Safety and effect of transurethral holmium laser enucleation of the prostate versus bipolar transurethral plasmakinetic prostatectomy for benign prostatic hyperplasia: A meta-analysis / 中华男科学杂志

ABSTRACT

<p><b>Objective</b>To evaluate the safety and effect of transurethral holmium laser enucleation of the prostate (HoLEP) in comparison with bipolar transurethral plasmakinetic prostatectomy (TUPKP) in the treatment of benign prostatic hyperplasia (BPH).</p><p><b>METHODS</b>We searched the databases of PubMed, SCI, Ovid, The Cochrane Library, CNKI, CBM, VIP, and Wangfang Data for controlled clinical trials about HoLEP versus TUPKP in the treatment of BPH published up to April 2016. The studies were screened according to the inclusion and exclusion criteria, the data extracted, and their quality evaluated by 2 reviewers independently, followed by a meta-analysis using the RevMan 5.3 software.</p><p><b>RESULTS</b>A total of 7 studies were included, involving 2031 cases. In comparison with TUPKP, HoLEP showed significantly longer operation time (WMD = 24.61, 95% CI 11.88, 37.34, P lt; 0.001), shorter hospital stay (WMD =－1.91, 95% CI －3.74, －0.07, P = 0.04), shorter bladder irrigation time (WMD = －21.50, 95% CI －34.95, －8.06, P = 0.002), shorter catheter-indwelling time (WMD = －27.60, 95% CI －48.17, －7.03, P = 0.009), less hemoglobin loss (WMD = － 0.42, 95% CI －0.78, －0.07, P = 0.02); lower postvoid residual urine (PVR) at 3 months (WMD = －3.35, 95% CI －4.46, －2.23, P<0.001) and 6 months after surgery (WMD =－1.11, 95% CI －2.18, －0.05, P = 0.04); higher maximum urinary flow rate (Qmax) (WMD = 0.42, 95% CI 0.04, 0.80, P = 0.03) and fewer urinary tract irritation symptoms (OR =0.58, 95% CI 0.41, 0.81, P = 0.002) at 12 months after surgery. No statistically significant differences were found between the two groups in the volume of resected tissue, serum sodium reduction, urethral stricture, erectile dysfunction, retrograde ejaculation, or transient urinary incontinence (P>0.05), or in the improvement of the quality of life (QoL) at 1, 3 and 12 months, International Prostate Symptom Score (IPSS) at 1, 3, 6 and 12 months, Qmax at 1, 3 and 6 months, or International Index of Erectile Function-5 (IIEF-5) at 6 months after surgery (P>0.05).</p><p><b>CONCLUSIONS</b>HoLEP is preferred to TUPKP in clinical application for its advantages of higher Qmax at 12 months after surgery, lower PVR at 3 and 6 months, higher peri-operative safety, faster recovery, and fewer urinary tract irritation symptoms. However, for the quantity and quality limitations of the included publications, our findings are to be further supported by large-sample, multi-center, and high-quality prospective controlled clinical studies.</p>
