Abstract

Abstract: Objective To evaluate the efficacy and safety of pin-shaped electrode in the transurethral en bloc resection of bladder cancer and transurethral holmium laser resection of bladder tumor for non muscle-invasive bladder cancer.Methods One hundred and thirteen cases with non muscle-invasive bladder cancer treated in Beijing Friendship Hospital from March 2015 to October 2017 were assigned to receive transurethral resection of bladder tumor. All the cases were divided into pin-shaped electrode group(n=63) and laser group(n=50) according to the operation method. The operation time, the amount of bleeding, bladder irrigation time, indwelling catheter time, hospitalization time and the recurrence rate in the follow-up period were compared between the two groups, and the data were statistically analyzed.Results All the cases were successfully undergone operation.There were no cases of open surgery and no cases of blood transfusion and no cases of bladder perforation during the operation. All case pathology can meet the requirement of pathological staging. There were 31 Ta cases and 82 T1 cases. There were 77 low grade tumor cases and 36 high grade tumor cases. All patients were followed up for 3-22 months, with an average of (11.4±5.8) months. The tumor recurrence was found in 6 cases in the pin-shaped electrode group(9.5%,6/63) and 7 cases in the laser group(14%,7/50). There was no progression case during the follow up period. There was no significant difference in the operation time, the amount of bleeding, bladder irrigation time, indwelling catheter time, hospitalization time and the recurrence rate in the follow-up period in the two groups(P>0.05).Conclusion Transurethral pin-shaped electrode en bloc resection of bladder tumor is a safe and effective therapeutic method for non muscle-invasive bladder cancer.It can effectively avoid the bladder perforation caused by the obturator nerve reflex and meet the needs of postoperative pathological diagnosis.
