Comparison of transvesicoscopic Cohen and transvesicoscopic Politano-Leadbetter ureteral reimplantation in the treatment of ureterovesical junction obstruction (UVJO) in children: a single-center long-term follow-up study.

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.
