Comparison of transurethral electrovaporization-ablation prostatectomy and greenlight photoselective vaporization prostatectomy for symptomatic benign prostatic hyperplasia

Objective To evaluate and compare the therapeutic effects of transurethral electrovaporization-ablation prostatectomy (TUEVAP) and greenlight photoselective vaporization prostatectomy (PVP) for the treatment on benign prostatic hyperplasia (BPH). Methods 186 symptomatic BPH patients randomly underwent TUEVAP (n = 92) or PVP (n = 94) and the therapeutic effects were evaluated. The operative time,blood loss,indwelling catheterization,subjective symptoms and operative complications were observed. Results IPSS score,QOL,Qmax and PVR in all the patients were significantly improved after either of the procedures (P 0.01). No significant difference in the improvement of subjective symptoms and objective signs was noted for the different procedures (P 0.05). The mean operative time and indwelling catheter time were longer in the TUEVAP group (P 0.01). The intraoperative blood loss and the occurrence of postoperative retreatment,urethral stricture and delayed hemorrhage were more in the TUEVAP group too (P 0.05). Conclusions The therapeutic effect of TUEVAP is similar to PVP′s,but PVP is easier to manipulate with advantages of shorter operative time,less blood loss,more rapid recovery and fewer complications.
