Endoscopy and Radiology for Lower Urinary Tract Dysfunction Hann-Chorng Kuo Department of Urology Buddhist Tzu Chi General Hospital
Lower Urinary Tract • Urinary bladder • Ureteral orifices • Trigone • Bladder neck • Prostate and prostatic urethra • Urethral sphincter • Urethra (posterior, bulbous, anterior)
Bladder wall in Cystoscopy • Smooth bladder wall • Trabeculated bladder wall • Diverticulum • Pseudodiverticulum • Bladder tumor • External compression
Bladder mucosa • Normal mucosa and vasculature • Hyperemia • Ischemia • Hemorrhagic cystitis • Cystitis cystica • Pseudomembranous trigonitis • Granulomatous cystitis
Prostatic enlargement • Benign prostatic enlargement • Prostatic cancer
Urethral Stricture • Bladder neck contracture • Membranous urethral stricture • Anterior urethral stricture • Anterior urethral valve • Meatal stenosis
Ureteral Orifice • Normal cone shape • Horseshoe shape • Stadium shape • Golf hole shape • Short submucosal ureteral tunnel
Female Urethral Incompetence • Bladder neck incompetence • Urethral incompetence
Uroradiology in Lower Urinary Tract Dysfunction • Intravenous pyelography (IVP) • Retrograde pyelography • Cystography • Voiding cystourethrography • Retrograde urethrography • Beaded chain cystourethrograph • Magnetic resonance image (MRI)
Voiding Cystourethrography • Bladder neck dysfunction • Prostatic obstruction • Urethral stricture • Anterior urethral valve • Vesicoureteral reflux • Bladder diverticulum
Transrectal sonography • Prostatic configuration • Urethral stricture • Bladder neck incompetence • Bladder base hypermobility • Intravesical pathology
Prostate Configuration • Prostatic urethra • Transition zone of prostate • Seminal vesicle • Ejaculatory duct • Peripheral zone of prostate • Bladder neck
Transrectal sonography of the Prostate, Seminal vesicle, Urethra
Transition Zone Index (TZI) • Transition zone vol/ total prostate vol • A TZI of <0.3 indicates low possibility of prostatic obstruction, a TZI of >0.5 indicates highly suspicious prostatic obstruction • TZI correlates poorly with total prostatic volume
