Summary
Urine stream interruption exercise increases post-void residual volume, leading to less efficient micturition. This technique should not be incorporated into current pelvic floor muscle training practices.
Area of Science:
- Urology
- Pelvic Floor Physical Therapy
Background:
- Micturition is a complex process involving bladder muscle contraction and sphincter relaxation.
- Pelvic floor muscle training is a common approach for managing various urinary disorders.
Purpose of the Study:
- To evaluate the impact of a urine stream interruption exercise on the efficiency of micturition in women.
Main Methods:
- Prospective study involving 20 female patients without urinary disorders.
- Two uroflowmetry tests were conducted: one for standard micturition and one involving a urine stream interruption exercise.
- The exercise required participants to interrupt and restart voiding multiple times during a single micturition event.
Main Results:
- Urine stream interruption significantly increased post-void residual volume compared to standard micturition (36.7 mL vs 8.2 mL, P=0.02).
- Maximal flow rate was lower during the interruption exercise (17.8 mL/min) than during normal voiding (26.9 mL/min, P<0.0001).
- Flow rate and maximal flow rate per voiding sequence decreased progressively during the interruption exercise.
Conclusions:
- The urine stream interruption exercise results in less efficient voiding and higher residual urine volumes.
- This exercise is not recommended for use in current pelvic floor muscle training protocols.

01:26The Micturition Reflex
2.5K
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...

01:32Filtration and Urine Formation
53.3K
The function of the kidneys is to filter, reabsorb, secrete, and excrete. Every day the kidneys filter nearly 180 liters of blood, initially removing water and solutes but ultimately returning nearly all filtrates into circulation with the help of osmoregulatory hormones. This process removes wastes and toxins but is also crucial to maintain water and electrolyte levels. Most of these functions are performed by the tiny but numerous nephrons contained within the kidneys.

In two-dimensional incompressible fluid flow, the continuity equation is essential for ensuring mass conservation, meaning that any change in fluid entering or exiting a region is balanced by a corresponding change elsewhere. For incompressible flow, where density remains constant, this requirement simplifies to the condition that the divergence of the velocity field must be zero. Mathematically, this is expressed as,

A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...

10:38A Cognitive Paradigm to Investigate Interference in Working Memory by Distractions and Interruptions

A novel cognitive paradigm is developed to elucidate behavioral and neural correlates of interference by to-be-ignored distractors versus interference by to-be-attended interruptors during a working memory task. In this manuscript, several variants of this paradigm are detailed, and data obtained with this paradigm in younger/older adult participants is...
