How to sterilize a catheter

Patients undergoing transurethral catheterization need to disinfect the perineum and the area around the urethral opening, and patients undergoing catheterization via cystocentesis need to disinfect the lower abdomen and perineal area.
Urinary catheterization is a common clinical operation method, the main purpose is to drain the urine in the bladder, usually through the urethra catheterization, some patients due to the need of the condition can also be vesicourethrocystostomy to complete urinary catheterization.
Disinfectant is generally recommended to use povidone-iodine, which is less irritating to the perineum, and it is best to wear sterile gloves and use sterile forceps and other instruments to avoid contamination.
If the patient is catheterized via the urethra, urine may be drawn through a catheter in the urethra and eventually collected in a catheterization bag. The disinfection site for these patients is mainly the perineum and around the urethral opening, and disinfect the area around the urethral opening and the urethral tube that is 3-5 cm away from the urethral opening from the outside to the inside (the catheter is the inside); female patients need to pay attention to disinfecting the area around the vaginal opening and try to avoid menstruation period.
If the patient is undergoing catheterization via cystostomy, the catheter is placed at the drainage hole in the lower abdomen, and urine flows into the catheterization bag through the catheter in the drainage hole. When sterilizing this patient, it is necessary to sterilize the 5㎝ area around the fistula and the urinary catheter that is 3-5㎝ from the skin from the inside to the outside. Avoid bacterial infection in the perineal area.
It is important to note that disinfection of patients with urinary catheterization needs to be carried out by professional physicians or nurses in order to avoid improper operation, which may lead to infections and other negative consequences.
