What is a urinary ostomy–specific treatment for hyperplasia/pseudoverrucous lesions?

• A. Pouch with appliance with anti-reflux valve
• B. Increase fluid intake and consider cranberry juice
• C. Alter diet and fluid to maintain urine pH around 6.0
• D. Vitamin C

Answer: (A)

Chronic irritation of the peristomal skin from urine exposure leads to pseudoverrucous hyperplasia. The most effective way to treat this in a urinary ostomy is to prevent urine from contacting the skin by stopping backflow and leakage. An appliance with an anti-reflux valve reduces urine reflux toward the stoma, protecting the surrounding skin and allowing the lesions to heal. Other options like increasing fluids for dilution, aiming for a specific urine pH, or taking vitamin C don’t address the mechanical issue of urine on the skin, so they’re not the appropriate targeted approach.
