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.
Because it measures the thickness of the bladder wall, it is useful in cases of recurrent Urinary tract infections. [13] One study found that, in contrast to simple recurrent UTIs, which typically have a bladder wall thickness of less than 3 mm, cystitis cystica is indicated by values of bladder wall thickness greater than 3 mm. [14]
Sim subsequently developed another procedure that did not require the full-thickness dissection of the vaginal wall. In 1888, another method of treating anterior vaginal wall Manchester combined an anterior vaginal wall repair with an amputation of the cervix and a perineorrhaphy. In 1909, White noted the high rate of recurrence of cystocele ...

Cystoscopy has similar indications in animals, including visualisation and biopsy of mucosa, retrieval or destruction of urinary bladder stones and diagnosis of ectopic ureters. [9] [10] [11] In turtle and tortoises, cystoscopy has additional value as it permits the visualisation of internal organs due to the thin urinary bladder wall. [12]
The drug Elmiron helps, for some patients, to prevent the formation of Hunner's ulcers by coating the bladder wall, thus making it harder for the acid in urine to irritate the bladder wall lining, which can lead to ulceration. Elmiron is a controversial medication within the interstitial cystitis community, with its efficacy questioned by many.
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 ...
