Cystography and Radiology


Tentative Diagnosis

Acute cystitis- evidence of pyuriaHypersensitive bladder – small voided volume & nor

mal flow patternDetrusor overactivity – urge incontinenceBladder outlet obstruction- low flow rate, obstructiv

e flow pattern, residual urinePelvic floor hypertonicity – intermittent flow Interstitial cystitis – lower abdominal pain at a full bl

adderProlapse and pelvic floor relaxation


Urodynamic Study

UroflowmetryCystometry Urethral sphincter EMGUrethral pressure profilometryPressure flow multi-channel studyVideourodynamic studyResidual urine volume


Differential Diagnosis based on Lower urinary tract symptoms

Hypersensitive bladder – normal flow rateOveractive bladder – presence of DIContracted bladder – low bladder complianceSpastic urethral sphincter – low flow rate, large r

esidual urine, poor relaxed sphincter EMG Interstitial cystitis – lower abdominal pain at full

bladder, small capacity, low compliance, positive KCl test

Differential Diagnosis by Qmax

A normal Qmax excludes most of bladder outlet obstruction

A low flow rate cannot differentiate BOO from low detrusor contractility

Women with hypersensitive bladder and DI often have a low Qmax

Residual urine measurement is important


Uroflowmetry – Normal flow


Uroflowmetry – Low contractility


Uroflowmetry – Obstructive flow


Uroflowmetry – Straining flow


Pressure flow study & Videourodynamic study

The most accurate diagnosis for female frequency urgency syndrome

Direct visualization of bladder outlet during filling and voiding phases

Leak-point pressure measurementProvide fruitful lower urinary tract

information

Female Bladder Outlet Obstruction

6-9% in the women with LUTS refractory to medication

Difficult to be diagnosed due to lack of diagnostic criteria

Image study is necessary in addition to pressure flow results

Cystscopy is not always conclusive

Botulinum Toxin injections

Injection to detrusor muscle – for detrusor hyperreflexia & instability

Periurethral injection- DESD, dysfunctional voiding, poor relaxation of urethral sphincter

Subtrigonal injection- for IC(?) or refractory DI (?)
