Objeactive To evalute the technique of three‐dimensional (3‐D) ultrasound imaging of the urethra and its application in both research and clinical practice. Patients and techniques The study involved 23 patients: 10 with benign prostatic hyperplasia, four with urethral strictures, three post‐insertion of prostatoc stents, one with bladder neck dyssuyner, three post‐transurethral resection of the prostate, and two with non‐urological conditions. A transrectal ultrasound scan was initially performed to acquire a series of images of the urethra. These images were then reconstruicted into a 3‐D format. Results The 3‐D image of the urethra could be rotated on screen and viewed from any angle. The image could also be sliced at any plane to reveal the sectional view. Conclusion This new tool represents a major advance in imaging techniques and promises to provide new knowledge in understanding the hydrodynamics of knowledge in understanding the hydrodynamics of the lower urinary tract. The precise geometry of the 3‐D urethra will also help in the design of new stents.
