Abstract:
Objective To access the feasibility of ueing "flexible Uitrasonic cystoscopy (FUCS)" (Uitrasonic bronchoscope Olympus BF-UC260F-OL8 as a subslitute) for staging of bladder cancet Methods From Jun 2010 to Nov. 2010,36 patierrts with piiimary bladder urotheiial carcinoma were examined by "FUCS" before operation and were rttaged by "FUCS" findings. All patients rectived IVP and enhanced pdvc CT Non-muscle-invasive bladder cancer patierrts rem-ved TURBT, and the tumor base was routinely bopied for pathology Pathological results, traditional imaging eraliiaiton, and "FUCS" evaluation were compared. Visual analog scores (VAS) were also compared between patierrts reccing "FUCS" and rcmime cystoscopy. Results Compared with conventional cyrtoscopy, the VAS of patients receiving intraoperative "FUCS" was significantly tower (1 3 ± 0. 5 vs 4. 3 ± 0. 9, P<0. 01). Of the 36 patierrts, 28 were diagrosed as non-muscle-invasive bladder cancer (Ta + T1) and 8 were diagrosed as muscle-invasive bladder career (T2 + T3). Based on the postoperative pathologic results, "FUCS" had a 100% accuracy in diagnoeing norem Uselelinvaeive and muscle-invasive bladder cancer. Conclution "FUCS" is painless and feasible in clinical practice; it can display the depth of bladder wall invaded by tumor, and can be used for preoperative staging of primary bladder tumor.
