Kurzfassung:
Radical nephrectomy and thrombectomy is the standard surgical procedure for the treatment of renal cell carcinoma (RCC) with tumor thrombus (TT). But the estimation of intra-operative blood loss is only based on the surgeon's experience. Therefore, our study aimed to develop Peking University Third Hospital score (PKUTH score) for the prediction of intra-operative blood loss volume in radical nephrectomy and thrombectomy. Methods The clinical data of 153 cases of renal mass with renal vein (RV) or inferior vena cava tumor thrombus admitted to Department of Urology, Peking University Third Hospital from January 2015 to May 2018 were retrospectively analyzed. The total amount of blood loss during operation is equal to the amount of blood sucked out by the aspirator plus the amount of blood in the blood-soaked gauze. Univariate linear analysis was used to analyze risk factors for intra-operative blood loss, then significant factors were included in subsequent multivariable linear regression analysis. Results The final multivariable model included the following three factors: open operative approach ( P 〈 0.001), Neves classification IV ( P 〈 0.001), inferior vena cava resection ( P = 0.001). The PKUTH score (0–3) was calculated according to the number of aforementioned risk factors. A significant increase of blood loss was noticed along with higher risk score. The estimated median blood loss from PKUTH score 0 to 3 was 280 mL (interquartile range [IQR] 100–600 mL), 1250 mL (IQR 575–2700 mL), 2000 mL (IQR 1250–2900 mL), and 5000 mL (IQR 4250–8000 mL), respectively. Meanwhile, the higher PKUTH score was, the more chance of post-operative complications ( P = 0.004) occurred. A tendency but not significant overall survival difference was found between PKUTH risk score 0 vs . 1 to 3 ( P = 0.098). Conclusion We present a structured and quantitative scoring system, PKUTH score, to predict intra-operative blood loss volume in radical nephrectomy and thrombectomy.
