Usually normal urination can be resumed about 3 days after catheter removal, but there are individual differences. A urinary catheter is a tube inserted into the bladder from the urethra to drain urine. It is mainly used for urinary retention, bladder outlet obstruction, urinary incontinence, and accurate detection of urine output, etc., and it can also be used for patients who are unable or unwilling to collect urine, or are bedridden for a long period of time. If the patient removes the catheter, most of them can resume normal urination in about 3 days, but due to individual differences, some patients can also resume normal urination only 1 week after the catheter is removed. At the same time, patients also need to observe the color, amount and nature of urine, and properly fix the urinary catheter to keep the tube open, and reasonably adjust the position of the urinary catheter if there is blockage. Patients are advised to take good care of the catheter after its removal under the strict guidance of the doctor and pay close attention to their own status.
