Mr Paras Singh

Consultant Urologist


Mr Paras Singh qualified from Institute of Medical Sciences, Varanasi, India. He moved to the United Kingdom for his higher surgical training in Urology. He was awarded an MD at Lancaster University for his work on racial differences in the metabolising enzymes in the human prostate.

Mr Singh received his urology training in London working at University College Hospital, Royal Free Hospital and Whipps Cross Hospital. He was appointed as a consultant urological surgeon in 2014.

He has a broad general urology practice with special interests in benign prostatic disease (medical management and minimally invasive therapy – TURP / TURiS), stone disease, prostate cancer diagnostics and urothelial cancers (endoscopic management of bladder cancer and upper tract cancer). He introduced MRI fusion prostate biopsies at the Royal Free London NHS Foundation Trust. He is a core member of the bladder cancer and prostate cancer multi-disciplinary teams at the Royal Free London NHS Foundation Trust.

Mr Singh is the principal investigator in several prostate and bladder cancer trials.

Originally from Nepal, he is married with two children. His daughter was the youngest Olympian at Rio 2016 at the age of 13. He is actively involved with several Nepalese organisations in the UK and with charity work in Nepal.
