Study design, materials and methods
We reviewed retrospectively the urodynamic diagnosis and presenting symptoms of all 1256 (510 male) patients attending for videourodynamics (VUDS) and simple urodynamics (UDS) between 31/5/16 and 3/1/18. Detrusor underactivity was defined as per 2002 ICS definition as "a contraction of reduced strength and/or duration, resulting in prolonged bladder emptying and/or a failure to achieve complete bladder emptying within a normal time span". Details on DU patient demographics and symptoms were determined and are detailed in Table 1. Statistical analysis was by T Test and Chi Square analysis and significance determined as P < 0.05.
Interpretation of results
From our results it can be noticed that the female group was significantly younger with a median age of 53, against a median age of 65 for the male group. The most frequent presenting symptoms for the female cohort were, in a descending order, urgency, UUI, SUI, nocturia and incomplete emptying. On the other hand, for the male cohort the main presenting symptoms were nocturia, frequency, urgency, poor flow. The main differences between the two groups regarded UTI and UUI that were 19% and 12% more frequent in the female group compared to the male one respectively. The male group had a 10% higher presentation of inability to void when compared to the other sex.
