What is the order of disinfection of male urethral opening?

Some men suffer from certain men's diseases, which can lead to the inability to urinate normally, which can cause great harm. To address this problem, catheterization can be used clinically to help patients urinate. During the catheterization process, a catheter must be inserted into the bladder. This process can easily cause infection, so the urethral opening must be disinfected during catheterization. The correct disinfection order is as follows.

Male urethral disinfection sequence:

Generally, the urethra and penis are disinfected first.

Guidance:

Finally, expand the scope to the scrotum and perineum.

Generally disinfection is required 3 times.

Then insert the catheter, paying attention to the depth of the catheter, which is usually inserted to the bottom.

Version 1:

One-time disinfection: from outside to inside, from top to bottom

Disinfect the mons pubis, penis, and scrotum → expose the urethral opening → disinfect the urethral opening, glans penis, and coronal sulcus

Secondary disinfection:

Expose the urethral opening with your left hand and fix it → Disinfect the urethral opening, glans penis and coronal sulcus again

Version 2:

One-time disinfection: from inside to outside, from top to bottom

Male: Disinfect from inside to outside, urethral opening → vulva

Female: Spread the labia majora from inside to outside and from top to bottom

Secondary disinfection:

Expose the urethra and disinfect the urethra and vulva again

Version 3:

One-time disinfection:

Male: mons pubis, penis, scrotum → expose the urethral opening → disinfect the urethral opening, glans penis, and coronal sulcus

Female: Disinfect the mons pubis and labia majora, then separate the labia majora and disinfect the labia minora from outside to inside and from top to bottom → urethral opening.

Secondary disinfection:

Expose the urethral opening and fix it → Disinfect the urethral opening, glans penis and coronal sulcus again

There are many versions, and the order of disinfection varies. The controversy is centered on the order of "one disinfection"?

Here are a few versions for you to discuss:

1. Where did the disinfection sequence for catheterization first come from? Are there any guidelines or specifications?

2. What is the order of catheterization disinfection?

Generally, the urethra and penis are disinfected first. Guidance: Finally, the scope is expanded to the scrotum and perineum. Generally, disinfection is required 3 times. Then insert the catheter, pay attention to the depth of the catheter, and generally insert it to the bottom.

Sexual catheterization requires a sequence and strict disinfection. The general sequence is to disinfect the urethral opening and penis first, then expand the scope to the scrotum and perineum, and disinfect repeatedly three times before inserting the catheter. Pay attention to the depth of the catheter, which is usually inserted to the bottom. Insert the catheter gently to avoid damaging the urethral mucosa. If there is a sense of obstruction during insertion, change the direction.
