A 20-year-old woman presented to our outpatient clinic with a 5-week history of recurrent right lumbar back pain. Contrast-enhanced computed tomography scan showed a Bosniak class IV renal cyst. She was treated with radical nephrectomy. Histopathology revealed xanthogranulomatous pyelonephritis.

The aim of this anthropometric survey, conducted between 2015 and 2016 in Bosnia and Herzegovina (BiH), was to map local geographical differences in male stature and some other anthropometric characteristics (sitting height, arm span). In addition, to investigate the main environmental factors influencing physical growth, the documented values of height would be compared with available nutritional and socioeconomic statistics. Anthropometric data were collected in 3192 boys aged approximately 18.3 years (17-20 years), from 97 schools in 37 towns...

A primipara at term was admitted to the labour ward with spontaneously emerged severe abdominal pain in the right flank and kidney. The patient was not known with any obstetric or urologic conditions. An acute caesarian section was performed due to the pain and pathological results of the cardiotocography, and a healthy child was delivered. During surgery, a haematoma was detected in the retroperitoneal space. A computed tomography (CT) of abdomen showed a Bosniak type IV tumour with surrounding haematoma in the kidney...

PURPOSE: We systematically evaluated the Bosniak classification system with malignancy rates of each Bosniak category, and assessed the effectiveness related to surgical treatment and oncologic outcome based on recurrence and/or metastasis. MATERIALS AND METHODS: In a systematic review (according to PRISMA [Preferred Reporting Items for Systematic Reviews and Meta-Analyses] statement and the QUADAS-2 [Quality Assessment of Diagnostic Accuracy Studies] criteria) we selected 39 publications for inclusion in this analysis and categorized them into 1) surgical cohorts-all cysts treated surgically and 2) radiological cohorts-cysts with surgical treatment or radiological followup...

Cystic renal masses are a common entity with a wide differential diagnosis encountered by the radiologist in daily practice. Their characterization relies on the Bosniak classification system that has been widely accepted by radiologists and urologists as a pertinent diagnostic and communication tool. It has been designed to separate cystic lesions requiring surgery (categories III and IV) from those that can be ignored and left alone (categories I and II) or followed (category IIF). Utilization of the Bosniak classification requires, first, previous identification of the cystic nature of a renal mass with the exception of very small lesions...

Aim: To describe the presentation and management of a urinoma developing as a complication of laparoscopic cryoablation of a Bosniak III renal cyst. Case: A 74-year-old woman presented with acute onset of severe left lower abdominal pain 1 day after a laparoscopic cryoablation of a 3 cm multilobular left cystic renal mass. CT revealed a perinephric fluid collection adjacent to the lower pole of the left kidney with active urinary extravasation seen on retrograde pyelogram, confirming the presence of an urinoma...

INTRODUCTION: We aimed to introduce the diagnostic value of diffusion-weighted (DWI) magnetic resonance imaging (MRI) for distinguishing benign and malignant renal cystic masses. METHODS: Abdominal DWI-MRIs of patients with Bosniak categories 2F, 3, and 4 cystic renal masses were evaluated retrospectively. Cystic masses were assigned as benign or malignant according to histopathological or followup MRI findings and compared with apparent diffusion coefficient (ADC) values...

OBJECTIVES: To compare the diagnostic performance of computed tomography, magnetic resonance imaging and contrast enhanced ultrasonography for the assessment of complex renal cysts. METHODS: We carried out a prospective single-center study from January 2012 to December 2013. We included patients with Bosniak category 2F or 3 renal cysts found on computed tomography and reviewed by two expert radiologists. Magnetic resonance imaging and contrast-enhanced ultrasonography were then carried out...

AIM: To investigate the role of contrast enhanced ultrasound (CEUS) in evaluating patients with renal function impairment (RFI) showing: (1) acute renal failure (ARF) of suspicious vascular origin; or (2) suspicious renal lesions. METHODS: We retrospectively evaluated patients addressed to CEUS over an eight years period to rule-out vascular causes of ARF (first group of 50 subjects) or assess previously found suspicious renal lesions (second group of 41 subjects with acute or chronic RFI)...

Recent advances in pediatric urinary tract imaging include development of alternative imaging methods without use of ionizing radiation; evolving understanding of the relationship of urinary tract infection, vesicoureteral reflux, and renal scarring, including the important role of dysfunctional voiding; development of a consensus nomenclature and risk-based classification for fetal and antenatal urinary tract dilation; advances in the understanding of sporadic and inherited renal cystic disease; and a proposed modification of the Bosniak criteria for distinguishing complex renal cysts from cystic renal tumors in children...

Ultrasound is a common and established imaging method for the initial characterization of renal lesions. The widespread used Bosniak classification (I-IV) classifies renal lesions in five individual groups using contrast-enhanced computer tomography (CE-CT), magnetic resonance imaging (MRI) and/or contrast-enhanced ultrasound (CEUS) imaging criteria. For complex pathologies, CEUS/MRI image fusion is a novel imaging technique for the differentiation of benign and malignant renal lesions. Compared to CE-CT and MRI alone, ultrasound image fusion offers the additional possibility of being a real-time imaging technique that can be used together with other cross-sectional imaging techniques...

A 35-question survey investigating elements of a CT or MRI report describing a renal mass was created through an iterative process by the Society of Abdominal Radiology Disease-Focused Panel on renal cell carcinoma. Surveys were distributed to consenting abdominal radiologists and urologists at nine academic institutions...

BACKGROUND: Renal cell carcinoma (RCC) represents the most common malignant epithelial neoplasm of the kidney. Accurate assessment of the renal masses, defining the histologic subtype and the grade of differentiation of the tumor, is vital to ensure an adequate case management as well as for staging and prognosis. Recently, diffusion-weighted imaging (DWI) magnetic resonance imaging (MRI) tends to be increasingly appealing for the clinicians as an imaging procedure of choice for the diagnosis and staging of the RCC, which is predetermined by several advantages over CT...

INTRODUCTION: Around 10 % of renal cell carcinomas (RCC) are cystic, while some benign cysts have complex appearance in conventional diagnostic tests such as computed tomography (CT) or magnetic resonance imaging (MRI). These renal complex cystic masses (RCCMs) are a challenging entity in urological practice and sometimes have a difficult management, requiring surgical removal. Contrast-enhanced ultrasound (CEUS) is a very sensitive test detecting microvascularization in real time, and it has been used in the diagnostic workup of these kinds of lesions...

OBJECTIVE: To evaluate the performance of contrastenhanced ultrasound (CEUS) in the risk stratification of indeterminate renal lesions picked up incidentally on abdominal imaging, in patients with renal impairment. METHODS: A retrospective study was performed of nonconsecutive patients who underwent CEUS at our tertiary care centre for indeterminate renal lesions between March 2010 and September 2014. A total of 63 patients with 74 nodules were assessed with CEUS and stratified into either benign (Bosniak I, II, IIF) or suspicious for malignancy (Bosniak III, IV or hypervascular solid lesions)...

Cystic renal masses are a specific renal entity with a different management from solid lesions. Renal cysts are present in over 50% of patients after 50 years. Radiological diagnostic enables to rank their suspect nature of malignancy through the Bosniak classification. Type III and IV lesions are at high risk of malignancy, and are usually treated by partial nephrectomy.
