Women with a stinging sensation when urinating are advised to go to the hospital for relevant examinations to clarify the possible causes: First, acute urethritis or cystitis can cause a stinging sensation when urinating, often due to inflammation leading to an acute inflammatory reaction of the mucosa, resulting in mucosal erosion, congestion, etc., when the urine stimulates the relevant mucosa can cause a stinging sensation, requiring urine laboratory tests to clarify. Secondly, urethral stones or bladder stones can cause painful sensation when the stones flow with urine and irritate the mucous membrane during urination, and even the stones can stay in the urethra causing continuous stabbing pain in the urethra, accompanied by straining to urinate and bifurcation of urination. In addition to stabbing pain, bladder stones may also be accompanied by interruption of urination, which requires ultrasound examination of the urinary system to further rule out. Thirdly, polyps, tumors or urethral caruncles in the urethra can cause localized stabbing pain, especially when urinating, so urethroscopy or cystoscopy should be performed to clarify.
