In human anatomy, men have longer urethras than women. This means that women have bladder infections more often, because their bladders are closer to the outside. Because the male urethra is longer and is not straight, inserting a catheter (tube to help urination) is more difficult in men. In women, the urethra is 2.5-4 cm (1-1.5 in) long. Its opening to the outside of the body is part of the vulva (the area between a womans legs). The female urethra is between the clitoris and the opening to the vagina. In men, the urethra is about 20 cm (8 in) long and its opening to the outside of the body is at the end of the penis. The male urethra has three sections: ...
The urethra is the tube that carries the urine from the bladder to the exterior. The urinary meatus is the external urethral opening. In the male the urethra is common to the urinary and reproductive systems; in the female it belongs only to the urinary system. The female urethra is about 4 cm long, extending from the bladder to the external orifice in the vestibule. It is embedded in the anterior wall of the vagina and surrounded by the sphincter urethrae. The male urethra is about 20 cm long and is divided into three parts: the prostatic, membranous, and penile portions. The prostatic urethra is surrounded by the prostate gland; it contains the orifices of the prostatic and ejaculatory ducts. This portion of the male urethra is about 2.5 cm long. The membranous urethra is about 2 cm in length and is surrounded by the external sphincter. The penile urethra, the longest portion, is about 15 cm long. It lies in the ventral portion of the penis, extending to its external opening. ...
EFFECTS OF DIABETES MELLITUS ON THE BIOMECHANICAL PROPERTIES AND PHARMACOLOGICAL FUNCTION OF THE FEMALE RAT URETHRA EX-VIVO Rachelle Lynn Prantil, MS University of Pittsburgh, 2004 Diabetic cystopathy results in a grossly distended, hypomotile bladder due to inefficient voiding. While the bladder has been extensively studied, little effort has been made towards the understanding of the urethra and the effects of this devastating disease. The current study is aimed to evaluate the effects of diabetes mellitus (DM) on the biomechanical properties and the pharmacological function of the female rat urethra ex vivo. DM was induced in female rats by injection of streptozotocin. At 3, 5,and 10 weeks, the urethras were excised and mounted into an ex-vivo system at in vivo length. For mechanical testing, urethras were subjected to stepwise increases of static, intraurethral pressure from 0 to 20 mmHg in both a baseline and passive state. Continuous outer diameter measurements were made using a laser ...
Purulent discharge from the urethra refers to inflammation of the urethra. Into the urethra to receive pyogenic bacteria. Frequent cause of unprotected sex and infection by the bacterium Neisseria gonorrhoeae. The illness is known as gonorrhea. It is a sexually transmitted disease. Manifested by redness around the mouth of the urethra, pain, cutting (especially when you urinate). Very important is the discharge from the urethra, dirty underwear. When vaginal discharge or similar symptoms should immediately consult a doctor - a man can infect their sexual partners, moreover, untreated gonorrhea can go into a chronic phase, and cause lingering problems - for men it is an inflammation of the prostate and epididymis. In women, inflammation of the cervix.
Figuring out how to insert sounds into the urethra is something that should be left up to the trained professionals. Inserting anything into your urethra just isnt a good idea gentleman. Sounds were created to open up any blockages from the penis through the urethra. Without the usage of these sounds probing their ways to the urethra, the afflicted guy would find it painful if not completely impossible to urinate. Sounds are very thin, smooth, and metallic. Many of them have an s-curve at one end in order for the doctor to tease the blockages open. But, how do you get a sound into the urethra? Very carefully. Thats how.. ...
The urethra is a fibromuscular tube that conducts urine from the bladder (and semen from the ductus deferens) to the exterior. It begins at the neck of the bladder, traverses the pelvic and urogenital diaphragms, and ends at the external urethral orifice. The female urethra, about 4 cm in length, is fused with the anterior wall of the vagina. It ends between the clitoris and the vagina. The male urethra, about 20 cm in length, comprises three parts: prostatic, membranous, and spongy (see figs. 34-1 and 38-4). The prostatic part, which is the most dilatable, descends through the prostate. Its posterior wall presents a median ridge, the urethral crest, the summit of which is termed the colliculus seminalis (or the verumontanum). A diverticulum, the prostatic utricle (probably corresponding to portions of the uterus and vagina) opens on the colliculus, as do the ejaculatory ducts. The prostatic ducts open into a groove, the prostatic sinus, on each side of the urethral crest. The membranous part ...

