[A long-term follow-up study of deep penile vein resection patients].

OBJECTIVE: To study the five-year postoperative effect of the ligation and resection of the deep penile vein for the patient of erectile dysfunction (ED) caused by penile venous leakage. METHODS: Sixteen ED patients received deep penile vein ligation and resection. Observations of the penile erection had been recorded for 5 years after surgery. RESULTS: Eight cases demonstrated erectile hypofunction after 18 months postoperatively and total ED after 21-30 months of which 6 were improved by chemotherapy, and 2 showed no improvement. Seven cases remained normal and 1 case get out of touch at the 24th month postoperatively. CONCLUSIONS: The ligation and resection of the deep penile vein can be considered as an easy and effective method to treat patients of ED caused by penile venous leakage.

[Hemodynamometry of erectile dysfunction].

OBJECTIVE: To study the clinical causes of the erectile dysfunction (ED). METHODS: One hundred and thirty cases of ED were examined by hemonamometry and cavernosography with vasodilating agent. The data about penile brachial index, intracavernous pressure, maintenance flow rate, and pressure loss change were obtained and the status of the penile veins was detected. RESULTS: Among 130 patients with ED, 39 had venous leakage including penile arterial insufficiency simultaneous venous leakage in 15 patients. Various leakage sites were observed by using cavernosography. Twenty-eight patients showed deep dorsal veins only and the remaining crural veins. CONCLUSION: Hemodynamometry is effective to diagnose the cause of ED.
