Unilateral cyst of the seminal vesicle, ipsilateral ectopic ureter and ipsilateral renal agenesis are the components of a rare congenital abnormality affecting the male urogenital tract. The clinical picture is characterized by a retrovesical cystic tumor which may be asymptomatic or cause nonspecific symptoms. Differential diagnosis includes cysts of the Müllerian duct, the urogenital sinus/ejaculatory duct, and the prostate. Pelvic ultrasonography is an appropriate method of investigating patients in whom this malformation is suspected, whereas more invasive radiologic procedures are indicated in selected cases only. Treatment for retrovesical cysts should be restricted to symptomatic patients. Conservative therapy may result in subjective improvement, but surgical exploration and excision of the abnormal organs is the only definitive treatment.
精囊单侧囊肿、同侧异位输尿管和同侧肾缺如是一种影响男性泌尿生殖道的罕见先天性异常的组成部分。临床表现为膀胱后囊性肿瘤，可能无症状或引起非特异性症状。鉴别诊断包括苗勒管囊肿、泌尿生殖窦/射精管囊肿和前列腺囊肿。盆腔超声检查是对怀疑有这种畸形的患者进行检查的合适方法，而仅在特定病例中才需要更具侵入性的放射学检查。膀胱后囊肿的治疗应仅限于有症状的患者。保守治疗可能会使症状主观上有所改善，但手术探查和切除异常器官是唯一的确定性治疗方法。
