BACKGROUND Renal squamous cell carcinoma is a rare neoplasm with poor prognosis. Chronic irritation from nephrolithiasis and/or pyelonephritis is the leading cause. CASE PRESENTATION We described a 51-year-old male patient who was admitted because of left flank pain. Ultrasonography showed a renal cyst containing calculus. However, contrast-enhanced ultrasonography and CT scan revealed an irr...

Complete anuria is an uncommon clinical presentation that is usually due to an obstructive (postrenal) cause. Less frequent aetiologies include catastrophic vascular compromise (prerenal), massive rhabdomyolysis or antiglomerular basement membrane disease (intrinsic renal). Two-dimensional ultrasonography is the initial imaging investigation of choice in these patients, as it is non-invasive, c...

We present a case of renal stone associated with bilateral pelvic diverticula. The initial diagnosis by ultrasonography and plain abdomen radiography (KUB) was urolithiasis with a 15-mm calculus in the right renal pelvis. The patient was referred for extracorporeal shock wave lithotripsy, but no stone fragments were yielded. So, further evaluations were performed by using repeated ultrasonograp...

Renal colic is a common reason for presentation to emergency departments, and imaging has become fundamental for the diagnosis and clinical management of this condition. Ultrasonography and particularly noncontrast computed tomography have good diagnostic performance in diagnosing renal colic. Radiologic management will depend on the tools available at the center and on the characteristics of t...

urinary tract infection (uti) may lead to irreversible changes in renal parenchyma. early diagnosis using scintigraphy with technetium-99 m -labeled dimercaptosuccinic acid (dmsa) scan and early treatment may decrease or prevent development of renal parenchymal lesions. the aim of this study was to assess the occurrence of renal parenchymal lesion in children admitted with a first-time symptoma...

• Renal angiomyolipomas (AMLs) are usually easy to diagnose with imaging alone. They have unique characteristics on ultrasonography, computerised tomography and magnetic resonance imaging that usually allow AMLs to be differentiated from other renal masses. • If this is not possible on imaging criteria then biopsy can be performed and AMLs have unique immunohistochemical staining that allows th...

the common use of maternal ultrasonography has increased the apparent incidence of neonatal hydronephrosis. many of these cases are found to have partial obstruction at the ureteropelvic junction (upj). these patients are safely managed in our institution with careful observation and only occasionally require surgical intervention. the authors present two contrasting cases of suspected upj obst...

The clinical effects of routinely imaging the renal tract (by intravenous urography and ultrasonography) were evaluated prospectively in 128 consecutive patients with prostatism. Patients with haematuria, previous renal disease, or infection were excluded. Urologists completed a standard questionnaire in the patient's notes stating the diagnosis and the intended management. The patient then had...
