- Determining a post-void residual (PVR) is an integral part of assessing bladder volume in patients with suspected urinary retention and in distinguishing among the three most common conditions seen in nursing home residents: urinary incontinence, urinary retention and urinary tract infections.

Picture of the Bladder © 2014 WebMD, LLC. All rights reserved. The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear.Urine is made in the kidneys, and travels down two tubes called ureters to the bladder. The bladder stores urine, allowing urination to be infrequent and voluntary. The bladder is lined by layers of muscle tissue that stretch to accommodate urine.he normal capacity of the bladder is 400 to 600 mL. During urination, the bladder muscles contract, and two sphincters (valves) open to allow urine to flow out. Urine exits the bladder into the urethra, which carries urine out of the body.

The Kidneys and Urinary Tract The urinary tract is a series of tubes and storage vessels that take the urine produced by the kidneys from inside the body to the outside. This includes the ureters, bladder and urethra. The ureters take urine produced by the kidneys to the bladder. The bladder stores urine until it is ready to be passed out. The urethra forms the passage between the bladder and the outside world. In men, the urethra also carries sperm.

Vesicoureteral Reflux Vesicoureteral reflux is the abnormal flow of urine from the bladder to the upper urinary tract. The urinary tract is the body’s drainage system for removing wastes and extra water. The urinary tract includes two kidneys, two ureters, a bladder, and a urethra. Blood flows through the kidneys, and the kidneys filter out wastes and extra water, making urine. The urine travels down two narrow tubes called the ureters.

Urinary Bladder 1 The muscularis is commonly referred to as the detrusor muscle and contracts during urination to expel urine from the body. 2  The muscularis also forms the internal urethral sphincter, a ring of muscle that surrounds the urethral opening and holds urine in the urinary bladde.rine produced by the kidneys flows through the ureters to the urinary bladder, where is it stored before passing into the urethra and exiting the body.

Bladder (Urinary), Anatomy, Location, Parts and Pictures the urinary bladder is a hollow muscular organ located in the lesser pelvis when empty it serves as a reservoir for urine and can stretch considerably to store close to a maximum of 500 milliliters of urine the average full bladder that is not overly distended contains about 350 milliliters of urine

urinary bladder urinary bladder. a distensible reservoir with muscular walls and a lining mucous membrane that lies in the ventral part of the pelvic cavity or abdomen (especially far forwards in the cat). It receives urine from the kidneys via the ureters and discharges urine to the exterior of the body via the urethra.

- The post-void residual (PVR) urine test measures the amount of urine left in the bladder after urination. The test is used to help evaluate: Incontinence (accidental release of urine) in women and men. Urination problems. An enlarged prostate (benign prostatic hyperplasia, or BPH).

Urethral sphincters The  urethral sphincters are two muscles used to control the exit of urine in the urinary bladder through the urethra. The two muscles are either the male or female external urethral sphincter and the internal urethral sphincter. When either of these muscles contracts, the urethra is sealed shut.

- Points to Remember. 1  Vesicoureteral reflux (VUR) is the abnormal flow of urine from the bladder to the upper urinary tract. 2  VUR is more common in infants and young children, but older children and even adults can be affected. 3  In many cases, a child with VUR has no symptoms.

What are urinary catheters? A urinary catheter is a hollow, partially flexible tube that collects urine from the bladder and leads to a drainage bag. Urinary catheters come in many sizes and types. They can be made of: rubber; plastic (PVC) silicone; Catheters are generally necessary when someone can’t empty their bladder.

Children's (Pediatric) Voiding Cystourethrogram A children's (pediatric) voiding cystourethrogram (VCUG) is an x-ray examination of a child's bladder. and urinary tract that uses a special form of x-ray called fluoroscopy and a contrast material. An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical. conditions.

urinary bladder urinary bladder. The urinary bladder is a temporary storage reservoir for urine. It is located in the pelvic cavity (see pelvis), posterior to the symphysis pubis, and below the parietal peritoneum. The size and shape of the urinary bladder varies with the amount of urine it contains and with pressure it receives from surrounding organs.

Vesicoureteral Reflux (VUR) There are two types of cystogram that are used in the diagnosis of vesicoureteral reflux. 1  Voiding cystourethrogram (VCUG) – This is an imaging test that uses X-ray technology to view the urinary tract. Using a contrast dye, the technician will fill the bladder using a urinary catheter and will take X-ray images.

Urinary bladder Urinary bladder. The urinary bladder is a hollow muscular organ in many animals, that collects and stores urine from the kidneys before disposal by urination. In the human the bladder is a hollow muscular, and distensible (or elastic) organ, that sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra. The typical human bladder will hold between 300 and 500 mL (10.14 and 16.91 fl oz) before the urge to empty occurs, but can hold considerably more.

Urodynamic Testing The lower urinary tract includes the bladder, a balloon-shaped muscle that stores urine, and the urethra, a tube that carries urine from the bladder to the outside of the body during urination. If the urinary system is healthy, the bladder can hold up to 16 ounces—2 cups—of urine comfortably for 2 to 5 hours.

Difference between Human and Frog The urinary bladder is a sac-like hollow organ used for the storage of urine. The urinary bladder is located along the body’s midline at the inferior end of the pelvis. Urine entering the urinary bladder from the ureters slowly fills the hollow space of the bladder and stretches its elastic walls.

Urinary bladder Detrusor muscle. The detrusor muscle is a layer of the urinary bladder wall made of smooth muscle fibers arranged in spiral, longitudinal, and circular bundles. When the bladder is stretched, this signals the parasympathetic nervous system to contract the detrusor muscle. This encourages the bladder to expel urine through the urethra.

- The bladder, also known as the urinary bladder, is an expandable muscular sac that stores urine before it is excreted out of the body through the urethra. It is located in the lower abdominal area near the pelvic bones.Read More.he bladder, like the stomach, is an expandable saclike organ that contracts when it is empty. The inner lining of the bladder tucks into the folds and expands out to accommodate liquid. When empty, the bladder’s muscle wall becomes thicker and the entire bladder becomes firm.

Urethral sphincters The urethral sphincter is one of two muscles used to control the exit of urine in the urinary bladder through the urethra. The two muscles are the male or female external urethral sphincter and the internal urethral sphincter. When either of these muscles contracts, the urethra is sealed shut. The external urethral sphincter originates at the ischiopubic ramus and inserts into the intermeshing muscle fibers from the other side. It is controlled by the deep perineal branch of the pudendal nerve.

Urinary Bladder The surface of the lateral and inferior sides of the urinary bladder forms a layer of loose connective tissue known as the adventitia. The adventitia loosely connects the urinary bladder to the surrounding tissues of the pelvis. The urinary bladder functions as a storage vessel for urine to delay the frequency of urination. It is one of the most elastic organs of the body and is able to increase its volume greatly to accommodate between 600 to 800 ml of urine at maximum capacity.
