Evaluation of greenlight photoselective vaporization of prostate for the treatment of high risk older patients with benign prostatic hyperplasia

【Objective】To evaluate the safety and efficacy of greenlight photoselective vaporization of prostate (PVP) in high risk older patients with benign prostatic hyperplasia (BPH). 【Methods】A total of 63 high risk older patients with BPH underwent PVP. The operativetime,bloodloss,indwelling catheterization and operative complications were observed. The variables such as IPSS,QOL,uroflowmetry,post-void residual urine volume (RUV) were recorded and calculated pre-operatively and post-operatively.【Results】All the 63 patients safely got through perioperative period. The preoperative concurrent diseases of heart,lung,brain,liver and kidney were not aggravated after PVP operation. The mean operative time was (44.8 ± 6.5) min,intraopera-tive blood loss was (85.4 ± 12.4) mL and postoperative indwelling catheterization was (3.5 ± 0.5)d. IPSS and QOL scores decreased form preoperative (30.8 ± 4.3) and (6.2 ± 0.6) to postoperative (9.5 ± 1.3) and (2.6 ± 0.4) respectively. Qmax increased from(6.3 ± 2.1) mL/s to (17.4 ± 3.6)mL/s,and RUV decreased from (154.0 ± 20.5) mL to (29.6 ± 6.8) mL. There were significant differences of these parameters between pre-operation and post-operation (P 0.05).【Conclusions】The PVP is believed to be a safe,efficacious and minimally invasive procedure for older patients with high risk BPH. It is easier to manipulate with advantages of shorter operative time,less blood loss,better tolerance and rapid recovery.
