For decades, Transurethral resection of the prostate (TURP) was the gold standard surgical intervention for small and moderate prostates, however it has high morbidity and prolonged hospital stay. In contrast to monopolar TURP (M-TURP), where prolonged resection carries the risk of transurethral resection (TUR) syndrome, bipolar transurethral resection of prostate (B-TURP), especially in large prostates was a promising procedure for urologists, but unfortunately, the morbidity rate of B-TURP remains high \[4\]. Therefore, newer minimally invasive procedures have been introduced to provide alternative surgical options to TURP.
Rezūm is a radiofrequency made water vapour thermal treatment. It has recently been added to the international guidelines as a choice for medical treatment resistant lower urinary tract symptoms (LUTS). The AUA and Canadian Urological Association (CUA) guidelines now add water vapour therapy as a treatment option for BPH patients with small prostate size \<80 gm and for those wishing to maintain antegrade ejaculation. While they still offer no clear recommendation to Rezūm use for those with large prostates. Early studies on this topic have found out promising results.
