[Minimally-Invasive Surgical Techniques (MIST): Shedding Light on the Mist]

As life expectancy increases and there is growing demand for BPH treatments, innovative technologies have been developed, allowing for swift recovery, symptom relief, low complication rates, and the possibility of performing procedures on an outpatient basis, often under local anaesthesia. This review aims to describe the outcomes of newly developed minimally-invasive surgical therapies (MIST) for BPH treatment in terms of functional voiding parameters and sexual function. These therapies are categorized into primarily ablative (Aquablation [Aquabeam]), non-ablative (Prostatic Urethral Lift (PUL, Urolift), temporary implantable devices [iTind]), and secondarily ablative procedures (convective water vapor ablation, Rezum, Prostate Artery Embolization [PAE]). All MIST technologies have advanced the medical care of patients with BPH while preserving ejaculation. However, there is a shortage of long-term data specifically addressing re-intervention rates and the preservation of functional voiding parameters. Although there is promising data from regulatory trials and randomized studies, all MIST therapies are potentially associated with severe complications. Patients considering such methods must be thoroughly informed about their inferiority compared with established transurethral procedures like TUR-P and enucleation.
