Abstract：【Objective】To evaluate the DAP scoring system in T1 stage of renal tumor and selection of surgical methods. 【Methods】Data of 92 patients with T1 stage of renal tumor admitted to our hospital were randomly selected for retrospective analysis. According to the DAP scoring system, 92 patients were divided into 3 groups: the low score group (n=18), the medium score group (n=47) and the high score group (n=27). The correlation of surgical methods, surgical parameters and complications were compared among the three groups. 【Results】Data showed that 3 cases in the low score group, 27 cases in the medium score group and 8 cases in the high score group received open surgery; 13 cases in the low score group, 6 cases in the medium score group and 1 case in the high score group had laparoscopic surgery; 1 case in the low score group, 15 cases in the medium score group and 18 cases in the high score group had radical nephrectomy. There were differences between surgical selections and DAP scores (P<0.05). The DAP scoring system was correlated with surgical approach, duration of operation, duration of warm ischemia and estimated blood loss (P<0.05). It was not correlated with the length of hospital stay or glomerular filtration rate (P>0.05). The incidence of complications was not related to age, body mass index, location of onset and duration of warm ischemia (P>0.05). It was correlated with operation mode, operation duration, blood loss and DAP system score (P<0.05). 【Conclusion】The clinical application of DAP scoring system in patients with T1 renal tumor is helpful for the selection of clinical treatment methods and valuable for clinical prediction of perioperative outcomes.
