Does it hurt for a man to have a urinary catheter inserted?

We all know that when performing surgery, a catheter is required to prevent urinary incontinence during and after the operation, and to avoid unnecessary trouble. Due to the unique physiological structure of men, catheterization may be more complicated than that of women. Some male patients will feel particularly painful and uncomfortable after catheterization. So, what should men pay attention to after catheterization?

1. Strictly follow aseptic operation to prevent urinary tract infection.

2. Insert the catheter gently to avoid damaging the urethral mucosa. If there is a sense of obstruction during insertion (do not insert it roughly), change the direction (or withdraw 2-3cm slightly, pour wax oil into the catheter to lubricate the urethra), and insert it again 2cm when urine flows out. Do not insert it too deep or too shallow, and avoid pulling the catheter repeatedly. (Although the guide wire can be inserted quickly and forcefully, it is most likely to damage the urethral mucosa, so it can be pulled out first; wax oil must be repeatedly applied to the entire catheter twice)

3. The size of the urinary catheter should be appropriate. For children or those with suspected urethral stenosis, the catheter should be thin.

4. For those with an overfull bladder, urination should be slow to avoid sudden decompression that may cause bleeding or fainting.

For patients with highly distended bladders and extreme weakness, the first catheterization volume should not exceed 1000ml to prevent large amounts of urination, which may lead to a sudden decrease in intra-abdominal pressure and a large amount of blood retained in the abdominal blood vessels, causing a drop in blood pressure and prolapse. The sudden decompression of the bladder may also cause rapid congestion of the bladder mucosa and cause hematuria.

5. When measuring residual urine, instruct the patient to urinate on his own first, and then catheterize. The residual urine volume is generally 5-10ml. If it exceeds 100ml, catheterization should be left in place.

6. When indwelling catheterization is in place, the fixation of the catheter should be checked frequently to see if it has come out. If necessary, the bladder should be flushed with sterile liquid once a day. The catheter should be replaced every 5-7 days, and the urethra should be relaxed for several hours before reinsertion.

7. The catheterization speed should not be too fast for patients with overfilled bladder, otherwise shock or bladder bleeding may occur. Urine should be released slowly in several times, about 150-200ml each time, repeatedly to gradually empty the bladder.
