Issue doi: This strategy can be used to assess voiding dysfunction and treatment efficacy in various mouse models of lower urinary tract calcoli nella prostata e nella vescica korea 2016 LUTD. Liu, T. The incidence of clinical benign prostatic hyperplasia BPH and lower urinary tract symptoms LUTS is increasing due to the aging population, resulting in a significant economic and quality of life burden.
Transgenic and other mouse models have been developed to recreate various calcoli nella prostata e nella vescica korea 2016 of this multifactorial disease; however, methods to accurately quantitate urinary dysfunction and the effectiveness of new therapeutic options are lacking.
Here, we describe a method that can be used to measure bladder volume and detrusor wall thickness, urinary velocity, void volume and void duration, and urethral diameter. This would allow for the evaluation of disease progression and treatment efficacy over time.
Mice were anesthetized with isoflurane, and the bladder was visualized by ultrasound. For non-contrast imaging, a 3D image was taken of the bladder to calculate volume and evaluate shape; the bladder wall thickness was measured from this image.
Disfunzione sessuale post-operatoria s prostatectomia radicale
For contrast-enhanced imaging, a catheter was placed through the dome of the bladder using a gauge needle connected to a syringe by PE50 tubing.
A bolus of 0. Urethral diameter was determined at the point of the Doppler velocity sample window during the first voiding event. Velocity was measured for each subsequent event yielding a flow rate. In conclusion, high frequency ultrasound proved to be an effective method for assessing bladder and urethral measurements during urinary function in mice.
Although the development of BPH is generally associated with aging, other factors including obesity and metabolic syndrome can lead to Calcoli nella prostata e nella vescica korea 2016 in relatively younger men 34.
Come testare la bph e la prostatite
Many men with BPH develop lower urinary tract symptoms LUTS that significantly decrease their quality of life, click to see more some experience complications that may include bleeding, infection, bladder outlet obstruction BOObladder stones, and renal failure. Better disease models, murine and other, to allow the accurate study of the effects of varied causative and therapeutic factors in this disease process over time is highly desirable 9.
Rodent models have been extensively used to study urodynamics; however, most studies are focused on female micturition and disease In order to fully examine all aspects of male See more, rodent models have been developed and used to study different aspects of BPH including changes in cellular proliferation, smooth muscle function, collagen calcoli nella prostata e nella vescica korea 2016, and inflammation 111213 However, rodent and human prostate anatomy differ.
While the human prostate is compact and encased by a condensed fibromuscular layer, the rodent prostate is lobular; click these differences complicate direct comparisons of disease progression and treatment efficacy.
Additionally, LUTS are difficult to assess in mice, since it is not possible to directly measure bother. Instead, current methods for studying disease correlate histological features with physiological features i. Physiological features are frequently evaluated as post-mortem necropsy endpoints, and there is an inability within the same animal to observe BOO across time. Recently, we have identified a subdivision of the pelvic urethra the prostatic urethra where exogenous hormone implants cause a narrowing based on post-mortem necropsy assessments Current methods do not allow for the direct, in vivo assessment of urethral narrowing during voiding.
Ultrasound is a non-invasive diagnostic and evaluation technique that has successfully been used in other disease models. It is used to quantify organ volume and assess vascular flow 1920 Ultrasound is also used to calcoli nella prostata e nella vescica korea 2016 and guide microinjections, allowing for targeted injections of stem cells or other drugs, and to evaluate systolic and diastolic cardiac function. This protocol describes the use of high frequency ultrasound to evaluate lower urinary tract anatomy and assess urinary physiology in anesthetized mice.
We describe the use of ultrasound for measuring bladder volume and wall thickness. We also describe the more info of contrast-enhanced ultrasound to measure urine velocity, urine volume, void duration, and urethra diameter.
The use of ultrasound calcoli nella prostata e nella vescica korea 2016 a more comprehensive understanding of the lower urinary tract in vivo, determines how disease alters normal voiding function, and gives us the tools to better evaluate the effectiveness of new therapeutic options. Currently, the non-contrast imaging calcoli nella prostata e nella vescica korea 2016 is non-terminal, while the current contrast-enhanced imaging protocol is a terminal procedure.

Ultrasound can be used with or without contrast enhancement depending on the experimental design and endpoint measurement. Mice are anesthetized with isoflurane and shaved and all traces of hair removed with a depilatory cream. Anesthetized animals are placed on a heated platform with the ultrasound probe positioned along the long axis of the bladder Figure 1.
Figure 2 shows representative ultrasound images of a mouse bladder acquired without contrast agent. The bladder wall is hyperechoic whiteand the bladder wall thickness is measured using a software measurement package. A bladder surface projection can be rendered to determine bladder volume, wall thickness, and wall volume Table 1.
For contrast enhanced bladder and lower urinary tract imaging, a catheter must be inserted into the bladder and microbubbles injected. Figure 3 shows a representative image of a microbubble-filled bladder. The bladder is hyperechoic appears white in the image.
A low frequency ultrasonic burst destroys the bubbles and the bladder becomes transiently hypoechoic appears blackbefore the bubbles reform, confirming this structure as the bladder. A bolus of microbubbles 0.
The urethra is confirmed by applying a low frequency ultrasonic burst during the urination event and observing destruction and reformation of microbubbles. Several measurements can be made during the urination event. The urethral lumen diameter can be acquired pre- and post-urination along with the flow velocity of urine passing calcoli nella prostata e nella vescica korea 2016 that region of the urethra and total outflow Figure 4.
Using contrast imaging, measurements were made through the entire length of the urethra Table 2. From these measurements, further calculations are made to examine urinary flow and bladder compliance Table 3.

Calculations and formulas applicable to ultrasound measurements to assess bladder function and urinary flow. Current techniques for evaluating the lower urinary tract of rodents are limited by their ability calcoli nella prostata e nella vescica korea 2016 directly correlate changes in voiding physiology with changes in prostatic histology consequent to disease progression.
Void spot assays and uroflowmetry can be used to assess spontaneous urination events in rodents, and these techniques can be used to evaluate changes over a period of time 1516 However, for both techniques, bladder fullness cannot be assessed prior to the start of the test.
Additionally, changes in urination may occur due to behavior rather than a direct result of disease progression, making it difficult to determine the impact of disease on urination. Cystometry, another technique for evaluating bladder dysfunction in rodents, can provide an in vivo assessment here bladder function However, the dynamic effect of the rodent prostate on voiding function is not clear.
Previous studies have documented mouse urethral histological changes in mice associated with altered voiding function
