摘　　要：目的:研究膀胱癌术前活检较术后病理分级低估可能的原因。方法:总结75例术前膀胱镜活检诊断膀胱癌,术后病理检查资料完整的患者分级进行比较分析。结果:75例患者术前活检病理分级G122例,G249例,G34例;术后标本病理分级为G12例,G226例,G347例;术前活检病理分级与术后标本病理分级一致22例(29.33%),活检低估分级50例(66.67%),高估分级3例(4.00%),三组比较存在显著性差异(P<0.01)。结论:膀胱癌的术前活检与术后病理分级比较存在低估现象,充分重视低估现象可避免治疗不足的发生。Objective：To study the histologic grade between biopsy and postoperative specimen in bladder transition cell carcinoma and explore the reasons of underestimation. Methods ： Seventy five cases of bladder transition cell carcinoma were summarized and classified by biopsy preoperative and postoperative specimen. Results： Among 75 patients cases ,49 cases ,4 cases were G1 , G2 , G3 by biopsy preoperatively, respectively, and 2 cases ,26 cases ,47 cases were G1 , G2, G3 by postoperative specimen. There were 50 cases （66.67 % ）underestimated the histologic grade by biopsy preoperatively, 3 cases （4.00%）overestimated preoperatively, 22 cases （29.33%）accord （P 〈 0.01 ）. Conclusion： There is the underestimation phenomenon in histologic grade between biopsy and postoperative specimen in bladder transition cell carcinoma diagnosis and we should pay attention to this phenomenon.
