Bladder prostate type polyps are rare clinically, and a case was admitted to our department, which is reported below. The patient, male, 39 years old, was admitted to the hospital for 10 days due to the finding of bladder occupancy by ultrasound during physical examination. The patient had no obvious carnal hematuria, no urinary frequency, urinary urgency, urinary pain, no difficulty in urination, no chills and fever. Ultrasound showed hypoechoic changes in the right wall of the bladder, protruding into the bladder cavity, with a size of about 5×8 mm. CT showed that the right wall of the bladder was not smooth, with a possible tumor. Cystoscopy showed a polyp-like mass of about 20px in diameter in the right wall of the bladder with light red color, smooth surface, no obvious bleeding and ulceration, the rest of the bladder mucosa was intact and smooth, the opening of the ureter on both sides was clear, and the morphology and spraying of urine were normal. TURBt was performed under lumbar anesthesia, and the bladder mucosa was excised within 25 px of the mass and its surrounding area to the superficial muscular layer, and pathological examination of the specimen showed prostatic polyps of the bladder. The catheter was removed 5 days after surgery, and the patient had no meatus hematuria, and no recurrence of cystoscopy was seen at the 3-month postoperative follow-up. The average age of onset of prostatic polyps in the bladder is 60.2 years old in a group of foreign reports. The etiology of the disease is unknown. It was thought to be an ectopic prostatic tissue in the bladder, but now it is considered to be a saprophytic variant of the metastatic epithelium of the bladder. Depending on the size and location of the lesion, the clinical presentation may include hematuria, frequency and difficulty in urination, while some patients may be asymptomatic. Imaging, cystoscopy and pathological biopsy can clarify the diagnosis. As it involves the choice of treatment and estimation of prognosis, attention should be paid to differentiate it from bladder metastatic cell carcinoma. The treatment of this disease is mainly surgical and the surgical modality should be determined by the size and location of the polyp to perform TURBt or partial cystectomy. The prognosis of this disease is good and recurrence and malignancy are rare.
