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.
The purpose of the study was to assess the urinary excretion of alpha-GST, pi-GST, NGAL, and KIM-1 and the serum level of NGAL in children with congenital unilateral hydronephrosis
secondary to UPJO.
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 unilateral hydronephrosis
Patients with mild unilateral hydronephrosis
can be managed without surgical intervention and can monitor closely on medical therapy alone.7
We report a case of POUR in a female resulting in severe unilateral hydronephrosis
with perinephric urinoma due to a ruptured fornix.
Because only minor changes in laboratory findings may be observed in patients with unilateral hydronephrosis
, consider renal ultrasonography.
Ultrasonography showed unilateral hydronephrosis
in 52 patients and bilateral in 12.
Using this criterion, contemporary studies demonstrate that only 22% of children with unilateral hydronephrosis
 and 35% with severe bilateral hydronephrosis eventually undergo reconstruction .
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.
