Transverse testicular ectopia corrected by a modified Ombrédanne operation

Area of Science:

• Urology
• Pediatric Surgery
• Developmental Biology

Background:

• Transverse testicular ectopia (TTE) is a rare congenital anomaly where both testes are found on the same side of the scrotum.
• It is often associated with other genitourinary abnormalities and can be mistaken for cryptorchidism.
• Previous surgical history, such as inguinal hernia repair, can complicate the presentation and management of TTE.

Observation:

• The case involved a patient with a history of left inguinal hernia repair.
• The right testis was initially absent from the scrotum.
• Post-operatively, both testes were positioned on their respective sides, but the right vas deferens was found to traverse the left inguinal canal.

Findings:

• The surgical intervention successfully positioned both testes, but identified an unusual anatomical course of the right vas deferens.
• This finding suggests a complex developmental pathway or a consequence of prior surgery.
• The modified Ombrédanne operation was utilized to address the testicular positioning.

Implications:

• This case highlights the importance of thorough pre-operative assessment in patients with a history of inguinal surgery and suspected testicular anomalies.
• Understanding the aberrant course of the vas deferens is crucial for successful surgical correction and preventing future complications.
• Reporting such cases contributes to the literature on rare urogenital developmental anomalies and surgical techniques.
