A method of treating nephro-urological disorders, such as kidney stones, phosphate renal calculi formulation, infections connected with urease formation, and abnormal calcium or phosphate excretion is disclosed. The method comprises administration of L-cysteine, or its acid addition salts, in effective amounts to patients suffering from said disorders. In addition, compositions containing the effective compounds are disclosed.

Nephro-urological medicament

The invention provides a novel acidic alkali citrate having the formula K.sub.6 Na.sub.6 H.sub.3 (C.sub.6 0.sub.7 H.sub.5).sub.5 . 2-4 H.sub.2 O made by dissolving either (a) trisodium citrate.times.2 H.sub.2 O, tripotassium citrate.times.1 H.sub.2 O, and citric acid in a mole ratio of 2:2:1 in 3 to 5 times the quantity by weight of boiling demineralized water, based on the weight of the citric acid and maintaining the solution at a temperature not lower than 60.degree. C.; or (b) citric acid at 90.degree. C. while stirring in .01 to 1 times its weight of demineralized water and then adding sodium carbonate and potassium carbonate to give a mole ratio of 3:3:5 of sodium carbonate: potassium carbonate:citric acid, and quick drying the homogeneous solution obtained. Therapeutic agents for the treatment of urolithiasis and removal, or preventing recurrence, of urine stones comprising said acidic alkali citrate are provided.

Acidic alkali citrate and compositions for adjusting the ph of urine

The disclosed invention deals with treating urolithiasis with alizarin. Magnesium oxide and phosphate salts may also be added.

Oral urolithiasis remedy

The invention provides a novel acidic alkali citrate having the formula K.sub.6 Na.sub.6 H.sub.3 (C.sub.6 O.sub.7 H.sub.5).sub.5.2-4 H.sub.2 O made by dissolving either

Acidic alkali citrate and compositions for adjusting the pH of urine

A new compound, viz., aluminum polyhydroxysulfate hydrate of the formula [Al.sub.7 (OH).sub.17 (SO.sub.4).sub.2 .multidot. n H.sub.2 O] where n equals 10-15, preferably 12, has been found to have outstanding therapeutic value in the treatment of urinary stones; the invention thus provides methods of treating phosphate conditions in the urinary passage and compositions for such treatment comprising said new aluminum compound.
