The wall of the urinary bladder of a fetal pig is a sack like organ located by the umbilical cord. When relaxed the walls appear to be folded.
The urinary bladder is a muscular organ for storing urine. The urinary bladder wall is stretchable to accommodate varying volumes of urine.
The rugae in the wall of the urinary bladder are folds that allow the bladder to expand and contract as it fills and empties with urine. When the bladder fills, the rugae flatten, providing increased surface area for storage. This elasticity is crucial for accommodating varying volumes of urine without damaging the bladder wall.
The bundles of interlaced muscular fibers in the wall of the urinary bladder comprise the internal urethral sphincter. The contraction of the internal urethral sphincter prevent the bladder from emptying until the urinary pressure reaches a certain level.

The bladder needs to be a muscular sac to store and effectively expel urine. The muscles in the bladder wall contract to push urine out of the body during urination, and they also relax to allow the bladder to stretch as it fills with urine.
detrusor muscle
Specialized cells called transitional cells form the lining of the urinary bladder.
A hernia of the urinary bladder is called a "cystocele." It occurs when the bladder protrudes into the front wall of the vagina due to weakened pelvic support tissues. This condition can lead to symptoms such as urinary incontinence or difficulty in urination. Treatment often involves pelvic floor exercises or surgical intervention, depending on severity.
A urinary diversion is created as a means to treat cancer of the bladder, when conservative measures have been unsuccessful, or when there is recurrence of the disease invading the muscle wall.
The wall of the urinary bladder should not be > 3 mm thick when distended and not > 5 mm thick when decompressed. The thickened wall could be due to the edema (swelling) of the wall which can happen due to the inflammation(cystitis) or the thickening could be due to the deposition of urinary sediments on the walls of the bladder. These are the 2 commonest causes. Bladder cancer is another cause. Generally if you are diagnosed with thickening of the bladder you will be sent to a urologist and have a cystoscopy performed.
