Introduction. The choice of method of urine derivation is main question after removal of the urinary bladder.

Materials and methods. The choice of the method of urine derivation is based on the indications and contraindications to a particular method, the patient's wishes, his somatic status and individual anatomical features, as well as kidney function. Bricker procedure is the most used form of incontinent urine derivation. 10% of patients after the formation of Bricker ileumconduitis have complications from anastomoses, most often-left ileo-ureteral anastomosis. Li Y. et al. modified the standard procedure for the formation of ileal conduit in order to minimize complications associated with left ileo-ureteral anastomosis.

Description of a clinical case. The article presents a clinical case of using Li-Kotb modification technique of ileal conduit.

Discussion. Due to the presence of a single functioning left kidney in the patient, we sought to provide reliable urine derivation. Therefore, we leaned towards a modified method of forming of ileal conduit using Li-Kotb method, rather than the classical technique.

Conclusion. According to the authors of the method, the modified Bricker ileal conduit formation technique is safe, reproducible and reduces the risk of failure and stricture of the left ileo-ureteral anastomosis.
