(11) In the present study, urethral stricture was defined as a Qmax <10 mL/s on uroflowmetry and the visibility of the stricture site on urethroscopy or urethrography
. The rate of Qmax <10 mL/s was 6.06% in group A and 15.15% in group B by uroflowmetry.

However, in the case of accessory or hyposplastic urethras or non-communication a retrograde urethrography
may be required.
of distal urethra shows ballooning of contrast within foreskin caused by stenosis of its distal opening.
Results: Retrograde urethrography
showed 100% sensitivity, 97.78% positive predictive value and 97.78% diagnostic accuracy.
Double contrast cystography and/or retrograde urethrography
may identify radiolucent stones in bladder or urethra.
One week preoperatively and 2, 4 and 8 weeks postoperatively, all the animals underwent urethroscopy and urethrography
. At 2, 4 and 8 weeks postoperatively, two animals were randomly selected and killed, and the urethra was cut off for pathological examination.
A retrograde urethrography
was taken to visualise both urethral tracts.
After screening, uroflowmetry, retrograde urethrography
and cystometry were performed in selected patients.
Preoperative studies included retrograde urethrography
, voiding cystography, and urethroscopy.
The most commonly used methods to characterize the lesions preoperatively are antegrade cystourethrography and retrograde urethrography
. Pelvic computerized tomography and magnetic resonance imaging are also helpful in determining the depth of the lesion and bony structures.
