A novel "no-touch" robot-assisted laparoscopic technique facilitates ureteral reconstructive surgery

Abstract

Objectives: One of the current limitations of robotic surgery is the lack of haptic feedback. In order to overcome this drawback we developed a "No-Touch" (NT) technique utilizing the distal portion of a feeding tube to intubate and manipulate both the ureter and the renal pelvis during anastomosis. Materials and Methods: Ureteral spatulation and pelvic reduction were performed as necessary. An 8 centimeter distal end segment of a 3 to 5 French feeding tube was used to intubate and manipulate the lumen of the proximal ureter and renal pelvis or recipient ureter during anastamosis. Manipulation of the discarded segment of the pelvis served as a handle to control and limit tissue handling. The NT technique allows for precise suture placement and prevented inadvertent backwall suture placement, thus ensuring luminal patency. No nephrostomy tubes or ureteral stents were utilized during these procedures. Patients were followed every three months for the first year with renal ultrasonography. Review of operative videos and surgical results was performed. Results: Ten robotic pyeloplasties, one robotic pyeloureterostomy, and one robotic distal ureteroureterostomy were performed using the NT technique. No backwall suture placements, tissue crush or crimping injuries or occurred in any case. There were no intraoperative or post-operative complications. Resolution of hydronephrosis and symptoms was demonstrated in all patients after post-operative examination and ultrasonography. Conclusions: A "No-Touch" robotic technique utilizing the distal blunt end of a feeding tube is a safe, effective, and inexpensive adjunct tool that minimizes tissue handling in robot-assisted laparoscopic surgery.

“…Owing to the lack of haptic feedback with the robotic system, the surgeon risks crushing and devitalizing tissue and potentially compromising one's repair. We use a feeding tube segment to facilitate the anastomosis and to minimize tissue handling [Swords et al 2011]. We have chosen to perform our anastomosis with interrupted sutures.…”
