Diode Laser Enucleation vs. Bipolar Transurethral Enucleation of Prostate for Benign Prostatic Hyperplasia: A Retrospective Comparative Study with Three-Year Follow Up.

Objective: To assess the clinical outcome of 1470 nm diode laser enucleation of the prostate (DiLEP) vs. bipolar transurethral enucleation of prostate (TUEP) for benign prostatic hyperplasia (BPH).

Methods: One hundred and fifty-seven patients were retrospectively involved in this study. Eighty-two patients underwent DiLEP while 75 underwent bipolar TUEP. Seventy-three patients in DiLEP and sixty-nine in bipolar TUEP completed the 3-year follow-up, respectively. The baseline properties, perioperative data, and postsurgical outcomes were evaluated.

Results: No statistically significant differences were found between DiLEP and bipolar TUEP in preoperative parameters. Significantly shorter operating time was noted in DiLEP group ( = 0.000). No patient suffered dangerous complications, and none in either group required a blood transfusion. No statistically significant differences were found between DiLEP and bipolar TUEP in the decrease in hemoglobin or sodium. During the 3-year postoperative follow-up, ongoing and significant improvements were found in both groups without any difference.

Conclusions: Both DiLEP and bipolar TUEP can improve low urinary tract symptoms (LUTS) secondary to BPH in a comparable way with high efficacy. Compared with bipolar TUEP, DiLEP with a morcellator required a shorter operative time.
