A Ureteric Catheter (also called a ureteral catheter) is a thin, flexible tube used to access, drain, or diagnose the ureter—the tube that connects the kidney to the bladder. It is commonly used in urology for urine drainage, dye injection, or stenting during procedures like ureteroscopy, pyeloplasty, or stone management.
Key Features of a Ureteric Catheter
Material – Made of radiopaque polyurethane, polyethylene, or silicone—biocompatible and flexible.
Tip Type – Straight or J-shaped (curved) to ease insertion and positioning.
Size – Usually ranges from 3 Fr to 8 Fr in diameter; length ~ 70–90 cm.
Radiopaque Line – Visible on X-ray or fluoroscopy for accurate placement.
End Holes – One or multiple openings at the tip for urine flow or contrast injection.
Sterility – Supplied sterile and single-use.
Connector End – Proximal end may have a universal connector for syringe or drainage bag.
Uses in Medical Procedures
Ureteral Stenting – To relieve obstruction or guide stone removal.
Retrograde Pyelography – Injecting contrast dye to visualize the ureter and renal pelvis.
Urine Drainage – From the kidney to the bladder when natural flow is blocked.
Ureter Identification – During complex pelvic surgeries (e.g., gynecological or colorectal).
