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

Condition Intervention
Prostate Cancer Procedure: ultrasound imaging Procedure: robot-assisted laparoscopic surgery

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Mechanically-Manipulated Transrectal Ultrasound (TRUS) During Robotic-Assisted Laparoscopic Prostatectomy (RALP)

Further study details as provided by University of Southern California:

Primary Outcome Measures:
  • Number of patients who have negative margins when a TRUS probe is used during RALP procedure without introducing additional complications. [ Time Frame: 7 days post-RALP ]

Enrollment: 11
Study Start Date: October 2011
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Diagnostic (TRUS)
Patients undergo TRUS during RALP.
Procedure: ultrasound imaging
Undergo transrectal ultrasound
Other Names:
  • ultrasonography
  • ultrasound
  • ultrasound test
Procedure: robot-assisted laparoscopic surgery
Undergo robotic-assisted laparoscopic prostatectomy

Detailed Description:
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.
