OBJECTIVE: To assess the topography of the bladder neck by introital ultrasound before and after open colposuspension. METHODS: Three hundred and ten women with urodynamically proven stress urinary incontinence were included in this long-term study to investigate the position and function of the bladder neck at rest and during straining. Height (H), distance (D), and urethrovesical angle of the bladder neck (beta) were measured by means of preoperative and postoperative introital ultrasound. Women were followed up; 152 of them (49%) completed 48 months of follow-up. RESULTS: At the 6-month follow-up examination, 90.0% of the women were continent (279/310), 3.5% (11/310) showed voiding difficulties, 3.5% (11/310) had urgency, and 1.6% (5/310) had developed de novo urge incontinence. At the 48-month follow-up, 76.8% of the patients were still continent. All postoperative measurements yielded significantly lower values for angle beta at rest and during straining compared with the preoperative results (P < 0.0001). The median linear movement of the bladder neck during straining decreased from 18.0 mm before surgery to 6.4 mm at the 48-month follow-up (P < 0.0001). The median level of ventrocranial elevation of the vesicourethral junction was 14.3 mm immediately after surgery, 9.9 mm after 6 months and 6.6 mm after 48 months. The degree of surgical bladder-neck elevation was associated with postoperative urgency/de novo urge incontinence (P < 0.0001) and voiding difficulty (P < 0.0001). CONCLUSIONS: The colposuspension procedure reduces angle beta at rest and during straining, restricts linear movement with straining, and elevates the bladder neck. Perioperative introital ultrasound improves understanding of this surgical procedure and might help to prevent postoperative complications. Copyright 2004 ISUOG. Published by John Wiley & Sons, Ltd.
