Pain when urinating is recommended to go to the hospital for further examination to clarify the cause. There may be: 1. When acute urethritis and cystitis occur, pain during urination can occur. Due to bacterial infection, the mucosa of the urethra becomes congested and edematous, or there is a local microscopic injury, when urine will stimulate the local area and produce a more obvious pain. At the same time, there will be an increase in the frequency of urination or a sense of incomplete urination. 2. If there are stones in the urethra or bladder, there may be pain in the urethra during urination, accompanied by poor urination and bifurcation of urination. Urethroscopy or ultrasound examination of the urinary system is needed to rule out the presence of stone lesions; 3. The presence of polyps or tumors in the urethra may also cause pain in the urethra and may be accompanied by bleeding in the urethra. Urethroscopy is needed to rule out the presence of urethral polyps, tumors and other lesions.
