A 62-year-old man presents with left flank pain. Intravenous pyelography reveals delayed excretion and hydronephrosis to the level of a 2.5-cm calculus at the UPJ. Percutaneous stone extraction is accomplished without difficulty, but a postextraction nephrostogram reveals hydronephrosis to the level of the UPJ without residual stonA follow-up nephrostogram 1 week later is unchangeThe best next step is:

A 25-year-old man presents with right flank pain. He underwent a laparoscopic pyeloplasty, which failed within 1 year. Consequently, he underwent failed endopyelotomy. A CT scan shows moderate cortical loss in the right kidney with a normal-appearing left kidney. A renogram reveals 35% differential function on the affected side, and a diuretic study demonstrates functional obstruction (T1 2 > 30â•¯min). The next step is:
