Feasibility of a transurethral ultrasound applicator for coagulation in prostate.

Transurethral resection of the prostate (TURP) is the surgical method routinely used in clinics to treat benign prostate hyperplasia (BPH). The purpose of this work is to demonstrate the feasibility of a transurethral ultrasound (US) applicator based on a miniature US flat transducer to coagulate prostatic tissues. Rabbit liver was found to comply well with human prostate.
