METHOD OF URINE DERIVATION AFTER RADICAL CYSTECTOMY Russian patent published in 2011 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to urologic oncology and can be used for urine derivation after radical cystectomy. For this purpose after ablation of urinary bladder sigmoid colon is transected on the border of middle and lower thirds with sewing distal end of cut off part of colon tightly. Interintestinal anastomosis "end-to-side" is formed by means of circular suturing device. After that implantation of ureters into formed urine reservoir is performed through separate micro-cuts on the line of mesentery attachment. At the same time, additionally edges of ureters are sewn through cut in sigmoid colon on the line of their intersection with colon mucosa with further muff-like "covering" sigmoid colon with mesentery along 2.5-3 cm zone of ureter-sigmoid-anastomoses and distal ends of ureters, preliminarily intubated with uretral stents. After that, urine reservoir cut is sutured and fixed to anterior abdominal wall, through which ureteral stents are passed outside.

EFFECT: method makes it possible to reduce risk of post-operation complications development: anastomoses failure, attacks of acute pyelonephritis, ureter stricture and reduce operation time.
