概括
使用症状和尿道流量计的新型非侵入性模型可以帮助区分排尿器低活性 (DU) 与膀出口阻塞 (BOO) 在患有下泌尿道症状 (LUTS) 的女性中. 这种工具有助于在没有侵入性测试的情况下区分这些常见的排泄功能障碍.

- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 妇科 妇科医生 妇科
- 医学诊断 医学诊断 医学诊断
背景情况:
- 排尿器低活性 (DU) 和膀出口阻塞 (BOO) 是导致下尿道症状 (LUTS) 的女性排尿功能障碍的主要原因.
- 区分DU和BOO在临床上具有挑战性,因为症状重叠,需要进行侵入性泌尿动力学研究 (UDS).
- 开发非侵入性诊断工具对于有效的LUTS门诊管理至关重要.
研究的目的:

01:23Urinary Bladder
502
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...

01:26The Micturition Reflex
516
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...
