Percutaneous Management of Calyceal Diverticulum: NYU Case of the Month, September 2020

摘要

A 31-year-old woman presented to NYU Langone with intermittent right flank pain of 6 months’ duration. The pain was sharp, non-radiating, and worsened with fluid intake. The patient had originally been in Italy, where she was diagnosed with kidney stones and underwent 3 ureteroscopic treatments, but her pain persisted. She was unable to provide prior medical records delineating what operations and perioperative care she had been provided in Italy. A recent CT urogram showed a 4-cm right posterior upper pole calyceal diverticulum (CD) with a 9-mm stone (Figure 1). There was no hydronephrosis and the left kidney appeared normal. She had had one prior episode of urinary tract infection (UTI) and had been treated to effect. In the office on presentation, she complained of persistent and intermittent right flank pain but did not display costovertebral angle (CVA) tenderness on examination. Her renal function was normal, with Cr 0.8 mg/ dL and office urinalysis dipstick negative for UTI.
