FIELD: medicine.
SUBSTANCE: invention relates to field of medicine, namely to urology, can be used in surgical treatment of ureter pelvic part constriction in patients with ablated or non-functioning opposite kidney. Medial laparotomy is performed. Health ureter of opposite ablated kidney is mobilised. After that frontward of main vessels retroperitoneal tunnel is formed. Through tunnel ureter is passed on the side of narrowed ureter, where lower kidney pole, pelvis and ureter proximal part are exposed within the limits of healthy tissues. Crossed uretero-ureteroanastomosis "end-to end" is formed.
EFFECT: method allows to preserve anatomo-functional state of ureterovesical segment, including ureter orifice, which will eliminate probability of its narrowing or vesicouretral reflux, as well as to create anastomosis which is functionally reliable and available for adequate drainage with stent or intubator.
