METHOD FOR REMOVAL OF BLADDER CANCER EN BLOC USING "CIFERBLAT-6" TECHNIQUE Russian patent published in 2025 - IPC A61B10/04 A61B18/20 A61B1/307 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to urology. Zone is marked with 1-3 mm incisions of the mucosal and submucosal layers of the bladder, first according to the clock of the conditional clock-face: at 3, 6, 9 and 12 o’clock, then at 4, 7, 10, 1 o’clock. Marking is carried out at a distance of not less than 5 mm from the tumour edge. Mucosal and submucosal layers are dissected at 6 o’clock from an expected circular incision line at 1 mm short of the tumour edge. Further, the layer is dissected at the interface of the superficial and deep layers of the detrusor in region of 10 to 2 o’clock, the “thin” fibres of the superficial muscular layer and the “thick” fibres of the deep muscular layer are dissected; all circular incisions are combined into one circular line – at 5, 8, 11 and 2 o'clock. Layer is incised on the interface of the deep and superficial muscular layers of the detrusor muscle within 6, 9 and 3 o’clock with the dissection covering the full depth of the dissected portion within 6 o’clock. Tumour is excised from the circular incision in a projection of the centre of the tumour base with the resection initially performed within 6 o’clock to a projection of the tumour. Then in zone 9 o’clock, then in zone 3 o’clock. Tissues are alternately mechanically tensioned by a laseroscope beak and the stretched tissues – “connecting fibres” are cut. Resection is completed within semicircle from 10 to 2 o’clock. Resected tumour and base block is removed completely; a plasma ablation of the resection crater and resection edges is performed. During the resection and after the residual tumour with the base has been dissected away, coagulation of the bladder wall blood vessels is performed with a bipolar loop.

EFFECT: method provides the uniform indent along the whole circular edge of the resection, maximum reliability of the morphological conclusion.
