Clean Intermittent Catheterization: An Effective Method for Bladder Management

1. What is Clean Intermittent Catheterization (CIC)?

Clean intermittent catheterization (CIC) is a procedure in which a catheter is inserted into the bladder through the urethra at regular intervals under clean conditions, allowing the bladder to be emptied and then removing the catheter. This method helps patients manage their bladder effectively, prevents urinary retention, and reduces the risk of urinary tract infections and other related complications.

2. Who is Suitable for Clean Intermittent Catheterization (CIC)?

Patients with neurogenic bladder, including those with spinal cord injury, multiple sclerosis, Parkinson’s disease, or other conditions causing bladder dysfunction that prevents voluntary urination.

Patients requiring temporary bladder emptying for procedures such as surgery or childbirth.

Patients with urinary tract infections or stones. These patients need frequent bladder emptying to relieve symptoms, making intermittent catheterization appropriate.

Important considerations:
CIC is not suitable for all patients who cannot urinate voluntarily. For example, patients without urinary retention—especially elderly males—do not require intermittent catheterization.

Patients with urethral anatomical abnormalities, active urinary tract infection, severe heart, liver, or kidney disease, or bleeding disorders are also not suitable candidates for CIC.

3. How Often Should Clean Intermittent Catheterization (CIC) Be Performed?

The interval between catheterizations depends on the post-void residual urine (PVR), generally every 4–6 hours. Using urodynamic studies to determine the bladder’s maximum safe capacity, each catheterization should ideally drain less than this volume.

For example, if the maximum safe bladder capacity is 400 mL, catheterization should initially be performed every 4–6 hours, no more than six times per day, with each session draining less than 400 mL.

If the patient can void partially on their own, the interval between catheterizations can be adjusted based on residual urine volume:

• PVR > 200 mL: catheterize 4 times daily
• PVR > 150 mL: catheterize 3 times daily
• PVR > 100 mL: catheterize 2 times daily
• PVR < 100 mL: catheterize once daily

PVR 50–80 mL or less (or if residual volume is negligible relative to bladder capacity): CIC can be discontinued.

4. What Are the Advantages of Clean Intermittent Catheterization (CIC)?

Reduces the risk of infection: CIC can lower the complications associated with long-term indwelling catheters, such as urinary tract infections, hydronephrosis, and even renal failure.

Decreases bladder pressure: By emptying the bladder promptly after each catheterization, CIC prevents overdistension, promotes timely recovery of bladder blood flow, and enhances resistance to infection.

Promotes bladder function recovery: CIC can facilitate early restoration of detrusor reflexes, prevent bladder contracture, and support overall recovery of bladder function.

Relieves patient discomfort: Indwelling catheters require long-term use of urine collection bags, which can interfere with rehabilitation, daily life, and cause psychological distress. CIC allows patients to perform catheterization themselves, reducing discomfort and improving quality of life.

5. Why Should Patients Performing Intermittent Catheterization Follow a Fluid Intake Plan?

The purpose of a fluid intake plan is to regulate urine production and excretion, preventing bladder overdistension and protecting kidney function. By drinking fluids regularly, patients can maintain adequate urine volume and voiding frequency, which helps reduce post-void residual urine, prevent urinary tract infections, and avoid hydronephrosis.

Important considerations: The above fluid intake plan is not suitable for all patients. For example, patients with severe cardiovascular disease, renal insufficiency, or urinary tract obstruction require careful planning and adjustment of fluid intake.

6. What Should Be Noted During Clean Intermittent Catheterization (CIC)?

1.Hand and catheter hygiene: Wash hands and clean the catheter before insertion to reduce the risk of bacterial infection.

2.Lubrication: Use liquid paraffin or another appropriate lubricant to fully coat the catheter, avoiding urethral mucosal injury.

3.Catheter type: Single-use catheters are recommended. If reuse is necessary, clean the catheter and store it in a cool, dry place.

4.Timing: If the patient has normal bladder sensation, catheterize promptly. If bladder sensation is impaired, adjust the catheterization interval based on bladder volume, typically draining about 300 mL per session.

5.Fluid intake: 1–2 days before catheterization, patients should follow a planned fluid intake schedule, maintaining balanced hydration over 24 hours, with a daily intake of 1,500–2,000 mL.

6.Avoid delaying catheterization: Do not wait until the patient feels urgent to void, as this may damage the urethra and bladder.

7.Obstruction during insertion: If resistance is encountered, pause for 5–10 seconds and withdraw the catheter 3 cm, then reinsert slowly.

8.Resistance during removal: If resistance is felt while withdrawing the catheter, it may be due to urethral spasm. Wait 5–10 minutes before attempting removal again.

9.Patient discomfort: If the patient experiences discomfort or pain during catheterization, notify a physician or nurse immediately to adjust the technique or medication as needed.

Conclusion: Clean intermittent catheterization is an effective method for bladder management and is the preferred approach for patients with neurogenic bladder. It helps patients better control urine output, prevents urinary tract infections, and reduces the risk of other related complications.
