[Calcium nephrolithiasis and phosphate therapy. Long term study (65 cases) (author's transl)]
Protected phosphate therapy significantly reduces recurrent calcium kidney stones by over 60%. This treatment also alleviates hypercalciuria and associated symptoms with minimal side effects, offering an effective solution for kidney stone patients.
Area of Science:
- Nephrology
- Urology
- Biochemistry
Context:
- Recurrent calcium nephrolithiasis poses a significant health challenge.
- Existing treatments have limitations and varying efficacy.
- Phosphate therapy offers a potential therapeutic avenue.
Purpose:
- To evaluate the efficacy and safety of protected phosphate therapy in patients with recurrent calcium nephrolithiasis.
- To assess the impact of phosphate therapy on stone formation, renal colic frequency, and related symptoms.
Summary:
- A study involving 65 patients with recurrent calcium nephrolithiasis demonstrated that protected phosphate therapy reduced renal colics by over 60% and stone formation by over 60%.
- The treatment also led to a decrease in hypercalciuria, asthenia, spasmophilia symptoms, and bone pain.
- Observed side effects were minor, primarily digestive issues, with few requiring treatment discontinuation or dose reduction.
Impact:
- Phosphate therapy proves to be an efficient and well-tolerated treatment for recurrent calcium nephrolithiasis.
- The mechanism involves reducing urinary calcium levels and increasing urinary pyrophosphates, which inhibit calcium crystallization.
- This therapy offers a promising approach to manage and prevent calcium-based kidney stones.
