From a stone to rupture: calyceal rupture secondary to obstructive uropathy.

Renal collecting system rupture is a rare manifestation of obstructive uropathy. The majority of cases are attributed to ureteric calculi and extrinsic ureteric compression. The optimal diagnostic image is contrast-enhanced CT scan with delayed phase protocol. Management is usually conservative and generally depends on the etiology, urinomas size, and the presence or absence of kidney failure or infections.
