概括
与健康对照组相比,切割波弹性图 (SWE) 显示神经性膀 (NB) 的儿童的膀壁度更高. 然而,SWE与上下泌尿道疾病没有相关性,这限制了其目前的临床使用.
科学领域:
- 儿童泌尿病学
- 生物医学工程
- 医学成像
背景情况:
- 在儿童中,神经性膀 (NB) 与膀壁硬度的增加有关.
- 量化膀壁硬度的非侵入性方法有限.
- 剪波弹性图 (SWE) 是评估膀弹性的潜在非侵入性工具.
研究的目的:
- 评估SWE是否能够区分儿童的神经性膀和健康膀.
- 研究SWE测量与NB儿童上下泌尿道常规检查之间的相关性.
主要方法:
- 涉及NB儿童和年龄相匹配的健康对照的前性单中心研究.
- 使用SWE测量膀壁弹性,在充满和空隙后状态下量化Young的弹性模块 (YME).
- 使用混合效应模型进行统计分析,以比较YME值并将其与临床参数相关联.
主要成果:
- 与对照组相比,患有NB的儿童在充满膀 (9. 95 kPa vs 7. 50 kPa) 和空气后 (9. 30 kPa vs 6. 80 kPa) 状态下显示出显著更高的YME值.
- 在NB患者和对照人群中,YME (ΔYME) 的变化没有显著差异,这表明空化后没有系统的硬化或放松.
- 没有发现YME值与各种临床小组之间有显著的关联,包括水尿管缩症,膀管回流或体过活.
结论:
- 与健康对照组相比,SWE可以在患有NB的儿童中区分出更高的膀壁硬度.
- 目前的SWE测量与NB的常规上下泌尿道检查无关.
- 目前,SWE是一个补充研究工具,而不是在NB管理中取代已有的诊断方法.

Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

01:23Urinary Bladder
1.4K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...
