[Current trends in the method used for urine derivation after radical cystectomy for muscle-invasive bladder cancer].

Bladder cancer ranks 7th in the world among all malignant tumors in men and 11th in both sexes. Radical cystectomy is the gold standard of muscle-invasive bladder cancer treatment in most countries of the world. A large number of fundamentally different options for urine derivation is developed.

[The incidence of malignant transformation of renal cysts of category 1, 2, and 2F by the BOSNIAK classification into multilocular cystic renal cell carcinoma].

Relevance: Renal cysts remain the most common of benign renal lesions, but current literature is lacking large observational studies on the incidence of their malignant transformation.

Aim: To assess the incidence of malignant transformation of renal cysts of category 1, 2, and 2F by the Bosniak classification into multilocular cystic renal cell carcinoma.

Materials And Methods: From January 2009 to December 2017, 177 patients with renal cysts of category 1 (n=50), 2 (n=74), and 2F (n=53) underwent laparoscopic decortication.
