Prevention and treatment of kidney stones – a complete and specific therapeutic approach


UROCALC™ is an innovative combination of components that, with its synergistic effect, has specific mechanism of action on all factors of kidney stone formation.


  • Treatment of kidney stones
  • Prevention of kidney stone formation in persons who have a high risk of kidney stone formation
  • In persons with metabolic disorders
  • In persons undergoing MET (Medical Expulsive Therapy) or lithotripsy


A complete and specific approach to kidney stone therapy that affects several aspects with a targeted effect aimed at:


  • prevents neoformation
  • inhibites growth 
  • accelerates dissolving


  • stimulates diuresis
  • anti-inflammatory, anti-edematous, and anti-oxidative effect
  • facilitates passing


  • lubricative
  • protective
  • regenerative

Potassium citrates and magnesium citrate are the most important ionic inhibitors that, due to their high affinity for calcium, by inhibiting the crystal formation process (crystallization, growth, and aggregation) and by having an alkylating effect on urine, are of great importance in the prevention of kidney stones.

S&R SPAKs is an exclusive and unique mixture of dry extracts of quarry plants (Phyllanthus niruri, Parietaria officinalis and Ceterach officinarum) that have an antilithiasis effect, by reducing the size and number of kidney stones.

Gooseberry and goldenrod beside the anti-inflammatory, antiseptic, and astringent effect, increase the diuresis and hence promote the elimination and diuresis of excretion of excess body fluids.

BROMELAIN has anti-inflammatory, anti-edematous and anti-oxidative characteristics. Very effective in Medical Expulsive Therapy (MET).  

HYALURON ACID lubricates, protects and regenerates the mucous membrane of the urinary tract.
