To evaluate the reliability of diagnosing type of bladder suspension defect in incontinent women by means of voiding colpo‐cysto‐urethrography (CCU), 93 CCU‐series with exposures at rest, coughing, withholding and voiding were diagnosed. Three senior and one junior radiologists, a gynecologist and a urologist diagnosed the CCU‐series twice with 3‐6 months interval. The main diagnostic possibilities were anterior bladder suspension defects, posterior defects and normal, which were in accordance with general practice of choosing an abdominal suspension operation for the anterior suspension defects and a vaginal operation for the posterior defects. The intra‐observer agreement varied between 99% and 72%, i.e. 1/5 to 1/ 4 of the patients changed from one main diagnostic group to another at the two examinations. The inter‐observer agreement varied between 43% and 60%. Information of clinical patient data, given to the two clinicians, did not change their CCU‐diagnoses significantly. We concluded, that CCU should not be recommended as a routine for evaluation of type of suspension defect since the intra‐inter‐observer variation was around 25% and 50% respectively. CCU might still be useful preoperatively in selected cases, since it gives an excellent visualisation of bladder base anatomy.
