Phyllanthus niruri and Chrysanthellum americanum in association with potassium and magnesium citrates are able to prevent symptomatic episode in patients affected by recurrent urinary stones: A prospective study

Objective: The aim of this study is to evaluate the efficacy of a food supplement containing Phyllanthus niruri and Chrysanthellum americanum in association with potassium and magnesium citrates in the treatment and prophylaxis of urinary stones.
Materials and methods: Eighty-two patients (mean age 49.7 ± 11.2) with history of urinary stones received this food supplement, one capsule a day for 6 months. Each administration contained a combination of the following ingredients: 244 mg Potassium citrate, 735 mg Magnesium citrate, Phyllanthus (Phyllantus niruri) herb d.e. 15% mg Tannins 220 mg, Chrysanthellum (Chrysanthellum americanum Vatke) plant d.e. ¼ 55 mg. After 6 months, all patients underwent urologic visit, urinalysis, imaging and quality of life (QoL) questionnaires evaluation. Each patient was also evaluated by computed tomography (CT) scan at baseline and at 6 months.
Result: From January 2018 to March 2019, 82 patients (mean age 49.7 ± 11.2) completed the follow-up period and were analyzed. Fifty patients showed lower stone dimensions (60.9%). The average stone size was 0.9 mm, with a significant reduction in comparison with the baseline (-6.7 mm ± 3 mm) (p < 0.001). Forty-nine patients (59.7%) did not show any symptomatic episode with an improving in QoL (+0.4 ± 0.1) (p < 0.001) in comparison with the baseline. At the end of the follow-up period, 27 patients out of 82 were stone-free (32.9%). Moreover, we report a significant reduction of patients with asymptomatic bacteriuria (ABU) between the baseline and the end of the follow-up evaluation (p < 0.001).
Conclusions: In conclusion, this food supplement is able to improve quality of life in patients with urinary stones, reducing symptomatic episodes and the prevalence of ABU.
