VTI’s Drop-In Doppler probe is used to facilitate identification of the vessels in the renal hilum
Urologists performing robotic or laparoscopic renal surgery appreciate the many benefits provided by VTI’s 8 MHz Drop-In Doppler probe. Surgeons choose VTI’s Drop-In Doppler to guide dissection & isolation of the renal hilum and aberrant vasculature during these complex procedures. With over 25% of patients presenting with variations in their renal vascular anatomy, the VTI Drop-In Doppler probe provides a SOUND SOLUTION to the challenges of robotic renal surgery.
During robotic surgery, the Drop-In Doppler is placed into the operative field through the assistant port. It can then be manipulated by the console surgeon via the robotic instruments. Unlike intraoperative ultrasound, the VTI flexible Drop-In Doppler fits into small spaces and provides precise, pinpoint localization of the vasculature. It is ideally suited for facilitating hilar dissection and for confirming ischemia after clamping.
Surgical Procedures
- Robotic or laparoscopic partial nephrectomy
- Robotic or laparoscopic radical nephrectomy
- Robotic or laparoscopic pyeloplasty
Doppler Uses
- Facilitates dissection of the renal hilum, especially in cases with significant overlying fat/scarred tissue
- Facilitates identification of aberrant vasculature, including duplicated vessels and early branching
- Confirms adequate ischemia after clamping
- Facilitates identification of crossing vessels in pyeloplasty
Clinical Studies Demonstrate:
Use of Doppler probe during minimally invasive partial nephrectomy:
- Minimizes risk of significant bleeding1
- Leads to a change in operative management2
- Significantly reduces hilar dissection time1
Use of Doppler during minimally invasive renal surgery provides fast, efficient identification of the renal hilum without an added learning curve3
