Professor Thomas Anthony McNicholas

Consultant Urologist


Specialises in

My practice covers all aspects of urology with particular emphasis on prostate cancer, other urinary cancers, stone disease, impotence, male infertility, vasectomy reversal and lower urinary tract problems and infection for both men and women.I provide significant numbers of second opinions and medico-legal cases. This is partly due to my involvement with specialist associations and NICE and contributions to national guidelines to improve standards of care.I developed the UroLift device from an idea in 2005 and performed the first treatments in the UK in 2011. I am the lead consultant in using UroLift at Spire Harpenden Hospital to treat an enlarged prostate.
