The RevoLix 120 W 2 microm continuous-wave laser vaporesection of the prostate for the treatment of high-risk patients with benign prostatic hyperplasia

Abstract

Objective To evaluate the safety and efficacy of the RevoLix 120 W 2 microm continuous-wave laser vaporesection of the prostate for the treatment of high-risk patients with benign prostatic hyperplasia(BPH).Methods From January to December 2010,62 high-risk patients with BPH underwent 2 microm continuous-wave laser vaporesection of the prostate.The operative time,decreased index in hemoglobin,decreased index in serum sodium,indwelling catheterization time,operative complications,international prostatic symptom scores ( IPSS ),quality of life( QOL ) scores,peak urinary flow rate (Qmax),and post voiding residual urine volume (PVR) were observed.Results All 62 patients recovered without incidents.Transfusions were not necessary in any patients.The operative time was (52.6 ± 28.2) min.The diseases of heart,brain,liver,kidnty were not worsen after operation.The indwelling catheterization time was 3-6 days.Hemoglobin decreased from preoperative ( 132 ± 26) g/L to postoperative ( 128 ± 21 ) g/L,serum sodium decreased from preoperative (142.4 ± 4.9) mmol/L to postoperative (141.2 ± 3.8) mmol/L.There were not significantly different between preoperative and postoperative results (P ＞ 0.05).All cases were followed up for (7.2 ±3.5) months,Qmax increased from (7.6 ±4.2) ml/s to (21.8 ±5.9) ml/s,PVR decreased from ( 124.4 ± 206.2) ml to (21.5 ± 26.5 ) ml.IPSS and QOL scores decreased from preoperative (20.4 ±6.8) and (4.5 ±0.9) scores to postoperative (6.2 ±2.2) and (2.0 ±0.3) scores.There were significantly different between preoperative and postoperative results(P ＜ 0.01 ).Conclusions The RevoLix 120 W 2 microm continuous-wave laser vaporesection of the prostate is safe and effective for the treatment of high-risk patients with BPH.But should improve surgical techniques in the operative procedure and strengthen individual perioperative management.
