A comparative study on the photoselective vaporization of the prostate and transurethral electrovaporization resection of prostate for the treatment of benign prostatic hyperplasia / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To compare the therapeutic effects of the greenlight photoselective vaporization of prostate (PVP) and transurethral electrovaporization resection of prostate (TUVP) for the treatment of symptomatic benign prostatic hyperplasia (BPH).</p><p><b>METHODS</b>One hundred and sixty-three cases of BPH were treated with PVP and TUVP. All patients were followed up with International Prostatic Symptom Score (IPSS), quality of life (QOL), blood loss, operative time, indwelling catheterization, mean Qmax, residual urinary volume (RUV) and operative complications.</p><p><b>RESULTS</b>IPSS, QOL, Qmax and RUV were significantly improved after either of the procedures (P < 0.05), no significant difference in the improvement of subjective symptoms and objective signs had been noted with the different procedure (P > 0.05). Mean operative time was (37 +/- 15) min for TUVP and (45 +/- 28) min for PVP, the resection time was longer for PVP than TUVP (P > 0.05), but the intraoperative bleeding and catheterization time were less for PVP than TUVP (P < 0.05). Postoperative complications were less for PVP than TUVP (P < 0.05). The incidence of hematuria in TUVP group had been 41.4%, and urinary irritation after PVP group was 55.2% (P < 0.05).</p><p><b>CONCLUSIONS</b>PVP has the same therapeutic effect as TUVP and less adverse side effects than TUVP. It is a new technique for the treatment symptomatic BPH.</p>
