Can Patients Shower with a Nephrostomy Tube?
Yes, patients can shower with a nephrostomy tube in place, provided the catheter and connecting device are protected with an impermeable waterproof cover during showering. 1, 2, 3
Key Recommendation
The CDC guidelines explicitly state: "Do not submerge the catheter under water. Showering should be permitted if precautions can be taken to reduce the likelihood of introducing organisms into the catheter (e.g., if the catheter and connecting device are protected with an impermeable cover during the shower)" 1, 2. This is a Category II recommendation, meaning it's supported by suggestive clinical or epidemiologic studies.
Practical Implementation
Protection requirements:
- Use an impermeable waterproof cover over the entire catheter and all connection points
- Ensure the dressing site is completely covered and protected
- The nephrostomy tube insertion site must remain dry
What is absolutely prohibited:
- Never submerge the catheter or catheter site in water 2, 3, 2
- No baths, swimming pools, or hot tubs while the tube is in place
- The ESPEN 2023 guideline reinforces: "The CVAD or CVAD site should not be submerged unprotected in water" (Grade B recommendation) 3
Post-Shower Care
After showering:
- Remove the waterproof covering immediately
- Inspect the insertion site for any moisture
- If the dressing became damp, loosened, or soiled during showering, replace it immediately with a sterile dressing 2
- Clean and disinfect the exit site if any water exposure occurred 3
Rationale for These Precautions
The primary concern is infection prevention. Nephrostomy tubes, like other percutaneous catheters, create a direct pathway from the external environment to internal organs. Water exposure without proper protection significantly increases the risk of introducing pathogenic organisms, potentially leading to:
- Catheter-related infections
- Pyelonephritis
- Sepsis (which can be life-threatening in nephrostomy patients) 4
The evidence shows that sepsis is the most serious complication of nephrostomy tubes, contributing to mortality in some cases 4. Therefore, meticulous attention to keeping the site dry during hygiene activities is critical.
Common Pitfalls to Avoid
- Assuming the dressing alone provides adequate water protection - it does not. An additional impermeable barrier is required
- Allowing water to run directly over the tube site even with a covering
- Delaying dressing changes if moisture penetrates the protective barrier
- Using non-waterproof covers that allow water seepage
This approach balances the important quality-of-life benefit of allowing patients to maintain personal hygiene through showering while minimizing infection risk through appropriate protective measures.
