Superficial dorsal penile vein thrombosis: a little-known complication of subinguinal varicocelectomy.

OBJECTIVE

To describe the symptomatology, diagnosis and treatment of superficial thrombosis of the dorsal penile vein - the most common complication of subinguinal varicocelectomy - and analyse the possible mechanisms involved in the development of the condition.

PATIENTS AND

METHODS

The clinical records of 326 patients who underwent varicocele repair during the last 10 years was reviewed. The technique used was subinguinal varicocelectomy with arterial preservation. A mini-Doppler probe was used during surgery for artery identification. We report on the postoperative complications of varicocelectomy, with special attention to superficial dorsal penile vein thrombosis, and provide a detailed description of the anatomy of the superficial venous system of the penis.

RESULTS

Complications usually associated with varicocele surgery occurred in less than 1% of patients. However, the most common complication in our series was superficial dorsal penile vein thrombosis, which occurred in 2.1% of patients. The use of the mini-Doppler probe allowed us to identify and preserve the arteries in all 326 patients.

CONCLUSION

Subinguinal varicocelectomy with intra-operative use of a mini-Doppler probe is a rapid and safe technique. The outcomes and complications are similar to those reported for subinguinal microscopic varicocelectomy. Superficial dorsal penile vein thrombosis is a benign self-limited condition whose association with subinguinal varicocelectomy has not been previously reported.
