[Possibilities of using dietary supplements with antioxidant properties in urinary stone disease].

Introduction: Dietary supplements are successfully used in many fields of medicine, including urology. In particular, urologists often prescribe dietary supplements for patients with urolithiasis.

Aim: to study an influence of dietary supplements Nefradoz on the metabolism of the main stone-forming substances and inhibitors of stone formation in patients with urolithiasis.

Introduction: Dietary supplements are successfully used in many fields of medicine, including urology. In particular, urologists often prescribe dietary supplements for patients with urolithiasis.

Aim: to study an influence of dietary supplements Nefradoz on the metabolism of the main stone-forming substances and inhibitors of stone formation in patients with urolithiasis.

Materials And Methods: A total of 60 patients with urinary stone diseases were included in a single-center prospective randomized study. All patients were divided into 2 groups of 30 people, depending on the treatment. In the main group, patients followed standard diet, received general recommendations and dietary supplements Nefradoz for 28-30 days, 1 capsule (150 mg) 2 times a day with meals. In the control group, patients received only general recommendations and followed standard diet therapy for 28-30 days. The blood biochemical profile and 24-hour urine analysis were evaluated, as well as a urinalysis was performed on daily basis.

Results: In patients receiving Nefradoz, urinary uric acid excretion increased by 0.9 mmol/day. It must be emphasized that an increase in uric acid excretion did not exceed the upper normal limit. A tendency towards an increase in urine excretion of sodium (by 54 mmol / day), magnesium (by 1 mmol / day) and citrates (by 0.6 mmol / day) was also found. The analysis of urinalysis showed that in the main group, urine specific gravity was lower than in the control group. Higher urine pH in the main group compared to the control group was also shown. The severity of hematuria with the use of Nefradoz was almost two times lower than in patients who did not receive dietary supplement.

Conclusion: Considering our data on the ability of dietary supplement Nefradoz to increase the concentration of main inhibitors of stone formation (magnesium and citrates), Nefradoz can be recommended for patients with urinary stone diseases, especially with concomitant hypomagnesuria and hypocitraturia.
