Purpose: Percutaneous nephrolithotomy is considered the golden standard treatment for large renal stone, however, the risk of intraoperative hemorrhage is high. Our study investigate factors that increase bleeding during percutaneous nephrolithotomy, especially focusing on the thickness of renal cortex.
Materials and Methods: We retrospectively review patients underwent PCNL from January, 2016 to January, 2019.One hundred and two patients were enrolled in our study who had completed preoperative laboratory and image survey. All patient was divided into minor blood loss and major blood loss according to post-operation blood transfusion, transarterial embolism and hemoglobin drop>2g/dl. Renal thickness, BMI, stone size, operation time, and preoperative comorbidities are assessed. Logistic regression analyses were used for statistical analysis.
Results: There was no significant difference in the renal thickness between major and minor blood loss (p=0.08). However, height-adjusted cortical thickness showed significant difference between two groups (P=0.03).
Conclusions: Height-adjusted renal cortex thickness had an association with intraoperation blood loss during PCNL.
