OBJECTIVE: To evaluate the preliminary results of retroperitoneoscopic pyeloplasty (RP) for the treatment of primary @entity3161 (PUPJS) in terms of operating time, operative and @entity260 , clinical functional and radiographic results, length of hospital stay and resumption of physical activity. MATERIAL AND METHODS: From November 1997 to June 2000, from a consecutive series of 59 @entity1 treated for an @entity154 (UPJ), the 29 @entity1 (18 females and 11 males, mean age: 35.6 years [range: 17-68]) operated by RP for PUPJS (bilateral in one case) were reviewed. Twelve @entity1 presented a lower pole vascular pedicle and 24 @entity1 had an extrasinusal renal pelvis. The RP technique was identical for all @entity1 (4 ports) and the UPJ repair was performed according to the technique described by Anderson-Hynes and K  ss (28 cases) or Y-V plasty (2 cases). RESULTS: The mean operating time was 150 minutes (range: 120-240) and the mean hospital stay was 4.2 days (range: 3-10). There were no intraoperative complications, but one conversion (3.3%) was necessary because of major adhesions. @entity260 (23.3%) consisted of: four @entity293 with one case of acute @entity2885 , perirenal haematoma, @entity2478 in the Redon drain due to obstructed double J stent, migration of the double J stent underneath the @entity254 leading to unstentable cicatricial stricture (treated by open pyeloplasty 3 weeks later). With a mean follow-up of 19.7 months (range: 7-40), 28 @entity1 were asymptomatic and one @entity1 presented persistent @entity158 at 9 months with no signs of recurrence. The 3-month IVU, performed in 27 @entity1 , showed reduction of @entity3041 in 85.7% of cases and a patent ureteropelvic junction in 96.3% of cases. Complete resumption of physical activity and return to work were possible an average of 1 month postoperatively (a fortnight for the population under the age of 40 years). CONCLUSION: PUPJS can be treated by RP according to the same principles as conventional surgery. RP pyeloplasty can be performed with an acceptable operating time and morbidity. The functional and radiological results in terms of patency of the UPJ need to be assessed in the longer term.
