# Situation: A 70-year-old man with benign prostatic hyperplasia (BPH) has had a weak stream and dribbling for several months. He comes to the emergency room because he has not been able to void for 12 hours. His lower abdomen is tender, a firm, rounded mass is felt above the pubis, and his creatinine is 2.1 mg/dL (186 µmol/L). The physician orders insertion of an indwelling urinary catheter. He goes home with the indwelling catheter for 1 week until surgery. On a home visit, the nurse observes his wife's catheter care. Which practice should the nurse correct?

Situation: A 70-year-old man with benign prostatic hyperplasia (BPH) has had a weak stream and dribbling for several months.

He goes home with the indwelling catheter for 1 week until surgery. On a home visit, the nurse observes his wife's catheter care. Which practice should the nurse correct?

1. She changes the bag only when it leaks or is damaged
2. She keeps his catheter taped to his thigh with slack
3. She cleans the meatus with povidone-iodine every day **✔ 정답**
4. She empties the bag into a container used only for him

**정답: 3**

## 해설

Catheter-associated urinary tract infection is prevented with a closed system, a secured catheter, a bag kept below the bladder and off the floor, regular emptying into a clean container, and routine soap-and-water hygiene. Cleaning the meatus with antiseptics adds no benefit and is not recommended, and bags are changed only for leakage, damage, obstruction, or infection rather than on a schedule.

## 심화 해설

The correct practice to correct is cleaning the meatus with povidone-iodine every day. This is a classic exam point about catheter-associated urinary tract infection (CAUTI) prevention, and understanding the underlying principle will help you answer similar questions confidently.

Why antiseptic meatal cleaning is not recommended

The urethral meatus naturally harbors resident flora. Daily application of povidone-iodine or other antiseptics does not reduce the risk of bacteria ascending along the catheter into the bladder. In fact, it can irritate the delicate mucosal tissue, cause local inflammation or excoriation, and disrupt the normal protective skin barrier. This disruption may actually create a more favorable environment for bacterial colonization. Routine meatal care should be performed with plain soap and water during daily hygiene, not with antiseptic solutions. The 2022 SHEA/IDSA guidance explicitly states that antiseptic meatal cleaning adds no benefit for CAUTI prevention [1].

Why the other practices are correct

The wife’s other three actions align with evidence-based CAUTI prevention strategies. Each one supports the principle of maintaining a closed drainage system and minimizing bacterial entry.

| Practice | Rationale | Key principle |
| --- | --- | --- |
| Changing the bag only when it leaks or is damaged | Routine scheduled bag changes break the closed system unnecessarily, increasing infection risk. Change is indicated for leakage, damage, obstruction, or visible infection. | Preserve the closed system |
| Keeping the catheter taped to the thigh with slack | Securing the catheter prevents traction on the bladder neck and urethral meatus, which reduces tissue trauma and movement that can introduce bacteria. Slack prevents pulling during leg movement. | Secure catheter to prevent trauma |
| Emptying the bag into a container used only for him | Using a dedicated, clean container avoids cross-contamination from shared household receptacles. The bag should be emptied regularly, and the drainage spout must not touch the container. | Avoid cross-contamination |

Key point! CAUTI prevention focuses on avoiding unnecessary breaks in the closed system, securing the catheter, keeping the bag below the bladder and off the floor, and using routine soap-and-water hygiene. Antiseptic meatal cleaning is not part of recommended care.

Watch out! Do not confuse meatal care with insertion-site care for other devices. For urinary catheters, sterile technique is used at insertion, but ongoing meatal care is clean, not sterile or antiseptic. Also note that the patient’s elevated creatinine (2.1 mg/dL) and palpable bladder indicate acute urinary retention with postrenal kidney injury, which is why prompt catheterization was ordered—but the home care question focuses on long-term catheter maintenance.

Nurse-driven protocols that standardize these evidence-based practices have been shown to reduce CAUTI rates and catheter utilization, reinforcing that consistent, correct routine care—not antiseptic use—is the protective factor .References (research sources)

## 임상 시나리오

Indwelling Catheter Home CareCAUTI prevention for caregivers
Routine meatal care should use plain soap and water only. Antiseptic solutions such as povidone-iodine are not recommended because they irritate the mucosa and do not reduce CAUTI risk.

Maintain a closed drainage system. Change the collection bag only for leakage, damage, obstruction, or infection, not on a routine schedule.

Secure the catheter to the thigh with slack to prevent tension and urethral injury. Keep the bag below the bladder and off the floor.

CautionEmpty the bag regularly into a dedicated container used only for the patient to prevent cross-contamination. Do not use antiseptics for daily meatal cleaning.

## 핵심 개념

- **CAUTI** — Catheter-associated urinary tract infection, prevented by maintaining a closed drainage system and routine hygiene.
- **Closed drainage system** — A system kept sealed to prevent bacteria from entering the urinary tract through the catheter or collection bag.
- **Meatal care** — Routine cleaning of the urethral opening with plain soap and water; antiseptics are not recommended.
- **Indwelling urinary catheter** — A catheter placed into the bladder and left in place for continuous urine drainage.
- **Benign prostatic hyperplasia (BPH)** — Noncancerous enlargement of the prostate gland that can obstruct urine flow and cause urinary retention.
