The detrusor muscle is able to change its length. It can also contract for a long time whilst voiding, and it stays relaxed whilst the bladder is filling. [9] The wall of the urinary bladder is normally 3–5 mm thick. [10] When well distended, the wall is normally less than 3 mm.
On CT or MRI imaging, it appears as a sac-like outpouching. If the diverticulum is filled with contrast agents, the wall would be thin and may contain air, fluid, contrast material, or food debris. If the food debris is broken down by bacteria, the outpouching may show "faeces sign". Inflammation of the duodenal wall shows thickening of the wall.
Features that suggest posterior urethral valves are bilateral hydronephrosis, a thickened bladder wall with thickened smooth muscle trabeculations, and bladder diverticula. [citation needed] Voiding cystourethrogram (VCUG) is more specific for the diagnosis. Normal plicae circularis are variable in appearance and often not seen on normal VCUGs.
Neurogenic bladder dysfunction, often called by the shortened term neurogenic bladder, refers to urinary bladder problems due to disease or injury of the central nervous system or peripheral nerves involved in the control of urination. [1] [2] There are multiple types of neurogenic bladder depending on the underlying cause and the symptoms.
It can detect lesions in the bladder that are large enough to be seen, gauge the thickness of the bladder wall, and look for additional lesions that might be the source of hematuria. Cystitis cystica can show up on a CT urogram as a number of small, rounded filling defects in the bladder wall that range in size from 2 to 5 mm. Lesions can also ...
Ultrasound findings may show thickened gall bladder wall, tiny anechoic spaces (Rokitansky–Aschoff sinuses or RAS), and twinkling artifact (or comet-tail reverberation). Comet tail reverberation, which is due to reflections from cholesterol crystals, is a highly specific sign for adenomyomatosis.
Treatment, depending on cause, may require prompt drainage of the bladder via catheterization, medical instrumentation, surgery (e.g., endoscopy, lithotripsy), hormonal therapy, or a combination of these modalities. [citation needed] Treatment of the obstruction at the level of the ureter: Open surgery. Less invasive treatment: laparoscopic ...
Gas in the bladder wall will often have the appearance of cobblestone or a “beaded necklace” with the use of conventional radiography. [7] Delayed diagnosis can lead to a severe infection, extension of the uterus, rupturing of the bladder, and death. Emphysematous cystitis has an overall mortality rate of 7%.
