What should I do if I have difficulty urinating after a colonoscopy?

Generally, difficulty urinating after a colonoscopy may be caused by bowel preparation, pressure from the endoscope, or tension in the urinary sphincter. This can be managed through methods such as drinking more water, pelvic floor muscle exercises, medication, bladder area massage, and heat application. Specific analysis is as follows:

1. Drink More Water

Prior to a colonoscopy, bowel preparation is required, including bowel cleansing and fasting. These procedures may lead to dehydration and concentrated urine, resulting in difficulty urinating. It is recommended that patients drink plenty of water to maintain adequate hydration, which helps alleviate urinary difficulties. Additionally, avoid straining during urination, and try to relax the body and reduce anxiety.

2. Pelvic Floor Muscle Exercises

During colonoscopy, the anus and rectum are subjected to pressure from the scope, which may affect pelvic nerve conduction and cause urinary sphincter tension, leading to difficulty urinating. Patients are advised to perform pelvic floor muscle training under medical guidance. Strengthening the contraction and relaxation ability of the pelvic floor muscles through exercise can help relieve urinary difficulties.

3. Medication

Colonoscopy may cause patients to feel nervous or anxious, and these emotions may interfere with pelvic nerve conduction, resulting in urinary sphincter tension and difficulty urinating. Under medical supervision, patients may use medications such as tamsulosin hydrochloride sustained-release capsules or finasteride tablets to reduce urethral resistance.

4. Bladder Area Massage

Gently massaging the bladder area may stimulate the bladder muscles and promote urine expulsion. Use fingertips to softly massage the bladder region in a clockwise direction.

5. Heat Application

A hot water bottle or warm towel can be gently applied to the bladder area, which may help relax the urethra and bladder muscles and facilitate urination.

If symptoms persist, prompt medical attention is recommended to prevent delayed treatment and potentially serious complications.
