Diagnosis of female bladder outlet obstruction
and relevance of the parameter area under the curve of detrusor pressure during voiding: preliminary results.
The effects and challenges of bladder outlet obstruction
Voiding urethrogram reveals well filled proximal urethra is consistent with viding pressure flow study; both indicate no clinically relevant bladder outlet obstruction
despite prostatic enlargement noted on digital rectal examination.
The evolution of obstruction-induced overactive bladder symptoms following urethrolysis for female bladder outlet obstruction
While they found a high prevalence of lower urinary tract dysfunction, including bladder outlet obstruction
in 51% and detrusor overactivity in 68%, removal of the stone did not significantly change urodynamic findings, raising the question of whether their presence should necessarily lead to discontinuation of evaluation prior to treatment.
2) stricture SD: standard deviation; TOV: trial of voiding; UTI: urinary tract infection; BOO: bladder outlet obstruction
Early diagnosis of fetal bladder outlet obstruction
Figures 1A and 1B compare an X-Y plot in a normal male with normal voiding function to a male patient with severe bladder outlet obstruction
associated with benign prostatic enlargement.
Partial bladder outlet obstruction
(pBOO) is a ubiquitous problem i n urology, affecti ng the fetus with posterior urethral valves, the child with spina bifida, the young adult with a urethral stricture, and the elderly male with prostatic hypertrophy.
Reynard, Lim, Swami, and Abrams (1996) compared the effect of 8-French catheters versus no catheters in a group of 59 men with varying degrees of bladder outlet obstruction
and found no statistically significant results when the Qmax rates were compared.
5] Occasionally, edema causes bladder outlet obstruction
and urinary retention.
In small or moderate stones, endoscopic procedures such as optical mechanical cyst lithotripsy have an added advantage as it can be combined with corrective procedure for the cause of bladder outlet obstruction
A cysto-urethroscopy was also performed to evaluate the lower urinary tract for anatomic bladder outlet obstruction
or any abnormal bladder pathology.
In a placebo-controlled trial of 200 men with symptoms of LUTS and bladder outlet obstruction
, 12 weeks of treatment with mirabegron did not adversely affect voiding parameters on urodynamics, including maximum urinary flow and detrusor pressure at maximum urinary flow, when compared with placebo.
Cystoscopy may be required to evaluate bladder outlet obstruction
if the patient is not voiding.
