The treatment for urethral stricture is UREGROW® epithelial cell therapy. It is a natural and biological treatment for urethral stricture. Helps restore normal urinary flow and private function, improving quality of life. UREGROW® for the treatment of urethral strictures uses autologous cells (the patient's own cells) as a therapeutic agent to heal urethral strictures. The treatment process involves the removal of buccal cells from the inside of the cheek, followed by the proliferation and implantation of epithelial cells. The implantation of epithelial cells regenerates the epithelial layer at the site of the narrowing and relieves symptoms.
