Nerve Sparing Prostatectomy clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT01794936 Terminated - Prostate Cancer Clinical Trials

Pilot Study of VTI Doppler Probe Use to Identify Neurovascular Bundle During Prostate Surgery

Start date: August 2011
Phase: N/A
Study type: Interventional

This study is designed to evaluate the use of a disposable laparoscopic Doppler probe in robotic assisted prostatectomies. The Vascular Technology, Inc. (VTI) laparoscopic probe is simply a sterile, disposable Doppler probe that can be inserted through a laparoscopic trocar and placed on structures to determine if there is vascular flow demonstrating an audible pulse. During robotic-assisted prostatectomy, identification of vasculature is critical in order to prevent hemorrhage and effectively treat the underlying pathology. The investigators routinely utilize a combined Doppler ultrasound laparoscopic probe to identify vasculature during renal surgery, but Doppler ultrasound usage has not been adopted for prostatic surgery. From a mechanical standpoint, these combination probes differ from the VTI probe in that they are approximately 2 times the diameter of the VTI probe, and the portion of the probe utilized for imaging much longer and on the side of the device. The VTI probe is much narrower, and the portion of the probe utilized for vessel identification is at the tip of the probe. For robotic-assisted prostatectomy, patients will be randomized to VTI laparoscopic Doppler System to identify pedicles and neurovascular bundles (NVB) or to robotic-assisted laparoscopic prostatectomy with no Doppler probe, which is the current standard of care.
