Evaluation Of Detrusor Function Changes In Patients With Benign Prostatic Hyperplasia After TUPKRP Treatment

Objective:To evaluate the changes of detrusor function in patients with benign prostatic hyperplasia?BPH?after transurethral resection of prostate.Methods:Totally 77 patients with benign prostatic hyperplasia?BPH?were enrolled in this study.Surgical tolerance was assessed.The patients improved the routine urodynamic examination,urinary color doppler ultrasound,international prostate symptom score?IPSS score?,and quality of life index?QoL score?.Among them,23 cases of detrusor enhancement?group A?,32 cases of normal detrusor?group B?and 22 cases of detrusor weakening?group C?were treated with transurethral plasmakinetic resection of the prostate?TUPKRP?.one year postoperatively,the patient consent and signed urine dynamics test informed consent,and through the review of the urinary tract colour to exceed?urine dynamics test evaluation of patients with postoperative maximum urinary flow rate?IPSS score?QoL score?residual urine?bladder outlet obstruction,detrusor function recovery,and carries on the analysis comparison to the prior data.Results:The preoperative and postoperative IPSS scores of A?B and C groups were?preoperation 25.6±2.4 points?23.3±2.6 points?24.5±2.0 points,postoperation 12.4±1.8 points?11.9±1.7 points?17.0±1.7 points?.The preoperative and postoperative Pdet-Qmax values were?114.9±6.6cmH₂O?74.2±4.7cmH₂O?32.7±4.1cmH₂O and94.4±5.7cmH₂O?72.7±4.4cmH₂O?49.0±9.7cmH₂O?.The preoperative and postoperative QoL scores were?4.4±1.0 points?4.1±1.1 points?4.5±0.9 points,2.7±0.9 points?2.4±1.1points?2.6±1.0 points?.The post void residual urine volume?PVR?were?84.7±13.5ml?81.4±12.6ml?101.7±20.6ml,19.2±9.8ml?8.3±3.0ml?41.9±7.4ml?.The maximum flow rate?Qmax?was increased from 8.2±1.1ml/s?7.6±1.1ml/s?5.3±0.8ml/s to 22.4±2.3ml/s?21.9±2.3ml/s?14.9±4.4ml/s.A?B and C bladder Outlet Obstruction Index?BOOI=Pdet-Qmax-2Qmax?were?preoperation98.5±7.3?58.6±5.0?22.2±3.8,postoperation 78.0±6.2?29.0±6.4?19.4±3.4?.bladder contraction index?BCI=Pdet-Qmax+5Qmax?Were?postoperation 156.0±7.9?113.1±5.6?59.1±6.7,preoperative 156.0±7.9,113.1±5.6,59.1±6.7,postoperative 206.4±12.0,182.1±12.0,123.4±31.2?,relative to bladder outlet resistance?BOOI/BCI?were?preoperation 0.63±0.04?0.52±0.04?0.38±0.06,postoperation 0.38±0.03?0.16±0.04?0.16±0.01?,All the indicators were improved to varying degrees,The patient's BOO symptoms improved,Qmax?PVR?IPSS score and QoL score were decreased,and After one year of recovery of the patients with dysplasia,the reexamination of urodynamic examination was better than that of the preoperative diuretic muscle function.the difference was statistically significant?P<0.05?.Conclusion:A?B?C groups of patients after treatment with TUPKRP surgery,patients of group C detrusor function better,some patients back to normal,A,B group of patients with postoperative normal detrusor,BOO symptoms improved.,micturition is obviously improved compared with preoperative,significantly improve the quality of life.
