Laparoscopic treatment of a huge seminal vesicle calculus: A case report and review of literature

A 67-year-old male patient had a history of repeated urinary tract infections for numerous years. X-ray examination revealed a large calcific density in the pelvic cavity, with a diameter of 10.4 cm and a CT value of ~792.9 HU. On MRI of the pelvis, the lesion displayed with extremely low signals. The inside of the stone had a concentric ring shape with a slightly higher signal and the patient was diagnosed with a large left seminal vesicle calculus. Laparoscopic surgery was selected to treat the stone. The patient recovered rapidly and the symptoms, including urgency, urinary frequency, as well as lower abdominal and perineal pain, were obviously improved. The present case study reports on the largest seminal vesicle calculus reported in the current English literature in addition to a brief literature review. Cases of seminal vesicle calculi (SVC) are rare. The present study reports on a case of SVC, which is the largest reported in current English literature, to the best of our knowledge.
