[Acucise endoureterotomy for distal ureteral stenosis in a renal transplant patient].

The treatment of ureteric strictures in renal transplantation used to be surgical, but has recently benefited from progress in endourology. The authors report the case of a renal transplant recipient who developed late stricture of the ureterovesical reimplantation of the transplant. After percutaneous nephrostomy, which restored good renal function, retrograde endoureterotomy was performed using an Acucise ureterotome balloon, followed by ureteric modelling on a 7F double J stent for 2 months. With a follow-up of 18 months, renal function was normal and ultrasonography showed residual hypotonia of the transplant cavities and no vesicorenal reflux was detected by retrograde voiding cystourethrography. Acucise retrograde endoureterotomy can constitute a simple endourological treatment for late ureteric strictures in renal transplantation.
