Abstract
Overactive bladder is a symptom complex that includes urinary urgency with or without urge incontinence, urinary frequency (voiding eight or more times in a 24-hour period), and nocturia (awakening two or more times at night to void). The International Continence Society classified overactive bladder as a syndrome for which no precise cause has been identified, with local abnormalities ruled out by diagnostic evaluation.
Clinical assessment including history and physical examination has been shown to be an ineffective way of assessing women with lower urinary tract dysfunction.
Urodynamics have long been the only option, and still remain the gold standard, for examining people with OAB complaints and composing an appropriate treatment plan.
Alternatives for this invasive, expensive, and time consuming examination have been explored. Bladder wall thickness (BWT) has been suggested as a more objective and easier measurement that potentially could diagnose OAB and be used to analyse treatment response.
This case-control study was done at Ain shams university maternity Hospital during the period between January 2007 and June 2009.
One hundred (100) patients were included in the study and were divided into study group (50 patients diagnosed as OAB by urodynamics) and Control group (50 patients diagnosed as SUI by urodynamics).
There was significant negative correlation between cystometric capacity and (trigone, dome, mean thickness of the three sites) and highly negative correlation for the mean of the anterior wall in the study group.
There was significant positive correlation between detrosur pressure and the anterior wall thickness, highly positive correlation between detrosur pressure and the trigone, dome, mean of the three sites in the study group.
As regard maximum flow rate it was significantly positive correlated to (dome, mean thickness of the three sites), highly significant correlated to trigone in the study group.
We found that the best cutoff value for the mean BWT was 4.78mm with 90% sensitivity and 78% specificity.
