Abstract
Objectives: The aim of this study was to evaluate the correlation of postvoid residual (PVR) measurement in pelvic organ prolapse patients by transabdominal sonography (TAS) and urinary catheterization. Materials and Methods: During November 2021-March 2022, a cross-sectional study was conducted in newly diagnosed as pelvic organ prolapse (POP) patients stage 1-4 patients at Female Pelvic Medicine and Reconstructive Surgery (FPMRS) clinic, King Chulalongkorn Memorial hospital, Thailand. The PVR was determined by TAS and urinary catheterization. TAS was independently performed by two investigators. Each investigator performed ultrasound twice. After completed ultrasound evaluation, urinary catheterization was immediately performed. Results: Seventy-seven POP patients were included. The mean ± standard deviation of age was 70.65 ± 9.15 years. Fifty-one percent of patients had advanced stage of prolapse. The correlation coefficients (r) of TAS and catheterization by 2 evaluators were 0.74 (p < 0.001) and 0.79 (p < 0.001). The intra-rater reliability of PVR measurement by TAS of both evaluators were 0.93 and 0.95. The inter-rater reliability of PVR measurement by TAS were 0.78 (1<sup>st</sup> measurement) and 0.79 (2<sup>nd</sup> measurement). Conclusion: There was a high positive correlation of the PVR assessment by TAS and PVR assessment by urinary catheterization in POP patients. This technique can be used as the alternative choice for PVR measurement in patients with POP.
