1. A catheter configured to be deployed in a urinary tract, comprising:
(a) a proximal portion, wherein the proximal portion is essentially free or free of drainage holes; and
(b) a distal portion comprising a retention portion configured to be deployed in a kidney and/or a renal pelvis, the retention portion comprising one or more drainage holes leading to one or more lumen(s) within the proximal portion,
wherein the retention portion, when deployed, defines a three-dimensional shape sized and positioned to maintain patency of fluid flow between the kidney and/or renal pelvis and a proximal end of the catheter by inhibiting mucosal tissue from appreciably occluding the one or more drainage holes when negative pressure is applied through the catheter.
