Abstract
Ureteral catheters are provided including a drainage lumen including a distal portion configured to be positioned in a patient's kidney, renal pelvis and/or in the ureter adjacent to the renal pelvis for receiving fluid from a patient's kidney and a proximal portion for draining the fluid from the distal portion, the distal portion including a coiled retention portion including: at least a first coil having a first diameter; at least a second coil having a second diameter, the first diameter being less than the second diameter, the second coil being closer to an end of the distal portion of the drainage lumen than the first coil; and one or more perforations on a sidewall of the coiled retention portion of the distal portion of the drainage lumen for permitting fluid flow into the drainage lumen, wherein the proximal portion of the drainage lumen is essentially free of or free of perforations.
