Description:
<jats:p>Background: The minimally invasive implementations of the established open methods for the correction of primary vesicoureteral reflux have proven to be successful in terms of feasibility and safety. The aim of this study was to investigate to what extent pediatric patients benefit from vesicoscopic operations. Methods: Between 2010 and 2022, 224 children (359 ureters) underwent ureteral reimplantation for vesicoureteral reflux in our clinic. Children, operated on according to the COHEN technique, underwent an open approach in 39 cases, whereas 151 patients were operated on vesicoscopically. A total of thirty-four children have received a ureteral reimplantation according to the LEADBETTER-POLITANO technique: twenty-nine openly and five vesicoscopically. The open and vesicoscopic groups were compared with regards to perioperative data and postoperative course. Results: The mean operating time was significantly shorter for open than for the vesicoscopic procedures in the COHEN group (99 vs. 149 min, p < 0.001). Similarly, a comparison of ureteral reimplantations, according to LEADBETTER-POLITANO, favored the open procedure, although this was not significant (161 vs. 196 min, p = 0.135). There was no significant difference in the recurrence rate of all the groups. All procedures remained within the accepted range with a success rate of at least 96%. In the postoperative course, a significantly shorter hospital stay (4.1 vs. 7.9 days, p < 0.001 for COHEN-patients; 5.6 vs. 9.2 days for LEADBETTER-POLITANO-patients), as well as a significantly lower need for continuous analgesic administration, was observed for the vesicoscopic approaches of both methods (0.8 days in both vesicoscopic groups vs. 3.7 resp. 3.8 days in open groups, p < 0.001). In addition, the time of bladder drainage was significantly shorter in open techniques (7.2 vs. 1.9 days, p < 0.001 for COHEN-patients; 3 vs. 8.7 days for LEADBETTER-POLITANO-patients). Conclusions: For almost all underlying causes, the surgical treatment of vesicoureteral reflux can be performed vesicoscopically, even if bilateral, in one session. Patients benefit significantly from the use of minimally invasive surgery in the postoperative course with faster mobilization, less need for analgesics, a shorter bladder drainage and a reduced hospital stay, compared with its open counterparts.</jats:p>
