title: [Utilize the simplified POP-Q system in the clinical practice of staging for pelvic organ prolapse: comparative analysis with standard POP-Q system].
abstract: OBJECTIVE
  To determine the association between simplified pelvic organ prolapse quantification system(S-POP-Q)and the standard pelvic organ prolapse quantification system(POP-Q)in describing pelvic organ prolapse.
  
  
  METHODS
  This was an observational study. From Jan. 2010 to Jan. 2014, 256 subjects with pelvic floor disorder symptoms underwent two exams: a POP-Q exam and a S-POP-Q exam. For the S-POP-Q system, vaginal segments of the exam were defined using points Ba, Bp, C, and D. For the POP-Q system vaginal segments of the exam were defined using points Aa, Ba, Ap, Bp, C, and D. The inter-system consistency between the overall ordinal stages, the anterior vaginal wall stages, the posterior vaginal wall stages, the cervix stages, the posterior fornix or vaginal cuff stages from each two kind of exam were compared.
  
  
  RESULTS
  The Kendall tau-b correlation coefficient for overall stage was 0.81, the Kendall tau-b correlation coefficients were 0.81, 0.81, 0.85, 0.88 for the anterior vaginal wall, for the posterior vaginal wall, for the cervix, for the posterior fornix or vaginal cuff, respectively.
  
  
  CONCLUSIONS
  There is almost perfect association between S-POP-Q and POP-Q in describing pelvic organ prolapse.
