PURPOSE

The surgical treatment of intraabdominal/proximal groin testis can be challenging. Beneath a lapa-

roscopic approach and the popular Fowler-Stephens method, the Koff procedure, implying a low

ligation of the spermatic vessels might be an option in such cases. In contrary to the common

Fowler-Stephens technique, the Koff procedure has never been evaluated compared to laparo-

scopic orchidopexy.

MATERIAL AND METHODS

The present study retrospectively evaluated all patients undergoing either laparoscopic orchi-

dopexy (without vascular dissection) or single staged Koff procedure between 2009- 2016 at our

department. All boys included presented with testis lying at the internal inguinal ring, where both

approaches were a theoretical option.

RESULTS

We included 50 patients of which 24 boys (26 testis, 24/26 non palpable during operation, median

age 14.1 months) underwent a laparoscopic orchidopexy and 26 boys (28 testis, 23/28 non pal-

pable during operation, median age 15.7 months) an inguinal Koff procedure, partly after orienting

laparoscopy.

In the Koff group, after a mean follow up of 12.4 months 96% (27/28) had a viable testis in a scrotal

position.

In the laparoscopy group two patients (7%) needed a second operation due to recurrence. After

a mean follow-up of 11.7 months 100% of the testis after laparoscopic orchidopexy were viable and

stayed in a scrotal position.

CONCLUSIONS

The Koff procedure is a safe and feasible approach in boys with abdominal testis close to the

internal ring/peeping testis. The success rate of this vessel dissecting inguinal approach is - in our

hands - comparable to a vessel sparing laparoscopic orchidopexy.
