چکیده مقاله:

Background: Vasectomy (Closing or removing a portion of the vas deferens) is the most common method of contraception in men. Approximately 42 to 60 million men around the world are undergoing vasectomy. According to a study performed in Iran in 2006, prevalence of vasectomy in Iranian men is 3%. Possible side effects of vasectomy include: inflammatory reactions, thickening and inflammation of the prostate epididymis, sperm granuloma, formation and thickening and enlargement of the epididymis and the resistant pain of testis. In addition, this study is the first study to examine the microscopic surgical vasovasostomy in Iran, so we can determine the environmental factors. Methods: The records of all cases of vasovasostomy performed in Rasool Akram, from January 2014 to January 2015 were extracted. We reviwed all items of the check list from their records and follow the patients after surgery. Factors affecting surgical success, after entering the questionnaires, were analyzed using SPSS and the results were presented.Result: The success rate of surgery was 31 patients (62%). The relationship between the study variables was measured by univariate and multivariate analysis. Duration of the vasectomy surgery successfully had a significant inverse relationship with vasovasostomy results(OR=0.75,P-VALUE=.001). Age of the patients was significantly correlated with success rate of the vasovasostomy surgery(OR:0.81,PVALUE=0.005). In evaluating the effect of smoking on success rate of the surgery, both age and duration of vasectomy were known as confounding factors. (OR:0.11,P-VALUE=0.01). By logistic regression analysis, significant correlation was found between smoking and success. Inguinal surgery and complications after discharge were also factors that proved to be inversely correlated with success.Conclusion: The revers relationship of different factors such as age, smoking, history of inguinal surgery, complications after discharge and the time past of vasectomy surgery with success rate of microscopic surgical vasovasostomy was confirmed. for example, patients who smoke had 89 percent higher infertility risk than those who do not smoke. Despite these factors examined in this study,it seems to be other factors not mentioned such as surgery technique and surgeon experience, and etc. that can affect the success rate of surgery. Further studies with larger sample size to evaluate the factors affecting vasovasostomy surgery are recommended.
