IMMOBILIZATION, A RISK FACTOR FOR URINARY-TRACT STONES IN CHILDREN - A CASE-REPORT

Immobilization causes bone dissolution leading to hypercalcemia and hy percalciuria in children. We report the case of a 10-year-old boy who developed 2 stones in the pelvis off his left healthy kidney after onl y 8 days of immobilization. He was on bedrest after pyeloplasty done f or a ureteropelvic junction obstruction on the right side. Compared to references in Literature our patient showed stone formation very earl y during the course of immobilization. Temporary hypercalciuria and st one formation are well documented because of underlying kidney disease . The risk factors of immobilization-induced hypercalciuria and hyperc alcemia are discussed together with possible treatment and prophylaxis of this pathology.
