[Medicinal teas in the prophylaxis of urinary calculus. Effect of solubitrat on the excretion of lithogenic and inhibitory substances (author's transl)].

While adhering to a standardized intake of food and liquids the effect of Solubitrat medicinal tea was tested under hospital conditions on the important serum parameters for urinary calculus formation and on the excretion of lithogenic and inhibitory substances in the urine. No significant differences were found in the serum parameters and in the 24 hr urine between the control group and the trial group. Observation of the day and night rhythm in the urine of the test group showed a prevention of the otherwise normal excretion peaks of most parameters at night, in particular the Ca concentration showing a significant flattening. Solubitrat medicinal tea consequently reduces the risk of urinary calculus formation and can be recommended without restriction for the fluid supply in the prophylaxis of urinary calculus.
