The aim of this study was to evaluate efficacy and safety of 1470 nm diode laser enucleation of the prostate (DiLEP) and plasmakinetic resection of the prostate (PKRP) in elderly benign prostatic hyperplasia (BPH) patients with lower urinary tract symptoms (LUTS).
A total of 123 elderly patients with BPH were randomized to undergo either 1470 nm DiLEP or PKRP by means of a random number table from September 2020 to April 2022. The perioperative and postoperative data were studied during a 3,6-month follow-up.
the patients treated with 1470 nm DiLEP had significantly decreased operation time (74.6±17.0 vs. 98.8±18.9 min, p < 0.001), hemoglobin loss (1.06±0.49 vs. 1.59±0.60 g/dl, p < 0.001), bladder irrigation time (22.1±8.1 vs. 33.9±10.0 h, p < 0.001), catheter duration (3.2±1.3 vs. 5.8±1.0 d, p < 0.001), and hospital stay (7.6±1.4 vs. 9.6±1.3 d, p < 0.001) compared with the PKRP group. Besides, International Index of Erectile Function (IIEF)-5 score of 1470 nm DiLEP group at postoperative 3,6-month follow-up was significantly higher than PKRP group. No differences achieving statistical significance were identified in total Prostate Specific Antigen (tPSA), maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), quality-of-life score (QoL), and the postvoid residual urine volume (PVR), transient incontinence, urethral stricture, bladder neck contracture and retrograde ejaculation at 3,6-month follow-up.
1470 nm DiLEP is safer than PKRP, with a smaller effect on sexual function, and it is comparable to the efficacy of PKRP, thus making it more suitable for elderly BPH patients.
