Introduction:

 We aimed to evaluate the accompanying urological and urinay anomalies including vesicoureteral reflux(VUR), hypoplasia, urinary tract infection(UTI), hematuria and proteinuria and long-term results of patients who were followed up with a diagnosis of ectopic kidney (EK).

Material and methods:

The files of the patients with EK followed up between 2008-2020 in the outpatient clinics were retrospectively reviewed. Gender, age at presentation, complaints, urinary findings(hematuria, proteinuria), and radiological imaging of the patients were evaluated.

Results:

 The mean age at presentation of 78 cases (F/M=41/37) was 53.42±58.5 (0-274.03) months. 45%(n=35) of the patients were diagnosed incidentally, while 22% (n=17) presented with abdominal pain, 15% (n=12) had antenatal history, 12%(n=9) had UTI and %6.5(n=5) of them applied for voiding disorder. 69%(n=54) of the cases had pelvic, 11%(n=9) had cross EK, and 19%(n=15) had horseshoe kidney. 24%(n=19) of the patients had recurrent UTI. VUR was detected in 9 of these cases. In 35% of the patients (n=25), EKs were hypoplastic. The frequency of hematuria was statistically significantly higher in patients without pelvic EKs (p=0.039). No significant difference was found in terms of age at presentation, follow-up time, current age, size difference between two kidneys on USG between patients with and without hematuria and between those with and without proteinuria. The fractional functions of the kidneys in DMSA were similar between patients with and without hematuria, while having> 10% difference between the two kidneys in DMSA was significantly higher in patients with proteinuria (p=0.023).

Conclusions:

 

Recurrent UTI and VUR can be seen in patients with renal ectopia. Hematuria in non-pelvic EKs and kidneys with high differential difference in DMSA are more common in patients with proteinuria.
