urine leakage, and drainage time, were retrospectively reviewed. These data were compared with those of 30 consecutive patients who received open ureterolithotomy and intracorporeal ureteral double-J stenting. In addition, a PubMed search was conducted and the related literature on the placement of a ureteral stent was reviewed. Twenty-eight patients successfully underwent ureteral double-J stenting with ureteroscopic access. No malposition of the ureteral stent was identified in the ureteroscopic group, but two patients in the intracorporeal group required postoperative adjustment of the stent. Residual stone fragments were found during stent placement in three patients in the ureteroscopic group and holmium:yttrium-aluminum-garnet laser lithotripsy was immediately performed. There was no significant difference in postoperative outcomes or complication rates between the two groups. Ureteroscope-assisted ureteral double-J stenting is a simple and safe alternative allowing intraluminal navigation along the entire ureter, correct stent placement, and prompt treatment of residual stone fragments, without radiation exposure. In addition, ureteral disruption and urinary extravasation may not be concerns for ureteroscopic access with continuous normal saline irrigation.
