The primary objective of this study is to assess the potential impact of loss to follow-up on the estimates of treatment effect. The secondary objectives are to describe, for publis...

OBJECTIVE To assess the reporting, extent, and handling of loss to follow-up and its potential impact on the estimates of the effect of treatment in randomised controlled trials. DESIGN Systematic review. We calculated the percentage of trials for which the relative risk would no longer be significant under a number of assumptions about the outcomes of participants lost to follow-up. DATA S...

Patients may present with recurrent flank pain, pyelonephritis, stent migration or encrustation, and ureteral obstruction, with resultant renal failure. Rarely, a long-indwelling period may result in stent fragmentation. Herein, we present a case of a fractured retained ureteral stent noted in a patient lo...
