PD10-10 3-YEAR OUTCOMES OF SEXUAL FUNCTION AFTER WATER VAPOR THERMAL THERAPY (REZŪM®) AND MEDICAL THERAPY FOR TREATMENT OF LOWER URINARY TRACT SYMPTOMS DUE TO BENIGN PROSTATIC HYPERPLASIA (LUTS/BPH): RIGOROUS ASSESSMENT OF SEXUAL FUNCTION QUESTIONNAIRES WITH ITEM RESPONSE THEORY MODELING

37 interviews) and urinary and sexual outcome measures were similar across treatments.Notably, only 75% of ThuVARP patients underwent their allocation versus 98% for TURP, mostly due to ThuVARP equipment failure (18/51).Prostate cancer was detected incidentally less frequently after ThuVARP (13% vs. 5%, odds ratio 0.35, 95% CI 0.16 to 0.75) in an exploratory analysis.The ThuVARP operation took 20 minutes on average longer than TURP.Costs were similar at £4,185 for TURP and £67 higher for ThuVARP (95% CI -£353 to £486).CONCLUSIONS: ThuVARP mostly demonstrated similar outcomes to TURP.TURP was superior for Qmax, although both were clinically successful.ThuVARP may also detect less prostate cancer incidentally.The anticipated benefits of length of stay and bleeding for ThuVARP were equal to TURP.Overall, ThuVARP and TURP are effective BPO treatments, with minor clinical benefits favouring TURP, suggesting that TURP remains the "gold standard" operation.
