Waterjet Prostate Ablation

Sponsor: Chinese University of Hong Kong

Summary

Introduction Men with enlarged prostates commonly experience lower urinary tract symptoms and may go on to develop complications such as acute urinary retention (AUR). Surgery is the standard treatment option required to remove the enlarged prostates and to rectify such complications. Transurethral resection of prostate (TURP) was first performed over 80 years ago and is still regarded as the "gold standard" for the treatment of benign prostatic enlargement (BPE) in prostates between 30 and 80ml. While TURP results in an improvement in symptoms, perioperative morbidity and long-term complications can include postoperative bleeding, urinary retention, incontinence, urethral strictures, erectile dysfunction, and ejaculatory dysfunction. Aquablation, a novel minimally invasive water ablation therapy combining image guidance and robotics (AQUABEAM®, Procept BioRobotics, Redwood Shores, CA, USA) for the targeted and heatfree removal of prostate tissue is one of the efforts in the development of new technology in recent years to replicate the effectiveness of TURP and at the same time with an improved safety profile. In this study, investigators plan to evaluate the feasibility and safety of Aquablation in the management of AUR secondary to BPE. Method 20 participants are expected in this study. After patients consent to participate in the study, they will go through Aquablation under general anaesthesia or spinal anaesthesia. The ablation is delivered by transurethral means. After the procedure, subject is expected to go home on the following day. Subject will be assessed 3 months and 6 months after the procedure. Follow-up assessment includes blood tests, prostate ultrasound and urodynamic study.
