URINARY TRACTS DRAINAGE Russian patent published in 2007 - IPC A61M27/00 A61B17/11 A61F2/82 A61F2/88 

FIELD: urology.

SUBSTANCE: drainage can be used for draining different (pyeloureteral, uretero-ureteral and uretero-vesical) anastomosis as well as anamostosis at urine derivation after cystectomy into continuous abdominal tube, suspending uro-ostomy, and orthopedic intestinal conduct. Urinary tracts drainage is made of elastic biological inert polymer material; it has diameter of 5-10 Ch and it can be installed by means of conductor. Drainage is made in form of spiral with length of 7-10 cm and with pitch of 5-7 turns per 1 cm; spiral is made of inert elastic organic polymer thread with diameter of 0,2-0,4 mm. Spiral turns on to non-spiral part made of same material to have length of 40 cm. Bigger relation of diameter-length and absence of continuous wall provide adequate drainage which helps to prevent atony of ureter and reduces chance of periureteritis due to limiting contact between drainage and ureter and due to higher elasticity of drainage.

EFFECT: improved efficiency oft treatment.
