Abstract:

Urine system stones are more common in children than in adults. Determining the etiology in the cases of urolithiasis is very important in terms of ensuring success in treatment and preventing recurrence. This study was aimed at investigating the clinical characteristics of stone diseases of the pediatric urine system and potential risk factors. In the Children's Nefrology Clinic, the data of 126 patients followed by the diagnosis of urine system stone disease between 2000-2014 were retrospective. The circumstances were identified in the case, the diagnosis age, family stories, the stone's settlements. In all patients, direct urine microscopic care, full urine examination and urine culture were carried out, calcium, uric acid, oxalate, citrate, magnesium and cystin levels were measured in a daily urine in patients who were able to collect urine for 24 hours, serum electrolyte, blood uric nitrate, creatine, calcium, phosphorus, uric acid, albumin measurements, urine USG and stone analysis (realized with X-ray and diffraction method) participated in the study of 126 facts, which were completed in 14 years of follow-up records. Of these patients, 70 (55%) were men and 56 (45%) were girls. The applicant’s age was 55 months (1-162). In 34% of patients, the family had a stone history.The rate of transmitted urinary tract infection history was 26%. In 34% of cases, the use of vitamin D was high, and in 5% there were high doses. The metabolic risk factor rates were determined as 41% hypercalcium, 30% hypocyturic, 14% hyperoxaluric, 10% hyperuric, and 5% sistinuric. Localization of the stone was observed in 81% of patients in the kidneys, 16.5% in the production, 2.5% in the urine. In stone analysis; in 45% of patients calcium oxalate, in 35% calcium phosphate, in 14,2% uric acid, in 13,3% cystin content was detected. Metabolic assessment and stone analysis should be carried out in order to prevent recurrence in children with urine system stone disease, and should be emphasized for lifelong tracking.
