Introduction: The authors present the first case of a patient with single cystic seminal vesicle accompanied by left kidney agenesis, referring for diagnosis and treatment.
Material and methods: This is the case of a 22-year-old patient presented for chronic pelvic pain.
Investigations: abdominal and transrectal ultrasound as well as the computer tomography showed a cystic pelvic tumor with a diameter of around 8.5/6 cm, and left kidney agenesis. The treatment for this condition varies from watchful waiting for asymptomatic cysts, to excision. We performed a plasty of the unique seminal vesicle.
Results: The postoperative evolution was uneventful with pain remission and improvement of ejaculatory function.
Conclusions: Single seminal vesicle has a very low incidence. For this pathology, partial vesiculectomy represents a viable therapeutic option in order to preserve sexual function in the case of a young patient.
