Residual urine: This may occur if the urine is not completely emptied after micturation. This is called residual urine--it never leaves. The most common reasons are obstruction--an enlarged prostate, urethral stricture, or low bladder voiding pressures due to neurological or other diseases. Diabetes, for example can lead to poor bladder emptying. There may also have been prior infections or surgery.
