Abstract:
Objective To discuss the indication for kidney-sparing surgery (KSS) on primary urothelial carcinoma of the distal ureter.MethodsClinical data of 108 patients with primary urothelial carcinoma of the distal ureter in our hospital from 2001 to 2009 were analyzed retrospectively.There were 75 males and 33 females with mean age of 62 ( range from 42 to 85 ) years old in this study.The patients were divided into KSS group and RNU group according to the operation methods.The recurrence rate of radical nephroureterectomy (RNU) and KSS were evaluated.Results The recurrence was seen none with T,stage,1 (12.5％) with T1 stage,4 (36.4％) with T2 stage and 4 (80％) with T3 stage in KSS group.In RNU group,there was none with Ta stage,4 ( 15.4％ ) with T1 stage,10 (33.3％) with T2 stage and 7 (36.8％) with T3 stage recurred.There was no difference between patients with Ta to T2 stages in KSS and RNU group (P ＞0.05 ) on recurrence,but there was a significant difference between patients with T3 stage (P＜0.05).There was 1 (33.3％) case with G1 grade,3 (18.8％) with G2 grade and 5 (62.5％) with G3 grade recurred in KSS group,while 2 (22.2％) cases with G1 grade,9 (20％) with G2 grade and 10 (37.0％) with G3 grade recurred in RNU group.There was no difference between patients with G1 to G2 grades in KSS and RNU group (P＞0.05),but there was a significant difference between patients with G3 stage in the two groups ( P ＜ 0.05 ).Conclusion KSS seems to be safe for patients with low stage and low grade primary urothelial carcinoma of the distal ureter.
