Situation: A 30-year-old man with a complete spinal cord injury at the sixth cervical (C6) level from a fall 3 months ago is on a rehabilitation unit. Spinal shock has resolved. His bladder is emptied by intermittent catheterization every 4 hours. His usual blood pressure (BP) is 96/60 mmHg.

He and his mother are preparing to manage his bladder at home. Which instruction about intermittent catheterization is appropriate?

## 보기

1. Catheterize once each morning and once each evening
2. Restrict fluids to about 1 liter a day to stretch intervals
3. Use a new sterile kit and sterile gloves every time
4. Use clean technique with careful handwashing each time **✔ 정답**

**정답: 4**

## 해설

At home, clean intermittent catheterization with thorough handwashing is the standard method and has a low infection risk. Fluid intake is kept adequate, and catheterization follows a schedule that keeps bladder volumes low to prevent overdistension and infection.

Core Concept

A complete C6 spinal cord injury disrupts supraspinal control of the bladder, producing a neurogenic bladder with detrusor overactivity or areflexia, impaired sphincter coordination, and loss of the normal urge-to-void sensation. Once spinal shock has resolved, the bladder does not reliably empty on its own, so scheduled bladder drainage is required to protect the upper urinary tract and prevent complications. Intermittent catheterization (IC) is the preferred method because it mimics normal filling and emptying, keeps intravesical pressure low, and carries a lower long-term infection risk than an indwelling catheter [1].

At home, the standard is clean intermittent catheterization (CIC), also called clean technique. This means careful handwashing, cleaning the meatus, and using a clean—not sterile—catheter each time. Sterile kits and sterile gloves are not required in the home setting because the patient is catheterizing his own bladder in a non-hospital environment, and clean technique has a comparably low infection risk when performed correctly [2][4].

The goal of the catheterization schedule is to keep bladder volumes low enough to prevent overdistension, high-pressure storage, and urinary stasis, which are the main drivers of infection and upper tract damage. For most adults, this means catheterizing every 4 to 6 hours so that each drained volume stays below approximately 400 to 500 mL. Catheterizing only twice daily would allow excessive bladder filling, raising the risk of overdistension, reflux, and bacteriuria. Similarly, restricting fluids to 1 liter per day is inappropriate because concentrated urine irritates the bladder mucosa, promotes bacterial growth, and increases the risk of constipation and dehydration. Adequate fluid intake—generally 1.5 to 2 liters daily unless contraindicated—is maintained, and the catheterization interval is adjusted to the fluid intake and measured volumes [3].

| Comparison | Clean technique (home) | Sterile technique (facility) |
| --- | --- | --- |
| Setting | Home self-catheterization | Hospital or when performed by staff |
| Hand hygiene | Thorough handwashing with soap and water | Hand hygiene plus sterile gloves |
| Catheter | Clean, reusable or single-use clean catheter | Sterile single-use catheter and kit |
| Infection risk | Low with proper technique [2][4] | Low, but no clear superiority over clean technique at home |
| Practicality | Feasible, cost-effective, supports independence | Burdensome, costly, not necessary at home |

Watch out! Do not confuse clean technique with careless technique. Clean intermittent catheterization still requires meticulous handwashing, cleaning of the urethral meatus, and proper catheter handling. The word “clean” refers to the absence of a sterile field, not to reduced hygiene.

Key point! The schedule is based on bladder volume, not the clock alone. If the patient’s fluid intake increases or if drained volumes consistently exceed 500 mL, the interval should be shortened rather than restricting fluids.

For this patient, whose usual BP is 96/60 mmHg, autonomic dysreflexia is a separate but important safety consideration. In a C6 injury, bladder distension or catheter-related stimulation can trigger a sudden, dangerous rise in blood pressure. Keeping the bladder empty on a regular schedule is also a preventive measure against this life-threatening complication, reinforcing why twice-daily catheterization or fluid restriction would be unsafe choices [1][3].References (research sources)

Home Bladder Management After C6 Spinal Cord InjuryClean Intermittent Catheterization Essentials
For a patient with a complete C6 spinal cord injury and resolved spinal shock, scheduled bladder drainage is required to protect the upper urinary tract. Intermittent catheterization is preferred because it mimics normal filling and emptying, keeps intravesical pressure low, and carries a lower long-term infection risk than an indwelling catheter.

At home, the standard method is clean intermittent catheterization (CIC). This means careful handwashing, cleaning the meatus, and using a clean catheter each time. Sterile kits and sterile gloves are not required in the home setting because clean technique has a comparably low infection risk when performed correctly.

The catheterization schedule should keep bladder volumes low to prevent overdistension, high-pressure storage, and urinary stasis. For most adults, this means catheterizing every 4 to 6 hours so each drained volume stays below approximately 400 to 500 mL. Fluid intake should remain adequate, not restricted.

CautionCatheterizing only twice daily allows excessive bladder filling, increasing infection and upper tract damage risk. Restricting fluids to 1 liter per day concentrates urine and raises infection risk without safely stretching intervals.

## 핵심 개념

- **Neurogenic bladder** — Bladder dysfunction caused by disrupted nerve control, common after spinal cord injury, leading to impaired emptying and storage.
- **Clean intermittent catheterization (CIC)** — Bladder drainage using a clean catheter and handwashing technique, the standard home method with low infection risk.
- **Spinal shock** — Temporary loss of spinal reflex activity below the injury level after acute spinal cord trauma, which resolves over weeks.
- **Detrusor overactivity** — Involuntary bladder muscle contractions that can cause high-pressure storage and urinary leakage in neurogenic bladder.
- **Overdistension** — Excessive bladder stretching from infrequent emptying, which impairs blood flow and increases infection susceptibility.
