This study is to investigate the effect of valve ablation on bladder function in patients with posterior urethral valves. The clinical data of patients with posterior urethral valves who received urodynamic examination before and after valve ablation were retrospectively analyzed.The bladder compliance improved during urine storage after operation, and the maximum detrusor pressure decreased during micturition. The postoperative urinary system ultrasound showed that the residual urine volume of the group with significantly improved upper urinary tract hydrocephalus was significantly less than that of the group with no improvement. The bladder compliance was significantly higher than that of the group with no improvement, and the maximum urine flow rate was significantly higher than that of the group with no improvement (all P<0.05). Valve ablation has limited effect on improving bladder function in patients with PUV. Valve incision can help improve the maximum bladder volume, residual urine volume and maximum urinary flow rate. It has a certain effect on bladder compliance and maximum detrusor pressure.
本研究回顾性分析20例接受后尿道瓣膜症瓣膜切开手术患儿的临床资料，分析其膀胱功能变化。结果显示，手术前、后膀胱顺应性改善，排尿期膀胱最大逼尿肌压力下降，上尿路积水明显改善组残余尿量显著少于未改善组，膀胱顺应性显著高于未改善组，最大尿流率显著高于未改善组（均P<0.05）。结果表明，后尿道瓣膜症瓣膜切开能改善术后膀胱顺应性、最大逼尿肌压力。手术后上尿路积水是否改善与膀胱残余尿量、顺应性、最大尿流率是否改善有关。.
