Incidental renal stones in potential live kidney donors: prevalence, assessment and donation, including role ofex vivoureteroscopy

摘要: What's known on the subject? and What does study add? Previously, donors with asymptomatic stones found incidentally CT were not considered ideal donor candidates because of presumed risk morbidity to both recipient. Increasingly, studies show that these risks are low. This aims evaluate long-term safety using ex vivo ureteroscopy remove from kidney bench before donation. Outcomes so far suggest this technique can safely render a stone-free transplantation. This has led 20 more transplants in our institution than would otherwise be possible. Objectives To prevalence renal potential population. To assess success (ExURS) explanted kidneys transplantation. Patients Methods We conducted retrospective analysis 377 computed tomography (CT) angiograms between October 2004 May 2007 population. Between 2005 2011, suitable underwent ExURS. Stones removed basket extraction or fragmented holmium laser transplantation. Immediate complications transplanted recipients recorded. Donors followed yearly ultrasonography remaining addition standard follow-up protocol. Results Review showed 5% stones. Out 55 (19 identified further 36 since 2007), proceeded donation, stone size ranging 2 12 mm. Of patients, 17 10 patients; five retrieval, four fragmentation one retrieval. There no early late allograft stone-related evidence imaging at mean (range) (1–24) months. There been reported recurrence any date eight >1-year (mean 26 months, range 12–49 months). Conclusions Asymptomatic present donors. ExURS used transplantation, without subjecting an additional stone-removing procedure. Continued is still required ensure approach.
