METHOD OF URETER TRANSPLANTATION Russian patent published in 2011 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to urology, and is intended for surgical treatment of violation of urine passage in ureter as result of obstructive process, or insufficiency of vesicourethral fistula, as well as in case of kidney transplantation. Tunnel is formed. Ureter is placed into said tunnel. Distal part of ureter is fixed to urinary bladder. Preliminarily, on mid-line in suprapubic part performed is trocar puncture cystostomy under ultrasound control and introduction into urinary bladder cavity of drainage tube-intubator with perforation on spiral on its distal end. Operation access to ureter is performed more laterally than usual suprapubic access in inguinal region. Ureter is cut off from urinary bladder, perforated part of tube is removed out of formed in it orifice. Tunnel between layers of urinary bladder walls is formed. Ureter is dissected at acute angle, preferably 45 degrees, tube is introduced in it for 2/3 of its length. Narrowed ureter is passed through intubated with tube tunnel. Ureter is fixed to urinary bladder wall. Transplantation is performed with apex of cut toward urethra, ureter mucosa is sewn near base of acute cut with two sutures. The remaining part of ureter cut is placed into urinary bladder lumen, fixed in stretched position like petals in three different directions by means of "П"-shaped "anchor" sutures, applied from urinary bladder lumen outward, through all layers of urinary bladder walls with further drawing of ureter inside urinary bladder.

EFFECT: method makes it possible to reduce length of operation access, reduce its trauma, as rectus muscles of abdomen are not cut off, white line, where post-operational hernias are formed, is not dissected, urinary bladder wall is not opened and access to its lumen is provided on small section, blood circulation and innervation of urinary bladder are not disturbed.
