Abstract

Ultrasound scanning (USS) and high vaginal swab culture and urine microscopy culture and sensitivity (m/c/s) tests are the most common investigations used for the diagnosis of pelvic inflammatory disease (PID) in our locality. The aim of this study was to determine the diagnostic accuracy of ultrasound in the diagnosis of PID keeping laboratory high vaginal swab/urine microscopy, culture as gold standard. The USS, high vaginal swab and urine m/c/s reports of patients referred with PID conditions between January 2010 to April 2013 were obtained from the medical records departments of Nnamdi Azikiwe University teaching hospital, Nnewi, Anambra state. The diagnostic accuracy was determined by calculating sensitivity, specificity, positive predictive value and negative predictive value using performance characteristics test. Descriptive and inferential statistics were also used. Spearman rho’s non parametric analysis and statistical package for social sciences (SPSS) version 17.0 was equally used. The total number of subjects that were scanned for PID was 120. The highest number of subjects 80 (66.6%) was seen in 21 to 30 years age group. The sensitivity, specificity, accuracy, negative predictive value and positive predictive value of ultrasound in PID diagnosis was found to be 100, 65.3, 89.2, 100 and 86.3%, respectively. There was no significant correlation between USS diagnosis of PID and HVS/urine culture findings (p > 0.01). Ultrasound is valuable as the first line of investigation (screening tool) in the diagnosis of PID and should be used in conjunction with other medical investigations to facilitate accurate diagnosis of PID.
