ABSTRACT
Objective To discuss the safety and efficacy of straight light beam greenlight photoselective vaporesection of the prostate (PVRP) and photoselective vaporization of the prostate (PVP) in treatment of benign prostatic hyperplasia. Methods 113 cases of BPH were randomly divided into two groups, 62 cases in PVRP group and 51cases in PVP group. Clinical data was collected and compared between the two groups, including pre-operation and six month after operation international prostate symptom score (IPSS), quality of life (QOL), urine flow rate (Qmax), postvoid residual urine (PVR), as well as operational time, operative bleeding volume, bladder irrigation time, indwelling catheter time after operation and complications after operation. Results All the patients were operated successfully without serious complications. There was significant difference in operative time [(49.4 ± 18.9) min vs (75.1 ± 20.7) min (P 0.05). Conclusions Treatment of straight light beam greenlight PVRP and PVP are safe and effective for BPH. Straight light beam greenlight PVRP has the advantages of shorter operation time.
ABSTRACT
Objective To study the safety and clinical efficacy of transurethral 120 W 2 μm laser prostate vaporesection in the treatment of benign prostatic hyperplasia (BPH).Methods Forty-one BPH cases were treated with 2 μm continuous wave laser prostate vaporesection.Laser output power was 120 w.International prostate symptom scores (IPSS) were collected on all patients before and after surgery at one,six and 12 months for maximum urinary flow rate (Qmax) and post-voiding residual urine volume (PVR).Operative time,estimated bleeding loss,electrolyte changes,and the time of catheter removal were recorded and analyzed respectively.Results All procedures were successfully completed.The obstructive symptoms of lower urinary tract symptoms were relieved in varying degrees post-operatively.Preoperative and postoperative one,six and 12 months IPSS,Qmax and PVR showed statistical difference ( P ＜0.01 ).Operative time was 32.9 ± 10.7 min,decreased hemoglobin levels was 5.36 ± 2.78 g/L,no cases needed blood transfusion,and all patients were without electrolyte disturbance resulted in the safe perioperative period.The time of removal of the catheter was 2.5 ± 0.7 d.There was no secondary surgery,urinary incontinence,and complication such as bladder neck contracture at 12 months post-operative follow-up.Conclusions RevoLix 2 μm continuous wave laser prostate vaporesection as a treatment option for BPH is safe and effective over a short and long period of time.RevoLix 2 μm wave laser prostate vaporesection can significantly improve BPH patient symptoms of lower urinary tract obstruction.
