Mesmo com aumento da ingestão de água, estudos mostram que prevenir pedras nos rins segue sendo um desafio complexo e pouco previsível.

Cálculos renais causam dores intensas e levam milhões ao pronto-socorro, com alta recorrência mesmo após mudanças de hábitos e orientação médica.

Nos Estados Unidos, cerca de 1 em cada 11 pessoas desenvolve pedras nos rins, e quase metade enfrenta novos episódios ao longo da vida.

Um grande estudo clínico da Duke University testou se programas estruturados de hidratação poderiam reduzir a recorrência de cálculos renais.

A pesquisa publicada na The Lancet avaliou mais de 1.600 participantes por dois anos com intervenções como metas e garrafas inteligentes.

Mesmo com aumento no consumo de líquidos e maior produção de urina, o estudo não encontrou redução significativa na recorrência de cálculos renais.

A intervenção incluiu lembretes, metas personalizadas, acompanhamento digital e incentivos, mas a adesão à hidratação ideal foi difícil de manter.

Os resultados indicam que metas únicas de ingestão de água podem não servir para todos, já que necessidades variam conforme idade e saúde.

Pesquisadores sugerem estratégias mais personalizadas para prevenção, combinando comportamento, tecnologia e terapias para reduzir cálculos urinários.
