How to restore bladder urination function after rectal cancer surgery

After rectal cancer surgery, patients often experience bladder loss of urination function. At this time, the muscles that control the bladder urination function will be damaged to a certain extent, resulting in difficulty in urination. When this happens, corresponding training must be carried out in time 3 to 5 days after the operation. Through good training, the functional pathway of urination can generally be improved to a certain extent.

How to restore bladder urination function after rectal cancer surgery

1. 3-5 days after rectal cancer surgery, urinary tube clamping training is routinely required. But everyone has to sleep at night, so the patient's urinary tube is left open without any training. During the day, clamp the urinary tube every 2-3 hours and open the urinary tube for 20-30 minutes. During 1-2 weeks of such training, the patient will generally feel the urge to urinate, indicating that the sensory nerves for urination have begun to recover. If there is a clear urge to urinate, it means that the sensory nerves for urination have basically recovered. The sensory nerves and motor nerves of urination function are intertwined. When the sensory nerves are restored, the motor nerves will be restored accordingly. At this time, the urinary tube is removed and the patient is allowed to urinate on his own.

2. A normal person usually urinates more than 200-300 ml. If the patient can urinate 200-300 ml after the urinary tube is removed, it means that the urination function has basically recovered. If you cannot urinate or only urinate a little, it means that the urination function has not recovered. If the residual urine in the bladder measured by B-ultrasound after urination exceeds 50 ml, it also means that the urination function has not recovered. If your urination function does not recover as expected, do not panic or be impatient. Insert a urinary tube immediately. If not, too much urine in the bladder will swell and damage the bladder. Continue training after inserting the urinary tube. The urinary catheter should be replaced every 2 weeks. Generally, the urination function can be restored in about 1 month. Occasionally, the patient will finally recover 3-6 months after the operation.

3. During the clamping training, it is best for the patient to drink a thermos of water every day to prevent turbid urine in the urinary tube. During this period, you can also take one tablet of Harle orally every night before going to bed, which will help with urination.

After radical surgery for rectal cancer, urination function often does not recover as quickly as after appendectomy or cholecystectomy. This is because radical resection of rectal cancer requires complete resection of the mesorectum. During the pelvic mobilization process, there will be a certain degree of damage to the pelvic plexus nerves that control the urination function. Therefore, the catheter is removed immediately after the operation, and the patient often cannot urinate or urinates incompletely.
