概括
在小儿脊柱裂患者中确定了标准化的膀形状. 气管和"圣诞树"形状与更高的膀压力相关,但不一定与其他功能障碍指标相关.
科学领域:
- 儿童泌尿病学
- 神经神经病学
- 医学成像
背景情况:
- 脊柱裂通常会导致膀功能障碍.
- 在这个群体中缺少膀形状的标准化术语.
- 膀的形状可能表明潜在的功能障碍.
研究的目的:
- 在光镜图像上提出儿童膀形状的标准化术语.
- 评估膀形状与填充压力之间的关系.
- 确定膀形状是否与膀功能障碍的其他测量结果相关.
主要方法:
- 对接受视频泌尿动力学治疗的儿科脊柱裂患者进行横截面研究.
- 无监督的集群分析和临床专家对膀形状的分类 (圆形,长方形,"圣诞树",光滑,形).
- 在不同形状类别中比较膀填充压力和临床功能障碍.
主要成果:
- 分析了四百一十七名儿童患者.
- 与光滑膀相比,形膀和"圣诞树"膀的填充压力明显更高.
- 膀形状的差异与膀外流,泄漏和外关节功能失调有关,但与水解或功能障碍的严重程度不一致.
结论:
- 为儿童脊柱裂形成了一个标准化的膀形状命名法.
- 膀轮和"圣诞树"形态与更高的填充压力有关.
- 膀形状本身不足以一致预测所有类型或严重程度的膀功能障碍.

Urodynamic Studies: Uroflowmetry
534
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...

Imaging Studies VI: Voiding Cystourethrography and Cystography
112
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...

Urinary Bladder
1.5K
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...

Anatomy of the Genitourinary System II: Bladder and Urethra
208
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...
