Title: Clinical characteristics and prognosis of congenital solitary kidney combined with renal damage in children
Abstract: Objective
To analyze the clinical characteristics and the prognosis of congenital solitary kidney in 9 children and to find the causes of renal impairment and factors associated with the prognosis.
Methods
The clinical data of 9 children with congenital solitary kidney in Beijing Children's Hospital Affiliated to Capital Medical University were analyzed, retrospectively.Data of long-term prognosis were collected through follow-up study.
Results
Five girls and 4 boys were involved in the analysis, ranging from 3.9 to 16.0 years old.The mean inpatient age was 9.9 years-old.The patients showed different symptoms in renal impairment of solitary kidney: 9 patients with proteinuria, and 3 of them had manifestation of asymptomatic proteinuria, in the early stage, 3 with abnormalities of renal functions, 3 diagnosed as nephrotic syndrome, and 2 with purpuric nephropathy.In the ultrasound examination of renal morphology, 4 cases had normal echo image, 5 cases had enhanced echo image and 2 patients had developmental malformation of the solitary kidney.The patients received follow-up visits within 1.5 to 7.0 years.The disease deteriorated into chronic kidney disease (stage 4-5) in 3 patients, 1 patient underwent dialysis treatment, 1 patient developed consistent and progressive proteinuria; whereas proteinuria disappeared in 4 patients and renal functions remained normal.
Conclusions
The renal impairment of congenital solitary kidney is mainly manifested as proteinuria, without symptoms in the early stage.In some patients, renal impairment can deteriorate into abnormalities of renal function or renal failure.The early ultrasound screening of the urinary system is recommended.Long-term follow-up should be conducted in children of solitary kidney to find early renal impairment and take appropriate treatment for them, thus to delay the occurrence and deterioration of renal impairment.
