Abstract:
This study investigated the correlation between results of the pelvic organ prolapse quantification (POPQ) system at 3 days and at 2 months postpartum with obstetric parameters and lower urinary tract symptoms (LUTS) in 125 primiparae with vaginal delivery. The clinical characteristics, prevalence of pregnancy-related LUTS, and POPQ scores were evaluated. Regarding the relationship of obstetric parameters with POPQ scoring, the gh was found positively correlated with the body mass index and vaginal laceration at 2 months postpartum. The POPQ evaluation did not find the LUTS to be significantly related to the prolapse score. The mean scores of points C and D were significantly increased, and gh, pb, and tvl were significantly decreased between the initial and 2-month follow-up scores. Our results revealed that a decrease in vaginal size is the principal change during the first 2 months postpartum and that with the exception of gh, neither the obstetric parameters nor the LUTS were associated with the POPQ scoring system.
