A Systematic Review and Meta-analysis of Prostatic Urethral Lift for Male Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia.

Recently, prostatic urethral lift (PUL) is being used to treat lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). Although preliminary clinical studies on PUL are increasing, the long-term efficacy and safety of this procedure are still not well evaluated.

The objective of our study is to synthesize the existing literature evidence, and make a comprehensive and long-term systematic review for the PUL procedure.

A systematic search was performed from the electronic databases including PubMed, Embase, and OVID. The search period was up to January 1, 2020. Comprehensive retrospective and prospective studies on PUL were collected in accordance with specific inclusion and exclusion criteria. Pooled prostatic symptom scores, sexual health scores, and functional outcomes were calculated by using a fixed or random-effect model.

Nineteen articles meet our determined inclusion and exclusion criteria, and 11 independent patient series were included in the final analysis. Meta-analysis results indicated improvement after the PUL procedure, including International Prostate Symptom Score improvement of 9.73-12.16 points, BPH Impact Index improvement of 3.74-4.50 points, maximum flow rate improvement of 3.44-4.26 ml/s, and quality of life improvement of 2.20-2.55 points. Postvoid residual volume at most of the intervals was not significantly variable. Data regarding sexual function remained stable or improved slightly during the 24-mo follow-up period. Pooled estimates were largely heterogeneous except for sexual function.

PUL can continue to relieve prostatic symptoms for 24 mo without causing serious complications. The extremely important advantage of the PUL procedure is that it can preserve or slightly improve sexual function. Longer-term and more comprehensive clinical trials are still needed to further clarify the functional outcomes and cost effectiveness of PUL.

Prostatic urethral lift is an attractive option for selected patients who seek rapid and durable relief of lower urinary tract symptoms with complete preservation of sexual function.
