Interventional
Description of intervention(s) / exposure
This study aims to develop and implement a method of displaying live internal anatomical data on head-mounted display (Microsoft HoloLens system) using augmented reality technology and to use this data to successfully achieve renal access during a Percutaneous Nephrolithotomy.

Pre-oeprative CT images of the patient's urinary system will be used to construct the 3D model which will be projected onto the HoloLens system. The HoloLens system will only be worn at time of initial entry into the patient's renal calyx during percutaneous nephrolithotomy (PCNL).

The procedure will be carried out by Dr Devang Desai, MBBS, FRACS (Urology), Consultant Urologist, at Toowoomba Base Hospital. The procedure will not deviate from a standard PCNL except for the use of the HoloLens system in place of standard image intensifier fluroscopy that is used to typically gain entry into the renal calyx. Standard fluroscopy will be available for use if required. Data concerning success recorded at time of procedure via operator survey. The project aims to be a proof-of-concept that this approach is feasible, while offering initial data on potential expectations of outcome in future studies.

Outcomes
Primary outcome [1] 330914 0
The primary outcome is the ability of augmented reality to guide PCNL puncture. This is measured as a binary positive or negative success in achieving renal access while utilising the technology. This data will be collected directly at time of surgery from the operative note.
Timepoint [1] 330914 0
At time of surgery.
Secondary outcome [1] 408063 0
Number of puncture attempts required to achieve renal access, expressed as a positive integer. This will be collected directly from the procedure note.
Timepoint [1] 408063 0
At time of surgery.
Secondary outcome [2] 408314 0
Qualitative ease of operation
Timepoint [2] 408314 0
Post-operative survey (to be completed immediately post operation by the attending surgeon). This survey will be developed by the research team specifically for this study.
Secondary outcome [3] 408315 0
Speed of access, measured in seconds. This will be measured directly at the time of surgery by the research team.
Timepoint [3] 408315 0
To be measured at time of surgery.
