About me

I have been a qualified doctor for over 24 years and a qualified consultant urologist for over 11 years. I have had comprehensive training and experience in urology and I cover the majority of adult urology.

I completed training in London, Bristol and the Cambridge training rotation. I have particular expertise in urological diagnostics and set up one of the first urology "one stop" clinics in the country, a successful project that was featured in the annual hospital awards and significantly reduced waiting times. In addition to general urology, I also specialise in minimally invasive treatments to improve outcomes and I have successfully introduced several new treatments and specialities into my department.

During 24 years of practice I have performed over 14,000 urological procedures including, 1,200 prostate biopsies (the last 780 of which have been trans-perineal), 690 bladder cancer resections, 325 circumcisions, 560 surgeries to relieve benign prostatic obstruction and 400 ureteroscopies.

I work in one of the highest volume centres for laser prostate surgery in the UK. I have personally performed well over 200 holmium laser enucleations of the prostate (HoLEP) and I train senior trainees from all around the country who come to learn this technique in our unit.

I am the lead clinician for urological cancer in our department and I led the urological cancer response to Covid. I have also contributed to several regional cancer guidelines. I am a GMC approved trainer and I teach on several national urology courses. I continue to maintain an active interest in clinical research and I have been local investigator for several national trials in recent years. I have published extensively in the urological literature and I have given numerous presentations around the world on urological topics. I am the recipient of 3 clinical excellence awards and numerous academic prizes and grants for my work, including a British Urological Foundation Fellowship.
