The urethrotomy sheath 21 Fr is a specialized instrument used in internal urethrotomy procedures to treat urethral strictures. It provides a stable and clear working channel for the insertion of an optical urethrotome or endoscopic instruments.
The urethrotomy sheath (21 French) is designed for use in optical internal urethrotomy (OIU) procedures to manage urethral strictures. It acts as a working channel and dilator, enabling smooth introduction of endoscopic instruments.
Made from durable material, the 21 Fr sheath allows precise access and visualization of the stricture site while maintaining urethral dilation. Its smooth surface ensures minimal trauma during insertion and withdrawal, enhancing procedural safety and efficiency.
