CT examination has been shown to be effective in detecting bladder cancer. Proper evaluation of the bladder requires it to be well distended. The purpose of the present study was to establish a preparation protocol to achieve satisfactory bladder distension without causing unacceptable patient discomfort.
Material and method
We used four different preparation protocols (1: 0.5 L of fluid intake during a 1-h period, 2: Same as 1 with the addition of IV diuretics when the patient was examined, 3: 1 L of fluid intake during a 2-h period, 4: Same as 3 with the additional instruction to empty the bladder after 1 h. In protocols 1–3, the patients were asked not to empty their bladder during the preparation time). Bladder volume was calculated and bladder distension was judged as satisfactory or not by the radiologist. The patients answered questions about their ability to follow the preparation protocol and were requested to rate their need to empty the bladder pre-, during and post-examination.
Protocol 1 had the lowest bladder volume. Protocols 2, 3 and 4 were similar in bladder volume. However, Protocol 2 caused unacceptable patient discomfort, and the compliance was lowest in Protocol 4.
Protocol 3, drinking 1 L of fluid during a 2-h period, gave satisfactory bladder distension, did not cause unacceptable discomfort in patients and did not have the lowest compliance.
