[Matrix stones].
We report a case of matrix stone in a patient with a previous history of infective staghorn stone for which the patient had previously undergone surgery to reduce stone volume and ESWL. The ureteral matrix stone had caused purulent intrarenal retention. Puncture nephrostomy and antibiotics resolved the foregoing condition and the calculus was successfully removed by ureteroscopy. The features of this uncommon disorder and the possibilities of endoscopic treatment are discussed.
