• In 2014, Dr Sim was awarded a fellowship at the Eberhard Karls University of Tuebingen (Germany) with Prof Christian Schwentner, sub-specialising in Endourology, Laparoscopic and Robotic Surgery. He has a keen interest in management of urinary stone diseases and minimally invasive surgeries for bladder, kidney and prostate. He is trained in sub-specialized procedures such mini PCNL (Percutaneous Nephrolithotomy), wide range of laparoscopic surgeries such as laparoscopic radical nephrectomy, nephroureterectomy, partial nephrectomy, pyeloplasty, retroperitoneal lymph node dissection (RPLND), IVC thrombectomy as well as robotic partial nephrectomy, prostatectomy and radical cystectomy with special interest in intracorporeal urinary reconstruction. Since returning from his fellowship, he has been advancing minimally invasive surgeries and pioneering surgical techniques such as supine PCNL, ECIRS, Video Endoscopic Inguinal Lymphadenectomy (VEIL) and zero ischaemic partial nephrectomy with super-selective clamping.
