[Comparison of the diode laser and the thulium laser in transurethral enucleation of the prostate for treatment of benign prostatic hyperplasia].
OBJECTIVE
To compare the validity and safety of diode laser and thulium laser transurethral enucleation of the prostate in benign prostatic hyperplasia (BPH) patients.


METHODS
In our study, 63 BPH patients treated with transurethral enucleation of the prostate were divided randomly into 2 groups by diode laser (Di group) or thulium laser (Thu group) respectively. The operation time, bleeding volume, electrolyte, international prostatic symptomatic score (IPSS), post-voiding residual volume (PVR) and maximum urine flow rate (Qmax) were recorded and compared.


RESULTS
No difference was found in the 2 groups in basic preoperative characteristics. Di group was superior to Thu group in mean operation time [(61.5±19.6) min vs. (71.4±16.5) min, P=0.026] notwithstanding little clinical sense. The mean time of removing catheter was 2.1 d and 2.3 d respectively. No difference in either electrolyte decrease or hemoglobin decrease [(5.0±1.1 g/L) vs. (4.4±0.9) g/L, P=0.32] peri-operation between the 2 groups were found and no transurethral resection (TUR) syndrome was encountered. Lower urinary tract symptom (LUTS) in both the groups were released the 1st and 3nd months post-operation effectively in IPSS, PVR and Qmax respectively and comparable (P>0.05).


CONCLUSIONS
Both the Diode laser and the Thulium laser transurethral enucleation of the prostate released the LUTS effectively in BPH patients and comparable in the short-time follow-up. Further study about late complications related to enucleation is necessary.