There is abundant evidence that the lower urinary tract (LUT) mucosal layer is involved both in mechanosensory functions that regulate bladder contractile activity and in urethral sensation. Changes to the mucosa can be associated with a number of bladder pathologies. For example, alterations of the urothelium and underlying lamina propria at both the molecular and structural levels have been reported in both patients and animals associated with disorders such as bladder pain syndrome and diabetic cystopathy. In contrast to the urinary bladder, much less is known about the urothelium/lamina propria of the bladder neck/proximal urethra. There are important gender differences in the outflow region both anatomically and with respect to innervation, hormonal sensitivity, and location of the external urethral sphincter. There is reasonable evidence to support the view that the mucosal signaling pathway in the proximal urethra is important for normal voiding, but it has also been speculated that the ...
In anesthetized rats, voiding is typically associated with phasic activation (bursting) of the external urethral sphincter (EUS). During spontaneous voiding in unanesthetized, unrestrained rats, EUS bursting is the most common form of EUS activity exhibited, but it is not necessary for productive voiding to occur. The aim of the present study was to determine which aspects of EUS activity contributed to void size during bursting and non-bursting voiding in conscious, freely moving rats.. ...
In general, the invention is directed to treatment of urinary incontinence by the implantation of one or more bulking prostheses proximate to a urethral sphincter. These bulking prostheses, which may include biocompatible hydrogel, are implanted into the tissue outside the urethra, proximate to a urethral sphincter. When implanted, the bulking prostheses are in a miniature state. Upon introduction into the body, the devices enter an enlarged state. In their enlarged state, the bulking prostheses supply extra bulk to the tissues proximate to the external urethral sphincter. With the extra bulk, the patient can exercise voluntary control over the external urethral sphincter to close or maintain closure of the urethra and maintain urinary continence.
A method and apparatus for diagnostic evaluation of the urinary tract. The method comprises the steps of generating a urethral pressure profile and simultaneously monitoring and recording electrical signals derived from the urinary tract thereby generating an electrical or electromyographic profile. As fluid is inputted into the urethra the catheter is mechanically withdrawn therefrom at a constant velocity. Fluid pressure within the urethra is derived and recorded thereby providing a urethral pressure profile. Simultaneously, urethral electrical signals derived from one or more electrodes mounted on the catheter are amplified and graphically displayed, thereby plotting urethral electrical activity and urethral fluid pressure at given points along the urethra. The apparatus comprises an interface unit for withdrawing the catheter and for enabling measurement of the various diagnostic parameters.
In the present study, we instilled capsaicin into the uteruses of female rats and found that this procedure induces cross-organ sensitization on the pelvic-urethra reflex activity as well as the physiological target of this reflex, the contraction wave of the urethra, with a parallel increase in the phosphorylated NMDA NR2B subunit level in the spinal dorsal horn. Moreover, pharmacological blockage of the TRPV1 receptor attenuates the reflex potentiation caused by uterine capsaicin instillation as well as the increment in the phosphorylated NR2B subunit level, indicating that TRPV1 plays a role in the spinal NR2B subunit-dependent cross-organ sensitization induced by uterine capsaicin instillation.. Pelvic pain syndrome, one of the most frequent disorders in women, can lead to years of suffering, disability, and numerous unsuccessful medical treatments. Pelvic pain can arise from several sources, such as the gastrointestinal, urinary, genital, muscular, and skeletal systems. The ...

The bladder and urethra are supported by muscles, ligaments, and connective tissues around the base of the bladder. This support prevents the leakage of urine, along with the watertight seal provided by the urethra. As a result of pregnancy, childbirth, and aging, or damage by scarring from surgery or radiotherapy, these structures may become damaged or weakened, thus causing stress incontinence, meaning an involuntary loss of urine that occurs during physical activity such as coughing, sneezing, laughing, or exercise . The injection of bulking agents such as collagen around the urethra aims to improve the lost support of the bladder and urethra. The substance most commonly used for injection is collagen; other bulking agents are being developed, for example, a silicon base suspended in a viscous gel called Macroplastique. Teflon paste, introduced in the 1970s, initially gave good results, but was discontinued after reported problems with excessive scarring and with the migration of Teflon ...
Your bladder is a stretchy storage sac for pee. How stretchy? Well, a bladder that is fairly full can hold about 500 ml (1 pint), but it can still stretch to nearly twice that volume (think about the size of a 1 liter water bottle). Near the bottom of your bladder is a tube to the outside of your body called the urethra (yur-ee-thra). In males the urethra passes through the penis and in women it opens to the outside just above the vagina. You have two circular valves or sphincters that normally keep the urethra pinched off when urine is not passing through. The internal urethral sphincter is closer to the bladder and is controlled by reflexes in your spine and other parts of your nervous system that you cannot consciously control. The external urethra sphincter is under conscious control, so you can "tell" it to open and close as needed.. When your bladder fills, it stretches and nerves fire in response to this stretch and activate a spinal reflex. Usually, you feel the need to pee before urine ...

