PUL vs TURP in BPH Patients With Urinary Retention

Prostatic Urethral Lift Versus Transurethral Resection of Prostate in Benign Prostatic Hyperplasia Patients With Urinary Retention

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.

Inclusion Criteria:

• Male patients
• age >40 years old
• urinary retention who failed trial without catheter

Exclusion Criteria:

• Inability to provide consent OR no guardians or relatives to help provide consent on patient's behalf
• Active urinary tract infection
• Previous surgical treatment for benign prostatic hyperplasia (i.e., TURP, prostatic urethral lift, etc.)
• Bladder stones
• Urethral strictures or bladder neck contractures
• Prostate size >100mL
• Solely obstructing median lobe
• Urinary retention not due to obstruction (i.e., Bladder outflow obstruction index <20 on urodynamic studies)
