title: Nondismembered ureteroplasty for congenital midureteral stenosis: a new application of an old technique.
abstract: OBJECTIVE
  To share our experience with nondismembered ureteroplasty (NDU), a novel application of an old technique in congenital midureteral stenosis (CMS).
  
  
  METHODS
  A 35-year-old man was diagnosed as a case of CMS, a rare benign condition on the basis of extensive evaluation, including ultrasonography, intravenous urography, ethylenedicystine renal scan, antegrade and retrograde contrast study of the left kidney and ureter, and a 64-slice computed tomographic angiography of the abdomen with 3-dimensional reconstruction. He was managed by open NDU, where a longitudinal incision over the narrowed segment was closed transversely using the Heineke-Mikulicz principle, thereby preserving the midureteral blood supply, which is considered tenuous.
  
  
  RESULTS
  The patient had a successful outcome and is asymptomatic at 1-year follow-up, with significant resolution of hydroureteronephrosis on ultrasonography, and a nonobstructed left kidney with 37% differential renal function on renal scan.
  
  
  CONCLUSIONS
  Nondismembered ureteroplasty is a meticulous surgical technique emphasizing blood supply preservation; it can be a useful option in relatively long-segment CMS and adds another method in the surgeon's armamentarium for repairing this rare condition. This technique can be especially useful during laparoscopic or robotic repair of such stenosis.
