title: Prevalence of hydronephrosis in patients with genital prolapse.
abstract: OBJECTIVE
  To determine the prevalence of hydronephrosis in patients with genital prolapse and evaluate contributing factors.
  
  
  METHODS
  Retrospective study of the records of 189 patients with pelvic organ prolapse who underwent preoperative renal imaging studies.
  
  
  RESULTS
  Of the 189 patients 31 (17.4%) had hydronephrosis; in 20 (10.6%) patients the hydronephrosis was mild, in 7 (3.7%) it was moderate and in 4 (2.7%) it was severe. The patients with hydronephrosis were older (mean age 68+/-9.5 SD vs. 60.5+/-10.8 SD, P<0.001) had a higher creatinine levels (0.84+/-0.4 SD vs. 0.78+/-0.3 SD P<0.005) and had a higher degree of uterine prolapse (mean 2.6+/-0.9 SD vs. 1.1+/-1.2 SD, P<0.005). After adjusting for age and type of prolapse, only patients with uterine prolapse remained significantly more likely to suffer from hydronephrosis (adjusted odds ratio 1.9, 95% CI 1.1, 3.2).
  
  
  CONCLUSIONS
  The prevalence of hydronephrosis in patients with genital prolapse is appreciable and is related primarily to degree of uterine prolapse.
