Scope of project: There has been an increase in the incidence of kidney stones together with rising obesity rates in developed (America, Europe, Japan) and developing countries (India and China). Several studies have shown that morbidly obese individuals excrete more oxalate in their urine, predisposing them to kidney stones. The minimally invasive procedure of percutaneous access to the kidney (PAK) establishes a keyhole-size entrance to remove kidney stones. Percutaneous nephrolithotomy (PCNL) is currently one of the most complicated stone surgery techniques to master. The task of obtaining access manually by the surgeon requires substantial skill. Inaccurate placement of the needle can risk injuring the kidney and adjacent organs, compromising the procedure, as well as the clinical outcome of the patient. The team has developed a smart robotic-guided system to help surgeons speed up the process of accurately aligning the needle to the stone target embedded in the kidney. The device relieves the surgeon of the need to select an approach because it provides a robotic means to guide and stabilise the alignment of the needle with automated real-time correction to reach the target accurately. The purpose of the system is to shorten the training period, increase the accuracy, and reduce the risk of the surgery, thereby enabling more surgeons to perform PAK procedures.
Status: The robotic-guided system is in the final stage of clinical trial and will be available in Mar 2019.
