Impact of low-power laser therapy on peristomal lesions of urinary stomas: case reports

ABSTRACT Objective: To report on the experience of using low-power laser therapy for the treatment of peristomal lesions in patients with urinary ostomies. Method: Report of two cases treated at a stoma therapy service in southern Brazil in 2025. Result: Low-power laser therapy was applied weekly by a trained stoma therapist nurse, with individualized doses and complementary use of photodynamic therapy. The treatment was well accepted, non-invasive, painless, and associated with conventional care. A progressive reduction in lesions was observed, with improved skin integrity and satisfactory patient adherence. Conclusion: Low-level laser therapy has proven to be an effective and safe approach to managing peristomal lesions, promoting healing, symptom relief, and improved quality of life. The importance of professional training and continuous monitoring is reinforced.
