Prentiss orchiopexy applied in younger age group.

PURPOSE: To evaluate the efficacy and safety of the operative technique for the correction of cryptorchidism described by Prentiss in the 1950s, who conducted measurements on patients over 6 years of age, and on cadaveric specimens. We applied the technique in a younger age group.

MATERIAL AND METHODS: We prospectively studied the results of 50 orchiopexies in children 8-59 months of age (mean 32.3 months), separated into three age groups: 8-18 (N=14), 19-36 (N=18), and 36-59 (N=18) months. The patients were selected for having their undescended testis in the inguinal canal and not reaching the scrotum after adequate inguinal and retroperitoneal dissection. We eliminated the anatomic angulation of the vas deferens and testicular vessels around the internal inguinal ring and inferior epigastric vessels, in order to improve distal scrotal positioning (Prentiss maneuver). We compared the position of the testis before and after the maneuver. We re-examined the children 1 year postoperatively for testicular position and quality.

RESULTS: The average gain in scrotal positioning was 6-20 mm (mean 13 mm). At follow-up, 36 testes (78%) had retained a low scrotal position, 10 (20%) a middle scrotal position, and 4 (8%) presented in an upper scrotal position.

CONCLUSIONS: The Prentiss maneuver is both safe and efficient when applied to the younger age group, in order to gain adequate intrascrotal cord length and to place the testis in a more distal scrotal position.
