Objective To evaluate the safety and efficacy of ex vivo ureteroscopy (ExURS) as means of rendering a donated kidney stone-free in a living related renal transplantation.Methods Clinical data were analysed of ExURS as means of rendering a donated kidney stone-free in a living related renal transplantation and relative literature was reviewed.The ECT results showed that GFR of left and right kidney was 38.7 and 42.3 ml/min respectively.The donor underwent a left laparoscopic donor nephrectomy.Immediately after cold perfusion,ExURS was performed with 4 ℃ ice-cold saline irrigation.Basket extraction and holmium laser lithotripsy was performed.Calculi were fragmented with pneumatic intracorporeal lithotripsy and fragments were removed with forceps.F6 indwelling ureteral stents were kept during transplantation.Urine flowed out immediately after reperfusion of the allograft and the distal ureter appeared edema 2 min later.Routine ureter-bladder wall anti-reflux replantation was done after the resection of the edema part.Results Pyeloscopy was successfully performed.A total of 2 calculi,diameter 8,12 mm,were visualized in donor kidney.The ex vivo treatment time was 30 nin.The warm and cold ischenia time was 60s and 50 min,respectively.There were no intraoperative complications.At a follow-up at 8 months,there was no recurrent calculi formation in the recipient and donor.Conclusion ExURS is technically feasible to render a stone-bearing kidney stone free without compromising ureteral integrity or renal allograft function.
