Hypothesis / aims of study
Detrusor underactivity (DU) occurs in 9-48% of the population depending on age, sex and definition. We assessed the incidence and possible causes of DU in men and women having a urodynamic assessment at our institution for refractory lower urinary tract symptoms in a 20-month period.
Study design, materials and methods
We reviewed the urodynamic diagnosis and possible aetiology of all 1256 (510 male) patients attending for videourodynamics and simple urodynamics for the above indications between 31/5/16 and 3/1/18. Detrusor underactivity was defined as per 2002 ICS definition. Details on DU patient demographics and past medical and surgical history were determined and are detailed in Table 1. Statistical analysis was by T-Test and Chi Square analysis and significance determine as P < 0.05.
Interpretation of results
Neuropathic DU was significantly more common in women. Non-neuropathic women with DU were significantly younger than their male equivalents. Risk factors for non-neuropathic DU include previous SUI, POP or pelvic surgery in women and prior radical prostatectomy in men.
