Common Issues in Urinary Catheterization and Nursing Measures

For individuals with neurogenic bladder, intermittent catheterization is an economical and effective method. However, various challenges may arise during the procedure. This article summarizes the most common problems encountered during catheterization and provides corresponding nursing guidelines for reference.

Common Issues

1. Urethral Pain and Discomfort During Catheterization: Due to anatomical differences, the diameter of the urethra varies between individuals. Using a catheter that is too large can cause mechanical trauma to the urethra and may damage the urethral mucosa.

2. Patient Anxiety: In general, patients tend to be anxious, which can cause abdominal muscle tension and urethral spasms, making it difficult to insert the catheter. Repeated insertion attempts may further lead to localized bleeding of the urethral mucosa.

3. Insufficient Technical Skill: Inexperienced nursing staff may fail to properly navigate the physiological curvature of the urethra. Forceful insertion when resistance is encountered can cause injury. In patients with urinary retention, prolonged urinary holding leading to bladder overdistension can cause significant discomfort.

4. Incorrect Insertion Depth: Insufficient insertion depth prevents urine drainage, while inserting too deeply may injure the bladder wall.

5. Inadequate Pre-Procedure Preparation: Before catheterization, the catheter should be carefully inspected for quality—checking that the tube surface is smooth and the drainage holes are free of rough edges. Any catheter with quality defects must not be used, as patient safety must not be compromised for cost savings.

6. Physiological Factors: In rare clinical cases, female patients may present with urethral hypospadia. It is advisable to prepare two catheterization kits in advance. If the catheter is accidentally inserted into the vagina, it must be replaced immediately. Strict aseptic technique is required during any repeated attempts to prevent infection.

Nursing Measures

1. Continuous Learning: Nursing staff should continuously improve their knowledge of anatomy—particularly the physiological curvature of the male urethra—and develop communication skills to guide and encourage patients in overcoming the difficulties of their condition, thereby supporting recovery.

2. Careful and Gentle Technique: Insertion movements should be slow and gentle, avoiding excessive force. Repeated insertions should be minimized. Select a catheter of appropriate diameter and verify quality before use—even high-priced products that do not meet quality standards must not be used. After catheterization, ensure the catheter is not kinked, compressed, or blocked. Maintain unobstructed drainage. If turbid urine, sediment, crystals, or bleeding is observed, consult a physician immediately for bladder irrigation or hemostasis. Encourage adequate fluid intake in patients with normal renal function.

3. Psychological Care: Catheterization may cause discomfort, and patients with urinary retention may become agitated. Nursing staff should learn to redirect the patient's attention. For patients with prostatic hypertrophy, instruct them to relax the abdominal muscles and breathe deeply to reduce tension and anxiety. If a patient experiences severe discomfort during the procedure, prompt medical assistance should be sought.

Under normal physiological conditions, the human urethra maintains a bacteria-free environment. Catheterization, as a mechanical procedure, inevitably causes varying degrees of trauma to the urethral mucosa, disrupting its protective barrier and potentially leading to complications such as urinary tract infections. Therefore, proper catheterization technique is essential for patient health. Both nursing professionals and patients who self-catheterize should familiarize themselves with proper techniques to minimize the risk of complications.
