A 62-year-old man goes to the emergency room (ER) for an intense lower abdominal pain associated with inability to urinate. Physical examination shows tenderness of the lower abdomen bilaterally. Rectal examination reveals an enlarged, smooth, and symmetrical prostate. The ER team fails to pass a Foley catheter through the urethra, and the urology team decides to place a suprapubic catheter to drain the urine and relieve the patient’s symptoms. An ultrasound shows dilation of the collecting system in both kidneys. Laboratory studies show an elevated serum creatinine of 1.6 mg/dL for an estimated glomerular filtration rate (eGFR) of 50 ml/min/1.73 m2. The patient visits the urology team for a follow-up visit 3 weeks after the acute event, in which he claims to have close to normal urination. However, his serum creatinine stays elevated at 1.5 mg/dL. What renal gross findings correlate with this patient’s condition?
