This present study was undertaken to evaluate the characteristic anatomic configuration of blader and urethra in patients with stress urinary incontinence before and after anterior-colporrhaphy d the efficacy of this operation as a corrective surgery for anatomic changes_
;´For these purposes, metallic beaded chain urethrocystography was conducted in 42 patients with ress urinary incontinence before and after anterior colporrhaphy and 10 normal continent control t Department of Obstetrics and Gynecology, Chung-Ang University Hopsital from March 1986 o September 1989.
The results were as follows:
Posterior urethrovesical angle and urethral inclination angle on straining were greater and posterior urethrovesical junction was lower in stress urinary incontinence than in normal continence.
2. Stress urinary incotment patients with abnormal urethal axis (Type II) showed significantly greater
, ~~
~
posteior urethrovesical and urethral inclination angles and lower posterior urethrovesical junc-4 Lion than in patients with normal urethral axis (Type I).
After anterior colporrhaphy, posterior urethrovesical and urethral inclination angles were significantly smaller and posterior urethrovesical junction was significantly elevated than before operation.
f But loss of posterior urethrovesical angle was not corrected in 38.1 To of all patient with stress ,urinary incontinence and posterior urethrovesical junction was still placed below the S-SS line in `57.1 07. Most of the type Il patients, especially, showed these findings.
From these results, we concluded that stress urinary incontinence is the results of anatomically defective supports of urethrovesical junction and urethra and stress urinary incontinence with abnormal urethral axis suggests more severe defective anatomic supports.
Anterior colporraphy is not considered as a proper surgical method for stress urinary incontinence
based on anatomical views because this procedure doesn´t satisfactorily correct abno urethroves;cal anatomic configurations.
