The midline preperitoneal approach to orchiopexy

Area of Science:

• Pediatric Surgery
• Urology
• Developmental Biology

Background:

• Undescended testicles (cryptorchism) present a surgical challenge, particularly when located high in the abdomen or inguinal canal.
• Traditional methods may require multiple surgical stages (staged orchiopexy) for correction.
• The spermatic cord length is a critical factor in successful testicular repositioning.

Purpose of the Study:

• To evaluate the efficacy of the midline preperitoneal approach for correcting high undescended testicles.
• To assess the technique's impact on spermatic cord length and surgical complexity.
• To determine the overall success rate of this approach in achieving scrotal positioning.

Main Methods:

• A series of 42 patients with high undescended testicles were treated using the midline preperitoneal approach.
• Preoperative gonad location was documented as abdominal (59.5%) or high inguinal (40.5%).
• Surgical outcomes focused on spermatic cord lengthening and scrotal positioning.

Main Results:

• The midline preperitoneal approach facilitated scrotal delivery of all 42 undescended testicles.
• The technique significantly lengthened the spermatic cord, reducing the distance to the scrotum.
• Staged orchiopexy was virtually eliminated for these challenging cases.
• A satisfactory anatomical result was achieved in 76.9% of patients.

Conclusions:

• The midline preperitoneal approach is an effective single-stage solution for high undescended testicles.
• This technique simplifies the management of difficult cryptorchism by addressing spermatic cord length limitations.
• The approach offers a high rate of satisfactory anatomical outcomes, improving patient results.
