摘要

Introduction and objectives: It is unknown if tissue ablation following 120W lithium triborate (LBO) laserrnvaporization (LV) of the prostate is comparable to that following transurethral resection of the prostate (TURP).rnTherefore, transrectal 3D-ultrasound volumetry of the prostate was performed to compare the efficiency of tissuernablation between LBO-LV and TURP.rnMethods: Between 03/2008 and 03/2010 110 patients underwent routine LBO-LV (n=61) or TURP (n=49). Transrectalrn3D-ultrasound with planimetric volumetry of the prostate was performed pre-operatively, after catheter removal, 6 weeksrnand 6 months.rnResults: Median prostate volume was 52.5ml in the LV group and 46.9ml in the TURP group. After catheter removal,rnmedian absolute volume reduction (LV: 7.05ml, TURP: 15.8ml) and relative volume reduction (15.9% vs. 34.2%) werernsignificantly lower in the LV group (p<0.001). After 6 weeks/ 6 months, the relative volume reduction but not thernabsolute remained significantly lower in the LV group.rnConclusions: LBO-LV is an efficient procedure evidenced by an absolute tissue ablation not significantly different tornthat after TURP. However, TURP seems to be superior due to a higher relative tissue ablation. The differences in tissuernablation had no impact on the early clinical outcome. Delayed volume reduction indicates that prostatic swelling occursrnearly after LV and then decreases subsequently.
