Keywords
Benign prostatic hyperplasia, BPH, Urinary retention, prostate, hypertrophy
Brief summary
Assess feasibility and safety of the Prostatic Urethra Lift (PUL) procedure in patients with acute urinary retention secondary to benign prostatic hyperplasia (BPH).
Detailed description
The study is a multi-centre, prospective evaluation of PUL and retrospective review of invasive surgery as potential comparator. The study is intended to be conducted at up to 5 different centres in the United Kingdom to enrol up to 50 subjects. Subject follow-up visits are at post-procedure, 6 weeks, 3 months, 6 months and 12 months.
Interventions
Minimally invasive procedure in patients with acute urinary retention secondary to BPH.

Outcome results
Successful Trial Without Catheter Peri-procedurally
Success is defined as a spontaneous voided volume of ≥100 mL associated with a post void residual volume by ultrasound \<300 mL 3 days (± 1 day) after the index procedure catheter placement without the need for re-catheterisation.
Time frame: 3 days (± 1 day) from index procedure
Population: Trial Without Catheter information for retrospective arm was recorded as available from medical record, information from the UroLift System was prospectively collected
| Arm | Measure | Value (COUNT_OF_PARTICIPANTS) |
|---|---|---|
| UroLift System Procedure | Successful Trial Without Catheter Peri-procedurally | 29 Participants |
| Retrospective Arm | Successful Trial Without Catheter Peri-procedurally | 0 Participants |
Number of Participants With Serious Adverse Events Related to Benign Prostatic Hyperplasia (BPH) Intervention
Number of patients who experienced adjudicated Serious Adverse Events related to Benign prostatic hyperplasia (BPH) Intervention Procedure or Device
Time frame: Through 3 months
Population: Retrospective arm events were recorded from medical record and was not prospectively collected by sites compared to events collected prospectively from the UroLift System
