Testicular venography in the nonpalpable testis.

Area of Science:

• Radiology
• Urology
• Pediatric Surgery

Background:

• Undescended testes, or cryptorchidism, affect a significant number of pediatric and adult patients.
• Accurate localization is crucial for surgical planning and improving outcomes in cases of nonpalpable testes.
• Testicular venography has been explored as a diagnostic tool for identifying the location of impalpable testes.

Observation:

• This study evaluated the efficacy of testicular venography in 15 patients (3-39 years) with 21 nonpalpable testes.
• Fourteen successful venograms were performed, identifying testes in retroperitoneal, inguinal canal, and superficial inguinal pouch locations.
• Left testicular vein catheterization was more successful (79%) than right-sided (42%).

Findings:

• Testicular venography accurately localized nonpalpable testes in 14 out of 21 cases.
• The pampiniform plexus was key for successful testicular localization via venography.
• True agenesis was suspected in three cases, and one venogram was performed post-orchiectomy.

Implications:

• Testicular venography is a valuable tool for precisely locating nonpalpable testes, guiding surgical interventions.
• The findings highlight the higher success rate of left-sided venography, potentially influencing procedural approaches.
• Accurate localization can prevent unnecessary surgeries and improve the management of cryptorchidism.
