Emerging minimally invasive transurethral treatments for benign prostatic hyperplasia: a systematic review with meta-analysis of functional outcomes and description of complications.

Several minimally invasive surgical procedures have been proposed as alternative therapies for benign prostatic hyperplasia (BPH). The present systematic review aimed to describe the functional outcomes and complications of emerging minimally invasive transurethral treatments for BPH.

A comprehensive bibliographic search on the MEDLINE and Cochrane Library databases was conducted. No chronological restriction was applied. Retrospective and prospective primary studies were included. A meta-analysis of IPSS, IPSS-QoL, Qmax, and PVR was performed. Data on adverse events were presented narratively.

A total of 18 studies were included. Thirteen papers were eligible for the meta-analysis. iTIND, Rezūm, and Aquablation were associated with a significant improvement in IPSS (p<0.001), IPSS-QoL (p<0.001), and Qmax (p<0.001) compared to baseline. A significant reduction of PVR from baseline was found with Rezūm (p<0.001) and Aquablation (p<0.001) but not iTIND (p=0.22). A significant difference in IPSS, IPSS-QoL, and Qmax was shown in favor of Aquablation compared to Rezūm and iTIND (p<0.001). Rezūm and iTIND were mainly associated with mild to moderate adverse effects. Hematuria or bleeding was reported in all studies regarding Aquablation (0.8%-26%), the need for transfusion or intervention for bleeding varied between 1.8% and 9%.

Aquablation, Rezūm, and iTIND significantly improve urinary functional outcomes compared to baseline; however, Aquablation would seem to lead to better functional results compared to the other procedures. Rezūm and iTIND appear to have an excellent safety profile, while Aquablation would seem to expose patients to a nonnegligible risk of bleeding.
