    [Abstract]Objective： To analyze the application effect of Pirarubicin (THP) staining localization in the surgical treatment of non-muscle-invasive bladder cancer (NMIBC).Method： The clinical data of 83 NMIBC patients admitted to the Department of Urology， al Chinese Medicine Hospital from January 2022 to July 2023 were retrospectivelyanalyzed.They were divided intotwo groups according todifferent treatment methods. The control group ( n =40) was treated with transurethral resection of bladder tumor， and the observation group (n=43) underwent THPstaininglocalizationby irigationof bladder30min before surgery，andthen transurethralresection of bladder tumor was performed.Theoperation status， tumor markerslevels，secretory regulatory factors levels， tumor recurence and progression were compared betweenthetwo groups.Result：There were no significant diferences in operation time， intraoperative blood loss and postoperative hospital stay between the two groups ( Pgt;0.05 ).
