Surgical and morphological outcome of one-stage laparoscopic orchidopexy with preservation of gubernaculum and interruption of spermatic vessels in comparison to two-stages fowler–Stephens's orchidopexy technique with preservation of gubernaculum for impalpable testis

Background
For the care of nonpalpable testis, laparoscopy has acquired complete acceptability in both diagnostic and therapeutic settings. Standard laparoscopic for situations where the length of the spermatic arteries can prevent tension-free testicular mobilization in the scrotum, Fowler-Stephens’ (F-S) orchidopexy is a widely used and acknowledged procedure. Maintaining a healthy testis’ vascularity requires gubernaculum sparing with testicular vessel cutting. Our research recommends using the F-S approach with the preservation of the gubernaculum in a single stage rather than two phases for the same outcomes. Setting: the pediatric surgery outpatient clinic at hospitals affiliated with Ain Shams University and the Armed Forces Hospitals.
Patients and methods
This was a Randomized controlled clinical trial (RCT), conducted on boys with nonpalpable testicles between 1 and 6 years old, in 2 Egyptian pediatric surgery units, between October 2019 and September 2022. The patients who met the inclusion criteria were divided into two groups to compare their outcome (atrophy and success rate): (group A with 25 impalpable testicles was subjected to one-stage laparoscopic assisted orchidopexy with interruption of spermatic vessels and preservation of the gubernaculum, while group B with 25 impalpable testicles was subjected to two-stages laparoscopic assisted orchidopexy with interruption of spermatic vessels and preservation of the gubernaculum).
Results
The mean age of all patients was (3.9±1.8), 113 nonpalpable testicles were examined during the period of our study, and 50 nonpalpable testicles met our inclusion criteria. They were divided into two groups according to surgical procedure. There were no significant differences between the two groups according to age, and preoperative testicular volume. Postoperative outcome (atrophy and success rate) had no significant differences. Operative time and hospital stay were statistically decreased in the group performed with one stage.
Conclusion
To conclude, one-stage laparoscopic F-S orchidopexy with preservation of gubernaculum is as effective as two-stage laparoscopic F-S orchidopexy with preservation of gubernaculum.
