Systems and methods for inducing negative pressure in a portion of a urinary tract of a patient

A kit comprising:

• (a) at least one ureteral catheter, the at least one ureteral catheter comprising a distal portion configured for insertion within the kidney, renal pelvis and/or ureter and a proximal portion;
• and
• (b) at least one disposable bladder catheter comprising a distal portion configured for insertion within the bladder and a proximal portion configured to transmitxxx negative pressure into the bladder and/or the ureteral catheter, which in turn causes fluid from the kidney to be drawn into and through the ureteral catheter to the bladder, then from the bladder through a drainage lumen of the bladder catheter, and then outside of the body;
• instructions for at least one of the following:
• inserting/deploying the ureteral catheter(s), inserting/deploying the bladder catheter(s) or instructions for connecting a proximal end of the bladder catheter to a pump and for operating the pump to draw urine through the drainage lumen of the bladder catheter.
