Acute urinary retention in women: a prospective study of 18 consecutive cases.

Over a 9 month period 18 women were admitted for acute urinary retention to six different Copenhagen hospitals, serving a population of approximately 700,000 people. Urodynamically 9 patients had underactive detrusor function, 2 had infravesical obstruction and 3 had both underactive detrusor function and infravesical obstruction. In 4 patients bladder and urethral function were not classified. In 10 patients a provocative event preceded the retention episode. Eleven patients developed recurrent retention within 3 months and 7 patients had persistent severe obstructive voiding problems. Best prognosis was found for patients with correctable infravesical obstruction and for patients with minimal symptoms prior to the retention episode.
