    Abstract:
    OBJECTIVE: To evaluate the position of the bladder neck before and after open Burch colposuspension, using introital ultrasound. DESIGN: Retrospective longitudinal study using pre- and post-operative sonographic assessment of the position and function of the bladder neck. SETTING: Urogynecology units at the universities of Marburg/Göttingen and Witten/Herdecke and the DRK district hospital in Alzey, Germany. PATIENTS: 310 women undergoing open Burch colposuspension for primary genuine stress incontinence between September 1992 and December 2001. METHOD: Two-dimensional introitus sonography of the bladder neck prior to, one week and six months after surgery. RESULTS: The median age at surgery was 55 years (26 - 85). Open colposuspension lead to a 90.0 % (279/310) cure rate at 6 months with only 3.5 % (11/310) of the patients showing persistent micturation problems. A further 11.6 % (36/310) had symptoms of urgency and in 7 patients (2.3 %) a de novo urge-incontinence occurred. Post-operative bladder neck angles and movements at rest and during valsalva manoeuvre were significantly reduced while the resting bladder neck position was significantly elevated (p < 0.0001). Anatomical elevation of the bladder neck after open colposuspension varied between 2 - 39 with a median of 14.3 mm of neck elevation after one week and 9.9 mm at 6 month, respectively. Incontinence surgery lead to a significant reduction of the urethral funneling (p < 0.0001). CONCLUSION: In our series, open Burch colposuspension decreased both the bladder neck angle and the linear movement at rest and on valsalva as a result of the surgically stabilized bladder neck. Thus, our results support the hammock hypothesis that even small changes in the position of neck position are sufficient to reverse incontinence. We believe that perioperative introitus sonography is a helpful tool for the clinical assessment and documentation of not only morphological but also functional changes of the female continence organ before and after open Burch colposuspension.
