Renal functional outcomes are not adversely affected by selective angioembolization following percutaneous nephrolithotomy

ObjectiveSelective angioembolization (SAE) effectively diagnoses and treats iatrogenic vascular complications following percutaneous nephrolithotomy (PCNL).MethodsWe retrospectively reviewed 1329 consecutive PCNLs and identified patients who underwent SAE following PCNL with at least 12-month follow-up. Estimated glomerular filtration rate (eGFR) was calculated for all patients preoperatively, postoperatively and at last follow-up. A 1:2 matched cohort analysis was performed.ResultsTwenty-three patients underwent SAE and matched to 46 controls. There was no statistically significant difference in preoperative, postoperative, and follow-up eGFR when comparing patients who underwent SAE and those with an uneventful course.ConclusionLong-term eGFR is comparable in patients who undergo uncomplicated PCNL and those requiring SAE.
