“…No significant differences were found in terms of SFR and the rate of complications (4). The insertion success rate can vary depending on the caliber of UAS, as demonstrated by Li et al (5) They found that the utilization of 10/12 Fr UAS resulted in a higher insertion success rate (91.2% vs. 86.9%, P = 0.006) and lower severity of ureteral wall injury (80.1% vs. 85.2%, P < 0.001) compared to 12/14 Fr UAS. The SFR was similar in both groups.…”
