Urinary retention. Can be caused by blockage as in an enlarged prostate or stool impaction (severe constipation) or bladder stone causing obstruction, neurogenic bladder dysfunction where there is temporary or permanent nerve damage and the urinary sphincter can not relax and allow bladder to empty, or infection causing swelling of bladder neck and hence blockage. Needs care by a urologist.
