Design outcomes

Primary

MeasureTime frame
From invasive pressure flow study (if applicable): • Urethral resistance parameters (BOOI (Bladder Outlet Obstruction Index)) • Bladder contractility parameters (Wmax (maximum bladder contractility)) From non-invasive condom catheter measurements: • Isovolumetric bladder pressure (Pcond.max) • URR (urethral resistance); an experimental non-invasive measure for bladder outlet obstruction, calculated from the maximum condom pressure (Pcond.max) and the maximum free flow rate. [9]

Secondary

MeasureTime frame
From free flow-rate measurement: • Maximum urinary flow-rate • Voided volume From invasive pressure flow study (if applicable): • Detrusor pressure at maximum flow-rate • Maximum flow-rate • Urethral resistance parameters (URA (Urethral Resistance Factor), Average and slope of lowest part of PURR (Passive Urethral Resistance Relation)) • Bladder contractility parameters (BCI (Bladder Contractility Index)) From non-invasive condom catheter measurements: • Maximum flow-rate • Residual urine volume measured by transabdominal ultrasound • IPSS (International Prostate Symptom Score) questionnaire • QoL questionnaire
