摘要
Due to their large size,rapid growth,and attendant morbidity,staghorn calculi are complex clinical entities that impose significant treatment-related challenges.Moreover,their relative heterogeneitydin terms of both total stone burden and anatomic distributiondlimits the ability to standardize their characterization and the reporting of surgical outcomes.Several morphometry systems currently exist to define the volumetric distribution of renal stones,in general,and to predict the outcomes of percutaneous nephrolithotomy;however,they fall short in their applicability to staghorn stones.In this review,we aim to discuss the clinical utility of morphometry systems and the influence of pelvicalyceal anatomy on the management of these complex calculi.
