A 63-year-old male was seen for worsening hypertension and mild ankle edema. He was asymptomatic except for irregular urine output over the last few weeks. His blood pressure was 160/95 mmHg (no orthostatic changes), heart, lungs, and abdomen were normal, his prostate was modestly enlarged; and he had 1+ ankle edema. His serum potassium was 6.6 mEq/L, bicarbonate 15 mEq/L, and creatinine 5.8 mg/dL. His creatinine was 0.8 mg/dL 2 years earlier and 1.2 mg/dL 6 months earlier. He had 1+ proteinuria, microscopic hematuria, and his fractional excretion of sodium (FENa) was 1.5 %. Ultrasound showed an empty bladder, bilateral hydronephrosis and hydroureters, and moderate cortical thinning of the right kidney.
