ABSTRACT
Objective To investigate the clinical effect of the 1 470 nm diode laser for the treatment of superficial bladder tumor.Methods Two hundreds and sixteen patients diagnosed with superficial bladder tumor were treated in our hospital from January 2012 to January 2014 and divided into the laser group and electric cutting group.The two groups were treated by 1 470 nm diode laser and transurethral plasma kinetic resection respectively.The basic data and the observation indexes were compared be tween the two groups.Results The operation time,intraoperative bleeding volume,indwelling catheter time and hospital stay time in the laser group were significantly less than those in the electric cutting group.The levels of epinephrine,norepinephrine and an giotensin Ⅱ in operation and at postoperative 6 h in the laser group were significantly lower than those in the electric cutting group (P＜0.05).The obturator nerve reflex and bladder perforation did not occur in the laser group,and the total complications occurrence rate was 5.1％,the bladder tumor recurrence rate in postoperative 24 months was 7.1％.The obturator nerve reflex occurrence rate was 7.6％,the vesical perforation rate was 1.7％,the total complications occurrence rate was 15.3％,the bladder tumor recurrence rate in postoperative 24 months was 17.8 ％ in the electric cutting group.The above indexes of the laser group were significantly lower than those of the electric cut group(P＜0.05).Conclusion The 1 470 nm diode laser for the treatment of noninvasive superficial bladder tumor has definitely curative effect,is easy to operate with low postoperative complication occurrence rate,high safety and low middle and long term recurrence rate,moreover has little influence on patient's stress level.
