URETHRAL STRICTURE TREATMENT AGENT AND URETHRAL STRICTURE TREATMENT METHOD

摘要

[Problem] The purpose of the present invention is to provide a urethral stenosis treatment agent and a urethral stenosis treatment method that make it possible to avoid the recurrence of stenosis in a minimally invasive transurethral endoscopic procedure performed during urethral stenosis treatment. [Solution] A urethral stenosis treatment agent characterized by containing at least a hydrogel-forming polymer and by having a storage elastic modulus of 50 Pa or less at 10°C and a storage elastic modulus of 100 Pa or more at 37°C. Also provided is a urethral stenosis treatment method characterized by including at least a maneuver in which the urethral stenosis treatment agent is cooled to a temperature of 10°C or less and injected into the inner surface of a urethra subjected to incision during a transurethral endoscopic procedure, then retained in the inner surface of the urethra at a temperature equal to or higher than room temperature.
