Dilated Ureter 3 (UTI/VUR)

harn_17a_n.jpg to harn_17e_n.jpg: Ultrasound and IVU of the upper urinary tract and the kidney on follow-up in a 2-month-old boy with the diagnosis of megaureter. harn_17a_n.jpg and harn_17b_n.jpg: Longitudinal slice of the kidney and bladder on ultrasound at the age of 2 months; the pelvicocaliceal system of the visible renal segment is dilated and the ipsilateral ureter is visible as an elongated structure which is close to the bladder and also dilated. harn_17c_n.jpg and harn_17d_n.jpg: IVU at the age of 9 months; the renal pelvis is dilated, and the calices are deformed in the upper group and in some of the middle group; the prevesical ureter is dilated and becoming tapered in the direction to the bladder. harn_17e_n.jpg: Ultrasound at the age of 6.7 years; normalization of the pelvicocaliceal system of the involved kidney; the ipsilateral ureter is not visible anymore in the ultrasound, corresponding to a normal calibre. harn_17a_n.jpg to harn_17e_n.jpg: The diagnosis is a reversible and non-obstructive (or only temporarily obstructive) megaureter which did not need surgery. Such follow-ups may also be observed in ureteropelvic junction obstruction. Non-operative treatment is only allowed if no obvious obstruction is present, no reduction of renal function occurs, the dilatation of the upper urinary tract is not progressive, and if no recurrent UTI or break-through infections are observed.
