Objective: To expand the diagnostic armamentarium for medullary sponge kidney (MSK), we evaluate the use of high-resolution multidetector computed tomography (MDCT) for MSK diagnosis and compare to the standard intravenous urography (IVU). Despite a significant prevalence amongst stone formers, diagnosis of this well described condition has declined. IVU, the gold standard in MSK diagnosis, has largely been replaced by CT, which has previously been shown unable to demonstrate signs of MSK...

BACKGROUND: Congenital hydronephrosis is often caused by aberrant renal vessel and it is difficult to be diagnosed and treated at the early stage due to lack of the significant symptoms. Although current medical diagnosis tools are widely used, the aberrant renal vessel cannot be displayed very well in the images. OBJECTIVE: To investigate whether applying computed tomography (CT) angiography with 3D reconstruction can improve efficacy in diagnose of this congenital hydronephrosis...

Introduction: Genito Urinary Tuberculosis (GUTB) is a widespread disease seen in urology practice. The true incidence and prevalence of GUTB is difficult to estimate because a large number of patients remain asymptomatic. Aim: To recognize typical and atypical clinical and radiological features of tuberculosis and to emphasize the need for diagnosing GUTB early. Materials and Methods: This was a retrospective study conducted in 110 cases of GUTB diagnosed and treated in two teaching institutions over a period of three years, from July 2002 to June 2005...

The objective of this study is to evaluate the average radiation exposure in children with renal stones before SWL treatment. Mean radiation exposure values were evaluated in 110 children before SWL treatment. While some children referred to the emergency department (ED) with colic pain, remaining cases referred to outpatient department (OD). Although low-dose NCCT was performed in ED; KUB and abdominal sonography were first performed in other cases referring to OD where CT has been applied if needed. The type of imaging modality used and the mean radiation exposure were evaluated and comparatively evaluated with respect to the department referred, patient as well as stone related parameters...

The National Synchrotron Light Source (NSLS) ceased operation in September 2014 and was succeeded by NSLS-II. There were four in-vacuum undulators (IVUs) in operation at NSLS. The most recently constructed IVU for NSLS was the mini-gap undulator (MGU-X25, to be renamed IVU18 for NSLS-II), which was constructed in 2006. This device was selected to be reused for the New York Structural Biology Consortium Microdiffraction beamline at NSLS-II. At the time of construction, IVU18 was a state-of-the-art undulator designed to be operated as a cryogenic permanent-magnet undulator...

AIMS: Ultrasound is a noninvasive method used for the diagnosis of urinary lithiasis. When the length of the stone is less than 5 mm, its detection may be difficult. The twinkling artifact (TwA) is an intense alternating color signal behind calcifications and stones in different organs. The aim of this paper was to evaluate the importance of the TwA in detecting kidney stones less than 5 mm in length. MATERIAL AND METHODS: We examined 230 patients with lumbar pain or a history of kidney stones...

Scrotales fistulas are rare and often represent secondary lesions of tuberculosis. Mucinous adenocarcinomas are tumors containing at least 50% of extracellular mucus. They occur most commonly in the rectosigmoid; scrotal location is rare. We report the case of a 54-year old patient, with no particular past medical history, with secondary mucinous adenocarcinoma of the scrotum revealed by scrotal fistulas. The patient had suffered from recurrent scrotal fistulas for two years, with no other associated signs...

Urogenital tuberculosis (UGTB) is the most common form of extrapulmonary TB and is responsible for a destructive inflammation of the renal parenchyma and urinary tract often leading to the loss of kidney function. For these reasons, the early diagnosis of this disease, once considered disappeared in developed countries, is very important to establish a prompt and efficient treatment. However, the subtle and non-specific symptoms, often represented by recurrent and persistent lower urinary tract symptoms, can confound and delay the diagnosis...

Wilms' tumour originates predominantly in the renal tissue; in rare cases it can also arise from extra-renal sites accounting for 0.5-1% of cases of Wilms' tumours seen. A diagnosis of extra-renal Wilms' cannot be easily established with clinical and radiological features except when the histological facts are provided. Wilms' tumours arising from extra-renal sites may not be different in clinical features, protocol of treatment and outcome from a typical intra renal Wilms' tumour. A 2-year-old boy presented with an asymptomatic abdominal swelling for 3 months...
