概括
在前列腺的holmium激光核化 (HoLEP) 过程中,外泌尿道 (EUS) 上的辐射力会导致扩张,导致压力尿失禁 (SUI). 这种辐射力机制解释了HoLEP后的SUI及其时间.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 手术创新 在外科创新.
- 下尿道的症状 下尿道的症状
背景情况:
- 压力尿失禁 (SUI) 是前列腺的霍尔激光取核 (HoLEP) 后的一个常见并发症.
- 传统的解释涉及外部尿道 (EUS) 的纵向过度拉伸.
- 提出了一种新的机制,涉及到EUS的辐射力.
研究的目的:
- 调查对EUS施加的极端辐射力,作为HoLEP SUI后的新机制.
- 评估切除镜角度,EUS扩张和SUI发生率之间的关系.
主要方法:
- 在 HoLEP 期间使用手术内图像评估了切除镜角度.
- 进行光学校准测量和对EUS扩张的三角形计算.
- 在HoLEP后一个月使用手术前MRI研究 (n=55) 验证了针对SUI的三角形公式.
主要成果:
- 与非SUI组 (54°) 相比,SUI组的最大中间切除镜角度显著更高 (57°).
- 计算的EUS扩张在SUI组 (49mm) 与非SUI组 (39mm) 中显著增加.
- EUS扩张和切除镜角是HoLEP后SUI的独立预测因素,在预测准确度方面表现优于前列腺体积和患者年龄 (AUC 0.849).
结论:
- 在切除镜角化过程中由辐射力引起的EUS扩张是后HoLEP SUI的合理原因.
- 这种机制也可能解释HoLEP后SUI的时间模式.
- 这些发现表明,在HoLEP之后,人们对SUI病因有了新的理解,这可能有助于指导手术技术的修改.

Anatomy of the Genitourinary System II: Bladder and Urethra
1.2K
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...

Physiology of the Genitourinary System II: Tubular Reabsorption and Secretion
934
The kidneys maintain homeostasis through filtration, reabsorption, and secretion. Tubular reabsorption and secretion are crucial in forming urine and regulating electrolytes, water balance, and waste elimination.Tubular Reabsorption and Secretion ProcessesTubular reabsorption is the process that reclaims essential substances such as electrolytes, glucose, amino acids, and water from the glomerular filtrate back into the bloodstream. This is achieved through passive and active transport...

Urinary Tract Calculi I: Introduction
381
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations
353
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

Urodynamic Studies: Uroflowmetry
3.1K
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...

Urinary Bladder
3.0K
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...
