title: [Early calculogenesis caused by ureolytic infection of the double-J ureteral catheter].
abstract: Stone formation in the double J ureteral catheter is an uncommon complication that generally appears in patients that are predisposed to stone formation and persistent infection of the urinary tract. We report on a 29-year-old female patient in whom stone formation was observed in both ends of the catheter, less than 3 months after it had been placed. Urine culture was positive for P. mirabilis. Percutaneous nephrolithotomy was warranted in the treatment of the pyelic stone and for removal of the double J catheter. We underscore the importance of doing urine cultures and radiologic control in this patient group and shortening the time the catheter is left indwelling.
