ABSTRACT
【Objective】 To investigate the safety and efficacy of flexible vacuum aspiration ureteral access sheath in ureteroscopic lithotripsy in the treatment of renal and upper ureteral calculi. 【Methods】 Clinical data of 41 cases treated in our hospital were retrospectively analyzed, including 20 cases treated with flexible vacuum aspiration ureteral access sheath (experimental group), and 21 cases treated with traditional ureteral access sheath (control group). The stone-clearance rate, operation time, postoperative fever (T>37.5 ℃), length of hospital stay and hospitalization costs were compared between the two groups. 【Results】 All operations were successful. The experimental group had significantly shorter operation time than the control group [(54.0±19.8) min vs. (76.6±20.1) min, P0.05). 【Conclusion】 Flexible vacuum aspiration ureteral access sheath in flexible ureteroscopic lithotripsy can shorten the operation time, improve stone-clearance rate and reduce incidence of postoperative fever, which is worth promoting.
ABSTRACT
Renal subcapsular abscess(RSA) is a rare disease with unknown etiology and pathogenesis. CT is an important assistant examination for the diagnosis. In this study, we reported 2 cases of RSA. One case achieved good therapeutic effect by timely debridement and surgery drainage, and the other case refused to perform debridement and drainage, which lead to the death. This kind of disease develops quickly and progresses rapidly. The adequate debridement and surgery drainage are important in treating this disease.
