Unfortunately this can be a frustrating problem. You note that surgery has already been performed as well as chronic antibiotics. Studies have shown that they have roughly equal efficacy and that the decision for either modality should be individualized per patient.
Open surgery is typically used with both nonautologous (Teflon, collagen, silicon microimplants, polyvinyl alcohol, and bioglass) and autologous injectable materials (autologous fat, alginate and chondrocytes, and bladder muscle) being used.
An alternative to open surgery is subureteric Teflon injection (the STING procedure) has been successful in Europe and Japan, but is not approved in the United States. You may want discuss these options with your urologist.
If surgery is not an option, then unfortunately chronic antibiotics would be the most viable option.
