Comparison of clinical outcomes between laparoscopic orchiopexy and open orchiopexy in the treatment of palpable undescended testes.

Abstract

To compare the clinical effects of laparoscopic orchiopexy (LO) and open orchiopexy (OO) in the treatment of palpable undescended testes. Seventy-six children with palpable undescended testes treated in Zaozhuang Municipal Hospital from June 2019 to January 2021 were selected in this observational retrospective study. Patients were grouped according to their different surgical methods, 33 patients received OO (Open-group) and 43 patients received LO (Laparoscopic-group). The clinical outcomes of the two groups were compared, including surgical-related indicators, near and long-term surgical complications and postoperative testicular growth. Operation time, intraoperative bleeding, first ambulation time and hospitalization time in the Laparoscopic-group were lower than those in the Open-group (p<0.05). The short-term complication rate in the Laparoscopic-group was lower than that in the Open-group (2.27% vs 15.15%; p<0.05), but the long-term complication rate in the Laparoscopic-group was not significantly different from the Open-group (4.65% vs 3.03%; p>0.05). Follow-up was up to 18 months post-operation, with the rate of testicular growth (97.67% vs 96.97%; p>0.05) and testicular volume (0.59 ± 0.14ml vs 0.58 ± 0.12ml p>0.05) not significantly different between the Laparoscopic-group or Open-group respectively. LO is as clinically effective as OO in the treatment of palpable undescended testes, however, shorter operation time, less intraoperative bleeding and rapid recovery time have been noted with LO.
