We also sought to identify risk factors associated with ureteral stent (US) failure. METHODS Relying on the Nationwide Inpatient Sample, all patients (≥18 years) who underwent US placement for infected upper tract urolithiasis during the years 1998-2010 were abstracted. A weighted-estimate of 164,546 patients underwent US with or without salvage PCN. Time trend analysis was performed to examine the US failure incidence, using the estimated annual percent change (EAPC) methodology. Logistic regression was performed to estimate the predictors of stent failure. RESULTS Of the 164,546 stents placed during the study period, 97.8% resulted in successful decompression. The rates of successful stent decompression and stent failure increased over time (EAPC 14.05%, p<0.001; EAPC 11.61%, p<0.001, respectively). Middle-aged males with renal stones and acute kidney failure had significantly higher odds of stent failure (p<0.05; Table 1). Salvage PCNs were performed most frequently in urban teaching institutions (OR 1.98, p=0.001; OR 1.83, p<0.001). CONCLUSIONS Ureteral stent decompression for an infected obstructed urinary tract secondary to urolithiasis is almost always effective. For a small proportion of patients, stent failure will occur and may be related to male gender, stone location, and/ or renal failure. Salvage PCNs for these patients occur most frequently in urban teaching hospitals. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e185-e186 Advertisement Copyright & Permissions© 2014MetricsAuthor Information Briony Varda More articles by this author Khurshid R.
