Objective:To compare laparoscopic Anderson-Hynes pyeloplasty(LAHP)and retroperitoneal laparoscopic YV-pyeloplasty(LRYVP)in ureteropelvic junction obstruction(UPJ)in presence of a crossing vessels(CV).Methods:Our database showed 380 UPJO-cases,who underwent laparoscopic retroperitoneal surgery during the last 2 decades including 206 non-dismembered LRYVP,157 dismembered pyeloplasties LAHP,and 17 cases of laparoscopic ureterolysis.Among them 198 cases were suitable for a matched-pair(2:1)analysis comparing laparoscopic retroperitoneal non-dismembered LRYVP(Group 1,n Z 131)and dismembered LAHP(Group 2,n Z 67)in presence of a crossing vessel.Patients were matched according to age,gender,kidney functions,and obstruction grade.Complications were graded according to modified Clavien-classification.Results:Comparative data were similar between both groups(LRYVP vs.LAHP)including mean operating time(112 min vs.114 min),complication rates(4.2%vs.7.3%)mainly Grade 1e2 according to Clavien classification,and success rates(90%vs.89%).These results reflected in the reviewed literature indicate that LRYVP provides the advantage of minimal dissection in case of CV with similar outcome.However,redundant pelvis and anteriorly crossing vessels still require a dismembered pyeloplasty LAHP.Conclusion:LRYVP has achieved similar results compared with the previous golden standard of open surgery,especially in case of crossing vessels apart from presence of a redundant pelvis or anteriorly crossing vessel.This can be further improved when using the small access retroperitoneoscopic technique respectively mini-laparoscopy.
