Dr. Ashutosh (Ash) K. Tewari

Dr. Tewari chairs the Milton & Carroll Petrie Department of Urology at the Icahn School of Medicine and directs Mount Sinai’s Precision Urology and Robotic Prostatectomy Programs. His group integrates multiparametric MRI, genomics, and prostate-specific membrane antigen (PSMA) PET to tailor surgical planning and match systemic therapy to tumour biology. Patients discussed at weekly tumour boards benefit from consensus on oncologic control, functional preservation, and cost-effectiveness.

 

A pioneering robotic surgeon, he described the “hood,” “tunnel,” and “NeuroSAFE” techniques, all designed to protect continence and erectile function without compromising margin status. Peer-reviewed series now exceeding ten-thousand cases document continence recovery above national benchmarks and positive-margin rates below ten per cent. Current trials test real-time fluorescence to identify cavernous nerves and evaluate circulating-DNA clearance as a surrogate for biochemical recurrence. 

 

Dr. Tewari also leads a bench program that examines androgen-receptor splice variants, metabolic re-wiring after focal therapy, and immune-checkpoint resistance. Collaborative grants with Cold Spring Harbor Laboratory and the Broad Institute support this work, underscoring a career that couples surgical innovation with mechanistic discovery.
