Summary
Blunt penile trauma can cause persistent erectile dysfunction due to veno-occlusive issues. Penile vein ligation effectively treated two patients, restoring near-normal erectile function and demonstrating its value for trauma-induced venous leak.
Area of Science:
- Urology
- Andrology
- Trauma Surgery
Background:
- Blunt trauma to the pelvic or perineal region is a known risk factor for persistent erectile dysfunction.
- Hemodynamic investigation of the veno-occlusive mechanism in traumatic impotence is infrequently reported.
Purpose of the Study:
- To investigate the hemodynamic basis of erectile dysfunction following blunt penile or perineal trauma.
- To evaluate the efficacy of penile venous ligation for treating trauma-induced veno-occlusive erectile dysfunction.
Main Methods:
- Case study of two young men with erectile dysfunction post-trauma.
- Combined intracavernous injection and stimulation test.
- Color duplex ultrasonography, pharmacologic cavernosometry, and cavernosography.
Main Results:
- Arterial velocity and pulsation were normal, with no evidence of arteriovenous fistula.
- Severe venous occlusion and identification of site-specific abnormal veins were observed in both patients.
- Penile vein ligation resulted in near-complete normalization of erectile function after four years.
Conclusions:
- Trauma-induced erectile dysfunction can stem from veno-occlusive dysfunction.
- Penile venous ligation, particularly targeting site-specific abnormal veins, is an effective treatment.
- Satisfactory long-term erectile function can be achieved with this surgical approach.
