[Long-term clinical study of thulium laser resection of prostate-tangerine technique in the treatment of begin prostatic hyperplasia].

Objective To evaluate the long-term efficacies and complications of thulium laser resection of prostate-tangerine technique (Tm LRP-TT) in the treatment of benign prostatic hyperplasia (BPH). Methods From November 2004 to December 2009, a total of 348 BPH patients undergoing Tm LRP-TT at our hospital were evaluated retrospectively for long-term efficacies and complications.The follow-up data included international prostate symptom score (IPSS), quality of life score (QOL), maximum urinary flow (Qmax) and postvoid urinary residual (PVR). Results After 4 years, IPSS decreased 70% (22.7±7.7 vs 6.8±5.1), QOL decreased 65% (4.3±0.7 vs 1.5±1.0), Qmax increased 212% (6.0±2.6 ml/s vs 18.7±4.6 ml/s) and PVR decreased 83% (104.7±34.3 ml vs 17.7±10.7 ml).Cumulative incidences of long-term complications was 6.0% (n=21), including a second Tm LRP-TT due to BPH recurrence (n=4, 1.2%), urethral stricture (n=8, 2.3%) and bladder neck contracture (n=9, 2.6%).Overall, 93% were satisfied with surgical outcomes. Conclusion Tm LRP-TT has excellent efficacies with a low rate of long-term complications.Most patients are satisfied with surgical outcomes.
