Dr. Doizi chose 9 commonly debated points in support or opposition of UAS and presented the best available data on each. Areas that he believed to be controversial or inconclusive based on conflicting literature included the effect of UAS on facilitation of multiple entries /re-entries, operating time, cooling effect on renal tissue, ureter protection, stone-free rates, and cost. However, he reported that the ability of UAS to maintain lower intrarenal pressures (thanks to improved outflow) and decrease risk of infectious complication are consistently supported by solid data. These findings are summarized in the image below.
Dr. Doizi’s presentation of the data for the use of UAS indicates that, while some aspects of this practice are likely beneficial, there is a clear need for more investigation of other variables, as most of the data remain too weak to form consensuses.
