Outcome Measures
Primary Outcomes (2)
testis-to-ring distance in mm at the second stage
After either of transection or ligation of the spermatic vessels during the first stage of laparoscopic Fowler-Stephens orchidopexy, the location of the testis away from the internal inguinal ring (the testis-to-ring distance in mm) will be measured during the 2nd stage (degree of descent) 6 months after the first stage and compared among the two groups.
At 6 months after the first stage (during the second stage)
Testicular volume in mL
After either of transection or ligation of the spermatic vessels during the first stage of laparoscopic Fowler-Stephens orchidopexy, the testicular volume in mL will be assessed intraoperatively during the second stage (6 months after the first stage) and compared among the two groups.
At 6 months after the first stage (during the second stage)
