The aim of the study was to describe the technique of modified laparoscopic Foley Y-V pyeloplasty-anterior Y-V plasty and the results of the operation in the authors' material. In the modified operation, a V-shaped flap is created from the anterior wall of the renal pelvis. Thus two lines of sutures are located on the anterior, easily accessible wall of the renal pelvis. Thirty-six patients were operated on using this technique from May 2005 to January 2009. One patient did not turn up for the follow-up. Complete success was observed in 34 of 35 patients (97.1%). The mean follow-up time was 24 (4-43) months. The mean operative time was 160 minutes. We did not observe any serious complications in the postoperative period. Our results seem to indicate that the anterior Y-V plasty may constitute a reasonable treatment option for patients with small or intrarenal pelvis and no dorsally crossing vessels.
