Wilms’ tumour The most common paediatric renal malignancy, Wilms’ tumour usually presents before the age of 3 years. Although the lesion generally occurs in previously fit individuals, there are several known predisposing conditions, including hemihypertrophy, Beckwith–Wiedemann syndrome and sporadic aniridia, with a 30–40% incidence in sporadic aniridia. The tumours are large at presentation, presenting with […]

Vesicoureteric reflux Vesicoureteric reflux, the retrograde passage of urine from the bladder up the ureter and into the kidney, predisposes the child to urinary tract infection and the development of reflux nephropathy. In the first year of life only, reflux is more common in boys than in girls and is usually more severe. Conversely, after […]

Vascular abnormalities of the spleen Splenic infarct Splenic infarction is most commonly associated with endocarditis, sickle cell disease and myeloproliferative disorders and also with lymphoma and cancers. It usually results from thrombosis of one or more of the splenic artery branches. Because the spleen is supplied by both the splenic and gastric arteries, infarction tends […]

The use of Doppler ultrasound is an integral part of the examination and should not be considered as a separate entity. Many pathological processes in the abdomen affect the haemodynamics of relevant organs and the judicial use of Doppler is an essential part of the diagnostic procedure. Colour Doppler is used to assess the patency […]

RENAL TRACT INFLAMMATION AND INFECTION The most common urinary tract infections are bacterial in origin, with viral and fungal infections being comparatively rare. The diagnosis is made by urinalysis after the patient presents with symptoms of dysuria, haematuria and/or suprapubic or renal angle pain. The origin of the infection may be via the blood stream […]

Upper abdominal ultrasound scanning technique is not something that can be learnt from a book. There is absolutely no substitute for regular practical experience under the supervision of a qualified ultrasound practitioner. There are, however, some general approaches which help to get the best from the scanning procedure: ● Scan in a systematic way to ensure […]

ULTRASOUND-GUIDED DRAINAGE Many fluid collections are the result of surgical intervention and often cannot be differentiated on ultrasound alone. Diagnostic aspiration of fluid collections is used to establish their exact nature: this may include haematoma, lymphocoele, urinoma, biloma, pseudocysts and others. Postoperative haematomas are normally treated conservatively and tend to resolve spontaneously. Insertion of a […]

Ultrasound guided biopsy methods – Blind biopsy With this method a position on the skin surface is marked overlying the organ or lesion to be biopsied, using ultrasound to localize. This remains acceptable for diffuse disease, when only a representative sample of liver tissue is required. Nevertheless, it is good practice even in these situations […]

Complications of ultrasound-guided biopsy Postprocedure complications such as haematoma requiring blood transfusion and trauma to adjacent viscera occur very infrequently when ultrasound guidance is used. As expected, the risk of complications is less in fine-needle biopsy than with larger needles; however, there is no significant difference in complication rate between a standard 18G Tru- Cut […]

ULTRASOUND-GUIDED BIOPSY: Percutaneous biopsy of organs, masses or focal visceral lesions is an integral part of the diagnostic process for a large number of patients. Although changes on ultrasound may confirm the suspected clinical suspicion, that is, a bright liver may indicate fatty change, a nodular liver may suggest cirrhosis or enlarged kidneys of increased […]
