This is a comparative study to see the outcome of yransection versus ligation of internal
spermatic vessels in first stage laparoscopic Fowler-Stephens orchidopexy for
intra-abdominal testis in assisting the descent of the testis to the base of scrotum
during the second stage

Transection Versus Ligation of Internal Spermatic Vessels in Laparoscopic Fowler-Stephens Orchidopexy

Cryptorchidism

Cryptorchidism is one of the most commin congenital deformities of male newborns, known
as undescended testis (UDT). The incidence ranges according to gestational age, affecting
1.0-4.6% of full-term infants and 1.1-45% of preterm infants. (UDT) is a condition in
which the testicles are not found at the base of the scrotum. Studies have shown that the
undescended testicle has a potential of spontaneous descent during the first 3 months of
life and is less likely to do so after 6 months of age. In almost 20% of cases the
undescended testes are not palpable, increasing the difficulty of investigations and
treatment, and 30% of these cases are also intra-abdominal. If UDT left untreated, it can
cause histological alterations of the testicular cells and increasing of the risks of
infertility.

As of treatment of UDT, laparoscopic surgery is ,for most surgeons, the preferred
technique. Several techniques have been described for laparoscopic orchidopexy. After
spermatic vascular transection, single-stage testicular descent fixing was carried out,
as Fowler and Stephens (FSO) first described in 1959. Since 1996, a two-stage
laparoscopic Fowler-Stephens technique involving preservation of the gubernacular vessels
and performing an entirely laparoscopic second stage. The second stage is presently
performed 6-9 months after the first.

Recently, laparoscopic FSO has been adopted to treat high-level IATs, for its minimally
invasive wound and acceptable success rate.

Transection Versus Ligation of Internal Spermatic Vessels in First Stage Laparoscopic Fowler-Stephens Orchidopexy for Intra-abdominal Testis. Randomized Study

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.

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.

After either of transection or ligation of the spermatic vessels during the first stage
of laparoscopic Fowler-Stephens orchidopexy, the operative time in minutes of the second
stage will be measured and compared among the two groups.
