Metallic catheters are rigid instruments used for urinary drainage, dilation, or diagnostic catheterization. Available in 6–24 Fr sizes for both male and female patients. Preferred when flexible catheters cannot be inserted due to strictures or obstruction. Durable design supports repeated sterilization and long-term use. Provides tactile feedback for surgeons during navigation. Commonly used in urology clinics and operating rooms. Smooth finish minimizes tissue irritation during insertion. Essential for managing complex urinary retention cases. Helps assess urethral passage patency accurately. Compliant with CDSCO norms for urology instruments.
