Clinical and demographic characteristics of children with urolithiasis: single-center experience from eastern Turkey.

OBJECTIVE: To evaluate the clinical and demographic findings of children with urolithiasis in eastern Turkey.

METHODS: We retrospectively reviewed the medical records of 67 children with urolithiasis for clinical and laboratory data.

RESULTS: Mean age at the time of diagnosis was 39.1 +/- 41.2 months. Complaints at admission were: urinary tract infection (29.9%), macroscopic hematuria (26.9%), abdominal or flank pain (19.4%), spontaneous passing of the stone (8.9%), growth and developmental delay (7.5%), and non-specific findings (8.9%). A family history of urolithiasis was positive in 50.7% of patients. Metabolic screening could be performed in 47 (70.1%) of patients due to socioeconomic problems and revealed hypercalciuria in 59.6%, infectious stone in 17%, cystinuria in 6.4%, hyperuricosuria in 10.6%, hyperoxaluria 4.3%, and hypocitruria in 2.1%. Stone analysis of patients (26.9%) revealed calcium oxalate in 38.9%, calcium phosphate in 22.2%, uric acid in 16.7%, cystine in 11.2%, struvite in 5.6% and mixed content in 5.6%.

CONCLUSION: We believe early diagnosis with detailed metabolic screening and appropriate treatment and follow-up procedures and the contribution of urolithiasis to end-stage renal disease can be avoided.
