Current role of robot-assisted pyelolithotomy for the management of large renal calculi: A contemporary analysis

Background and Purpose: The scope of robot-assisted surgery continues to expand with the application of these systems to management of large upper-tract urinary stones, with or without concomitant pyeloplasty. The known advantages of the robot-assisted approach, including enhanced optics, dexterity, wristed instrumentation, and ergonomics, can facilitate complex reconstruction of the collecting system, including uteropelvic junction repair. With the favorable outcomes of contemporary robot-assisted pyeloplasty series, robot-assisted applications have been translated to pyelolithotomy with or without concomitant upper-tract reconstruction. The early results of robot-assisted lithotomy reveal the procedure is a safe and efficacious approach for patients with large renal stones; nevertheless, the technique has met limited success in cases of large staghorn calculi. Our purpose was to evaluate the current role of robot-assisted pyelolithotomy for the management of large renal calculi. Conclusion: Given the known advantages of the robotic system in conjunction with its reconstructive capabilities, the applications of robot-assisted pyelolithotomy, although encouraging, warrant further longitudinal, multi-institutional investigation. This technique is in its early stage of implementation and randomized trials that compare robot-assisted outcomes with other minimally invasive techniques are needed to define clinical efficacy as it pertains to subsets of patients with variable stone size, location, and consistency.
