Intraoperative and postoperative outcomes of thulium laser enucleation versus bipolar resection in the transurethral treatment of benign prostatic hyperplasia: a meta-analysis.

Abstract

To compare the intraoperative and postoperative outcomes of thulium laser enucleation of the prostate (ThuLEP) vs bipolar transurethral resection of the prostate (B-TURP) in treating patients with benign prostatic hyperplasia (BPH). Clinical trials of ThuLEP and B-TURP in treating BPH were searched systematically by using PubMed, Cochrane Library databases, and EMBASE (until May 2021). The Preferred Reporting Items for Systematic Reviews and Meta-analyses checklist was followed. The datum was calculated by Review Manager version 5.3.0. Four articles including 782 patients were studied in this analysis. The analysis discovered that there was no significant difference in operative time and percentage of tissue removed between ThuLEP and B-TURP. But the intraoperative irrigated volume and postoperative hemoglobin (Hb) decrease in the ThuLEP group was significantly less compared with the B-TURP group. The catheterization time and hospitalization duration in the B-TURP group was significantly longer than that in the ThuLEP group. Compared with those before treatment, the micturition indexes of the two groups improved significantly. But no significant difference was identified between ThuLEP and B-TURP for the variation of international prostate symptom score, quality of life, maximum flow rate, and post-void residual. By analyzing the postoperative complications, there were no significant discrepancies between ThuLEP and B-TURP in the incidence of blood transfusion, recatheterization, transient incontinence, bladder neck contracture, and urethral stricture. The micturition indexes and clinical symptoms were significantly improved after ThuLEP and B-TURP for patients with BPH. However, ThuLEP was more effective than B-TURP in terms of intraoperative irrigated volume, postoperative Hb decrease, catheterization time, and hospitalization duration.
