Summary

Intracorporeal suturing and knot tying during robotic prostatectomy and laparoscopic and robotic renal surgery have historically been considered the most technically challenging and time consuming aspects of these procedures. With improved operative technique as well as the use of innovative surgical devices, vascular control during these surgeries is often less cumbersome as compared with traditional techniques. Current standard methods of hemostasis include the use of clips, of which the most popular design is the Hemolock, a locking, nonabsorbable plastic clip, or the use of the very expensive endomechanical stapler. Unfortunately while they are associated with time savings in the operating room, there is a great deal of disposable costs associated with these various devices as well as a not insignificant device malfunction rate reported in the literature. The aim of this case-controlled study is to evaluate the Aesculap U-clip device compared to our current technique of vascular control using the Teleflex Hemolock clip device during minimally invasive genitourinary surgery.

Conditions

• Prostatectomy
• Nephrectomy
• Laparoscopy
• Robotics

Interventions

Type	Name	Description
DEVICE	Teleflex HemoLock clip	Patients randomized to the Aesculap U-clip device or the HemoLock clip will undergo their respective surgery (robotic prostatectomy and laparoscopic and robotic renal surgery) as per standard protocols. During the surgical procedure, when primary vascular control is warranted the appropriate clip to which the patient has been randomized will be utilized. Immediate assessment of the vascular pedicle will subsequently occur; if hemostasis is not adequate, additional clipping, endomechanical stapling or suture ligation will then be performed as necessary.
