Objectives:We retrospectively evaluated our experience with a relatively uncommon procedure, the laparoscopic ureterolithotomy, for the treatment of ureteral stones. Methods: Between April 2002 and October 2006, a total of 74 patients (56 males, 18 females) with upper (54 cases), middle (18 cases) and lower (two cases) ureteral stones underwent laparoscopic ureterolithomy. The mean age was 39.4 years (range, 19-74). The stones were in the right side in 44 cases (59.5%) and in the left side in 30 (40.5%) cases. The mean stone size was 1.8 cm (range 1.5-2.8). The procedure was retroperitoneal in 66 cases (89.2%) and transperitoneal in eight (10.8%) cases. Laparoscopic guided flexible ureterorenoscopic extraction of kidney stone was carried out in one case as an adjuvant procedure. The ureter was stented and not sutured in 64 cases (86.5%). Results:The procedure was successfully completed in 94.6% of cases and an open conversion was carried out in four (5.4%) patients. The mean operative time was 58.7 min, and the mean blood loss was 90.6 mL. No major complications were encountered. Prolonged urinary leakage occurred in one patient. The mean hospital stay was 6.4 days. One patient developed ureteral stricture during follow up and was treated by endoscopic dilatation and stenting. Conclusion: In our experience laparoscopic ureterolithotomy represents a safe and effective treatment option for ureteral stones either as primary for large impacted stones or as a salvage procedure after failed shock wave lithotripsy or ureteroscopy. This procedure fulfills the advantages of minimal blood loss and analgesia requirements, good cosmetic appearance, short hospital stay and convalescence period.

We suggest an isosceles triangle between the instruments with an angle between 25 degrees and 45 degrees and an angle of <55 degrees between the instruments and the horizontal line as the optimal geometry for intracorporeal suturing. These data should be considered when planning a reconstructive laparoscopic procedure (i.e., alignment of trocars, table position). However, further studies are required to confirm these preliminary results.

Our preliminary results with a response rate of 59% with ESWT for Peyronie's disease, including a 17% complete remission rate, is encouraging. However, further multicenter studies will have to prove if ESWT is a real therapeutic option for this disease.
