Renal Angiography And Artery Embolization For Treatment Of Bleeding After Pcnl: Analysis Of 44 Cases

Incidence rates of postoperative renal hemorrhaging after percutaneous nephrolithotomy (PCNL) procedures remain high. Interventional medicine plays an important role in the treatment of renal bleeding. However, results still need to be summarized. Forty-four patients that experienced bleeding after PCNL were enrolled in the current retrospective study. This study also conducted an analysis of interventional procedures used to control hemorrhaging. Application of embolization materials was used in accordance with the actual situation. Of the 44 patients experiencing bleeding after PCNL, 42 patients were found to have abnormal angiographic findings. Another 20 patients showed contrast medium spillover, accounting for 45.45%. A total of 20 patients were embolized using metallic coils plus gelatin sponges, accounting for 47.62%. In conclusion, angiography and embolization techniques are proven effective methods to control renal bleeding after PCNL.
