GreenLight Laser Photoselective Vaporization of the Prostate vs Bipolar Transurethral Vaporization of the Prostate; RCT

Patients with LUTS due to BPH seen through the outpatient prostate clinic in the Mansoura UNC were assessed to evaluate if the patient is eligible to the study inclusion criteria. Patients who are meeting these criteria were asked to participate in this randomized comparative study and were provided with an informed consent form. Study participants were enrolled and randomized, and the appropriate scheduled procedures were performed.

Preoperatively, all patients were thoroughly evaluated by medical history and physical exam, digital rectal exam (DRE), prostate specific antigen (PSA), urinalysis and urine culture, international index of prostate symptom score (IPSS), Quality of Life (QOL), transrectal ultrasound (TRUS) measurement of prostatic volume and biopsy whenever indicated, measurement of post-void residual assessment (PVR), and maximum urinary flow rate (Qmax). Preoperative flexible urethrocystoscopy was done when hematuria was the presenting symptom.

Inclusion criteria

• Patients' age ≥50 years
• LUTS secondary to BOO due to BPH who failed medical treatment
• International prostate symptom scores (IPSS) >15 and bother score (QOL) ≥ 3 (according to IPSS question 8)
• Peak urinary flow rate (Qmax) <15 ml/sec with at least 125 ml voided volume or Patients with acute urine retention secondary to BPH who failed trial of voiding on medical treatment.
• ASA (American society of anaesthesiologists) score ≤3.
• TRUS prostate size (from 30 to 80ml)

Exclusion criteria

• Patient with neurological disorder which might affect bladder function as cerebrovascular stroke, Parkinson disease
• Active urinary tract infection,
