Utilization of the Bosniak classification system requires, first, previous identification of the cystic nature of a renal mass as defined earlier (refer to Sect. 2.1) with the exception of very small lesions (<5–10 mm) and, second, examination of the cystic lesion if it belongs to the field of application of the Bosniak classification system.

Magnetic resonance (MR) and contrast-enhanced ultrasonography (CEUS) imaging may demonstrate findings that are not depicted at CT, and there may not always be a clear correlation between the findings at MR and CEUS imaging and those at CT. The Bosniak classification was originally developed to classify renal cysts based on CT findings, but MRI and CEUS can also be used [12,[22][23] [24] as the latter techniques show even higher The Bosniak renal cyst classification has, thus far, passed the test of time and has been a useful method for diagnosing and suggesting the management of complicated cysts and cystic neoplasms. In the past 25 years, there have been continuous advances in the diagnosis of disease throughout the body owing to the introduction of new technology The Bosniak classification is a diagnostic tool for the differentiation of cystic changes in the kidney. The process of categorizing renal cysts may be challenging, involving a series of decisions that may affect the final diagnosis and clinical outcome such as surgical management. The Bosniak classification system is not intended to be used alone to guide the management of patients with complex renal cysts. Management of complex renal cystic lesions is dependent on the individual patient’s combination of imaging findings, clinical factors, and available treatment options [ 16 ]. According to the classification, cystic renal lesions can be divided into subtypes with a low risk of malignancy (Bosniak I-II, nearly 0%) and subtypes with elevated rates of malignancy: Bosniak IIF (“F” = follow-up), Bosniak III, and Bosniak IV with a risk of malignancy of approximately 5%, 50%, and 100%, respectively [5,6,7].

Durch die Entwicklung neuer Kontrastmittel (KM) kommt der kontrastmittelverstärkte Ultraschall (CEUS) in der Evaluation von Nierenzysten vermehrt zum Einsatz. Studien haben eine gute Vergleichbarkeit der CEUS mit der Bosniak-Klassifikation in der CT gezeigt. Historic points In 1983, using early computed tomography (CT) scan technology, renal cysts were discovered in 33% of patients in the same age group. The Bosniak renal cyst classification system was initially reported in 1986, using CT scan findings. the Bosniak classification has been widely adopted and accepted because it addresses a difficult clinical problem and is easy to apply by both 2017-06-01 · The Bosniak classification system (BCS) for cystic renal lesions was developed based on CT findings .

The Bosniak classification is widely used by radiologists and urologists for addressing the clinical problem assessing renal cysts 3. It was last updated in 2005 12.. A Bosniak classification, version 2019 11 has been proposed to increase the accuracy and include MRI features but does not yet (c.

2021) have widespread validation. The Bosniak classification of cystic renal masses (version 2019), or usually simply Bosniak classification, version 2019, is a proposed update of the classic/current Bosniak criteria.The update hopes to improve on the classification's predictive power for malignancy and minimize the number of benign lesions undergoing treatment. Bosniak Classification of Renal Cystic Disease. The Bosniak classification was described in 1986.

Additionally to normal native B-mode sonography, several new methods are in clinical use to improve diagnostic accuracy of unclear cases. Bosniak I: eindeutig benigne Zyste. Kein Malignitätsrisiko.

Sie haben keine Trennwände, zeichnen sich jedoch durch eine klare Visualisierung mit Ultraschall, The classification system by M.A. Bosniak has simplified radiologists to classify renal lesions and help assess the likelihood of underlying benignity and malignancy by means of CT criteria since its introduction in 1986 [ 4] (Figure 1).
