目的了解输尿管间嵴肥厚与膀胱后壁肿瘤在声像图上的异同点,减少漏、误诊,为临床诊断提供帮助。方法对已被临床证实的56例膀胱后壁局限性隆起的低回声病例进行超声图像鉴别、分析,比较输尿管间嵴肥厚与膀胱后壁肿瘤在声像图上的异同点。结果输尿管间嵴肥厚与膀胱后壁的肿瘤在声像图上有所不同,具体表现在位置、形态、对膀胱壁的浸润及血流分布情况等方面。结论输尿管间嵴肥厚可能为下尿路梗阻所致的病变,本身并无很大意义,主要的是追查梗阻的原因,而膀胱后壁肿瘤在声像图上的诊断则很有意义,是决定是否手术的关键诊断之一。
Objective To understand the similarities and differences between the ureteral crest hypertrophy and posterior bladder tumor in sonography to reduce leakage and misdiagnosis, and to provide help for clinical diagnosis. Methods 56 cases of clinically confirmed hypoechoic cases with posterior bulging of the posterior wall of the bladder were identified by ultrasound images. The similarities and differences between ureteral crest hypertrophy and bladder posterior wall tumors in sonography were compared. Results ureteral crest hypertrophy and bladder posterior wall of the tumor in the sonographic differences, specifically in the location, morphology, invasion of the bladder wall and blood flow distribution and so on. Conclusions The ureteral crest hypertrophy may be caused by lower urinary tract obstruction, which is of no great significance in itself. The main reason is to trace the cause of obstruction. The diagnosis of bladder posterior wall tumor in sonography is very meaningful and is decided One of the key diagnoses of surgery.
