Comparison of Dismembered and Nondismembered Y-V Laparoscopic Pyeloplasty in Patients with Primary Hydronephrosis

Abstract

LY-VP appears to be a safe, attractive alternative to LH-AP.

Dismembered Laparoscopic Anderson-Hynes Pyeloplasty Versus Nondismembered Laparoscopic Y-V Pyeloplasty in the Treatment of Patients with Primary Ureteropelvic Junction Obstruction: A Prospective Study

“…4,6,7,8,15 Three studies report similar therapeutic results. 4,6,7 Klingler and associates 8 reported a considerably lower success rate of Y-V plasty in comparison with A-H plasty, but only five patients constituted the Y-V group and all of them were operated on in the initial stages of the learning curve. Casale and coworkers 16 report the success rate of 94% for A-H plasty and 43% for Heineke-Mikulicz plasty, albeit in children.…”

“…A retrospective data analysis of 90 patients who had undergone laparoscopic pyeloplasty at our institution from 2001 to 2007 indicated that the mean operative time for A-H plasty was considerably longer then for Y-V plasty. 7 Undoubtedly, crossing vessel translocation may affect the operative time. In our study, a crossing vessel was more often observed in the Y-V group than in the A-H group (a statistically significant difference), which might account for the comparable operative times of both procedures.…”

“…7 Briefly, all patients underwent double pigtail stent (6F or 7F) placement before surgery. All procedures were performed using a transperitoneal approach through four ports.…”

“…[1][2][3][4][5][6] As far as we know, only two reports have been published so far in which the results of laparoscopic dismembered Anderson-Hynes (A-H) and laparoscopic nondismembered Y-V pyeloplasties are retrospectively compared and statistically verified, 4,7 Other studies do not provide the statistical verification of the analyzed data. 6,8 The following report is a prospective study aimed to compare two laparoscopic techniques, A-H and Y-V, in terms of their therapeutic results and intraoperative and postoperative complications.…”

Hydronephrosis in the course of ureteropelvic junction obstruction - an underestimated problem?Current opinion on pathogenesis, diagnosis and treatment.

“…42 In a study comparing laparoscopic Anderson-Hynes pyeloplasty with laparoscopic Y-V pyeloplasty, it was shown that in the Y-V plasty group operative time was significantly shorter and intracorporeal suturing was easier with similar outcomes. 43 In another study that prospectively compared success rates in Anderson-Hynes and Y-V plasty, the former resulted in a higher success rate than Y-V pyeloplasty, but the difference was not statistically significant (Fig. 3).…”
