The Value Of IPSS-V/S In Assessing Lower Urinary Tract Symptoms After TUVP

Objective:To investigate the clinical value of International Prostatic Symptom Score-Voiding/Storage subscore ratio(IPSS-V/S)in assessing lower urinary tract symptoms(LUTS)after transurethral electrovaporization prostatectomy(TUVP).Methods:A retrospective analysis was performed for International Prostatic Symptom Score(IPSS)and other clinical data of 234 patients with benign prostatc hyperplasia(BPH)who underwent TUVP from January 2015 to December 2016 in the First Affiliated Hospital of Soochow University.According IPSS-V/S,these patients were divided into Group A(80 patients with an IPSS-V/S≤1)and Group B(154 patients with an IPSS-V/S>1).IPSS,IPSS-V,IPSS-S and Quality of life(QOL)were reassessed at 6 month after surgery.At 6 months after surgery,group B had a significantly greater improvement in IPSS than group A[(12.36±3.67)points vs.(8.20±3.21)points,t=8.96,P=0.000].At 6 months after surgery,group A had a significantly higher IPSS-S score thanResults:At 6 months after surgery,group B had a significantly greater improvement in IPSS than group A[(12.36±3.67)points vs.(8.20±3.21)points,t=8.96,P=0.000].At 6 months after surgery,group A had a significantly higher IPSS-S score than group B[(9.61±2.88)points vs.(5.55±2.63)points,t=10.8,P=0.000],While there was no significant difference in IPSS-V score between the two groups(t=1.56,P=0.120).Although group A had a significant improvement in QOL score at 6 months after surgery[(3.59±0.91)points vs.(5.19±0.55)points,t=14.8,P=0.000],group A had a significantly lower satisfaction rate than group B(13.75%vs.70.78%).At 6 months after surgery,group A had varying degrees of improvement in IPSS-S symptom scores,among which the score of urgency of urination showed the highest degree of improvement,followed by the scores of frequency of urination and nocturia;the score of nocturia had the lowest improvement rate of 36.3%(29/80),which was an important reason for the lower degree of improvement in IPSS and QOL.Conclusion:Compared with IPSS,IPSS-V/S can reflect the outcome after TUVP more accurately,the voiding symptoms had significantly greater improvements than storage symptoms in LUTS.BPH/LUTS patients with nocturia as the main complaint have limited improvement in QOL after TUVP,which should be taken seriously by clinicians.
