Ectopic ureter draining into seminal vesicle cyst is very rare congenital anomaly, which is thought to be caused by ectopic ureteral bud arising on the mesonephric duct. It is often associated with ipsilateral renal agenesis. We experienced a case of ectopic ureter draining into seminal vesicle cyst that is associated with ipsilateral renal agenesis. Generally, an invasive modality, that is, cyst puncture, cystography, or seminal vesiculography, is essential in the confirmative diagnosis of ectopic ureter. However, we could establish a definitive diagnosis with magnetic resonance imaging.
异位输尿管引流至精囊囊肿是一种非常罕见的先天性异常，被认为是由中肾管上的异位输尿管芽引起的。它常与同侧肾缺如相关。我们遇到了一例异位输尿管引流至精囊囊肿且伴有同侧肾缺如的病例。一般来说，侵入性检查方法，即囊肿穿刺、膀胱造影或精囊造影，对于异位输尿管的确诊至关重要。然而，我们通过磁共振成像建立了明确的诊断。
