Abstract
Aim: We report a rare case of a symptomatic, inflamed giant retroperitoneal cyst. The lesion was found to represent an afunctional, sac-like upper pole of the right kidney with a dilated, duplicated collecting system and a megaureter ectopically inserted into the ipsilateral seminal vesicle, resulting in male infertility. Case report: A 26-year-old male patient presented to the emergency department with the right flank pain, nausea, and high body temperature. A giant retroperitoneal cyst was diagnosed which proved to be afunctional, sack-like upper pole of the right kidney with its dilated, separated collecting system and megaureter ectopically inserted into the ipsilateral seminal vesicle. Although the patient’s symptoms were relieved after percutaneous drainage of the cyst, the symptoms recurred one month later, and an open surgical excision was performed. The patient’s symptoms disappeared and his impaired fertility was fully recovered after surgery. Conclusion: There is a close relation between congenital anomalies of the urinary tract and the seminal vesicle cysts due to their close embryological origin which often cause concurrent malformations of the ipsilateral upper urinary tract. Cystic formations of the retroperitoneum require thorough evaluation and extensive imaging to rule out congenital urogenital malformations. Additionally, male fertility testing is required if there is any indication of genitourinary system development anomalies because early detection and treatment of anomalies can lead to a partial or full recovery of fertility.
