Summary

The aim of this study was to evaluate the role of flexible cystoscopy in preventing malpositioning of the ureteral stent after laparoscopic ureterolithotomy in male patients.

From April 2009 to June 2015, 97 male patients with stones \>1.8 cm in the upper ureter underwent intracorporeal double-J stenting of the ureter after laparoscopic ureterolithotomy performed by four different surgeons. In the last 50 patients who underwent laparoscopic ureterolithotomy flexible cystoscopy was performed through the urethral route to confirm the position of the double-J stent, while in the first 47 correct positioning of the stent was confirmed through postoperative KUB.

Conditions

  • Urinary Stones
  • Ureteral Calculus

Interventions

DEVICE

flexible cystoscopy

After intracorporeal insertion of the double-J catheter, additional endoscopic monitoring with flexible cystoscopy was performed. The surgeon manipulating the double-J catheter used monitor A, while an assistant inserted a flexible cystoscope into the bladder through the urethral route and determined whether the double-J stent was correctly placed in the bladder using monitor B before suturing the site of ureterotomy. If the stent was well-placed, the flexible cystoscope was withdrawn. If the double-J stent was not visualized in the bladder, the surgeon pushed the stent inferiorly using a laparoscopic instrument and monitor A until the stent came out through the ureteral orifice on monitor B.
