Gubernaculum-sparing orchiopexy versus gubernaculum excision; A randomized trial on success and atrophy rates.

Previous studies showed that extra blood supply can decrease testicular atrophy following laparoscopic orchiopexy. We evaluated the impact of preserving the gubernacular attachment (which contains blood supply from cremasteric artery and its anastomoses) on atrophy rates following open conventional orchiopexy. This double-blinded randomized trial was implemented from March 2022 to September 2023. Included boys with non-palpable testis, even with examination under anesthesia, underwent diagnostic laparoscopy to evaluate the testis's location and size. Nubbin testes and those with > 2-cm distance from the internal inguinal ring. Participants were assigned into two groups (gubernaculum sparing (GS) and excision (GE)) by permuted block randomization. Overall success was defined as achieving both morphologic success (atrophy <20% of the intraoperative size) and anatomical success (scrotal or high-scrotal locations). Boys were followed at three- and six-month post-surgery via ultrasound. Independent t-test, repeated ANOVA, and Friedman's tests were used where appropriate. Of 92 boys (105 UDTs overall), 75 testes (36 in GS, 39 in GE groups) were used in the analysis. The mean age of participants was 25 ± 17 months (range 6-84). The mean testis size of cases intraoperatively was 460 ± 226, 396 ± 166, and 520 ± 258 mm Although mean testicular volume decreased in both groups, we found superior morphologic and overall success rates among the GS group. The greatest size reduction was noted at the three-month post-surgery compared to the six-month checkpoint. https://irct.ir/trial/58842.
