About
Ananthakrishnan Sivaraman is a urological surgeon and researcher whose work has fundamentally shaped the modern evaluation and technical refinement of robot-assisted radical prostatectomy (RARP) for prostate cancer. His most influential contribution is the introduction of the "pentafecta" concept — a comprehensive five-criterion outcomes framework that expanded upon the traditional trifecta by incorporating continence, potency, oncological control, absence of complications, and anastomotic integrity, now widely adopted in surgical reporting worldwide (336 citations). Sivaraman has made substantial technical contributions to improving functional recovery after RARP, including pioneering modified posterior rhabdosphincter reconstruction to enhance early continence (181 citations) and developing anatomic grading systems for nerve sparing (135 citations). His large-scale multi-institutional analyses, including an examination of positive surgical margins across 8,418 procedures, have provided critical benchmarks for the field (149 citations). Drawing on extensive single-surgeon and multi-institutional datasets, his research consistently bridges surgical technique with patient-centered outcomes. With a body of work exceeding 1,100 cumulative citations, Sivaraman stands as a key figure in advancing the evidence base underpinning minimally invasive urological oncology.
