Aims: Urinary tract obstructions (UTO) induce tubular injury. The hypothesis explored in this study is that UTO can cause transient proteinuria. The aims of this study were to determine whether patients with UTO have a higher incidence/severity of proteinuria compared with catheterized patients without UTO and whether proteinuria resolves at short term follow-up.
Methods: This was a prospective, matched case control study that included 100 patients; 50 with acute UTO and 50 controls. Proteinuria was quantified using three consecutive 24-hour urinary collections during a week of hospitalization and its incidence, severity, and quantitative changes were compared between the study groups.
Results: Groups were similar by age (83.12±7.94 versus 84.48±9.39 (p=0.44)), major comorbidities, chronic medical treatment and causes of hospitalization. Abnormal proteinuria was observed in all patients with UTO and 94% of the control group. The degree of proteinuria was similar between the groups in the first, second and third 24-hour urine collections (638±419, 828±743, 728±944 vs. 620±639, 648±741, 732±841 mg/24 hours; p=0.88, 0.23 and 0.99, respectively). Proteinuria did not change significantly during a week of in-hospital follow-up in either study group (p=0.19 for trend).
Conclusions: This study demonstrated a very high incidence of significant proteinuria in a cohort of hospitalized patients either with or without acute UTO. Proteinuria does not resolve in the early period after the relief of UTO. Future study with longer follow-up is needed to determine if this proteinuria resolves or persists following hospital discharge and if it has long-term prognostic significance.
