Percutaneous antegrade endopyelotomy: long-term results from one institution.

摘要: Abstract Objectives To assess the long-term efficacy of percutaneous antegrade endopyelotomy for treatment ureteropelvic junction (UPJ) obstruction performed at a single institution during 10-year period. We provide alterations in investigation and management strategies on basis results. Methods From July 1990 to June 2001, 80 patients with clinical radiographic evidence UPJ underwent primary (n = 61) or secondary 19) obstruction. The mean patient age was 35 years (range 4 76). Percutaneous standard fashion using either hooked-knife 77) holmium laser 3). Results With follow-up 55 months 16 138), overall success rate 67% (53 79). 65% (39 60) 74% (14 19), respectively. time failure 15 1 Operative intervention 24 26 included open pyeloplasty 18, 75%), indwelling ureteral stenting 2, 8%), retrograde balloon dilation 1, 4%), nephrectomy 3, 13%). Two asymptomatic recurrent elected conservative follow-up. Significant crossing vessels were encountered (83%) 18 patients. Conclusions Our results demonstrated somewhat lower rates than that reported published studies. Long-term is critical identifying late failures. high prevalence provided further support its role failure. Routine preoperative helical computed tomography detect significant recommended. Patients are likely better served operative techniques specifically address this issue, namely laparoscopic pyeloplasty.
