Laparoscopic dismembered pyeloplasty: technique and results in 105 patients.

Purpose: To evaluate the postoperative and functional results of the laparoscopic dismembered pyeloplasty (LDP).

Patients And Methods: Between May 2000 and April 2008, we performed in our department 105 LDP. All patients presented an ureteropelvic junction obstruction with dilatation of renal calyx system with an enlarged renal pelvis. Demographic data (age, gender), perioperative and postoperative parameters, including operating time, estimated blood loss, complications, length of hospital stay, functional outcome were collected and evaluated.

Results: The mean operative time for LDP was 150 min (range 120-180 min) and the mean estimated blood loss was negligible in all patients. The mean hospital stay was 4 days (4-8). No conversion to open surgery occurred. In the follow-up, we noted a successful rate in 96.2% of the patients.

Conclusion: Laparoscopic dismembered pyeloplasty, if performed by expert surgeons in high-volume centres, presents results that are comparable with open surgery, with a lower surgical trauma for the patients.
