|Aims and Objectives|
For elder male patients with acute urinary retention, it is difficulty to make sure how long the catheterization should be kept. Pressure-flow examination is always used to evaluate the extent of bladder outlet obstruction and bladder dysfunction, but the time to do such a study is conflicting. In our study, we try to solve those problems by analysing retrospectively the results of urodynamic examination on elder male patients with acute urinary retention.
