FINDINGS: There is an obstructing 4 mm stone at the distal left ureterovesicular junction. FINDINGS: There is a 6 mm stone in the mid to distal left ureter. Multiple staghorn calculi are again seen in the left renal pelvis. The largest measures 2.5 x 0.9 cm in diameter. The NAME_1 appears atrophic. There is a percutaneous nephrostomy tube which appears appropriately positioned in the NAME_1. There is severe hydronephrosis seen on the prior CT on 7/23/2021 is no longer seen. There is no significant dilatation of the left renal collecting system. There is a nonobstructing in the right kidney measuring 7 x 10 mm in diameter. There are no right ureteral stones. IMPRESSION: There are multiple large stones in the left renal pelvis. The largest measures approximately 9 x 25 mm in diameter. IMPRESSION: There is a 6 mm stone in the mid to distal left ureter and a 4 mm stone at the left ureterovesicular junction. Nonobstructing 7 x 10 mm right renal stone. The NAME_1 appears atrophic, unchanged compared with the prior study.
