Objective: To investigate the feasibility, safety and efficacy of holmium laser enucleation of the prostate (HoLEP) in the re-treatment setting (salvage HoLEP) and compare it to the primary HoLEP procedure that is commonly used for the treatment of benign prostate hyperplasia (BPH).
Materials and methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, PubMed, Scopus, and Cochrane databases were systematically screened, from inception to 8 August 2022. Other potentially eligible studies were retrieved using the reference lists of the included studies. Retrospective and prospective studies, both comparative and non-comparative, were included.
Results: A total of 12 studies met the inclusion criteria and were included in the final qualitative synthesis. One study was prospective comparative (non-randomised), seven studies were retrospective comparative, and four studies were retrospective non-comparative or case series. In total, 831 patients were treated with salvage HoLEP in the above studies. Previous intervention before salvage HoLEP ranged among studies. The most commonly performed was transurethral resection of the prostate. Intraoperative parameters of salvage HoLEP were comparable with those reported during primary HoLEP, while all postoperative outcomes were significantly improved after salvage HoLEP and were similar with those observed after primary HoLEP. No major complications were noted after salvage HoLEP according to Clavien-Dindo classification.
Conclusions: Salvage HoLEP after previous interventions for treating recurrent or residual BPH is a feasible, safe, and efficient procedure. Data presented in selected studies, along with the holmium laser's physical properties to resect more tissue and to dissect along the true anatomical plane of BPH, render HoLEP an ideal salvage treatment modality for recurrent or residual BPH symptoms.
