Intermittent Catheterization — the "Gold Standard" for Managing Neurogenic Bladder Dysfunction in Spinal Cord Injury Patients

2025-09-03

1. Introduction

Neurogenic bladder refers to bladder dysfunction caused by neurological lesions that affect bladder control. In patients with spinal cord injury, neurogenic bladder primarily manifests as lower urinary tract dysfunction. Storage-phase dysfunction is characterized by urinary urgency, urge incontinence, increased urinary frequency, and nocturia. Voiding-phase dysfunction includes intermittent or weak urinary stream, difficulty initiating urination, and dribbling. Additionally, patients may experience incomplete bladder emptying, recurrent urinary tract infections, vesicoureteral reflux, and increased risk of upper urinary tract damage, which can lead to long-term complications such as hydronephrosis and renal impairment. Effective bladder management, therefore, is critical to preserving renal function and improving quality of life.

2. Definition

Clean Intermittent Catheterization (CIC) is a therapeutic method in which the patient or caregiver periodically inserts a catheter into the bladder under clean conditions to drain urine. In 1947, Guttmann introduced Sterile Intermittent Catheterization (SIC), and in 1971, Lapides et al. proposed Clean Intermittent Catheterization (CIC), also introducing Clean Intermittent Self-Catheterization (CISC) for the management of neurogenic bladder. The primary goals are to empty the bladder regularly, reduce post-void residual urine, and protect upper urinary tract function, including the kidneys and ureters. CIC has since become the preferred standard of care for patients with neurogenic bladder due to its demonstrated benefits in reducing urinary tract infections, preventing bladder overdistension, minimizing vesicoureteral reflux, and improving long-term renal outcomes. Moreover, it enhances patient independence and quality of life by enabling safe self-management of bladder emptying.

3. Why CIC is the “Gold Standard”

3.1. American Urological Association (AUA):
“CIC is the preferred method for managing neurogenic bladder and can significantly reduce the risk of upper urinary tract damage.” (AUA Guidelines 2022)

3.2. European Association of Urology (EAU):
“CIC should be the first-line treatment for patients with spinal cord injury, superior to indwelling catheterization.” (EAU Neuro-Urology Guidelines 2023)

3.3. International Continence Society (ICS) Consensus:
CIC is classified as Level 1A evidence (highest grade) and is considered the safest long-term method for managing neurogenic bladder.

3.4. Supported by Clinical Data – Safer in the Long Term
3.4.1. Reduced Infection Rate: Compared with long-term indwelling catheters, CIC patients have over a 60% lower risk of severe urinary tract infections (Groen et al., 2018).
3.4.2. Renal Protection: In a 20-year follow-up, only 5% of patients practicing CIC developed hydronephrosis, compared to 35% in the indwelling catheter group (Weld et al., 2012).

4. Improved Quality of Life

4.1. Bladder Protection: Regular bladder emptying helps maintain a low-pressure storage environment, preserving bladder function and reducing the risk of upper urinary tract damage.
4.2. Greater Autonomy: Performing catheterization 4–6 times daily allows patients to remain independent and freely engage in daily activities during the rest of the day.
4.3. Privacy and Dignity: No need for external urine bags, enabling social participation without stigma or limitations.
4.4. Lower Costs: Reduces hospitalizations and medical expenses associated with recurrent urinary tract infections.
4.5. Enhanced Comfort and Confidence: Hydrophilic catheters provide smooth, low-friction insertion, minimizing discomfort and anxiety, and encouraging adherence to long-term bladder management.
4.6. Better Overall Well-being: Consistent, safe bladder management supports both physical health and psychological well-being, allowing patients to maintain a more active and fulfilling lifestyle.

5. Features of Daxan Hydrophilic Coated Intermittent Catheters

5.1. Advanced Hydrophilic Coating: Strong adhesion, uniform distribution, and excellent low-friction performance. Daxan is the only company in China’s biomedical coating field during the 13th Five-Year Plan to receive national key R&D program support as the leading unit.
5.2. Smooth, Safe Perforations: The catheter body uses a thermal fusion perforation method, creating smooth, rounded holes that minimize urethral mucosa damage, reduce bleeding and infection risk, and facilitate ease of operation.
5.3. Soft and Protective: The catheter is soft and enhanced with lubricating coating, providing gentle protection to the urethra and preventing injury.
5.4. Anti-Injury Design: Bullet-shaped tip with smoothly rounded perforations ensures safe insertion.
5.5. Instant Slipperiness: Activates immediately upon contact with water, lowering the risk of contamination. The coating remains effective for a prolonged time after activation, allowing sufficient operational time for the user.
5.6. Patient-Centered Use: Designed for ease of handling, minimal discomfort, and safe long-term self-catheterization, supporting independence, dignity, and improved quality of life.
