Radical Surgical Treatment of A Large Seminal Vesicle Cyst Causing Acute Urinary Retention in A Patient with Zinner Syndrome: A Case Report and Review of Literature

Herein, we report a case of a large and complex seminal vesicle cyst causing urinary retention in a young patient with left renal agenesis, psychotic disorder, and deep venous thrombosis. Abdominal computed tomography showed left renal agenesis with associated incipient hydronephrosis of the right renal unit. Furthermore, the whole pelvis was occupied by a large, heterodense cyst (116x113x107 mm), with several adherent and small cystic lesions (39x70 mm), compressing the posterior bladder wall. Open surgical approach was performed, including bilateral vesiculectomy with resection of the vas deferentia, since these structures were closely adhering to the cystic wall, and there was no clear surgical plane between them. A brief review of the literature on the main surgical options and postoperative outcomes was also undertaken.
