Introduction:
A retrospective study was performed to compare the results of dismembered and nondismembered Y-V laparoscopic pyeloplasties and the complications observed after the two types of surgery.
Materials And Methods:
Eighty-eight patients with ureteropelvic junction obstruction (UPJO) underwent a laparoscopic operation. In 2 cases, an open conversion was made. A laparoscopic Hynes-Anderson pyeloplasty (LH-AP) was performed on 50 patients, whereas a laparoscopic Y-V pyeloplasty (LY-VP) was performed in 36 cases. The diagnosis of UPJO was based on a complete medical history, ultrasonography, diuretic urography (IVU), and/or diuretic renography. The mean follow-up was 29 (range, 6-66) months. Complete success was defined as the absence of any clinical symptoms, combined with a significant reduction of hydronephrosis on IVU and ultrasonography, as well as no sign of obstruction on IVU and/or diuretic renography.
Results:
The mean operative time for LH-AP was 219 minutes and for LY-VP 185 minutes. The mean hospital stay after LH-AP was 5.9 days and after LY-VP 5.3 days. The overall success rate was 91.5% (91.8% for LH-AP patients and 91.2% for LY-VP patients).
Conclusion:
LY-VP appears to be a safe, attractive alternative to LH-AP.
