Irrigation devices, methods, and systems

An irrigation system, the system comprising:

• a catheter including a first lumen, a second lumen, and an expandable portion, wherein the expandable portion is positioned at a distal end of the catheter;
• a first pump for flowing a dilating agent from a first reservoir, through the first lumen, and into an interior kidney volume;
• a second pump for flowing a contrasting agent from a second reservoir, through the second lumen, and into the interior kidney volume;
• and
• at least one image sensor configured to detect a radiopacity measure in the interior kidney volume,
• wherein the first and second pumps are operable to supply a mixture of the contrasting and dilating agents in the interior kidney volume and flush a portion of the mixture out of an exit port,
• wherein at least one of the first and second pumps are operable to deliver the dilating agent and/or the contrasting agent in order to obtain a target measure in the interior of the kidney volume based on the measure in the interior of the kidney volume, and
• wherein the second pump is operable in response to the radiopacity measure.
