Abstract
PURPOSE: To compare the outcomes of transvesicoscopic Cohen ureteral reimplantation (Cohen technique, Cohen group) and transvesicoscopic Politano-Leadbetter ureteral reimplantation (Politano-Leadbetter technique, Politano-Leadbetter group) in the treatment of ureterovesical junction obstruction (UVJO) in children. METHODS: From March 2008 to January 2024, 105 patients underwent Cohen technique and 87 underwent Politano-Leadbetter technique. The demographic data, perioperative parameters, surgical outcomes, and postoperative complications of the two groups were analyzed and compared. RESULTS: The operation time in the Cohen group was shorter than that in the Politano-Leadbetter group (128.2 ± 30.7 vs. 143.1 ± 31.5 min, p < 0.05), but the improvement in hydronephrosis 6 months after surgery in the Politano-Leadbetter group was better than that in the Cohen group (1.48 ± 0.73 vs. 1.63 ± 0.57 cm, p < 0.05). The success rates in the two groups were similar (97.1% vs. 96.6%, p = 0.855). There was no statistical difference in postoperative hematuria time, catheter retention time, hospital stay, and improvement in ureteral dilation between the two groups. CONCLUSIONS: Two minimally invasive surgical methods via the bladder approach for UVJO have a similar results. Compared to Cohen technique, Politano-Leadbetter technique without change the direction of the ureter, but the surgical time is longer.
