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)

Secondary Outcomes (1)

  • Operative time in minutes

    At 6 months after the first stage (during the second stage)
