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

OBJECTIVE: Selective angioembolization (SAE) effectively diagnoses and treats iatrogenic vascular complications following percutaneous nephrolithotomy (PCNL). METHODS: We 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. RESULTS: Twenty-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. CONCLUSION: Long-term eGFR is comparable in patients who undergo uncomplicated PCNL and those requiring SAE.
