Evaluation of one-hundred open-ended vasectomies

Open-ended vasectomy was performed on one-hundred men. Sixty-three of them showed up for follow-up six months later. Spontaneous recanalisation had occurred in two. Sperm granuloma without orchialgia was found in 14 out of 59 men (23.9%). Twenty-one out of the 63 thought their sex life had improved, while 40 thought it was unchanged; only one man mentioned pain during intercourse since vasectomy.

Vasitis nodosa and spermatic granuloma of the skin: an histologic study of a rare complication of vasectomy

A 29-year-old man noticed localized painful swelling of the scrotal skin after elective vasectomy. The lesion was excised and its histologic examination revealed a diffuse inflammatory, partly granulomatous infiltrate with numerous tubular structures in the dermis and subcutaneous tissues. These ductules were lined by cuboidal epithelial cells and contained spermatozoa. The inflammatory infiltrate consisted of lymphocytes, plasma cells and histiocytes, but also contained spermatozoa and a few spermatic granulomas. These changes were the sequelae of a vasocutaneous adhesion and fistula; the ductules were the result of epithelial regeneration from the vas deferens and the inflammation with spermatic granulomas was due to extravasated spermatozoa.

Spermatic cord arteriovenous fistula: an unusual complication of vasectomy

A case of a large, symptomatic spermatic cord arteriovenous fistula following routine vasectomy is reported. This unusual complication required surgical intervention and has not been noted previously.

A late post-vasectomy syndrome

A group of 20 surgical specimens in 18 patients with a previously unappreciated syndrome of unremitting epididymal pain and induration 5 to 7 years after vasectomy was collected during a 2-year interval. These symptoms uniformly were unresponsive to conservative measures, including empiric antibiotics. Total unilateral or bilateral epididymectomy and partial vasectomy led to complete relief of symptoms, usually within 24 hours. Pathological examination of the specimens revealed features consistent with sequelae of long-standing obstruction. Recognition of this late post-vasectomy syndrome, which represents a major complication of vasectomy, might be expected to increase as cohorts of vasectomized individuals age.
