Urinary Tract Calculi VI: Surgical Management

802
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Summary

A new robotic platform simplifies holmium laser enucleation of the prostate (HoLEP) by improving maneuverability and reach. This innovation aims to overcome the perceived learning curve associated with HoLEP procedures.

Area of Science:

  • Urology
  • Robotics
  • Minimally Invasive Surgery

Background:

  • Holmium laser enucleation of the prostate (HoLEP) offers clinical benefits but faces slow adoption due to a steep learning curve.
  • A need exists for improved tools to facilitate HoLEP procedures in urology.

Purpose of the Study:

  • To design and develop a transurethral endoscopic robotic platform to enhance HoLEP.
  • To evaluate the platform's maneuverability and effectiveness in a simulated and cadaveric setting.

Main Methods:

  • Development of a novel transurethral, concentric tube robotic platform for HoLEP.
  • Magnetic tracking experiments comparing robot end-effector movements to rigid endoscopes.
  • Testing on a HoLEP simulator and human cadaveric prostate for workspace assessment.

Main Results:

  • The robotic platform demonstrated a 65% improvement in reachable area compared to rigid endoscopes without tissue deformation.
  • Successful maneuvering within the prostatic urethra and complete prostate lobe enucleation on both simulator and cadaver models.
  • The robot's end effectors produced complex movements suitable for HoLEP tasks.

Conclusions:

  • A novel concentric tube robotic platform was successfully developed for HoLEP.
  • The platform shows potential to improve the ease and accessibility of performing HoLEP procedures.
  • This robotic system may help overcome adoption barriers related to the HoLEP learning curve.
