Glutamine supplementation prevents collagen expression damage in healthy urinary bladder caused by radiotherapy.

Objective: Patients who have had pelvic radiotherapy as part of their cancer therapy may develop subsequent urinary bladder effects such as hyperactive bladder, incontinence, and dysuria. Therefore, the goal of this study was to evaluate whether glutamine supplementation could prevent collagen expression damage in healthy urinary bladder caused by radiotherapy.

Methods: Fifteen adult Wistar rats were separated into a control group that received food and water ad libitum (C group), an irradiated group that received a single pelvic radiation dose of 1164 cGy (I group), and an irradiated group supplemented with l-glutamine every day during the entire experimental period (0.
