case_images: In June 2008, a 58-year-old female patient with history of breast cancer (s/p radical mastectomy and chemotherapy in 2000), kidney stones, and congenital megacalycosis of the left kidney developed renal colic secondary to large obstructing calculi, causing secondary ureteropelvic junction obstruction (Fig. 1).

case_images: TCC of the lower pole calix was noted (Fig. 2a, b). The nephrostomy tube (NT) was left indwelling until the percutaneous tract matured and urine cleared, and 2 weeks later in July 2008, the patient was taken for repeat percutaneous endoscopy; there were no residual urothelial tumors noted in the kidney and the entire ureter, and the NT was removed.
