Single port (SP) robotic pyeloplasty in a pediatric patient

We began using the da Vinci single port (SP) robot for pediatric urologic surgeries at our institution due to limited access to the multiport robot. Availability of this technology has allowed us to schedule cases in a timelier fashion and increase access to minimally invasive urologic surgery for children in our area. Here, we report our technique for transperitoneal SP robotic pyeloplasty in the case of a 7 year-old boy with left ureteropelvic junction obstruction. Our technique was refined over a series of 10 patients under the age of 18. Highlights of the SP RALP technique include one 3 cm, concealed incision over the pubic tubercle, gentle frog leg positioning and burping of the boom to create optimal angle for robotic docking, and use of a "floating dock" to obtain 10 cm distance from target anatomy which is essential in smaller pediatric patients. SP pyeloplasty is safe and feasible in children and offers a concealed single incision alternative to the multiport approach.
