Objective To compare the efficacy and safety of a novel thulium fiber laser for endoscopic enucleation of the prostate with monopolar transurethral resection of the prostate in patients with smaller glands (<80 cc). Methods A total of 51 patients underwent thulium fiber laser enucleation of the prostate, and 52 patients underwent monopolar transurethral resection of the prostate. All patients were assessed preoperatively, and at 3, 6, and 12 months postoperatively (International Prostate Symptom Score, maximum urine flow rate, International Prostate Symptom Score‐quality of life). Preoperative prostate volumes and prostate‐specific antigen levels were comparable ( P = 0.543 and P = 0.078, respectively). The complications were graded according to the Clavien classification. Results Mean surgery time was longer in the thulium fiber laser enucleation of the prostate group (46.6 ± 10.2 vs 39.9 ± 8.6 min, P < 0.001), while catheterization and hospital stay were greater in the transurethral resection of the prostate group ( P < 0.001). At 12 months, there were no differences in functional outcomes (International Prostate Symptom Score, maximum urine flow rate). Despite comparable prostate volumes at 12 months ( P = 0.864), the prostate‐specific antigen level in the thulium fiber laser enucleation of the prostate group (0.5 ± 0.5 ng/mL) was lower than in the transurethral resection of the prostate group (1.1 ± 1.0 ng/mL; P < 0.001). Hemoglobin and serum sodium decrease was lower in the thulium fiber laser enucleation of the prostate group (1.01 ± 0.4 g/ dL and 1.1 ± 1.1 mmol/L) than in the transurethral resection of the prostate group (1.8 ± 0.8 g/ dL and 4.1 ± 1.1 mmol/L; P < 0.001). Urinary incontinence rates at 12 months were comparable ( P = 0.316). Conclusions Thulium fiber laser enucleation of the prostate with novel thulium fiber laser in patients with smaller prostate glands (<80 cc) is comparable to transurethral resection of the prostate in voiding parameters improvement and complication rates. At the same time, the technique allows for a more substantial prostate‐specific antigen decrease, indicating more complete removal of adenoma.
