Prostatic Artery Embolization vs. Green Light PVP

Sponsor:

Royal Victoria Hospital, Canada

Code:

NCT02006303

Conditions

Benign Prostate Hyperplasia

Urinary Retention

Eligibility Criteria

Sex: Male

Age: 40 - 70+

Healthy Volunteers: Not accepted

Interventions

Green light PVP

Prostatic artery embolization

Study Details

Brief summary:

The primary objective is to assess whether prostatic artery embolization has a similar efficacy and safety profile as GreenLight PVP in treating patients with urinary retention secondary to benign prostate hyperplasia (BPH). Subjects who consent will be randomized to either the Prostate embolization (PAE) arm or to the GreenLight PVP arm.

The primary endpoint of efficacy of the procedure is measured by the ability of the patient to void. The secondary endpoints recorded will include patients' satisfaction measured by International Prostate Symptom Score (IPSS), peak flow rate (Qmax) and post-void residual urine volume (PVR) and prostate specific antigen (PSA) will be measured at 3, 6, and 12 months post treatment. Also, reduction in prostate volume is considered by MRI preoperatively, 3 months and 12 months.

Interventions and Outcome Measures

Arms

active comparator: Green light PVP

The KTP:YAG laser is based on the principle of passing Nd:YAG laser light through a KTP crystal. This halves the wavelength of the emitted laser to 532 nm and doubles its frequency. The emitted light is a visible green light, which is strongly absorbed by red tissues and hemoglobin; this renders a blood rich organ such as the prostate gland to be an excellent target. Prostate tissue is vaporized leaving an appropriate cavity for voiding.

active comparator: Prostatic Artery Embolization

Prostatic artery embolization consists of gaining access into the patients arterial system via a common femoral artery puncture using a small needle and sheath. Once the access is established, a micro-catheter is navigated through the arterial system using X-ray guidance into the arteries feeding the prostate. There, small polyvynil alcohol plastic beads are injected to block the blood flow to the prostate. By doing so, the prostate undergoes an ischemic injury and there is reduction in gland size and relief of obstructive symtpoms.

Interventions

Green light PVP

The green light laser has a wavelength of 532 nm which is strongly absorbed by red tissues and hemoglobin; this renders a blood rich organ such as the prostate gland to be an excellent target. The procedure uses the technology of high-powered laser light combined with fiber optics to vaporize the overgrowth of prostate cells quickly and accurately. As the surgeon directs the laser at the prostate, the intense pulses of light emitted from the fiber are absorbed by the blood. Within moments, the temperature of the blood becomes so great it causes the nearby cells to vaporize. Once the procedure is completed, patients have immediate post-operative symptom relief and dramatic improvements in symptoms, urinary flow rates, and bladder emptying.

Primary outcome measure

  • Ability of the patient to void after removal of the urethral catheter [ Time Frame: At 24-hours for PVP green light laser and 1-3 weeks for embolization ]
