1. A ureteral catheter configured to be deployed in a urinary tract, comprising:
an elongated tube comprising a proximal portion configured for placement in a ureter, a distal portion comprising a distal end, and a sidewall extending between a proximal end and the distal end of the elongated tube defining at least one drainage lumen extending through the tube; and
a permeable material directly or indirectly connected to the distal portion of the elongated tube and extending axially and/or radially therefrom, the permeable material being configured to be deployed in the urinary tract to maintain the distal end of the elongated tube at a predetermined position in a ureter, a renal pelvis, or a kidney, wherein the ureteral catheter is free of a balloon,
wherein, when deployed, the permeable material defines a three-dimensional shape of sufficient size to permit flow of at least a portion of fluid from the urinary tract through the permeable material and drainage lumen of the elongated tube upon application of negative pressure through the catheter, wherein a diameter of a distal portion of the three-dimensional shape of the permeable material is greater than a diameter of a proximal portion of the three-dimensional shape of the permeable material.
