Bovine glutaraldehyde cross-linked collagen is an injectable bulking agent used to treat urinary incontinence and vesicoureteral reflux. A 16-year-old girl had previously undergone left subureteral injection of collagen at the age of 6 years. She presented to our clinic after passing a 7-mm calcification with a history of hematuria and intermittent back pain. Computed tomography showed two hyperdense foci measuring 2 mm each in the region of the left ureterovesical junction that did not change on follow-up imaging. On cystoscopy, two submucosal calcifications were located medially and inferiorly to the left ureteral orifice and were removed endoscopically.
