Introduction:

 To determine the clinical features and outcomes of children with horseshoe kidney. Horseshoe kidney(HSK)  is the most frequent renal fusion anomalies that seen in 1/400 incidence. Nephrolitihiasis, recurrent urinary tract infection (UTI), hydronephrosis, malignancy can be seen as complications of HSK. 

Material and methods:

 Medical records of the 26 patients were valuated retrospectively.  Age, gender, age at diagnose, clinical presentation (incidentally, antenatally, urinary complaints), follow-up duration, blood pressure, serum creatinine(eGFR), hematuria, proteinuria, UTI, bladder disfunction, ultrasound(US) findings, static cortical scintigraphy(scar, diffential counts), accompaing urinary (VUR, hyronephrosis, obstructive uropathy) and nonurinary anomalies were determined.

Results:

 There were 26 children (17 girls and 9 boys) aged 72 (1-162) months  The mean folow-up duration was 39 (1-132) months. Presenting symptoms were urinary related symptoms in 7 (27%) patients. Ultrasound findings were horseshoe kidney in 12 (46.2%), normal in 5(19.2%), size diffence in size between two kidney in 3 (11.5%), lithiasis in 2 (7.7%), rotation anomaly of he kidney in 1 (3.8%) and hydronephrosis in 1 (3.8%) patient. VUR(Grade 1)  was detected only in 1 (3.8%) patients. Five patient (19.2%) had bladder dysfunction and recurrent UTI. Asymmetrical renal cortical function with a relative function difference >10% between 2 kidneys was found in 9 (34.5%) cases. Hypertension, proteinuria, decrease in eGFR were not detected in any patients. 

Conclusions:

 Most of the patients diagnosed incidentally and ultrasound could detect only half of the patients.  Althought our renal complication rates were low, HSKs should be follow-up for renal complications.
