Objective: In recent years, laser treatments have re-emerged as options for treating benign prostatic hyperplasia (BPH). This paper reviews the safety, efficacy, effectiveness and economics of photoselective vapourization of the prostate (PVP), compared with transurethral resection of the prostate (TURP). Methods:We conducted a comprehensive literature search to identify 14 studies comparing 80 W PVP and TURP. We then reviewed and pooled these studies. Results:We identified 12 adverse events or complications; rates were similar in both groups. No PVP patient required a blood transfusion; 5%-11% of TURP patients did. PVP patients had a significantly lower likelihood of clot retention. Collectively, the 14 studies led to the conclusion that PVP is a safe procedure. PVP is favourable to TURP regarding length of hospitalization and catheterization times. There were no meaningful differences in operation times, reoperation rates, peak flow rates, postresidual volumes or quality of life scores. Sexual function and prostate specific antigen value changes were similar. Four economic evaluations of PVP and TURP (from Canada, Switzerland, Australia and the United States) concluded that PVP is less costly per case than TURP. Cost differences are attributable to disposables, capital equipment and hospitalization. Based on our analysis of limited Canadian data, the cost of PVP is estimated to be about one-half that of TURP, even after accounting for start-up costs. Conclusion:The 80 W PVP laser appears to be a viable treatment for BPH.With the recent regulatory approval of the 120 W High Performance System (HPS), an additional option has become available. Therefore, it is anticipated that PVP will soon be considered part of a physician's repertoire for managing BPH.

“…Many studies have already shown that, on a short‐term basis, photoselective vaporization of the prostate (PVP) using the KTP 80 laser is safe and effective and, at the same time, maintains minimal invasiveness [2–6]. The foremost advantages of KTP laser prostate endovaporization is to enable PVP in anticoagulated patients with high anaesthesiological risk in the presence of a moderately enlarged prostate [4,5,7–9] and to allow 1‐day surgery with a limited cost [4,5,10–13]. However, the length of the procedure, as well as medium‐term complications, such as bladder neck and urethral stricture or reintervention rates, are not negligeable in KTP laser‐operated patients.…”

symptomatic benign prostatic hyperplasia over a period of 17 months. PVP was performed by two senior urologists.• The power of laser beam at tip exit was measured for each fibre at the end of the procedures using a photodiode whose signal was amplified, and then quantified by a volt multimeter.• The deflection angle was measured using a graduated sphere. RESULTS• Approximately 70% of fibres delivered less than 40 W at the end of the procedure, which is less than the vaporization threshold.• Some 9% of fibres had lost their diffraction capacity with a significant alteration of laser beam angulation. These values were not operator dependent. CONCLUSIONS• The data show that a large proportion of laser fibers deliver a significantly underpowered beam at the end of the procedures.• This seems to be caused by peroperative destruction of the fibers, which results in a progressive loss of efficacy of PVP during procedures.
