Painful urination and hematuria in the naked eye after catheter removal is not necessary to be nervous, it is a normal phenomenon. Because of the long-term stimulation of the urinary catheter and the slight damage to the urethra and bladder mucosa when the catheter is removed, there will be local muscle spasm and manifest as painful urination and a small amount of bleeding due to local mucosal damage. Therefore, after catheter removal, we should pay attention to drink more water and urinate more than 2000ml per day, and the symptoms will gradually decrease to disappear after 2-3 days. If the amount of bleeding is large and the duration of bleeding is long after the catheter is removed, you can go to the hospital again for further consultation to clarify the diagnosis.
