摘　　要：Patients with congenital unilateral absence of the vas deferens(CUAVD)manifest diverse symptoms from normospermia to azoospermia.Treatment for CUAVD patients with obstructive azoospermia(OA)is complicated,and there is a lack of relevant reports.In this study,we describe the clinical features and evaluate the treatments and outcomes of CUAVD patients with OA.From December 2015 to December 2020,33 patients were diagnosed as CUAVD with OA in Shanghai General Hospital(Shanghai,China).Patient information,ultrasound findings,semen analysis,hormone profiles,and treatment information were collected,and the clinical outcomes were evaluated.Of 33 patients,29 patients were retrospectively analyzed.Vasoepididymostomy(VE)or cross VE was performed in 12 patients,the patency rate was 41.7%(5/12),and natural pregnancy was achieved in one of the patients.The other 17 patients underwent testicular sperm extraction as the distal vas deferens(contralateral side)was obstructed.These findings showed that VE or cross VE remains an alternative treatment for CUAVD patients with OA,even with a relatively low rate of patency and natural pregnancy.
