“…Researchers have mentioned the significance of UAS in improving drainage and decreasing intrarenal pressure during ex vivo percutaneous nephroscopy, 25 and as well facilitate removal of stone fragments during ESWL. 26 During our study we found that the use of UAS efficiently facilitated irrigant drainage and maintained low intrarenal pressure (5-10mmHg) throughout the procedure even with high-pressure irrigation using a peristaltic pump. The improved irrigation flow rendered good visualization and facilitated rapid removal of stone fragments through the access sheath.…”

“…Treatment outcomes for SWL can be variable and secondary to multiple factors. Residual fragments have been shown to persist or grow in as many as 60% of patients and become symptomatic or require intervention in as many as 71% [10]. The 2004 AUA Staghorn Guideline Update reports an overall success rate for SWL of 54% with partial staghorn calculi cleared at a rate of 60% and complete staghorn only at a rate of 42%.…”

We present our experience with the use of the ureteral access sheath for the management of small impacted lower third ureteral stones, in comparison with more standard techniques. Ninety-eight consecutive patients, aged 18-73 years (mean 48.5), with small (diameter < or = 10 mm) impacted lower third ureteral stones (< 5 mm in 56, and 5-10 mm in 42 patients) were randomly managed with either a 12/14F coaxial ureteral dilator/sheath and a 7.5F flexible ureteroscope (group A; 48 patients), or with balloon dilatation and the 7.5F flexible ureteroscope (group B; 50 patients). In both groups, stones were grasped and extracted with a basket, and when necessary they were disintegrated with a 1.9F electrohydraulic lithotripsy (EHL) probe. Postoperatively, excretory urography was performed at 1 month and patients were followed-up for 1 year. The mean operative time was 45.5 min in group A, and 58.5 min in group B (P<0.05). EHL was performed in 16 (33.3%) patients of group A, and in 12 (24%) patients of group B. In group B, balloon dilatation was performed in 28 (56%) patients. Ureteral perforation was revealed in 4 (8%) patients of group B. The follow-up imaging tests showed stone-free status in 46 (95.8%) patients of group A and in all (100%) patients of group B. No long-term complications were recorded. Endoscopic management of small impacted lower third ureteral stones with the ureteral access sheath is a quicker and safer procedure, in comparison with the more standard approach, bearing comparable efficacy.
