Evaluation of Bosniak Type IIF and III Renal Cysts with Contrastenhanced Ultrasound Renal cysts were classified by Bosniak, and this classification was modified in New modalities for evaluation and surveillance of complex renal c
Purpose: We sought to better characterize the frequency of Bosniak cyst class changes, identify predictors of change and progression, determine the average growth rate of cysts and validate the safety of active surveillance. Materials and Methods: Consecutive patients referred for the management of complex cysts (Bosniak 2F or greater) were included in analysis. All imaging studies were Se hela listan på journals.lww.com Bij een Bosniak III-cyste is er in ongeveer de helft van de gevallen sprake van een maligniteit. Het betreft dan meestal cysteuze niercelcarcinomen, die klinisch milder verlopen dan solide tumoren. In onze ogen zijn er goede argumenten om bij Bosniak III-cysten < 4 cm surveillance toe te passen, net zoals tot nu toe gebruikelijk is bij Bosniak IIF. Bosniak 2F; Kyste dont l'aspect, s'il n'est pas franchement suspect, ne permet pas de rassurer complètement. Le F signifie Follow-Up (Surveillance en anglais).

Although there have been long-term surveillance studies of Bosniak category 2F lesions , to our knowledge ours is the largest single-institution study of active surveillance of confirmed (by Objective: The purpose of this study was to determine the percentage of small (< 4 cm) Bosniak category 2F, 3, and 4 lesions that regress during active surveillance. The growth rate of 3n and 2F cysts was 0.19 and 0.11 cm per year (p = 0.0493 and 0.0327, respectively). Locally advanced or metastatic disease did not develop in any patient. Conclusions: A diagnostic change in Bosniak 3s and 2F cysts is common and Bosniak 3n cysts behave more like Bosniak 4 cysts. type 2F: (the “F” is for follow-up needed) cysts are more complex that simple type II cysts, but do not meet the criteria for a type III classification. These cysts may demonstrate an increased number of septa or minimal smooth thickening of the wall or septa.
Bosniak III cysts the risk for malignancy is approximately 50 %. If malignant, histology usually shows cystic renal cell carcinoma which has been reported to follow a more favourable course compared to solid tumours. In our opin-ion there are good arguments to imply surveillance for Bosniak III cysts < 4 cm, similar to the approach of IIF le-sions.
No examples of metastatic progression of a Bosniak 2F lesion on surveillance has been reported in the literature. The Dutch and UK guidelines for living kidney
Therefore, small size should be a consideration for conservative management. Bosniak 2F renal cystic lesions feature morphologic characteristics between Bosniak I and III categories, the majority of which remain benign. However, a minor part of Bosniak 2F lesions may progress to malignancy. The purpose of this study was to assess Bosniak 2F cystic lesions during follow-up examinations by CEUS.
Blue curves indicate Bosniak 2f. Surveillance renal US did not detect a stage change and in 1 case it ultimately delayed the diagnosis of a true Bosniak 3 cyst, which was 2F on US. In 3 cases of Bosniak 2F cysts the septations became more nodular and the cysts progressed to 3n.
Our institution (NYU Langone Health) has a longstanding active surveillance program for these patients that has allowed long-term study. cm) Bosniak category 2F, 3, and 4 lesions that regress during active surveillance. MATERIALS AND METHODS. In this retrospective study, a hospital database was searched from January 1, 2005, through September 9, 2017, for small (< 4 cm) Bosniak cate-gory 2F, 3, and 4 lesions studied with initial and follow-up unenhanced and contrast-enhanced Bosniak was the normal radiological assessment procedure for cystic renal lesions.
For patients with small solid or Bosniak 3/4 complex cystic renal masses, especially those <2cm, AS is an option for initial management. Surveillance of small renal lesions.

RESULTS: 121 patients (84:37 M:F) were identified with 136 renal lesions (84, 37 and 15 Bosniak category 2F, 3 and 4) and followed for 1-12.3 years (mean 3.5 years). 87% (73/84) of 2F lesions were downgraded or remained stable.

Resection of the Bosniak 2F cyst provides 2 advantages: the recipient receives a new donor kidney and will be free of dialysis, and the donor will be free of surveillance. Conclusions: We present a practical guideline for kidney donors with Bosniak 2F cysts,

We searched for retrospective evidence of Bosniak IIF renal cysts, cystic renal lesions, Bosniak IIF lesions, Carcinomas, Renal Cell, and Malignant Neoplasms obtainable up to April 2019. We selected articles published in English.
Consecutive patients referred for management of complex cysts (>= Bosniak 2F) were included. Microsimulation model of CT versus MRI surveillance of Bosniak IIF renal cystic lesions: should effects of radiation exposure affect selection of imaging strategy?

87% (73/84) of 2F lesions were downgraded or remained stable. 48% (25/52) of 3/4 lesions were downgraded. Bosniak 2F tipo di cisti renali è una categoria del sistema di classificazione bosniaco delle masse cistiche renali. Il sistema di classificazione inserisce le cisti renali (renali) in cinque categorie, a seconda dei risultati sulla TC. Oltre a Bosniak 2F, gli altri quattro includono: Bosniak 1, Bosniak 2, Bosniak 3 e Bosniak 4.
