Urinary tube clamping training helps rectal cancer patients recover from urination after surgery

After radical surgery for rectal cancer, the urination function of patients is often not restored as quickly as after appendectomy. This is because radical surgery for rectal cancer requires complete removal of the mesorectum, and the pelvic plexus nerves that control the urination function will be damaged to some extent during the pelvic freeing process. If the catheter is removed immediately after surgery, patients often cannot urinate or urinate incompletely.

Therefore, rectal cancer patients are routinely required to undergo urinary tube clamping training 3 to 5 days after radical surgery. In order not to affect sleep, this training is generally performed during the day. During training, the urinary tube is clamped with a clamp every 2 to 3 hours, and then the urinary tube is opened for 20 to 30 minutes. After 1 to 2 weeks of training, the patient can generally feel the urge to urinate, indicating that the sensory nerves of the urination function have begun to recover. If the urge to urinate is obvious, it means that the sensory nerves of the urination function have basically recovered. Since the sensory nerves and motor nerves of the urination function are intertwined, the motor nerves will recover after the sensory nerves recover. At this time, the urinary tube can be pulled out and the patient can urinate on his own.

Generally speaking, the normal amount of urine for a normal person is more than 200 ml to 300 ml. If the patient can urinate 200 ml to 300 ml of urine after removing the urinary tube, it means that the urination function has basically recovered. If the patient cannot urinate or the amount of urine is too small, it means that the urination function has not recovered. At this time, it can also be determined by B-ultrasound detection of residual urine in the bladder after urination. If it exceeds 50 ml, it means that the urination function has not recovered. At this time, the urinary tube should continue to be indwelling, and training should continue.

The urinary catheter should be replaced every 2 weeks. Generally, the patient will recover urination function in about 1 month, but a few patients may take 3 to 6 months to finally recover.
