Abstract:
Describing a "high bladder neck" is common practice, yet it is not a standardized entity, and it lacks an evidence base in diagnostics and therapy. Recent systematic reviews report few trials, yet incision of the bladder neck remains a first-line therapy. The concept insinuates a basis for bladder outlet obstruction, so it is during voiding that such an issue should be assessed. For cystourethroscopy, the urinary tract is in the storage phase. A pressure-flow study in videourodynamics can visualize when the bladder neck is deflected into the proximal prostatic urethra by the force of bladder contraction, but this is rarely undertaken. Standard urodynamics may infer this diagnosis, but only by assuming the cause. Other forms of imaging are being evaluated, though they remain remote from delivering evidence based on therapy outcomes. Proper consensus regarding the "high bladder neck" is needed, primarily for standardization of terminology and agreement on justifiable endoscopic and imaging approaches.

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
