We define IC as a bladder disease with Hunner lesions, usually associated with HSB symptoms and bladder inflammation, and BPS as a condition with HSB symptoms in the absence of Hunner lesions and any confusable diseases.

IC involves immunological inflammation probably resulting from autoimmunity, while BPS is associated with the interaction of multiple factors such as neurogenic inflammation, exogenous substances, urothelial defects, psychological stress, and neural hyperactivity. Histopathology also differs between IC and BPS. IC is associated with severe inflammation of the whole bladder accompanied by plasma cell infiltration and urothelial denudation, while BPS shows little pathological changes.

Overall therapeutic efficacy was divided into good and poor therapeutic efficacies according to changes in the international prostate symptom score (IPSS), IPSS quality of life (IPSS-QOL), and the maximum urinary flow rate. Patients were divided into good and poor therapeutic efficacy groups based on findings obtained 3 months after HoLEP, and comparative assessments were performed between the two groups.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>The therapeutic efficacy of HoLEP was poor in 53 (33.3%) out of 159 patients. Intravesical prostatic protrusion (IPP), IPSS, IPSS-QOL, post-void residual volume (PVR), and the presence of overactive bladder (OAB) were significantly higher in the poor therapeutic efficacy group than in the good therapeutic efficacy group. A multivariable analysis of several factors identified the preoperative presence of OAB and short IPP as independent risk factors for the poor therapeutic efficacy of HoLEP. When treatment efficacy was divided according to risk factors, poor therapeutic efficacy was observed in only 14% of patients with prolonged IPP and the absence of OAB.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>The therapeutic efficacy of HoLEP may be poor in patients with OAB and short IPP, resulting in the significant deterioration of lower urinary tract symptoms. Accordingly, it is important to consider the presence or absence of OAB and IPP measurements when selecting indications for HoLEP.</p>\u0000 </section>\u0000 </div>","PeriodicalId":18028,"journal":{"name":"LUTS: Lower Urinary Tract Symptoms","volume":"16 4","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141620361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
