Tailored Kidney Stone Prevention Improves Metabolic Risk Factors and Reduces Renal Colic Rate

Area of Science:

• Nephrology
• Urology
• Metabolic Medicine

Background:

• Limited real-world data exists on combined prophylactic measures for preventing recurrent kidney stone formation.
• Kidney stones (nephrolithiasis) pose a significant health burden, necessitating effective prevention strategies.

Purpose of the Study:

• To evaluate the real-world effectiveness of combined, patient-tailored prophylaxis in managing kidney stone formers.
• To assess the impact of prophylaxis on metabolic risk factors, urinary crystallization indices, and clinical outcomes like renal colic and urological interventions.

Main Methods:

• Single-center retrospective study involving 490 patients with nephrolithiasis.
• Analysis of patient-tailored prophylactic regimens and their effects on metabolic parameters and clinical outcomes over a median follow-up of 12.8 months.

Main Results:

• Significant improvements observed in key metabolic risk factors including urinary volume, oxalate, calcium, and citrate excretion.
• Marked reductions in urinary calcium oxalate supersaturation and the Tiselius risk index.
• Significant decrease in renal colic rates (0.82 to 0.21 per 1000 days at risk) and urological intervention rates (0.31 to 0.21 per 1000 days at risk).

Conclusions:

• Combined, patient-tailored prophylaxis is effective in improving metabolic risk factors and urinary crystallization indices in kidney stone formers.
• This approach leads to a significant reduction in the incidence of renal colic and the need for urological interventions.
• Overall control of metabolic risk factors is associated with a lower rate of renal colic during follow-up.
