Abstract/OtherAbstract:
INTRODUCTION: High Intensity Focused Ultrasound (HIFU) ablates benign prostatic tissue in a minimally invasive manner with low morbidity. The safety and effectiveness of treating of benign prostatic hypertrophy (BPH) with HIFU using 3 different protocols are reported. METHODS: Forty six male patients with a mean age of 65 (range 47-84) were treated using the Sonablate HIFU device (Focus Surgery, Indianapolis IN) with 3 different protocols at 3 centres (LDS n=20, PJP n=12, RWC n=14). Baseline and outcome measures included AUA symptom score, peak urinary flow rate (Qmax) and quality of life (QOL) score. Early and long term complications were recorded. RESULTS: At 12 months post-HIFU, patients showed improvements in AUA symptom scores of 35% (LDS), 43% (PJP) and 59% (RWC). Qmax improved by 30% (LDS), 37% (PJP) and 63% (RWC). QOL scores improved by 63% (LDS) and 58% (RWC). Minor complications included hematospermia (13%), mild to moderate hematuria (9%), acute retention (4%), perineal pain (11%) and epididymitis (9%). Recatheterization occurred in up to 16% of patients. Eleven patients in the LDS and PJP series required a transurethral resection of the prostate (TURP) for symptoms of urinary obstruction after HIFU treatment. There were no TURP's following HIFU in the RWC series. CONCLUSIONS: HIFU is safe, produces acceptable complications and effectively relieves BPH symptoms.