Stress incontinence occurs when the pressure inside your bladder as it fills with urine becomes greater than the strength of your urethra to stay closed. The urethra is the tube urine passes through out of your body. Any sudden extra pressure on your bladder, such as laughing or sneezing, can then cause urine to leak out of your urethra.. Your urethra may not be able to stay closed if the muscles in your pelvis (pelvic floor muscles) are weak or damaged, or your urethral sphincter - the ring of muscle that keeps the urethra closed - is damaged.. These problems may be caused by: ...

An endourethral device is provided having an elongate member having proximal and distal segments, the elongate member positionable within a lower urinary tract so as to at least partially traverses a prostatic urethra. A proximal anchor, adapted to abuttingly engage portions of a bladder neck so as to at least proximally anchor the device, is supported at least indirectly by the proximal segment of said elongate member. The proximal anchor includes bladder engaging elements radially extending from the proximal segment of said elongate member, urine being freely dischargable about at least the proximal segment so as to substantially bathe the bladder neck therewith.
The present method involves the use of a urethral probe, having one tapered end with a silk thread anchored near said tapered end, at about four centimeters from the apex of the taper. The probe is inserted into the urethra while the free end of the thread is held firmly in the examiners hand. Once the probe has been inserted into the urethra to the point where the attachment of the string is exactly at the external meatus, the examiner holds only the thread, exerting a slight tension on it. (The thread represents a continuation of the unstrained urethral axis.) The patient is then asked to strain. If there is any weakness of urethral support, the instrument is deflected upward. This upward deflection causes the stationary thread to create an angle which is then read directly from a scale, wherein the degree of deflection can be interpretively read in order to determine the degree of deformity of the urethrovesical angle from its normal anatomic position.

The contractile and inhibitory effects of pollen extracts on bladder and urethral smooth muscle strips from mice and domestic pigs were investigated. In the mice bladder strips, T-60 (a water-soluble extract), GBX (an acetone-soluble extract), and CN (consisting of both T-60 and GBX at a ratio of 20:1) induced contractions at 0.1-3.0 mg/ml in a concentration-dependent manner. CN, T-60, and GBX (3.0 mg/ml) attained 27.6, 27.0, and 7.3% of the ACh response (10.0 microg/ml). The T-60 effect was antagonized noncompetitively by atropine (0.029-0.29 ng/ml). CN, T-60, and GBX inhibited noradrenaline (NA)-contracted urethral strips of mice (IC (50) values for NA 0.3 microg/ml: 0.508, 0.553, and 0.888 mg/ml, and for NA 10.0 microg/ml : 0.556, 0.705, and 0.673 mg/ml). Only GBX relaxed the normal tone of pig urethral strips. The water-soluble extract of corn ( ZEA MAYS) pollen, the main pollen of CN, contracted the mice bladder strips and inhibited NA-contracted urethral strips of mice more potently than ...

The author of this blog is clearly not a biochemist. Life depends on molecules, and a drug has already proven to be far superior to efforts at tissue engineering.. Theres a big difference between a urethra, which has only one or two cell types, and an entire kidney, which has hundreds, put together in the most intricate way, which we still dont understand. Its roughly the difference between your driveway and your house: building one doesnt mean you have a clue how to build the other. Its fair to say that we wont be printing kidneys any time soon.. On the other hand, my paper showing how to prevent 90% of kidney failure just by popping the right dose of the right pill was published in 2002. If it had gotten the slightest media attention, there would be no waiting list now for cadaver kidneys; thered be more than enough kidneys for the relatively few kidney patients who still needed them. No living donors would be necessary. And money wouldnt be wasted on trying to print kidneys.. Indeed, ...

UI is usually caused by problems with muscles and nerves that help to hold or pass urine.. Urine is stored in the bladder. It leaves the body through a tube that is connected to the bladder called the urethra. Look at the images below to see how this process works.. Muscles in the wall of the bladder contract to force urine out through the urethra. At the same time, sphincter (ss-FINK-ter) muscles around the urethra relax to let the urine pass out of the body.. Incontinence happens if the bladder muscles suddenly contract or the sphincter muscles are not strong enough to hold back urine.. UI is twice as common in women as in men. Pregnancy, childbirth, and menopause are major reasons why. But both women and men can become incontinent from brain injury, birth defects, stroke, diabetes, multiple sclerosis, and physical changes associated with aging.. ...
