低分期上尿路上皮癌根治手术不加膀胱袖状切除的可行性分析

目的 分析低分期肾盂及中上段输尿管尿路上皮癌行根治性肾切除术与经典肾盂癌根治性手术后肿瘤复发率的差异,探讨低分期上尿路上皮癌患者不行膀胱袖状切除的可行性.方法 回顾性分析2000-2007年收治73例上尿路上皮癌患者的资料.男36例,女37例.平均年龄66(45～87)岁.其中肾盂癌46例,中上段输尿管癌27例.根据术式分为经典肾盂癌根治性手术组(35例)和根治性肾切除组(38例).分析2组患者病理及随访结果,比较2组患者术后复发率的差异.结果 经典肾盂癌根治性手术组肿瘤复发8例(22.9%),其中T1患者复发率20.0%(3/15);根治性肾切除组肿瘤复发8例(21.1%),其中T1患者复发率19.0%(4/21),2组总复发率和T1肿瘤复发率差异无统计学意义(P>0.05).经典肾盂癌根治性手术组19例肾盂癌中,肿瘤复发4例(21.1%);16例中上段输尿管癌中,肿瘤复发4例(25.0%),2组肿瘤复发率差异无统计学意义(P>0.05).根治性肾切除组27例肾盂癌中,肿瘤复发3例(11.1%);11例中上段输尿管癌中,肿瘤复发5例(45.5%),2组肿瘤复发率差异有统计学意义(P<0.05).结论 低分期上尿路上皮癌患者可不行膀胱袖状切除术,但肿瘤位于输尿管者应行膀胱袖状切除术.

Investigation of low and moderate stage upper urinary tumor with and without concomitant bladder cuff resection

Objective To evaluate the necessity of concomitant bladder cuff and the possibility of distal ureter sparing surgery during radical nephroureterectomy of low-level upper urinary tract tumors. Methods Clinical data of 73 patients with low-level (Tis-T3 M0 N0 ) tumors of the proximal upper urinary transitional epithelial cancer treated in radical nephroureterectomy in our hospital from 2000 to 2007 were analyzed retrospectively. The medical charts and pathologic specimens of 35 patients with, and 38 patients without, concomitant bladder cuff were reviewed. Results In the 35 patients with concomitant bladder cuff resection, 8 cases (22.9%) recurrence was observed; in the 38 patients without concomitant bladder cuff resection, 8 cases (21.1%) recurrence was observed. There was no difference between both groups(P>0.05). In the 19 patients suffered renal pelvis tumors with concomitant bladder cuff resection, 4 cases (21.1%) recurrence was observed; In the 16 patients suffered ureter tumors with concomitant bladder cuff resection, 4 cases (25 %) recurrence was observed.There is no difference between patients of renal pelvis tumors and of ureter tumors with concomitant bladder cuff(P>0.05). In the 27 patients suffered renal pelvis tumors without concomitant bladder cuff resection, 3 cases (11.1 %) recurrence was observed; in the 11 patients suffered ureter tumors with concomitant bladder cuff, 5 cases (45.5%) recurrence was observed. There was significant different between patients of renal pelvis tumors and of ureter tumors without concomitant bladder cuff (P<0. 05). Conclusion Concomitant bladder cuff resection confers a favorable prognosis to the patients with ureter tumors, but not to the patients with renal pelvis tumors.
