Learning robotic pyeloplasty without simulators: an assessment of the learning curve in the early robotic era

OBJECTIVE:

To analyze our experience and learning curve for robotic pyeloplasty during this robotic procedure.

METHODS:

Ninety-nine patients underwent 100 consecutive procedures. Cases were divided into 4 groups of 25 consecutive procedures to analyze the learning curve.

RESULTS:

The median anastomosis times were 50.0, 36.8, 34.2 and 29.0 minutes (p=0.137) in the sequential groups, respectively. The median operative times were 144.6, 119.2, 114.5 and 94.6 minutes, with a significant difference between groups 1 and 2 (p=0.015), 1 and 3 (p=0.002), 1 and 4 (p<0.001) and 2 and 4 (p=0.022). The mean hospital stay was 7.08, 4.76, 4.88 and 4.20 days, with a difference between groups 1 and 2 (p<0.001), 1 and 3 (p<0.001) and 1 and 4 (p<0.001). Clinical and radiological improvements were observed in 98.9% of patients. One patient presented with recurrent obstruction.

CONCLUSIONS:

Our results demonstrate a high success rate with low complication rates. A significant decrease in hospital stay and surgical time was evident after 25 cases.
