To report the results of a randomized prospective trial with a 4-year follow-up, comparing the thulium laser resection of the prostate-tangerine technique (TmLRP-TT) with transurethral resection of prostate (TURP) for treatment of symptomatic benign prostatic hyperplasia (BPH).


BPH patients (96) were randomized for surgical treatment with TmLRP-TT (47) or TURP (49). All patients were assessed pre-operatively and followed at 12, 24, 36, and 48 months post-operatively. Several parameters related to BPH were collected at each follow-up, including International Prostate Symptom Score (IPSS), quality of life (QoL), maximum urinary flow rates (Qmax), and post-void residual volume (PVR). All late complications were also recorded.


Dramatic improvement in micturition parameters was observed after TmLRP-TT compared with pre-operative values. Median IPSS decreased 75.6 % in the subsequent 12 months and 61.2 % in 48 months, while median QoL decreased by 80.4 and 59.1 %, respectively. Compared with baseline, numerical values of Qmax increased 1.07-fold and those of PVR decreased 73.1 % in the fourth year. Moreover, all micturition parameters in the TmLRP-TT group were similar to those of TURP patients at every annual assessment. Some late complications after the operations were also observed: one patient suffered from urethral strictures and one from bladder-neck contractures after TmLRP-TT. Re-operation rates were equal in the two groups.


Micturition remained stable after TmLRP-TT during the 4-year follow-up. Outcomes compared favourably with TURP, with lower peri-operative morbidity and equally low occurrence of late adverse effects. Thus, TmLRP-TT can be an available option for BPH patients, especially older, high-risk patients.
