In a nutshell
This study investigated the effects of WAVE (Water Vapor Energy Ablation) – a new procedure to relieve urinary symptoms due to benign prostate hyperplasia (BPH). WAVE was found to be a simple, effective and safe method of treating BPH symptoms.
Some background
Benign prostatic hyperplasia may lead to troublesome urinary symptoms, often requiring surgical intervention. Since surgical interventions are associated with significant side effects, particularly concerning sexual function, less invasive techniques have been developed over the years. Prostatic water vapor energy ablation (WAVE) is a new, minimally invasive procedure to treat BPH symptoms. Water vaper leads to the death of some prostate cells, decreasing blockages and improving the flow of urine.
Methods & findings
The trial included 197 men with BPH and urinary symptoms. 136 patients were randomized to WAVE treatment. 61 patients received a sham procedure and acted as the control (comparison) group. Patients were followed for 12 months, and were asked to report on urinary symptoms, quality of life, and any unwanted side effects.
Men receiving WAVE reported greater improvements in BPH related symptoms compared to patients in the control group. Improvements in symptoms were noted from two weeks following the procedure, and were sustained throughout the follow-up period.
Unwanted side effects, such as local pain or irritation, were mild to moderate and resolved quickly. No cases of erectile or sexual dysfunction were reported among men undergoing WAVE.
The bottom line
The researchers concluded that WAVE is an effective and safe method of treating BPH symptoms.
The fine print
Larger randomized trials, including longer follow-up periods, are required to confirm these preliminary results. Long term effects of WAVE should be compared to those of other known procedures for BPH.
