Two cases of vasitis nodosa are reported hereon. The two patients were 47 and 40 year old males with desire of refertility. They were performed vasectomy 23 and 10 years ago. They were subjected to vaso-vasostomy. During the operations, spindle shaped nodules were found in the vas deferens at the site of the previous vasectomy. Histologically, they showed focal proliferation of epithelial components forming glands, where a plentiful number of sperms were present, and this was also associated with proliferative change of smooth muscle bundles of vas deferens. Some foci of spermatic granulomas were also found. This condition was similar those of salpingitis isthmica nodosa in the fallopian tube. Vasitis nodosa should be differentiated from metastatic adenocarcinoma histologically. This condition may lead to re-canalization.

Intraluminal fluid movement rate was measured in four regions of the rat epididymis. The fastest flow occurred in the proximal caput epididymis (18.5 +/- 3.7 mm/hour) and the slowest in the distal cauda (2.5 +/- 0.5 mm/hour). Vasectomy significantly reduced caput fluid flow rates unless a sperm granuloma was present at the vasectomy site. Thirty days after vasovasostomy, caput fluid movement remained reduced in animals unless a granuloma was present. Failures of this or other aspects of epididymal biology to return to normal after vasovasostomy could play a role in the frequent infertility which persists after the operation.

Review
A case of granulomatous orchitis in a 47-year-old patient is described. He had a history of recurrent pyelonephritis and subsequent chronic renal failure, and was under treatment with hemodialysis therapy. He presented with painful swelling of the right scrotal contents accompanied by fever. After the unsuccessful treatment with antibiotics, an exploration of the right scrotal contents revealed the testis replaced by a hard yellow mass. An orchiectomy was performed and granulomatous orchitis was diagnosed pathologically. The clinical and etiological aspects of this rare inflammatory disease of the testis are reviewed. It is important to recognize this disease, because this is often initially thought to be neoplastic. Although the cause of this disease is still controversial, it is supposed to be associated with sperm extravasation caused by urinary tract infection or trauma.

Previously spermatozoa in the semen of vasectomized men were reported in 62 of 63 specimens from 24 men 2 to 31 years postvasectomy (Freund and Couture, 1982). A morphologic basis and term, "microrecanalization," was proposed for this observation. Serial sections (5 mu at 200-mu intervals) of 40 specimens removed at vasovasostomy from 20 men (2 to 14 years postvasectomy) were examined and microcanals (small epithelial-lined channels) were demonstrated in 27 specimens from 18 men. In nine of the 27 specimens, spermatozoa or sperm heads were found within the microcanals. Microcanals occurred in smooth muscle, connective tissue and scar tissue, in each segment, testicular, central and abdominal, in the presence or absence of the vas deferens. Microcanal continuity was traced for 200 to 1140 microns by computerized image analysis. Microrecanalization is characterized by the absence of inflammation or sperm extravasation and is histologically distinct from vasitis nodes or sperm granuloma. Microrecanalization provides morphologic and physiologic bases for the protection of the testis and maintenance of spermatogenesis in man after vasectomy.

The lymphatic drainage of the testis, epididymis and ductus deferens was determined in unoperated and in unilaterally vasectomised Albino Swiss rats. In the vasectomised animals, the lymphatic drainage of epididymal and vasal sperm granulomas was also investigated. The normal epididymis, and sperm granulomas which develop in it after vasectomy, drain to the regional testicular lymph node via the inferior epididymal trunk; vasectomy does not interfere with this route. There is a lymphatic watershed within the middle one third of the scrotal ductus deferens; lymph may drain caudally, to enter the inferior epididymal trunk and/or rostrally to the iliac node. Lymphatics draining granulomas at the vasectomy site, may, therefore, be interrupted by vasectomy. This would contribute to, but does not fully explain, the variable immune response of the regional testicular node following vasectomy.

To establish the prevalence of vasitis nodosa in patients who had undergone vasectomy segments of vas deferens resected from 40 patients at the time of vasectomy reversal were examined histologically and immunohistochemically. The findings were correlated with clinical history and postoperative outcome. Controls comprised segments of normal vas deferens excised at vasectomy. Twenty of the 40 vasovasostomy specimens showed vasitis nodosa; in 13 this was associated with sperm granulomas and in two with spermatocoeles. The vasitis nodosa was characterised by multiple small ductules extending from the central lumen of the vas into the muscle layers and adventitia. In 14 cases there was mucinous metaplasia of the epithelium lining the ductules. The number of nerve fibres in the submucosa and muscle layers was reduced after vasectomy. In patients with vasitis, however, hyperplasia of nerve fibres in the adventitia (16 of 20 cases) and formation of neuromas were seen. Nerve fibre hyperplasia was seen in only one, and sperm granulomas and spermatocoeles in none of the 20 specimens without vasitis nodosa. The development of vasitis nodosa was independent of the patients' age or the interval between vasectomy and reversal. The restoration of fertility did not seem to be affected by previous vasitis nodosa.

Sterilization of men and women is the most popular method of contraception in Canada. The contraceptive effect of a vasectomy usually occurs within 3 months. The production of sperm, however, is not interrupted, and an increase in pressure proximal to the ligation site may cause rupture of the epididymis or the ductus deferens, with extravasation of spermatozoa and the formation of granulomas or sperm antibodies. Increased pressure may also explain the postvasectomy pain syndrome.

Vasectomy is done by a family physician at the family planning clinic of le Centre Hospitalier de l'Université Laval. The technique used combines an occlusion with metal clips and an excision of one to two centimetres of the vas deferens. The post-operative complications encountered with 304 vasectomies were hematomas (4%), infections of the scotal skin (1%), orchi-epididymitis (1%) and granulomas (1%). All these problems were treated on an out-patient basis, and no consultation with specialists was required. Of 151 patients who came back for a post-vasectomy semen examination, one had a test result showing motile spermatozoa. These figures are comparable to other results published. The family physician can easily incorporate this simple and safe procedure into his practice.
