Outcome Measures

Primary Outcomes (1)

  • Assessment of the size, volume and density of stones.

    Computer tomography is the "gold standard" for diagnosing urolithiasis; it will allow you to identify stones, determine their size, density, structure, location, and assess the condition of the urinary tract.

    1 month

Secondary Outcomes (2)

  • Kidney function

    1 month

  • Assessing the composition of stones

    6 months

Study Arms (1)

Citrate therapy for coralloid nephrolithiasis

EXPERIMENTAL

Patients were treated with the citrate mixture "Blemaren"

Drug: anhydrous citric acid - 1197.0 mg, potassium bicarbonate - 967.5 mg, sodium citrate anhydrous - 835.5 mg

Interventions

The dosage was selected individually for each patient, the target pH was considered to be 7.2
