Spontaneous renal calyceal and ureteric rupture secondary to intravenous contrast during computed tomography intravenous pyelogram.
Upper urinary tract rupture in the absence of trauma is typically related to ureteric calculi causing obstructive nephropathy. Spontaneous extravasation of contrast during CT intravenous pyelography (CT IVP) is infrequently reported. Two cases, who underwent CT IVP to further investigate positive urine cytology and microscopic haematuria, respectively, are described here. In both cases, there was spontaneous extravasation of contrast seen in the postcontrast scans in the absence of ureteric calculi or hydronephrosis which is very unusual.
