Diagnostic accuracy of transvaginal ultrasonography and hysterosalpingography in the detection of uterine cavity pathologies among infertile women.

Background: Uterine cavity pathology may affect the endometrium or myometrium, resulting in distortion of the uterine cavity, and is responsible for 2%-5% of infertility. The methods for its assessment usually involve imaging modalities like pelvic ultrasonography, often transvaginal-(TVS), and hysterosalpingography-(HSG), with hysteroscopy-(HSC) as the gold standard. However, HSC is not readily available in resource-poor-settings. Purpose: To determine and compare the diagnostic accuracy of TVS and HSG in detecting uterine cavity pathology using HSC as a gold standard. Materials and Methods: A cross-sectional analytical study of consenting infertile women for evaluation of the uterine cavity using transvaginal-ultrasonography, hysterosalpingogram, and hysteroscopy. The primary-outcome-measures were the sensitivity, specificity, and accuracy of TVS and HSG in detecting uterine cavity abnormalities using HSG as the gold standard. Results: Eighty-eight participants were analysed for this study. The lesions confirmed on HSC were intrauterine-adhesions (43.1%), endometrial polyps (14.8%), submucous fibroids (18.2%), intrauterine-septum (13.6%), and cavity distortion (14.8%). The overall sensitivity with TVS was 57.7%, with a specificity of 97.6%, a positive-predictive-value (PPV) of 88.2%, and a negative-predictive-value (NPV) of 88.2%, giving a percentage-accuracy of 88.2%. In comparison, HSG had a sensitivity of 72.1%, a specificity of 99.4%, a PPV of 97.4%, and an NPV of 92.0%, giving an overall accuracy of 92.9%. The detection rates of TVS and HSG in this category were: fibroids (97.7% vs 89.8%; p = .0004) and adhesions (73.9% vs 87.5%; p = .0002), respectively. Conclusion: HSG appears to be the superior modality for detection of obliterative uterine cavity pathologies, while TVS is better suited for myometrium and endometrial lesions.

Comparison of urine protein-creatinine ratio and urine dipstick test for significant proteinuria in preeclamptic women.

Background: Assessing for significant proteinuria in pregnancy (SPIP) stands as a key indicator for diagnosing preeclampsia. However, the initial method typically employed for this assessment, the urine dipstick test, often yields inaccurate results. While a 24-h urine collection is considered the most reliable test, its implementation can lead to delays in diagnosis, potentially affecting both maternal and fetal well-being. The urine protein-creatinine (P/Cr) ratio can be used as an alternative to 24-h urine protein analysis, but its diagnostic accuracy has remained uncertain. There is a need to compare the diagnostic accuracy of urine P/Cr ratio and dipstick urinalysis for SPIP, especially in resource-poor settings. Objectives: To determine and compare the diagnostic accuracy of urine P/Cr ratio and dipstick urinalysis in a spot urine specimen for the diagnosis of SPIP among women evaluated for preeclampsia using 24-h urine protein excretions as a gold standard. Design: This is a comparative cross-sectional study. Methods: The study involved 82 singleton pregnant women evaluated for preeclampsia from 20 weeks of gestation who underwent dipstick and P/Cr ratio tests in the same urine sample. Women at risk of preeclampsia were given a specimen container for the collection of urine samples on an outpatient basis. Participants were trained and told to collect the urine sample 24 h prior to their next antenatal appointment. However, those on admission and evaluated for preeclampsia had their 24-h urine collected in the hospital. The outcome measures included sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio and accuracy for the two tests. Significant proteinuria was defined as a P/Cr ratio >0.27 or ⩾2+ of proteinuria on the dipstick test. Preeclampsia was confirmed in women with both high blood pressure and SPIP. Results: The mean age of participants was 28.65 ± 5.76 years. Comparatively, the diagnostic accuracy (91.46% (95% CI = 83.29-96.59) vs 59.76% (95% CI = 48.34-70.44), p = 0.001), sensitivity (94.74% vs 70.00%, p = 0.021), specificity (84.00% vs 43.75%, p = 0.001), negative predictive value (87.50% vs 48.28%, p = 0.003) and positive predictive value (93.10% vs 66.04%, p = 0.001), respectively, were higher for the spot urine P/Cr ratio than dipstick test. In addition, the positive likelihood ratio and the negative likelihood ratio for spot urine P/Cr ratio versus dipstick test were (1.93 vs 1.24) and (0.07 vs 0.69), respectively. Conclusion: The spot urine P/Cr has superior diagnostic accuracy in the determination of significant proteinuria in pregnant women being evaluated for preeclampsia than the widely used dipstick test. A more robust multicenter study is needed to compare the diagnostic accuracy of spot urine PCR with the standard 24-h urine protein in low-income settings.

Comparison of diagnostic tests for the detection of protein in the urine of pregnant women with preeclampsia • Preclampsia is one of the medical disorders that can complicate pregnancy, and it is a major cause of feto-maternal morbidity and mortality during pregnancy. • Preeclampsia is the development of elevated blood pressure beyond the normal value during the second half of pregnancy with a significant amount of protein in the urine. • The detection of a significant amount of protein in the urine is one of the criteria for the diagnosis of preeclampsia; however, there are limitations with the various methods of urine protein detection and estimation. • The study was conducted among women being evaluated for preeclampsia. We compared the diagnostic accuracy of the urine protein-creatinine ratio and dipstick urine test for the diagnosis of significant proteinuria in pregnancy using 24-hour urine protein excretions as a gold standard. • Our findings showed that the spot urine protein-creatinine ratio has superior diagnostic accuracy when compared to the regular dipstick urine tests for the detection of significant protein in the urine among pregnant women being evaluated for preeclampsia.

Post-cesarean vesicouterine fistula (Youssef syndrome): report of two cases.

Vesicouterine fistula (VUF) is a rare complication of cesarean section. We present two cases of VUF that were successfully managed by transperitoneal surgical repair. The first case presented with the Youssef classical triad: cyclical hematuria (menouria), amenorrhea and urinary continence, while the second case presented with total urinary incontinence with normal menstruation. In both cases, diagnosis was confirmed by hysterogram and both were managed by transperitoneal surgical repair. The clinical features, etiologic factors, diagnostic procedures and treatment modalities are discussed in relation to the case and others as reported in the literature.
