He says that the pain started 2 days ago and has gotten worse over time. He has also not been able to urinate over the same time period. On presentation, his temperature is 99F 37.2C, blood pressure is 11072 mmHg, pulse is 105min, and respirations are 12min. Physical exam reveals bilateral flank tenderness. Labs results are shown below:Blood urea nitrogen: 34 mgdLCreatinine: 3.7 mgdlUrine osmolality: 228 mOsmkgRenal ultrasonography shows dilation of the kidneys bilaterally with a normal-sized bladder. Which of the following would most likely be beneficial in treating this patients condition?? A: Administration of a loop diuretic, B: Bilateral stenting of the renal arteries, C: Bilateral stenting of the ureters, D: Catheterization of the bladder, E: Volume repletion with saline,  <response>: This is a patient with acute kidney injury elevated BUN and creatinine and anuria inability to urinate. The ultrasound findings of bilateral hydronephrosis dilation of the kidneys with a normal-sized bladder suggest obstruction of urine flow at the level of the ureters. Choices A and E of administering a diuretic or volume repletion would not be helpful and may be harmful in a patient with anuria. Choice B of stenting the renal arteries would not address the apparent obstruction. Choice C of stenting the ureters and choice D of catheterizing the bladder would both help relieve the obstruction and allow urine to flow from the kidneys. Of these two options, stenting the ureters is more targeted to the apparent site of obstruction and would be the best initial approach.C: Bilateral stenting of the ureters
