MRI Evaluation of Patients Before and After Interventions for Benign Prostatic Hyperplasia: An Update.

Transurethral resection of the prostate is the most commonly performed procedure for the management of patients with lower urinary tract symptoms attributed to benign prostatic hyperplasia (BPH). However, in recent years, various minimally invasive surgical therapies have been introduced to treat BPH. These include laser-based procedures such as holmium laser enucleation of the prostate and photoselective vaporization of the prostate as well as thermal ablation procedures such as water vapor thermal therapy (Rezūm), all of which result in volume reduction of periurethral prostatic tissue.

Tissue contraction caused by radiofrequency and microwave ablation: a laboratory study in liver and lung.

Purpose: To determine the amount of tissue contraction during radiofrequency (RF) and microwave ablation.

Materials And Methods: Markers were inserted into explanted bovine liver and lung 10 mm (inner), 20 mm (middle; not used in lung), and 30 mm (peripheral) diametrically around an ablation applicator. Aside from unablated controls, RF and microwave ablations 25-30 mm in diameter were then created and sectioned to measure the distance between markers (n = 12, liver RF; n = 8, other).
