Spermatic venography in undescended testes.

T Riebel, D Gonnermann, R P Willig

    Pediatric Radiology
    |January 1, 1987
    PubMed
    Summary

    Spermatic venography precisely locates undescended testes, outperforming other imaging. This minimally invasive outpatient procedure aids surgical planning and reduces exploration extent, especially for complex cases.

    Area of Science:

    • Urology
    • Radiology
    • Pediatric Surgery

    Background:

    • Undescended testes (cryptorchidism) present diagnostic challenges, particularly with intra-abdominal or hypoplastic gonads.
    • Accurate localization is crucial for effective surgical management and preventing complications.

    Purpose of the Study:

    • To evaluate the efficacy of spermatic venography in demonstrating the pampiniform plexus for precise localization of undescended testes.
    • To compare venography's accuracy with ultrasound and computed tomography in identifying gonadal tissue.

    Main Methods:

    • Selective retrograde contrast filling of the internal spermatic vein was performed.
    • Spermatic venography was conducted on an outpatient basis in children aged 6 years and older without general anesthesia.
    • Radiologic findings were compared with surgical outcomes in 12 explored veins across 7 patients.

    Main Results:

    • Spermatic venography provided exact information on the existence and localization of gonadal tissue, superior to ultrasound and CT for small or intra-abdominal testes.
    • In 75% of cases, venographic and surgical findings corresponded completely.
    • Venographic identification of the pampiniform plexus aided in localizing the contralateral testis in remaining cases.

    Conclusions:

    • Spermatic venography is a highly accurate and minimally invasive technique for localizing undescended testes.
    • The procedure can reduce the extent of surgical exploration, especially in cases requiring repeat operations.
    • Outpatient spermatic venography is safe and effective for children, offering valuable diagnostic information for cryptorchidism management.
