"Urinary tract dilatation and vesicoureteral reflux - Adult outcomes, who should be followed, and how to follow them".

Long-term adult outcomes of children diagnosed with urinary tract dilatation (UTD) and vesicoureteral reflux (VUR) are not clearly documented in the literature. Likewise, follow-up protocols for these patients as they transition through adolescence and into adulthood vary with institution and cultures. Several studies have shown that individuals diagnosed with VUR in childhood are at higher risk of urinary tract infection (UTI) throughout their lives, even in the setting of prior VUR resolution or surgical correction. This is particularly relevant in patients with renal scarring, who are at higher risk of UTIs, hypertension and renal function deterioration in pregnancy. The risk of adverse maternal and fetal outcomes in pregnancy are higher for women with significant chronic kidney disease (CKD). Patients who underwent endoscopic injection or reimplantation should be counselled on the long-term particular risks associated with each intervention, including calcification of ureteric injection mounds, and the potential challenges of future endoscopic procedures following reimplantation. Although there is no evidence for the direct correlation between conservatively managed UTD in childhood, and symptomatic UTD diagnosed in adulthood, all patients should be aware of the long-term risks of persistent upper tract dilatation. Lastly, bladder-bowel dysfunction (BBD) management in adolescence can be more challenging and may contribute to symptomatic recurrence in this age group.
