Two-micron laser resection of the prostate-tangerine technique for the treatment of large-volume prostate / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical efficiency and safety of two-micron laser resection of the prostate-tangerine technique (TmLRP-TT) for the treatment of large-volume ( > 70 ml) prostate in patients with benign prostatic hyperplasia (BPH).</p><p><b>METHODS</b>This retrospective analysis included 80 BPH patients with the prostatic volume larger than 70 ml, all treated by TmLRP-TT. We comparatively analyzed the levels of hemoglobin and serum sodium before and after surgery, recorded intra- and post-operative com- plications, and followed up the patients at 6 and 12 months after operation for International Prostate Symptom Score (IPSS), quality of life (QOL), maximum flow rate (Qmax), and postvoid residual urine volume (PVR).</p><p><b>RESULTS</b>All the operations were successfully completed. The mean hemoglobin decreased (0.68 +/- 0.43) g/dl intraoperatively, but no apparent reduction was observed in serum sodium. Lower urinary tract symptoms were relieved significantly in all the cases. At 12 months after surgery, IPSS was decreased by 73.89% as compared with the baseline (20.03 +/- 6.9 vs 5.23 +/- 3.59), QOL by 64.55% (4.09 +/- 1.19 vs 1.45 +/- 1.36), and PVR by 79.30% (97.31 +/- 57.90 vs 20.14 +/- 24.20 ml), while Qmax increased by 140.42% ([8.04 +/- 3.62] vs [19.33 +/- 3.28] ml/s). The incidence of complications was low either intraoperatively or during the 12 months after operation.</p><p><b>CONCLUSION</b>TmLRP-TT is a safe and effective surgical endoscopic approach to the treatment of large-volume prostate in BPH patients.</p>
