Abstract:Objective To investigate the clinical significance of urodynamic study on female bladder leukoplakia patients with transurethral electroresection. Methods Thirty -three female bladder leukoplakia patients who underwent transurethral electroresection surgery from September 2014 to January 2016 were selected. The urodynamic changes of these patients were retrospectively analyzed. Results According to the urodynamic results, 81.1% of the patients suffered from detrusor overactivity, increase of bladder sensation,bladder outlet obstruction and detrusor underactivity, and their incidences were 32.4% (12/37), 21.6% (8/37),16.2% (6/37) and 10.8% (4/37) respectively. Compared to preoperative urodynamic results, the maximum flow rate, average flow rate, maximum cystometric capacity and bladder compliance were increased, and the maximum urethral closure pressure was reduced after operation, the differences were statistically significant (p <0.05). The maximum detrusor pressure, detrusor pressure at maximum flow rate and functional urethral length before and after operation were not statistically different (p > 0.05). Conclusions Most of female bladder leukoplakia patients have lower urinary voiding dysfunction. The urodynamic tests are of great significance in evaluation of lower urinary tract function before and after surgery, estimation of surgical curative effect and application of adjuvant therapy.
