Patients with stinging sensation when urinating are recommended to go to the hospital for relevant examinations to clarify the possible causes. 1. Acute urethritis can cause stinging sensation when urinating and can be accompanied by an increase in urethral secretions, which is recommended to be further ruled out by urinalysis or culture of secretions. 2. Urethral stones can cause stinging sensation if the stones are obstructed in the urethra, and can be accompanied by hematuria or painful urination and bifurcation. 3. 3.Urethral tumors can also cause stinging sensation during urination, while tumors can block the urethra and cause blockage of urination, and can also cause blood dripping from the urethral orifice. 4.Urethral trauma, such as urethral contusion or catheter extraction, is recommended to further clarify the presence of tumors. Contusion or catheter removal can cause urethral stinging pain, which is mostly related to direct injury.
