After catheter removal for urinary retention, you can exercise by urinating regularly and lifting the anus. Urinary retention is a condition in which the patient has a large amount of urine in the bladder memory and is unable to urinate on his/her own because the lower abdomen is distended, usually requiring a catheter to drain the urine. After the catheter is removed, urinary retention can be improved by regular urination and anal lifting training. 1. Regular urination: After the catheter is removed, the patient should drink more water and go to the toilet to urinate in half an hour or one hour, regardless of whether there is a desire to urinate or not. Or as long as there is a desire to urinate, go to the toilet to urinate. 2. Lift the anus training: after urinary retention catheter removal, patients can do anal lifting training, take a bent position, and then gradually lift the anus, and then gently put down. This can increase the strength of the pelvic floor muscles and the strength of the bladder forced urinary muscle, improve urinary function. Urinary retention catheter extraction should try to drink more water to increase urine volume, avoid holding urine. At the same time pay attention to hygiene, prevent urinary infection.
