METHOD FOR TREATING LARGE, GIANT AND MULTILOCULAR RENAL CYSTS Russian patent published in 2007 - IPC A61B17/94 

FIELD: medicine, urology.

SUBSTANCE: one should form a percutaneous puncture canal and widen it with the help of bougies. Through the canal it is necessary to introduce a nephroscope into cystic cavity and evacuate cystic content at subsequent application of a drainage tube. Moreover, on evacuating the cystic content the nephroscope should be withdrawn into retroperitoneal space. Into area of a fallen cyst one should introduce carbon dioxide up to 14-16 mm mercury column by, thus, creating "a working space" to introduce there a trocar through incision along median axillary line for manipulators. Then comes mobilization and dissection of cystic walls due to applying an electrocoagulator at 0.5 cm against renal parenchyma. The innovation enables to completely evacuate the content of large, giant, multilocular renal cysts endoscopically, without open operation and general anesthesia that provides radical healing of the disease mentioned and excludes its relapse.

EFFECT: higher efficiency of therapy.
