Outpatient surgery for vesicoureteral reflux: endoscopic injection vs extravesical ureteral reimplantation

Observational, medical or surgical management of vesicoureteric reflux

The clinical management of vesicoureteric reflux includes observational, medical and surgical procedures. The choice of management is often a joint decision made between the paediatric nephrologist and urologist. The use of prophylactic antibiotics has become increasingly debated. In recent years, the surgical treatment of reflux (including endoscopic intervention or ureteral reimplantation) has mainly been limited to cases of high-grade reflux. There are several important risk factors that influence the final outcome which need to be identified and treated. The aim of reflux management is no longer to treat imperatively, but rather to avoid renal damage. It is perhaps time to revise the classic saying 'diagnosed reflux - treated reflux' with a new objective 'diagnosed reflux - evaluated reflux'.

CONCLUSION

The management and follow-up of childhood reflux is a joint decision between the paediatric urologist and nephrologist and should be decided on a case-by-case basis.

[Therapeutic options for primary vesicoureteral reflux: endoscopic vs open surgical approach]

Therapy of vesicoureteral reflux (VUR) has steadily changed during the last decade. Open surgical procedures, e.g. extravesical reflux repair with the Lich-Gregoir technique or ureterocystoneostomy with the psoas hitch technique, reference standards with excellent success rates, are less frequently used. Since its approval by the US Food and Drug Administration (FDA) endoscopic reflux therapy with Deflux® has gained more and more popularity. However, the usage of so-called bulking agents, e.g. Deflux®, still remains controversial in dilating reflux, while its application for low-grade VUR is increasingly being accepted. Despite higher recurrence rates in all grades of VUR, the use of the "minimally invasive injection" is increasing. The question has to be answered which therapy - if necessary - benefits the patient most. Which role has the subureteral injection gained and are open surgical procedures for VUR therapy "out"?
