Depth and method of catheterization in men

Nowadays, with the changes in the environment and people's emphasis on health, going to the hospital for physical examination or hospitalization has become commonplace. This is because people's health awareness has improved, and they know that fighting the disease will only make it more painful. Therefore, during the examination and treatment process in the hospital, inserting a catheter is definitely a painful thing. So why do we need to do this catheterization? What is the depth of this tube? Let's learn about it below.

Methods of catheterization:

1. The patient lies on his back with his legs bent and outstretched, and a tarpaulin or a middle sheet placed under his buttocks. The patient should first wash the vulva with soapy water; male patients should turn back the foreskin for washing.

2. Use 2% mercurochrome, 0.1% gentamicin or 0.1% chlorhexidine solution to disinfect the urethral opening and vulva in a circular pattern from the inside out. Then cover the vulva with a sterile drape. For men, wrap the penis with a sterile drape to expose the urethral opening.

3. The operator wears sterile gloves and stands on the right side of the patient. He holds the penis with the thumb and index finger of his left hand. For females, he spreads the labia minora to expose the urethral opening. With his right hand, he slowly inserts the catheter coated with sterile lubricant into the urethra. The outer end of the catheter is clamped with a hemostatic forceps, and its opening is placed in a sterile curved plate. The catheter is inserted about 15-20cm for males and 6-8cm for females. The hemostatic forceps are released and urine can flow out.

4. If bacterial culture is required, collect midstream urine in a sterile test tube for testing.

5. After the operation, clamp the catheter and then slowly pull it out to prevent urine from leaking out and contaminating clothes. If indwelling catheterization is required, fix the catheter with tape to prevent it from coming out, clamp the outer end with hemostatic forceps, and wrap the tube mouth with sterile gauze to prevent urine from escaping and contamination; or connect a sterile plastic bag for urine retention and hang it on the side of the bed.

Purpose of catheterization :

1. Draw uncontaminated urine specimens directly from the bladder for bacterial culture, measure bladder capacity and pressure, check residual urine volume, and identify urinary retention and urine retention to assist in diagnosis.

2. Help patients with urinary retention to release urine to relieve pain.

3. Before pelvic organ surgery, the patient should be catheterized to empty the bladder to avoid accidental injury during the operation.

4. In case of coma, urinary incontinence or perineal injury, retain the catheter to keep the area dry and clean. After surgery for certain urinary system diseases, indwelling catheterization is often required to promote the recovery of bladder function and the healing of incisions.

5. When rescuing patients in shock or critical condition, accurately record urine volume and specific gravity to observe kidney function.
