PURPOSE: We determined the feasibility and outcome of microsurgical reconstruction of the excurrent ductal tract in men with obstruction secondary to iatrogenic injury to the epididymis from hydrocelectomy. MATERIALS AND METHODS: A retrospective chart review was done to identify men with iatrogenic injury to the epididymis or scrotal vas deferens and a history of hydrocelectomy. The outcome of microsurgical reconstruction was assessed by postoperative semen analysis. Pregnancy data were noted in patients actively attempting to conceive at a followup of 6 months or greater. RESULTS: Eight men were found to have iatrogenic injury to the epididymides (6) or scrotal vas deferens (2) due to previous hydrocelectomy. Injury was bilateral in 4 men and unilateral in 4 with contralateral testicular absence, dysfunction or obstruction resulting from different etiologies, rendering all patients azoospermic. The mean obstructive interval was 16 years (range 6 to 32). Bilateral and unilateral vasoepididymostomy was performed in 4 and 2 men each, and crossed vasovasostomy was performed in 2. Postoperative semen analysis data were available on 6 men. A patent microsurgical anastomosis was observed in 5 of 6 cases (83%). Four of the 5 men with patency had a followup of greater than 6 months, of whom 3 actively pursued conception. One pregnancy was achieved naturally and 1 was achieved by in vitro fertilization with intracytoplasmic sperm injection. CONCLUSIONS: Hydrocelectomy may result in inadvertent injury to the excurrent ductal tract, causing obstruction and infertility. Microsurgical reconstruction results in the restoration of spermatozoa to the ejaculate in 83% of cases. The return of spermatozoa to the ejaculate may provide the couple with an opportunity to conceive naturally or through assisted reproduction.
