19 Apr 2018 Approximately 1 in every 3 adults over the age of 50 has a renal cyst, (simple versus complex), malignant potential (Bosniak classification),

Laparoscopic resection of right renal cyst (the size is 10 cm) (Bosniak 3) Professor Puchkov K.V. is performing an operation (2017). In this film the technique of

6, 7 Category 2F lesions were created later as a group to be followed to prove cyst benignity. 8, 9 However, in the era of active surveillance for small renal masses differentiating a surgical lesion from one that can be monitored has become increasingly important. 10, 11 In our study, one-half of small (< 4 cm) Bosniak category 3 and 4 cystic renal lesions were downgraded, and most (88%) of the small Bosniak category 2F lesions were downgraded or remained stable on follow-up. In none of the patients with lesions that were Bosniak category 3 or 4 at follow-up imaging did recurrent or metastatic disease develop.

No patient in this study developed metastatic disease within the three-year followup period. The Bosniak classification system of renal cystic masses divides renal cystic masses into five categories based on imaging characteristics on contrast-enhanced CT. It is helpful in predicting a risk of malignancy and suggesting either follow up or treatment. As a result, many Bosniak III masses are benign but treated (18, 19), resulting in unneeded procedural morbidity, decreased renal function, and excess health care costs (49 – 53). Bosniak category III cystic renal lesions are indeterminate in malignant potential and most commonly managed with surgical excision. While the malignancy risk of Bosniak III cystic lesions is thought to be approximately 50% (2), reported malignancy rates range from 31% (3) to 100% (4). The renal cyst masses in some cases, especially category II to III lesions, may be over evaluated by the Bosniak criteria based on MR findings.

While the malignancy risk of Bosniak III cystic lesions is thought to be approximately 50% (2), reported malignancy rates range from 31% (3) to 100% (4). The renal cyst masses in some cases, especially category II to III lesions, may be over evaluated by the Bosniak criteria based on MR findings. It is necessary to combine MR features with CT findings in evaluation and management of these cases with renal cystic masses.

La classification de Bosniak établie en 1986 et révisée en 1993 (Tableau I) [2, 3], a pour objectif de classer selon des critères morphologiques, les kystes atypiques en fonction de leur risque évolutif. Ainsi la classification de Bosniak établie 5 stades différents en fonction de l'aspect tomodensitométrique du kyste.

7,8 In benign Bosniak 2 or 3 lesions there is no enhancement within the cyst or the cyst wall. A renal cyst is a fluid collection in or on the kidney. There are several types based on the Bosniak classification.

Diagnosis of Bosniak category 3 lesions as malignant or benign may require surgical resection or percutaneous biopsy on CT or MRI characterization.

Introduction Complex indeterminate renal cystic masses (Bosniak type III) can have benign and malignant causes and have been traditionally considered as

In this film the technique of 13 Mar 2020 Table 2: Bosniak Renal Cyst Classification (Open Table in a new window) Minimally complex cyst; diameter ≤3 cm; uniform hyperattenuation. Kidney robot surgical procedure to put off bosniak cyst, has. 2 solutions (query 2 ou 3 levels parallélisme système de bosniak.

nefropati NOS och njursjukdomar NOS med morfologiska lesioner, specificerade i Njurcyster är enkla (I Bosniak) och komplexa (II, IIF, III och IV Bosniak).

Smaller (<4 cm) Bosniak III cysts were more likely to be malignant and lesion size should be taken into consideration when considering management of complex cysts. 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.
