title: Durability and retreatment rates of minimal invasive treatments of benign prostatic hyperplasia: a cross-analysis of the literature.
abstract: BACKGROUND
  Transurethral resection of the prostate (TURP) has been the gold standard of the treatment of benign prostatic hyperplasia (BPH). In recent years there has been a significant shift in the treatment of BPH and guidelines emphasize minimally invasive surgery as a new treatment option. Minimal invasive technologies (MITs), such as transurethral microwave thermotherapy (TUMT), laser ablations, transurethral needle ablation (TUNA) have emerged as an alternative to the TURP.
  
  
  OBJECTIVE
  To assess the retreatment rates of the most commonly used minimal invasive techniques.
  
  
  METHODS
  Durability articles were selected by using defined search terms using PubMed as search engine.
  
  
  RESULTS
  Comparing to the overall retreatment rates of MITs the results show that TUMT, holmium laser enucleation of the prostate (HoLEP) and contact laser vaporization (CLV) are among the treatments with the lowest retreatment rates. Studies show no significant differences in retreatment rates between TUMT and TURP.
  
  
  CONCLUSIONS
  A review of the current literature, long term results and retreatment rates of MITs shows large variability in outcomes and retreatment rates. The true definition of a MIT remains unclear. High energy TUMT deserves reconsideration in clinical practices, due to low retreatment rates and the low need of anesthetics.
