Abstract

Purpose: Lower urinary tract symptoms due to benign prostatic hyperplasia (LUTS/BPH) affects quality of life. Convective water vapor thermal therapy (CWVTT - Rezum) is a minimally invasive surgical treatment for LUTS/BPH which produces significant improvement of LUTS in men with prostates between 30cc-80 cc with minimal de-novo sexual dysfunction. However, outcomes across the prostate volume (PV) spectrum are incompletely described. We aim to elucidate the relationship between PV and outcomes post-CWVTT in men with LUTS/BPH.

Materials and methods: Patients undergoing CWVTT at a tertiary care center were included. The primary outcome was change in IPSS pre-CWVTT compared post-CWVTT between PV tertiles - small (≤38.5 cc), medium (38.5 - ≤55.6cc), and large (>55.6cc). Secondary outcome was time to a minimally clinically important difference (MCID) of 25% decrease in IPSS.

Results: 171 patients were divided into small (n=56), medium (n=54), and large (n=61) PV tertiles. The change in IPSS pre-operatively to 3-months was significant for all tertiles with mean difference of [-7.51 (-10.14, -4.83)], [-10.12 (-12.71, -7.53)], and [-11.72 (-14.14, -9.29)] for small, medium, and large PV, respectively (p=<0.001). In multivariable analysis, having diabetes was associated with increased IPSS after 3mo with average increase (95% CI) of [3.67 (0.23,7.11), p=0.037] compared to not having diabetes The median time (Q1, Q3) to -25% in IPSS for small, medium, and large PV were 16.1 (12.1, 17.5), 12.3 (7.1, 15.7), and 13.8 (10.8, 16.3) months, respectively. In multivariable analysis, medium PV had significantly increased incidence of 25% decrease compared to small PV [HR (95%CI): 2.10 (1.19, 3.72), p=0.011].

Conclusions: CWVTT results in significant and durable LUTS improvement across the prostate volume spectrum. All prostate volumes experience the same improvement in LUTS post-CWVTT. However, medium and large glands may improve more quickly than small glands.
