Value of CT angiography in reducing the risk of XXXX associated with mini-percutaneous nephrolithotomy.

PURPOSE: To evaluate the clinical value of computed tomography angiography (CTA) in reducing the risk of @entity548 associated with mini-percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: A total of 158 @entity1 with renal or ureter stones who had undergone mini-percutaneous nephrolithotomy were retrospectively enrolled into this study from May of 2011 to April of 2014. Group 1 (65 @entity1 ) underwent computed tomography angiography, and Group 2 (93 @entity1 ) underwent non-contrast CT. The clinical characteristics of the @entity1 and @entity548 were recorded. The hematologic complications (transfusion rate, and preoperative and postoperative hemoglobin values) were assessed. RESULTS: There were no statistically significant differences in age, body mass index(BMI), stone diameter, operative time, stone-free rate, and hospital stay between the 2 groups. In group 2, 1 @entity1 (1.1%) developed a @entity8 and was treated with embolus therapy. In addition, Group 2 showed significantly drop in hemoglobin (3.6 g/dL vs. 2.4 g/dL, respectively; P < 0.001) and more transfusions (9.7% vs. 1.5%, respectively; P < 0.05) compared with Group 1. CONCLUSION: The study showed that @entity1 who underwent computed tomography angiography prior to percutaneous nephrolithotomy had lower drop of hemoglobin and needed less transfusions. These findings may suggest that the use of computed tomography angiography may reduce the risk of bleeding during percutaneous nephrolithotomy.
