THE FREQUENCY OF COEXISTED CONGENITAL BILATERAL ABSENCE OF VAS DEFERENS AND UNILATERAL KIDNEY AGENESIS IN INFERTILE MEN REFERRED TO ROYAN INSTITUTE

Abstract

Background:Congenital bilateral absence of the vas deferens (CBAVD) leads to azoospermia and infertility. It might be seen with unilateral kidney agenesis. There is no study about the prevalence of coexistence of unilateral kidney agenesis and the vas deferens anomaly of iranian. The aim of this study was to assess the frequency of coexisted CBAVD and unilateral kidney agenesis in infertile men, referred to royan institute between 2016 and 2019.Methods:A cross_ sectional study was done on eligible patients. The study was approved by the institutional ethics committee. Infertile men who had been examined by an urologist and were suspected for CBAVD, referred to ultrasound ward. Using abdominal ultrasound examination, kidney anomalies were ruled out. Data was entered into spss software 21. A value less than 0.05% was considered significant.Results:Participants aged 33.05±6.35. A total of 110 patients were eligible. In 66 patients CBAVD was detected. 23 patients had left side VD, and 21 patients had right side VD. 12 (11%) men met both CAVD and unilateral kidney agenesis. The percentage of coexisted CBAVD and unilateral kidney agenesis was 9.1%, and coexisted congenital unilateral absence of the vas deferens (CUAVD) and unilateral kidney agenesis was 1.8%. However, here was no significant difference (P=0.07).Conclusion:Kidney agenesis cannot be detected by routine laboratory tests or transrectal ultrasound examination. Hence, it should be ruled out in CAVD patients, using abdominal ultrasound examination after transrectal examination
