Thulium laser resection of prostate-tangerine technique in treatment of benign prostate hyperplasia

Abstract

To evaluate the safety and efficacy of thulium laser resection of prostate-tangerine technique (TmLRP) in treatment of benign prostate hyperplasia (BPH). Thirty BPH patients, aged 74 (61-83), with a mean prostate volume of 58 ml, average international prostate symptom score (IPSS) of 19, and average maximum urinary flow (Q(max)) of 8.0 ml/s underwent TmLRP using 50 watt, 2.01 microm Tm laser. The values of hematocrit, serum sodium, potassium, and chlorine concentrations, hemoglobin, Q(max), and IPSS before and 1 and 3 months after TmLRP were compared. The mean operating time was 56 minutes. No significant bleeding was found during operation. Post-operative bladder irrigation was no necessary. The urethral catheter was indwelled for 1-3 days post-operatively. There were not significant differences in values of hematocrit, serum sodium, potassium, and chlorine concentrations, and hemoglobin before and 1-3 months after the operation. One month after the operation, the Q(max) was 23.1 ml/s and IPSS was 7.9, and 3 months after the operation the was 24.7 ml/s and the IPSS was 7.1. By the end of 3-month follow-up no new cases of impotence and retrograde ejaculation had been found. TmLRP is a safe and efficient procedure in treatment of BPH.
