title: Prediction of postoperative retention in elderly patients undergoing nonprostatic surgery by preoperative uroflowmetry.
abstract: 500 patients above 50 years of age, undergoing lower abdominal/perineal surgery and having no urinary complaints were assessed by measuring the preoperative maximum flow rate (Qmax). They were subsequently observed for urinary retention in the postoperative period. The analysis of the results has shown a definite relation between the preoperative Qmax and the probability of urinary retention in the postoperative period and uroflowmetry has been found to be a good screening procedure for the detection of cases which could possibly have urinary trouble requiring significant intervention in the postoperative phase, thereby changing the priority of surgical attention.
