A Case of Ectopic Vas Deferens With Contralateral Vesicoureteral Reflux Causing Recurrent Pyelonephritis and Epididymitis.

Ectopic vas deferens is a rare congenital anomaly and can be associated with urinary tract and genital anomalies. Therefore, patients can present with a variety of symptoms. We present the case of a four-year-old uncircumcised male patient with ectopic vas deferens and contralateral vesicoureteral reflux (VUR). Our patient had been caused breakthrough pyelonephritis and recurrent epididymitis alternately, and this made it difficult for us to reach an accurate diagnosis. The left vas deferens was connected to the bladder, and it was opening next to the left ureteral orifice. A bilateral ureteroneocystostomy and left vasectomy were performed, and the patient has been doing well and has had no further urinary tract infections (UTIs) or epididymitis.
