For this comparison, Dr. Brooks and team retrospectively reviewed 247 patients who received ureteroscopy for nephrolithiasis from 2010 to 2016. Of these patient, only 79 had stent removal at either 3 or 7 days. These 2 groups of patients were analyzed and compared in terms of demographic information, pre-operative variables, and post-operative outcomes.
Following analysis, Dr. Brooks found that 39% of 3-day patient group experienced post-procedure related events (Emergency department visit, hospital call, and clinic visit) compared to 21% in the 7-day patient group. Additionally, the 3-day patient group was significantly more likely to have a post-procedure related event than 7-day patient group and there was a trend towards more frequently reported flank pain in 3-day patient group as well. There was no difference seen between the 3-day and 7day patient groups in clinically insignificant stone fragments, post-operative hydronephrosis, or hospital readmissions.
Dr. Brooks concluded that leaving a stent for 3-days versus 7-days does not result in improved outcomes and may instead lead to worse outcomes with regard to post-operative events and flank pain. This was especially seen in the 3 day patient group following stent removal.
