Influence of risk factors of osteoporosis on calcium excretion in patients with urolithiasis

Objective. To improve diagnosis and treatment of patients with UL who underwent operative treatment.
Patients and methods. We performed a questionnaire study of the risk factors of osteoporosis in 88 patients with UL who underwent surgery. After discharge from hospital and normalization of the parameters of urine analysis and culture test, we examined 24-hour calcium excretion in patients.
Results. The patients’ age was 47.7 ± 14.2 years. Risk factors of OP were found in 44 (50.0%) patients. The age of patients with risk factors of OP was significantly higher (р = 0.013). 24-hour calcium excretion was 5.3 ± 2.7 mmol/day. 24-hour diuresis was 26 ± 9.7 mL/kg/day. A positive significant correlation was noted between 24h diuresis per kg of body weight and 24h calcium excretion (y = 4.7 + –0.04 x, р = 0.005).
Conclusion. We found risk factors of osteoporosis in 50% of examined patients with UL. More marked calcium excretion was noted in patients with UL who had risk factors of osteoporosis as compared with patients who did not have such risk factors.
Key words: urolithiasis, osteoporosis, calcium excretion.
