Chronic non-stone-related hydronephrosis from supravesical or bladder dysfunction in adults is often detected incidentally. This study aims to review the literature regarding supravesical obstruction or bladder dysfunction leading to bilateral hydronephrosis in adults and to develop an algorithm to identify patients at risk of renal failure. Cross-sectional studies, retrospective and prospective cohorts, clinical trials, and systematic reviews from 1980 to 2017 were included. From 8115 articles screened, 39 met the inclusion criteria. Despite the lack of studies addressing this issue, this review brings up a rational evidence-based algorithm to diagnose and manage adults with bilateral hydronephrosis due to supravesical or bladder disease or dysfunction.
