To determine tumor stage, 115 bladder cancer patients with cystoscopic suspicion of invasion underwent transurethral ultrasonic scanning. Seventeen patients who had received radiotherapy were excluded because it proved impossible to differentiate between tumor and irradiation sequelae. Of the remaining 98 examinations, 4 (4.1%) were inconclusive, 73 tumors (74.5%) were correctly staged, 16 tumors (16.3%) were overstaged and 5 tumors (5.1%) understaged. Transurethral ultrasound is regarded a useful supplement to cytoscopy and biopsy in staging of bladder tumors suspected of invasion.
为确定肿瘤分期，115例经膀胱镜检查怀疑有浸润的膀胱癌患者接受了经尿道超声扫描。17例接受过放射治疗的患者被排除，因为无法区分肿瘤和放疗后遗症。在其余98例检查中，4例（4.1%）结果不明确，73例肿瘤（74.5%）分期正确，16例肿瘤（16.3%）分期过高，5例肿瘤（5.1%）分期过低。经尿道超声被认为是对怀疑有浸润的膀胱肿瘤进行分期时膀胱镜检查和活检的有用补充。
