Dr Miles Walkden is a consultant radiologist, specialising in Uroradiology and Interventional Oncology. He leads the renal ablation service at UCLH and the Royal Free.

He qualified from Guy’s and St Thomas’ London in 1997, initially training as a surgeon and gaining membership of the Royal College of Surgeons Edinburgh in 2002. He then went on to become a fellow of the Royal College of Radiologists in 2007 training in Interventional radiology at St Georges and UCLH.

Dr Walkden is now a dedicated uroradiologist with specific interests in renal ablation and andrological imaging including varicocele embolization and imaging for male infertility. He runs interventional radiology clinics allowing patients to be seen both before and after treatment thereby ensuring patients are always fully informed about procedures and their outcomes.

In his spare time Miles enjoys farming trying to improve his sheep shearing skills and embarrassing his four children.
