There is blood in the urine, so we need to go to the urology department for clinical diagnosis through physical examination, routine urine test, color ultrasound of the urinary system, and intravenous urography. The patient needs to pay attention to the following points: First, benign prostatic hyperplasia leads to gross hematuria. Use drugs to relieve urethral resistance regularly, and perform minimally invasive surgery when necessary. Second, patients with urinary calculi need to choose drug lithotripsy, extracorporeal shock wave lithotripsy or surgical treatment according to the size of the stone. Third, most patients with bladder tumor choose transurethral resection of bladder tumor or laparoscopic surgery.
