(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
It seems that cure rates are lower for patients who are unable to contract their external sphincter, have a poor response to midperineal pressure test during dynamic urethroscopy
and those with scarred and immobile urethra, i.e.
If the urethroscopy
findings were different than our initial RGU, we changed our initial operative plan.
, urethral stricture was found in nine rabbits 2 weeks after the operation.
(3) MRI is a useful modality for the evaluation of pelvic pathology and has been reported to have a higher sensitivity for the depiction of urethral diverticula than VCUG or urethroscopy
. (3) It allows for detailed evaluation of anatomic relationships between the diverticulum and adjacent structures.
Other Methods Used to Treat Calculi: Medication, Urethroscopy
and Percutaneous Nephrolithotomy
Some authors (6) suggest urethroscopy
if lesions are seen in the distal urethra, although in practice rarely is urethroscopy
done unless recurrent lesions are apparent (personal communication with Alex Ferenczy, MD, Professor of Pathology, Obstetrics & Gynecology, Sir Mortimer B.
In his urethroscopy
, anterior urethral stricture 2 cm in length was determined.
was attempted under general anesthesia that failed due to complete obstruction at 1 cm from the meatus.
Stenosis was conferred as the area of narrowing visible in the urethra or gripping felt during urethroscopy
. A higher value of Qmax from non-intubated uroflowmetry and lower value of PVR were taken for the analysis from 2 consecutive readings.
Prior to sacrifice, animals underwent retrograde urethrograms (RUG) and urethroscopy
. Histologic specimens were examined for presence of buccal mucosal engraftment.
