title: [Ureteric reconstruction with reconfigured ileal segments according to Yang-Monti. A 4-year prospective report].
abstract: BACKGROUND
  We report on 4 years experience with ileal ureteric replacement using the Yang-Monti procedure.
  
  
  METHODS
  From April 2001 to January 2009 reconfigured ileal segments were used for total (in 16) or partial (in 2) substitution of the ureter in 18 patients (mean age 47.4 years) with functional ureteric loss secondary to radiogenic or iatrogenic conditions. An antireflux implantation into the native bladder was done in 16 patients. All patients were followed prospectively according to a standardized protocol.
  
  
  RESULTS
  The mean follow-up was 4.2 years (0.5-8 years). There were no perioperative deaths. Ultrasound controls showed an improvement of the upper tract dilatation in 11, a constant finding in 5 and a worsening in 2 cases. All of the treated renal units had evidence of improved renal function in ten and stabilization in eight patients. Neither a metabolic complication nor mucous obstruction was observed. Minor short-term complications, mainly febrile urinary tract infection and paralytic ileus, occurred in 50% and long-term complications, infections and hernia in 22%.
  
  
  CONCLUSIONS
  The ileal ureteral substitute with reconfigured segments offers distinct advantages. A short bowel segment is used with the consequent absence of metabolic complications and excessive mucous production. It allows construction of an ileal ureter with a suitable cross-sectional diameter without any need for tailoring and makes it possible to use an antireflux technique. The intermediate results are encouraging.
