Full-text articles published in peer-reviewed journals dedicated to the results of onlay ureteroplasty using various materials, as well as monographs on surgical treatment of long ureteral strictures are presented in the article. Over the past decade, onlay technique for the treatment of long ureteral strictures using flaps or grafts on a vascular pedicle have been introduced. Experimental data on the results of onlay ureteroplasty using autologous vein or bladder mucosa, as well as the small intestine submucosa (SIS) have been published in the literature. Due to the availability and good survival rate, buccal and tongue mucosal flaps are widely recognized as the optimal graft for onlay ureteroplasty. There are also studies on the results of ureteroplasty using SIS or appendix graft onlay for the upper and middle ureteral strictures. A use of tissue-engineered flaps for ureteroplasty remains contradictory. Further research in this direction may allow to obtain optimal grafts for onlay ureteroplasty. However, oral mucosa or appendix are predominant materials, which are used for onlay ureteroplasty.

D013524	Surgical Flaps	Tongues of skin and subcutaneous tissue, sometimes including muscle, cut away from the underlying parts but often still attached at one end. They retain their own microvasculature which is also transferred to the new site. They are often used in plastic surgery for filling a defect in a neighboring region.

D014513	Ureter	One of a pair of thick-walled tubes that transports urine from the KIDNEY PELVIS to the URINARY BLADDER.	Ureters
D014517	Ureteral Obstruction	Blockage in any part of the URETER causing obstruction of urine flow from the kidney to the URINARY BLADDER. The obstruction may be congenital, acquired, unilateral, bilateral, complete, partial, acute, or chronic. Depending on the degree and duration of the obstruction, clinical features vary greatly such as HYDRONEPHROSIS and obstructive nephropathy.
