Abstract：Objective: To compare the efficacy of transurethral bipolar plasma needle electrode vs. annular electrode in the treatment of non muscle-invasive bladder cancer. Methods: From September 2016 to August 2017, 66 cases of urothelial carcinoma admitted in our hospital were diagnosed by urological color Doppler ultrasound and cystoscopy parallel biopsy. The CTU examination suggested no invasion of the bladder wall and no invasion of the upper urinary tract (diameter of 1.0-3.0 cm), and according to the order of hospitalization, the patients were divided into 2 groups, including needle electrode group (33 cases) and ring electrode group (33 cases). The surgical bleeding, catheter indwelling time, hospitalization time, the incidence of obturator nerve reflex, the depth of pathological specimen, and the recurrence rate during the posotoperative follow-up of 4-17 months were statistically analyzed. Results: All operations of the 66 cases were performed successfully under the geneal anesthesia by the same senior resident physician. No block of the obturator nerve area was performed. The tumor was completely removed with needle electrode and ring electrode, and the tumor specimen was complete. The rate of bleeding, indwelling time of urethral catheter, hospital stay, the incidence of obturator nerve reflex, the depth of pathological specimen, and the recurrence rate during the postoperative follow-up of 4-17 months were compared between the two groups. Those in needle electrode group were superior to the ring electrode group (P<0.05). Conclusions: Pin-shaped bipolar plasmakinetic electrode used in transurethral en bloc resection of non muscle-invasive bladder urothelial carcinoma is safe and effective, has low threshold of the technology and equipment, can precisely and completely remove the tumor and reduce the metastasis and planting, has little injury and obturator nerve reflex, and is conducive to accurate staging, etc.
