“…Recent data suggest hypocitraturia could contribute to disease progression because, in an animal model of polycystic kidney disease, calcium microcrystal deposition triggered tubule dilation, cyst initiation, and growth, which was prevented by citrate therapy (3). In addition, in cross-sectional studies, urinary citrate levels correlated with total kidney volume (TKV) and eGFR (4,5). To address the hypothesis that lower urinary citrate levels could predispose patients with ADPKD to a faster disease progression, we performed a single-center, retrospective study.…”
