title: [Impact of genital prolapse on the upper urinary tract].
abstract: The authors reviewed five cases of genital prolapse affecting the upper urinary tract and causing renal failure.
  
  
  METHODS
  Five patients aged 55 to 75 years presented with genital prolapse, which was known by the patient in 3 cases for a period of 2 to 30 year, but left untreated. All cases had induced bilateral dilatation of the uretero-pyelocaliceal cavities with severe obstructive renal failure in 3 cases, moderate renal failure in 2 cases and associated with hypertension in 2 cases. Repair of prolapse, preceded by upper urinary tract diversion by ureteric and bladder catheters in 3 cases or pessary + bladder catheter because of the patient's age in 2 cases, cured or improved renal failure in 4 patients; only one patient had to be treated by dialysis because of the severity of the residual renal failure severity.
  
  
  CONCLUSIONS
  The frequency (4%) of aetiopathogenic mechanisms (ureteric compression, progressive stretching of the ureter and posterior tilting of the trigone) are analysed. The delayed onset of sudden deterioration and the varying degrees of severity of renal failure demand emergency treatment of stage III prolapse with primary diversion of the upper urinary tract, currently by double J stents, until correction or improvement of renal function, after which surgical repair of the prolapse can be performed according to the usual surgical rules. Intravenous urography is still indicated in this situation. Palliative treatment is only indicated in elderly patients or patients with a high operative risk. The best treatment remains prevention by detection and treatment of prolapse before the development of this fortunately rare complication.
  
  
  CONCLUSIONS
  This short clinical series emphasizes that undiagnosed prolapse can still be complicated by repercussions on the upper urinary tract with a risk of renal failure.
