Abstract
Objective To evaluate the outcome of super-selective embolization of renal artery for severe hemorrhage after percutaneous nephrolithotomy (PCNL) and its effect on renal function. Methods From May 2008 to Feb 2010,severe bleeding occurred in 7 patients after PCNL in our hospital.(5 males and 2 females,average age of 54.9 years ).All cases were treated with super-selective renal angiography and 6 cases underwent microcoil embolization. Results Renal angiography showed pseudoaneurysm in 5 cases,pseudoaneurysm with arteriovenous fistula in 1 case and no severe bleeding in 1 case.Successful coil embolization was confirmed in 6 cases by angiography,and bleeding stopped within 3 -7 days after embolization.Serum creatinine and blood urea nitrogen were 59 -98 μmol/L(mean,78.3 μmol/L) and 1.86 -6.92 mmol/L( mean,4.8 mmol/L) 2 weeks after embolization,respectively. Conclusions Super-selective embolization of renal artery for severe hemorrhage after percutaneous nephrolithotomy has the advantages of remarkable hemostatic effects and mild impaired renal function,which is of the first choice.
