Abstract

Background: Junction obstruction in the ureter is a high-prevalence disorder and its standard treatment is dismembered method. This study aimed to evaluate laparoscopic transposition of lower-pole kidney crossing vessels in patients with ureteropelvic junction obstruction, before and after surgery, in a 5-years follow-up study. Methods: In this cross-sectional study, 24 patients with lower pole crossing vessels underwent laparoscopic surgery of transposition of crossing vessel were enrolled. For patients, diethylene triamine pentacaetic acid (DTPA) scan was performed before, and 1 and 6 month after the surgery and they were followed yearly for 5 years. Findings: Twenty four patients with a mean age of 28.04 ± 12.99 years (58.3% male) and 3.29 ± 0.69 days of stay in hospital, suffering from stenosis of ureteropelvic junction were enrolled. Mean blood loss was 151.99 ± 7.48 ml. In all the patients, kidney function improved after the surgery (the Moffitt surgery: 100%). Conclusion: Laparoscopic transposition of aberrant vessels has a success rate of a hundred percent in improving the renal function and it also has the lowest rate of complications and hemorrhage. Further studies with control groups are recommended to compare the results of this method with older methods, especially in people under the age of 2 years. © 2017, (publisher Name).
