He is experienced in open, laparoscopic, and robotic minimally invasive surgery for the management of urologic tumors, including nerve-sparing laparoscopic and robot- assisted radical prostatectomy, laparoscopic and robotic nephrectomy and partial nephrectomy, and robotic radical cystectomy.

A particular expertise of his is the robotic extraperitoneal (or retroperitoneal) approach to the prostate and kidney for patients with prostate or kidney cancer. This approach, which avoids entry into the abdominal cavity, is ideally suited for patients that have had prior abdominal or inguinal operations (e.g. hernia repairs, appendectomy, colectomy) or who have inflammatory conditions (e.g. Crohn’s disease, ulcerative colitis, diverticulitis) that might make an abdominal robotic approach more hazardous.

Dr. Pavlovich is accepting new patients and is delighted to offer second opinions regarding the treatment of any urologic malignancy.
