Each mass was categorized according to the Bosniak classification and CT was chosen as gold standard. Kappa was calculated for diagnostic accuracy and data was compared with pathological results. The Bosniak classification system utilizes specific CT or MR imaging features to help classify cystic renal lesions into those that are likely benign (and do not require surgical resection) from those that are likely malignant (and thus require surgical resection). From February 2011 to June 2012, 46 complex renal cysts were prospectively evaluated by three readers. Each mass was categorized according to the Bosniak classification and CT was chosen as gold standard. Kappa was calculated for diagnostic accuracy and data was compared with pathological results.

It was not until the patient deteriorated further that an Using Bosniak-classification 64/87 renal cysts (73.6%) were rated equal compared to CT with upgrade of four lesions (4.6%) and downgrade of 19 lesions (21.8%) by CT (Intra-class-correlation [ICC A careful helical CT abdomen focusing on the kidneys with intravenous contrast was obtained from all patients. The lesions were categorized into surgical and medical renal cystic masses using the Bosniak classification system supported by histology reports and follow up protocols for medical cases. The Bosniak classification was initially developed solely on the basis of CT findings [1, 2]. Subsequently, a few studies have suggested that MR [ 31 , 40 ] and CEUS [ 4 , 8 , 41 – 46 ] may be equally useful for characterisation of complex renal cystic masses. Bosniak 신장 낭종 분류 체계(Bosniak renal cyst classification system)는 이러한 병변의 진단과 관리를 돕기 위해 만들어졌습니다. 조영 전후 CT의 형태학적 및 조영 증강 양상에 따라 낭종성 신장 종괴가 5 가지 범주 중 하나로 분류됩니다(표 1) 2019-01-19 · ESOU 2019 renal cancer session on the treatment of cystic renal masses, the classification and role of cross-sectional imaging, three kinds of renal masses: solid, cystic, and mixed; renal cell carcinomas (RCCs), CT Bosniak classification of renal cysts, classify renal cysts according to the risk of malignancy. In 1986 Morton Bosniak published a review article in which he suggested a classification and further management of cystic lesions of the kidneys based on findings on contrast-enhanced computed tomography (CT) (1).

Currently the standard of care in evaluating a complex renal cyst is using a contrast-enhanced computed tomography (CT)  Bosniak classification of renal cysts, Case courtesy of Dr Matt Skalski, Exempel på vad som registreras är preoperativ utredning med CT av  Både ultraljud och MRT tenderar att ge något högre Bosniak-klassificering än DT Bosniak classification of renal cysts, Case courtesy of Dr Matt Skalski,  Percutaneous CT guided microwave ablation of 105 T1a-T1b renal tumors: technique efficacy The TNM classification system (19) is used to classify and stage RCC (3, 6).

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. 1. To understand which features of a renal cyst to assess during CEUS in order to assign a Bosniak classification, especially to distinguish between benign and malignant lesion. 2.

B. Class II cyst with few hairline thin septa (arrows). C. Class IIF cystic mass with minimal smooth thickened septa and calcification (arrow). Bosniak classification of renal cystic masses has five cathegories. It was devised by Dr. Morton A. Bosniak to separate lesions that require surgery (Bosniak III and IV) from those that can be safely followed-up or left alone.

CT surveillance showed increased cyst size in the left kidney with cystic changes, however, the Bosniak classification remained the same.

Ct bosniak classification

Two independent reviewers extracted data on malignancy rates in Bosniak THE ORIGINAL BOSNIAK CLASSIFICATION OF RENAL CYSTS In 1986, Bosniak [8] proposed a classification of renal cysts. The diagnosis and management of complex renal cysts was contentious, and a combination of CT, US and urography was being used to distinguish between benign and malignant lesions. Bosniak described the US The Bosniak classification for CT and MRI has been recently revised. 3 A Bosniak classification for CEUS has not been developed.
