However, these 51 patients had similar bilateral and
unilateral hydronephrosis rates and grade of hydronephrosis in both groups.
An unusual cause of
unilateral hydronephrosis: invasive colonic amebiasis.
Severe primary congenital
unilateral hydronephrosis. A review of 98 cases.
In
unilateral hydronephrosis, an RIR of > 1.1 indicates obstruction.
An ultrasound was considered abnormal if there was documented presence of renal or ureteric stone and/or

Patients with mild

We report a case of POUR in a female resulting in severe

Because only minor changes in laboratory findings may be observed in patients with

Ultrasonography showed

Using this criterion, contemporary studies demonstrate that only 22% of children with

Of the 10 fetuses with follow-up data, the option of termination was offered in 6 cases of anhydramnios, including 3 cases with signs of infravesical obstruction (a possible posterior urethral valve (PUV) and poor prognostic factors and 3 cases with
unilateral hydronephrosis and increased echogenicity in the contralateral kidney.
