{"title":"Impact of Adding Urethral Sonography with Retrograde Urethrography in Preoperative Assessment of Anterior Urethral Stricture.","authors":"Nidhi Sehgal, Vinod Priyadarshi","doi":"10.4103/jmu.jmu_4_23","DOIUrl":"10.4103/jmu.jmu_4_23","url":null,"abstract":"<p><strong>Background: </strong>Even with underlying risk factors and limitations, retrograde urethrography (RGU) is the most popular imaging modality in the assessment of anterior urethral stricture. Urethral sonography (SUG) is an able imaging modality in use for the last few years which evaluates anterior urethral stricture without these risks, though it is still not much popular due to its complexity.

Seventeen clinical patients with various age-related soft-tissue changes were subjected to ultrasound assessments, targeting issues such as soft-tissue sagging, supra- and subplatysmal adipose tissue excess, platysma thickness, and localization of ptotic platysma strands. The ultrasound examinations successfully identified specific anatomical features contributing to age-related soft-tissue changes in all 17 patients. This information guided tailored treatment plans, resulting in remarkable esthetic improvements in each case. The discussion emphasizes ultrasound's invaluable role as a diagnostic tool for precisely identifying soft-tissue alterations in the lower face and neck. The noninvasive nature and high spatial resolution of ultrasound make it particularly effective for this purpose. The corrective methods guided by ultrasound findings proved to be minimally invasive and yielded successful outcomes in all cases, promoting high levels of patient satisfaction. The study highlights the underutilization of ultrasound's diagnostic potential in clinical practice and highlights the importance of its incorporation into routine assessments. Ultrasound emerges as a cost-effective, noninvasive, and accessible means of accurately diagnosing age-related soft-tissue changes, empowering clinicians to tailor rejuvenation procedures to each patient's unique needs. The hope is that by emphasizing its utility, this study encourages the broader adoption of ultrasound in clinical practice.</p>","PeriodicalId":45466,"journal":{"name":"Journal of Medical Ultrasound","volume":"32 3","pages":"244-248"},"PeriodicalIF":0.9,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11414957/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142298167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is interest in predicting preeclampsia (PE) early in pregnancy to reduce PE and its subsequent complications. There is no cheap and easily available, reliable predictor for PE. Some studies have shown that the lateral location of placenta is associated with adverse pregnancy outcomes due to PE. The lateral placenta is yet to be proven as a strong predictor of PE to initiate preventive measures. Placental localization can be easily done on routine ultrasonography during pregnancy. In the light of these observations, a prospective study was done to study any association between PE and placental location by ultrasound in third trimester. Research Question: Is there any association between placental location on ultrasound and preeclampsia in third trimester? The objective is to study association between location of placenta and preeclampsia and compare placental location in normotensive pregnancies with that in PE in third trimester.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A prospective comparative, case-control, observational study was conducted in the Department of Obstetrics and Gynecology at North DMC Medical College and Hindu Rao Hospital, Delhi, India, from August 2019 to April 2020. The study population included 200 pregnant women with singleton pregnancy in third trimester, without any medical disorders such as diabetes mellitus, hypertension, renal disease, cardiac disease, and coagulation disorder or smoking. One hundred women had preeclampsia and 100 were normotensive controls. Ultrasound was done after filling F form as per the Government of India guidelines to rule out sex determination, and placenta was localized by ultrasound. Placenta was classified as central when it was equally distributed between the right and left sides of the uterus irrespective of anterior, posterior, or fundal position and lateral when 75% or more of the placental mass was on one side of the midline. Placental location was compared in hypertensive and normotensive pregnancies.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Out of the total 200 women, 152 (76%) had central and 48 (24%) had lateral placenta. Ninety-two percent of controls and 60% of cases had central placenta. Forty percent of cases and only 8% normotensive women had lateral placenta. Lateral placenta was five times more frequent in presence of PE as compared to normotensive controls. Out of 152 women with central placenta, 92 (60.5%) women were normotensive but with lateral placenta, only 8 (16.7%) had normal blood pressure. PE was present in 83% of women with lateral placenta and in only 39.47% with central placenta. This difference was statistically significant as &lt;i&gt;P&lt;/i&gt; &lt; 0.0001 as per Chi-square test.
