Abstract

This present study was undertaken to evaluate the chacteristic anatomic configuration of bladder and urethra in parients with cervical cancer before and after radical hysterectomy. From July 1994 to December 1996, metallic beaded chain urethrocystography was conducted in 33 patients with cervical cancer before and after radical hysterectomy at Holy Family hospital. The results were as follows 1. After radical hysterectomy, posterior urethrovesical angles at rest and strain were significantly increased (P = 0.0004 at rest, P = 0.0016 at strain) and posterior urethrovesical junction at rest and strai were significantly descended (P = 0.004 at rest, P = 0.0024 at strain). 2. Postoperative urethral inclination angle at rest was greater than before radical hysterectomy (P = 0.002), but postoperative urethral inclination angle at strain was not increased statistically (P > 0.05). From these results, we concluded that stress urinary incontinence after radical hysterectomy is the results of anatomically defective supports of urethrovesical junction and urethra. We must consider a proper surgical method to prevent stress urinary incontinnce and anatomical defect of urethrovesical junction.
