概括
洞穴体 (CC) 的外部旋转 (ExR) 在经典膀外缩 (CBE) 时显著改善尿道覆盖. 这种新的技术与内部旋转 (InR) 相比,提供了更好的结果,特别是在年长的儿童中.
科学领域:
- 儿科泌尿外科 儿科泌尿外科
- 重建性手术是一种重建性手术.
- 解剖学研究 解剖学研究
背景情况:
- 经典膀外缩 (CBE) 在表皮修复 (ER) 期间实现充分的尿道覆盖面对手术提出了挑战.
- 洞穴体 (CC) 的传统内部旋转 (InR) 可能并不总是提供最佳结果.
- 需要新的外科手术技术来提高CBE的ER结果.
研究的目的:
- 介绍和评估一种新的外科手术操作:CC的外部旋转 (ExR).
- 量化比较ExR与InR在CBEER期间改善尿道覆盖和阴茎长度方面的疗效.
- 确定患者年龄与ExR的益处之间的相关性.
主要方法:
- 对29名患者 (11-59个月) 的回顾性分析,这些患者接受了初级ER,之前膀关闭.
- CC动员和神经血管束剖析,以允许InR和ExR.
- 患者作为他们自己的对照,尿道覆盖和阴茎长度在两个旋转技术后测量.
主要成果:
- 与InR相比,ExR显著改善了尿道覆盖范围 (平均差异:9.79毫米;p < 0.0001).
- 覆盖率的增加与ExR与患者年龄正相关 (rho = 0.6182,p = 0.0004).
- 发生了两个尿路皮质囊 (6.9%),其中一个需要手术修复.
结论:
- CC的外部旋转 (ExR) 是一种简单而有效的修改,用于提高CBE的ER中的尿道覆盖率.
- ExR是传统InR的可取替代方案,特别是在具有充足尿道板的患者中.
- 建议对长期结果数据进行进一步研究,以支持ExR的广泛采用.

Anatomy of the Genitourinary System II: Bladder and Urethra
2.1K
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...

Imaging Studies VI: Voiding Cystourethrography and Cystography
2.6K
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...

Urethra
5.0K
The urethra is a hollowed tubular organ through which urine is expelled from the body. This structure extends from the bladder to the external opening, allowing urine to be released.
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male...

Urologic Endoscopic Procedure: Cystoscopic Examination
4.1K
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Urinary Bladder
3.8K
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...

Urodynamic Studies: Uroflowmetry

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...
