1. Strictly implement aseptic techniques and disinfection systems to prevent hospital-borne infections. Once a urinary catheter is contaminated or removed, it must not be reused.
2. When inserting and pulling out the urinary catheter, the movements should be light, slow and steady, and do not use excessive force to avoid damaging the urethral mucosa.
3. For patients with highly inflated bladders and extremely weak bodies, the first catheterization volume should not exceed 1000ml to prevent large amounts of urine from urinating, resulting in a sudden decrease in intra-abdominal pressure and a large amount of blood remaining in the abdominal blood vessels. It can cause blood pressure to drop and cause collapse. It can also cause sudden decompression of the bladder, leading to rapid congestion of the bladder mucosa, causing hematuria.
4. When indwelling urinary catheterization, the fixation of the urinary catheter should be checked frequently to see if it has prolapsed. If necessary, the bladder should be flushed with sterile liquid once a day; the urinary catheter should be replaced every 5-7 days. The urethra should be allowed to relax for several hours before reinsertion.

Purpose of post-operative catheterization
1. Directly extract uncontaminated urine specimens from the bladder for bacterial culture and measurement of bladder capacity, Pressure and check residual urine volume to identify urinary obstruction and urinary retention to aid diagnosis.
2. Release urine for patients with urinary retention to relieve pain.
3. Before pelvic organ surgery, the patient should be catheterized to empty the bladder to avoid accidental injury during the surgery.
4. When coma, urinary incontinence or perineal injury occurs, keep the urinary catheter to keep the area dry and clean. After surgery for certain urinary system diseases, indwelling urinary catheterization is often required to restore bladder function and heal incisions.
5. Rescue shock or critically ill patients and correctly record urine output and specific gravity to observe kidney function.
Methods to prevent urinary tract infection after catheterization after surgery
1. Fix the urinary catheter properly, avoid bending and bending, ensure that the height of the urine collection bag is lower than the level of the bladder, avoid contact with the ground, and prevent Retrograde infection.
2. Keep the urine drainage device closed, smooth and complete, and clamp the drainage tube during activities or transportation to prevent urine from flowing back.
3. A personal collection container should be used to empty the urine collection bag promptly. When emptying the urine collection bag, follow the principles of aseptic operation and avoid the outlet of the urine collection bag from touching the collection container.
