Purpose
Rezūm is the latest developed minimally invasive treatment for benign prostatic hyperplasia (BPH). We aimed to carefully assess the functional outcomes of patients treated with Rezūm for BPH.
Methods
We prospectively followed 135 consecutive patients treated by Rezūm at 5 institutions from June 2019 to August 2020. The International Prostate Symptom Score (IPSS), International Consultation on Incontinence Questionnaire-Short Form (ICIQ-UI SF), the Overactive Bladder Questionnaire-Short Form (OAB-q SF) score, the International Index of Erectile Function (IIEF-5) and questions 9 and 10 to assess ejaculatory dysfunction were recorded.
Election criteria were age > 18, no prior prostate interventions, IPSS ≥ 13, post-void residual ≤ 250 mL, prostate volume between 30 and 120 cc.
Results
The median operative time was 10.5 (IQR 8.7–15) min. All patients were dismissed few hours after surgery with indwelling urinary catheter that was removed after a median of 7 (IQR 7–10) days. A significantly decrease of IPSS from baseline at first (
p
= 0.001) and third (
p
< 0.0001) month after surgery was reported. No difference was reported in terms of ICIQ-UI SF score postoperatively. A mild reduction of the OAB-q SF score was reported at 1 month from surgery (
p
= 0.06) that turned significant at 3 months postoperatively (
p
< 0.0001). A slight but statistically significant increase of the IIEF-5 score was reported from baseline at 6 months (
p
= 0.04). Postoperatively, patients reported a significantly decrease of ejaculatory dysfunction after alpha-blocker interruption.
Conclusion
Rezūm treatment is a feasible minimally invasive option for patients with BPH symptoms and showed optimal early functional outcomes.
A thorough analysis of the tank quality factor in LC oscillators using switched capacitor banks has been carry out taking into account the contribution of the switched capacitances in the off state. Analysis results, confirmed by circuit level simulations, clearly show that the contribution of the switched capacitances in off state strongly affects the quality factor of the capacitor bank, and thus of the tank, increasing it. General expressions of the quality factor of useful one-port reactive networks are also presented
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
