The study will be a prospective, randomized controlled trial comparing prostatic urethral lift (PUL) versus transurethral resection of prostate (TURP) in benign prostate hyperplasia (BPH) patients with urinary retention. The primary objective of this study is to compare the catheter-free rates of PUL vs TURP. Secondary objectives include comparison of complications rates, cost effectiveness, patient satisfactory, symptom scores, quality of life measures and urodynamic parameters.
The study will be a prospective, non-inferiority randomized controlled trial with the aim of detecting a non-inferiority margin of 5%.
After the potential subject has been informed of the study and the potential risks, he will be screened for eligibility within a 4 week period. Assessment of eligibility will include questionnaires, blood tests, urine tests, uroflowmetry, flexible cystoscopy, transrectal ultrasound, and urodynamic study. Suitable subjects will then be randomized in a 1:1 ratio to the prostatic urethral lift (intervention group) and TURP (control group). Patients in the prostatic urethral lift will have the procedure performed under local anesthesia or monitored anesthetic care while TURP patients will be performed under spinal or general anesthesia. The subjects will have regular follow up 1 month, 3 months, 6 months, 1 year, 2 years, 3 years, 4 years, and 5 years post-operatively. Follow up assessments will include questionnaires, uroflowmetry, and occasional urodynamic study.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Prostatic Urethral Lift | Experimental | Prostatic urethral lift implants will be placed in patients under local anesthesia or monitored anesthetic care. The number of implants used will depend on intra-operative findings, ranging from 2 to 8 implants per patient. |
|
| TURP | Active Comparator | Transurethral resection of prostate (TURP) will be performed under spinal or general anesthesia as per usual care. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Prostatic Urethral Lift | Device | Prostatic urethral lift uses permanent implants to retract the prostate lobes away from the prostate urethra to allow unobstructed passage of urine. These implants are made of Nitinol, non-absorbable monofilament suture material (Poly Ethylene Terephthalate), Stainless Steel |
| Measure | Description | Time Frame |
|---|---|---|
| Catheter-free rates after prostatic urethral lift versus TURP in BPH patients with urinary retention | To determine how many patients will be catheter-free (defined as by the ability to void with a post-void residual urine <300mL) after intervention and remain catheter-free at 1 month, 3 months, and 1 year after intervention | 1 year after intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Compare complication rate of prostatic urethral lift versus TURP in BPH patients with urinary retention | To determine the percentage and severity of complications after each intervention (according to the Clavien-Dindo classification) | 5 years |
| Cost effectiveness of prostatic urethral lift versus TURP in achieving catheter-free rates in BPH patients with urinary retention |
