Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The PROCEPT Aquablation(TM) System (PAS) is intended to remove prostate tissue as a treatment for Benign Prostatic Hyperplasia (BPH).
The transurethral procedure involves the delivery of a high pressure water jet that cuts through tissue without thermal injury.
A dedicated surgical laser (the AquabeamTM), delivered through a column of water coagulates bleeding tissues.
The approximate duration of this procedure is 60 minutes.

Outcomes
Primary outcome [1] 288728 0
To evaluate the performance of the PAS device for the treatment of BPH. This outcome is assessed with a 5 point Likert Scale.
Timepoint [1] 288728 0
Completion of the intended surgical procedure.
Primary outcome [2] 288785 0
Incidence and Severity of Adverse Events. Anticipated adverse events might include prolonged catheterisation and haematuria. Based on ICH GCP Guidelines, AES are graded based on severity (mild, moderate, severe), relatedness to the device (definitely, likely, unlikely, definitely not) , relatedness to the procedure (as for device), and outcome (recovered, recovering, recovered with sequelae, ongoing). All Adverse events are documented, assessed by the investigator for severity, duration and frequency and reviewed by an Independent Assessor.
Timepoint [2] 288785 0
Procedure up until 3 years. A protocol amendment will now require follow up for 36 months with assessments at treatment, post procedure, 1 week, 1 month, 3 month 6 month and annual visits at 12, 24 and 36 months.
Secondary outcome [1] 300852 0
Change from baseline in IPSS (International Prostate Symptom Score) and IIEF (International Index of Erectile Function)
Timepoint [1] 300852 0
Post procedure, one week, One, Three, Six, twelve, twenty four and forty eight months.
Secondary outcome [2] 300853 0
Change from baseline in peak urinary flow rate, post-void residual volume and PDet/Qmax (Schaffer grade). These outcome measures are assessed using Uroflowmetry, Urodynamics and Ultrasound procedures.
Timepoint [2] 300853 0
Post procedure, one week, One, Three, Six, twelve, twenty four and forty eight months.
Secondary outcome [3] 300854 0
Change in prostate volume as determined via trans rectal ultrasound.
Timepoint [3] 300854 0
6 months
