Giant calcifications of a double-J ureteral catheter

We present a case of recurring gigantic calcifications of both extreme of a double-J ureteral catheter, with long permanency of the same. We expose the technical maneuvers that were specified for the managing of so important complication. We emphasize the renal functional conservation found in spite of the magnitude of the calcifications. We check the national literature in this regard of this complication and we expose the etiological mechanisms, prophylactic recommendations and therapeutic managing of this complication to the extended use of ureteral catheters.
