Abstract: A 67-year-old male patient was referred to our hospital by the community health service center for "sudden dysuria for half a day". The diagnosis of solitary fibrous tumor of the prostate was established after transrectal prostate biopsy. After excluding contraindications, laparoscopic radical prostatectomy with bladder neck urethrostomy was performed. The operation was completed in 3 h and 15 min with an intraoperative blood loss of about 100 mL. Postoperative examination of the resected tumor revealed a large spherical tumor mass measuring about 11 cm ×7.5 cm ×6 cm with a net weight of 223 g. Postoperative pathology suggested solitary fibrous tumor of the prostate (medium-risk type). The abdominal drainage tube was removed 5 days after the operation and the catheter was removed 1 week after operation. The patient had good urine control at night without incontinence but with occasional urine leakage during daytime, and the overall therapeutic effect was satisfactory. Postoperative follow-up found good urine control of the patient without signs of tumor recurrence or metastasis. Laparoscopic radical prostatectomy often is difficult for large prostate tumors with a weight exceeding 200 g, and requires the surgeon to have rich experience in laparoscopic surgery with good understanding of prostate anatomy and close cooperation of the operation team to achieve satisfactory oncology control and functional protection of the urinary system.
