Minimally Invasive Management of Zinner's Syndrome with Same-Session Robot-Assisted Seminal Vesiculectomy and Ipsilateral Nephroureterectomy Using a Single Geometry of Trocars

Abstract Background: Seminal vesicle cyst is an extremely rare condition, which is frequently congenital and associated with Zinner's syndrome. This syndrome represents a constellation of seminal vesicle cyst, ipsilateral or contralateral renal agenesis or renal dysplasia, ureteral ectopia, and ejaculatory duct obstruction. We report a young symptomatic patient undergoing robot-assisted laparoscopic excision of a huge seminal vesicle cyst during which an atrophic ipsilateral kidney was discovered incidentally and managed by nephroureterectomy in the same session without changing trocar positions. Case Presentation: A 23-year-old male patient presented with a 2-year history of lower urinary tract symptoms, perineal pain, and recurrent urinary tract infections. Ultrasonography revealed the absence of left kidney and a fluid-filled cystic lesion located behind the bladder on the left side, which was consistent with cystic dilatation of the left seminal vesicle. MRI confirmed the diagnosis of a huge cystic st...
