Blue-light cystoscopy with hexaminolevulinate improves detection of CIS and reduces recurrence. Urine biomarkers (Cxbladder, UroVysion, Bladder EpiCheck) aim to reduce surveillance cystoscopy frequency.","status":"standard-of-care","asOf":"2026-09-07","wikipedia":"https://en.wikipedia.org/wiki/Transurethral_resection_of_bladder_tumor","links":[{"label":"Wikipedia","url":"https://en.wikipedia.org/wiki/Transurethral_resection_of_bladder_tumor"}],"tags":[],"related":[],"cancers":["urothelial"],"sections":["surgery","diagnostics"],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":["nmibc-vs-mibc"],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"principle":"The bladder is visualised endoscopically with white or fluorescence light, and tumours are resected down to muscle with electrosurgery or laser.","strengths":["Organ-sparing","Immediate pathology and staging"],"limitations":["Understaging in ~25% of T1 tumours","Lifelong surveillance burden"]},"route":"/technologies/cystoscopy-turbt/","neighbours":{"cancer":[{"id":"urothelial","kind":"cancer","name":"Bladder & urothelial cancer","route":"/cancers/urothelial/"}],"section":[{"id":"diagnostics","kind":"section","name":"Diagnostics & Biomarkers","route":"/fronts/diagnostics/"},{"id":"surgery","kind":"section","name":"Surgery & Interventional","route":"/fronts/surgery/"}],"term":[{"id":"nmibc-vs-mibc","kind":"term","name":"Non-muscle-invasive vs muscle-invasive bladder cancer (NMIBC / MIBC)","route":"/terms/nmibc-vs-mibc/"}],"idea":[{"id":"idea-urine-ctdna-surveillance","kind":"idea","name":"Urine tumour DNA to replace surveillance cystoscopy in NMIBC","route":"/ideas/idea-urine-ctdna-surveillance/"}],"drug":[{"id":"cxbladder","kind":"drug","name":"Cxbladder","route":"/drugs/cxbladder/"},{"id":"urovysion","kind":"drug","name":"UroVysion Bladder Cancer Kit","route":"/drugs/urovysion/"}],"company":[{"id":"karl-storz","kind":"company","name":"Karl Storz","route":"/companies/karl-storz/"},{"id":"sbi-pharmaceuticals","kind":"company","name":"SBI Pharmaceuticals","route":"/companies/sbi-pharmaceuticals/"}],"technology":[{"id":"bladder-epicheck","kind":"technology","name":"Bladder EpiCheck urine methylation test","route":"/technologies/bladder-epicheck/"},{"id":"photodynamic-therapy-lasers","kind":"technology","name":"Photodynamic therapy lasers and light sources","route":"/technologies/photodynamic-therapy-lasers/"},{"id":"urine-bladder-cancer-tests","kind":"technology","name":"Urine tests for bladder cancer (cytology, FISH, RNA and methylation)","route":"/technologies/urine-bladder-cancer-tests/"}]}}
