摘要：
Ureteral or bladder catheters are provided, including (a) a proximal portion； and (b) a distal portion, the distal portion including a retention portion that includes one or more protected drainage holes, ports or perforations and is configured to establish an outer periphery or protective surface area that inhibits mucosal tissue from occluding the one or more protected drainage holes, ports or perforations upon application of negative pressure through the catheter. Systems, kits and methods for inducing negative pressure to increase renal function also are provided.
