title: Significance of urodynamic assessment of lower urinary tract in dialysis patients before renal transplantation.
abstract: BACKGROUND
  Some dialyzed patients suffer from lower urinary tract (LUT) anatomic and functional disturbances. Complete LUT assessment should be performed to decide whether they can be included on the waiting list, because such disorders, if not diagnosed and properly treated before transplant, may lead to graft loss.
  
  
  METHODS
  Based on data in the medical records of 4170 dialysis patients, 535 were selected for further investigation: 265 patients after undergoing urethrocystography or urethrocystoscopy, were included on the waiting list for transplantation and 145 patients underwent nephroureterectomy owing to reflux, nephrolithiasis, polycystic renal disease, or hydronephrosis. Five patients with urethral or bladder neck stricture underwent urethral dilation or bladder neck incision. These patients were also ultimately listed for transplantation. Twenty-two patients, with serious LUT disease were qualified for kidney transplantation after extra-anatomic urine outflow. Ninety-eight patients underwent a urodynamic study (URD) to assess LUT disturbances.
  
  
  RESULTS
  Of 535 studied patients, 460 (86%), including those who underwent surgical or pharmacologic treatment, were ultimately listed for kidney transplantation. Out of 98 patients who underwent a URD, 45 (46%) were included for kidney transplantation, and 47 for transplantation with atypical urinary outflow. Six patients were excluded from transplantation owing to refusal of investigations or serious contraindications.
  
  
  CONCLUSIONS
  All potential kidney recipients should undergo proper evaluation of the LUT before being qualified for kidney transplantation. This study allows selection of patients who should undergo surgical and/or pharmacologic treatment before transplantation.
