Transrectal Ultrasound (TRUS) in Finding Tumors During Robotic-Assisted Laparoscopic Surgery

Mechanically-Manipulated Transrectal Ultrasound (TRUS) During Robotic-Assisted Laparoscopic Prostatectomy (RALP)

This pilot clinical trial studies mechanically-manipulated ultrasound in finding tumors during robotic-assisted surgery in patients with prostate cancer. Diagnostic procedures, such as ultrasound, may help find prostate cancer and find out how far the disease has spread during surgery

PRIMARY OBJECTIVES: I. To assess the feasibility and limitations of using a mechanically-manipulated transrectal ultrasound (TRUS) probe for TRUS evaluation during a da Vinci robotic-assisted laparoscopic prostatectomy (RALP). II. To collect TRUS evaluation data during RALP to guide us in deciding whether and how the mechanical manipulation of the TRUS probe will allow sufficient clarity of ultrasound imaging. OUTLINE: Patients undergo TRUS during RALP. After the completion of study treatment, patients are followed up at 7 days.

Number of patients who have negative margins when a TRUS probe is used during RALP procedure without introducing additional complications.

Inclusion Criteria: Undergoing Robotic Assisted Laparoscopic Prostatectomy Exclusion Criteria: Known or discovered rectal pathology Bleeding hemorrhoids Rectal stenosis Any prior rectal surgeries Prior rectal radiation Any known rectal disease
