MP71-11 REZūM® SYSTEM WATER VAPOR TREATMENT FOR BENIGN PROSTATIC HYPERPLASIA: CHARACTERIZATION WITH MAGNETIC RESONANCE IMAGING AND 3D RENDERING

Rezum: a novel minimally invasive treatment for lower urinary tract symptoms secondary to benign prostatic hyperplasia. A review article

“…Only 2 patients showed an extraprostatic ablative lesion that was located at the bladder neck which were likely from vapor delivered mistakenly outside the transitional zone and this was resolved after 3 months. In their study, they reported a mean ablative lesion of 1.7 cm 3 for each injection [16]. Johnston et al reported a similar size reduction of 33% in their prospective cohort study on 210 patients [17].…”

“…One of the most appealing advantages of Rezum is the preservation of ejaculatory function that is commonly [14]. Convective thermal therapy using Rezum has shown a strong safety profile with minimal intra-operative complication as the produced thermal energy induces tissue ablation in the targeted areas respecting zonal boundaries [15,16]. The majority of post-operative complications reported from the previous studies are limited to Clavien-Dindo types I-II resulted from the acute inflammatory response to the ablated tissues leading to irritative LUTS that may last from 2 to 3 weeks as shown in Table 4 [14,17,[21][22][23][24][25].…”
