The subjects included 36 men and 6 women; mean age, 72 years (62\u201383 years).

The mean values for the maximum flow rate and post\u2010void residual (PVR) volume were 11.7 ml\/sec and 42.1 ml, respectively. PVR &gt;100 ml was noted in six patients (three men, three women; range, 100\u2013228 ml). Although the majority of patients had normal bladder volume at the first sensation (mean 134 ml), bladder capacity was small (mean 200 ml) and detrusor overactivity was seen in 95% of patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>While incontinence can result secondarily from gait disturbance or dementia, detrusor overactivity mostly underlies urinary urgency\/frequency and incontinence in iNPH.
