Abstract:
Objective:To summarize the clinical effect of laparoscopic medial umbilical ligament dissection in two-stage Fowler-Stephens orchiopexy (FSO).Methods:A case-series study was conducted.Clinical data of children who underwent two-stage FSO from March 2020 to July 2022 in the Department of Urology, Children′s Hospital Affiliated to Zhengzhou University were retrospectively analyzed.Indexes such as operation time, amount of blood loss, degree of postoperative pain in the operative area, testicular position, size, texture and parental satisfaction at the operative side 1 month, 6 months and 1 year after surgery were collected.Measurement data of normal distribution were expressed as Mean± SD and compared using the independent sample and paired sample t-tests. Results:A total of 18 children with complete clinical data were included in this study.Their age ranged from 7 months to 10 years, with an average of 2 years.There were 10 cases of FSO on the left side and 8 cases on the right side.Twelve cases (group A) had the testis directly descending to the scrotum without amputation of the umbilical medial ligament during the operation, including 7 cases on the left side and 5 cases on the right side; 6 cases (group B) with testis not descending to the scrotum received amputation of the umbilical medial ligament, and the testicle was pulled into the scrotum without tension, including 3 cases on the left side and 3 cases on the right side.The age of patients in group A [(0.88±0.26) years] was lower than that in group B [(4.32±2.96) years] ( t=-4.11, P<0.05).The operation time of patients in group B was (47.50±1.87) min, slightly longer than that in group A [(46.17±1.47) min] ( t=-1.66, P>0.05).The intraoperative bleeding volume in group B was (5.18±0.42) mL, slightly higher than that in group A [(4.96±0.20) mL] ( t=-1.56, P>0.05).Patients in both groups had mild pain in the operative area, which could be tolerated by the children.There were no significant differences in testicular position, size, texture and satisfaction between the two groups 1 month after surgery.Reexamination at 6 months after operation showed that 1 case in group A had mild testicular retraction, located above the scrotum; no significant testicular retraction was observed in group B; the size and texture of testis in both groups had no significant change compared with those before operation, and the blood supply was normal according to the color ultrasound findings; parental satisfaction was high.Reexamination at 1 year after operation showed that 1 case of testis in group A was located above the scrotum, 2 cases had no obvious development, and the rest cases had increased testis size [(0.51±0.03) mL] compared with before operation [(0.31±0.02) mL] ( t=-22.97, P<0.05); all cases of testis in group B returned to normal position, 1 case had no obvious development, and the rest cases had increased testis size [(0.45±0.02) mL] compared with before operation [(0.24±0.01) mL] ( t=-32.87, P<0.05).There was no significant difference in testicular size increase between group A [(0.20±0.03) mL] and group B [(0.20±0.01) mL] ( t=-1.19, P>0.05). Conclusions:In the case that the medial umbilical ligament obviously affects the testicular descent, it can be dissected, which significantly shortens the distance of testis descending to the scrotum.The testicular position after surgery is normal, and the two-stage FSO does not affect the testicular development.
