The middle lobe of the prostate causes an elevation in the mucous membrane behind the internal urethral orifice called the uvula of urinary bladder. The uvula can enlarge when the prostate becomes enlarged. The bladder is located below the peritoneal cavity near the pelvic floor and behind the pubic symphysis.
The cystocele, also known as a prolapsed bladder, is a medical condition in which a woman's bladder bulges into her vagina. [ 1 ] [ 5 ] Some may have no symptoms. [ 6 ] Others may have trouble starting urination, urinary incontinence , or frequent urination . [ 1 ]
The trigone (also known as the vesical trigone) [1] is a smooth triangular region of the internal urinary bladder formed by the two ureteric orifices and the internal urethral orifice. The area is very sensitive to expansion and once stretched to a certain degree, stretch receptors in the urinary bladder signal the brain of its need to empty ...
Bladder outlet obstruction (or obstructive uropathy) occurs when urine is unable to flow from the kidneys through the ureters and out of the bladder through the urethra. Decreased flow of urine leads to swelling of the urinary tract, called hydronephrosis. This process of decreased flow of urine through the urinary tract can begin as early as ...
Common findings, determined by ultrasound of the bladder, include a slow rate of flow, intermittent flow, and a large amount of urine retained in the bladder after urination. A normal test result should be 20–25 ml/s peak flow rate. A post-void residual urine greater than 50 ml is a significant amount of urine and increases the potential for ...
Without diagnostic evaluation, the cause of underactive bladder is unclear, as there are multiple possible causes. UAB symptoms can accurately reflect impaired bladder emptying due either to DU or obstruction (normal or large storage volumes, elevated post-void residual volume), or can result from a sense of incomplete emptying of a hypersensitive bladder (small storage volumes, normal or ...
The gallbladder is located on the undersurface of the right lobe of the liver. [9] It produces bile, which is used to help process fats in the body. [9] Humans can live without the gallbladder. [10] The largest lymphatic organ is the spleen, which is dark purple and located under the lower ribs, around the left side of the upper abdomen.
The urethral crest is an anatomical feature present in the urinary system of both males and females.. In males, the urethral crest is known as the crista urethralis masculinae, or the crista phallica, and is a longitudinal fold on the posterior wall of the urethra extending from the uvula of the bladder through the prostatic urethra.
