Modified laparoscopic Y-V pyeloplasty: experience of a single center

The aim of this study was to compare the results of two procedures: laparoscopic Foley Y-V pyeloplasty and our modification of the technique. Sixteen operations performed were Foley Y-V plasties (LY-VP), and 23 were the modifications (LY-V1P). In the modified version, a V-shaped flap was created from the anterior wall of the renal pelvis. Ultrasonography, diuretic urography, and/or diuretic renography were used to diagnose ureteropelvic junction obstruction. The mean follow-up was 30 months. Complete success was defined as the absence of any clinical symptoms combined with a significant reduction of hydronephrosis on diuretic urography and ultrasonography as well as no sign of obstruction on diuretic urography, diuretic renography, and/or the Whitaker test. We did not observe any serious postoperative complications. The success rate was 93.3% for LY-VP patients and 95.4% for LY-V1P patients. The modified plasty group had easier intracorporeal laparoscopic suturing while maintaining similar postoperative outcomes.
