Many patients presenting with haematuria undergo intravenous urography, renal tract ultrasound and cystoscopy. Renal tract ultrasound includes imaging of the bladder, which can significantly increase scan times by necessitating bladder filling, which can impact negatively on appointment scheduling. Little published literature exists on whether ultrasound of the bladder in the presence of haematuria is of any clinical benefit. This study aims to redress this by comparing bladder ultrasound to the gold standard of cystoscopy and also by assessing temporal implications in this patient group. A prospective study was undertaken where 96 consecutive urology-referred patients had their bladder ultrasound findings compared with the findings of cystoscopy under the headings of mass, trabeculation, diverticulum, stone and fistula. Ultrasound had poor sensitivity (47.8%), but good specificity (94.5%) in detecting the predefined bladder pathologies with a poor Kappa score of 0.33 when compared with cystoscopy. In addition, there was a significant time burden placed on the list by including bladder scanning as part of the renal tract sonographic assessment. In conclusion, bladder ultrasound is not shown to be a clinically useful adjunct to cystoscopy for the detection of bladder pathology. We would recommend that, in the setting of haematuria, ultrasound be used only for upper tract assessment.

ABSTRACTObjective and designOur prospective study is one of the largest prospective study assessing the role of detailed lung ultrasound features to discriminate the etiological diagnosis of Community acquired pneumonia (CAP) in children.MethodologyWe prospectively analysed patients aged from 1 month to 17 years admitted between March 2018 and April 2020 who were hospitalized for CAP. For all patients included in the study, history, clinical parameters, microbiological data, and lung ultrasound data were collected.Patients were stratified into three main groups (“bacterial”, “viral”, “atypical”) according to the presumed microbial aetiology and lung ultrasound findings evaluated according to the aetiological group.ResultsWe found that some ultrasound findings as size, number and distribution of consolidations, the position and motion of air bronchograms, pleural effusions and distribution of vertical artifacts significantly differ (p < 0.05) in children with bacterial, viral and atypical CAP. Conversely, clinical parameters and laboratory were not able to significantly distinguish between these groups. Chest x-ray, despite being still widely used, was the less useful tool in this discrimination.ConclusionOur study provides a detailed analysis of LUS features able to predict the etiology CAP in children. These findings may help the physicians to better manage a child with CAP and to offer personalized approach, from diagnosis to treatment and follow-up.
