In his study, Dr. Chalouhy and his team recruited patients who were considered at a higher risk for undergoing general or spinal anesthesia who were undergoing percutaneous flexible ureteroscopy as an alternative to standard RIRS or PCNL. Rather than perform these more standard procedures on these patients, Dr. Chalouhy introduced a 10Fr renal access catheter under local anesthesia using fluoroscopic and ultrasound guidance. The goal of his study was to determine whether this ultra-mini-perc surgical approach through a 10Fr access sheath under local anesthesia was a safe and efficient means of attenuating stone burdens.
The results demonstrated that, for their small patient cohort, that ultra-mini-perc, when compared to standard PCNL and mini-perc procedures, translated to similar operative times and a lower stone-free rate of around 77%. Because of the already high-risk patient cohort that were deemed suitable for the ultra-mini-perc procedure due to their high risk for undergoing general anesthesia, the average hospital stay for these patients was prolonged up to 11 days.
