Comparison between thulium laser vapoenucleation and plasmakinetic resection of the prostate in men aged 75years and older in a real-life setting: a propensity score analysis.

Abstract

Urologists may hesitate to offer transurethral resection of the prostate (TURP) because of increased morbidity in elderly patients. We aimed to compare data on postoperative outcomes of elderly men undergoing bipolar transurethral resection of the prostate (B-TURP) as compared to thulium laser vapoenucleation of the prostate (ThuVEP). We retrospectively reviewed data of all patients aged ≥ 75years who underwent benign prostatic hyperplasia surgery. Differences between interventions were estimated using propensity scores (PS) to adjust for different patients characteristics. Between 2017 and 2020, 275 men were included in the analysis. Propensity score retrieved 65 patients in each group. Median age was 78 (4) years in B-TURP group and 78 (6) in ThuVEP group. Median prostate volume was 63 (35) ml and 54 (24) ml in B-TURP group and ThuVEP group, respectively. Only American Society of Anesthesiologists score was significantly higher in ThuVEP group (p = 0.006). Median operation time, catheterization time, and hospital stay were similar in both groups (55min, 2 and 3days). Overall, 84.6% of men had no complications, with no significant differences between the groups (p = 0.234). Only one patient in B-TURP group experienced a Clavien grade IIIb complication. By 1year, there were a statistically significant differences in International Prostate Symptom Score (p = 0.000) in favor of B-TURP group and in maximal urine flow rate (p = 0.000) in favor of ThuVEP group. Both procedures showed excellent functional improvements one year after surgery with a low rate of major complications in men aged ≥ 75years with small-to-medium sized prostates.
