Introduction:

Duplicated renal collecting system is one of the most common congenital abnormalities of kidney and urinary tract occurring in approximately 0.7- 4% of the population with female predominance. It can be asymptomatic or coexists with other disorders.

 

Material and methods:

The aim of the study was to evaluate the clinical history of paediatric patients hospitalized between 2013 and 2017 with diagnosis of double collecting system.

 

Results:

In five year period 4253 patients were hospitalized, among them 32 children, 25 girls and 7 boys, aged 0 to 17 years, with double collecting system.In 1 child family history was relevant, prenatal suspicion of anomaly in urinary tract was made in 4 cases. In 19 % of the cases duplicated collecting system was bilateral, and in 59 % left kidney was affected. In 7 patients diagnosis was made by abdominal ultrasound without further investigation. Additional tests were performed in patients with abdominal pain, recurrent urinary tract infections and other diseases of urinary system, among them voiding cystourethrography, scintigraphy, and rarely urography/uro-CT. Hydronephrosis or dilated renal collecting system was found in 4 cases, vesicoureteral reflux in 7, ureterocele in 2, ectopic kidney in 1. In 2 patients afunction of second kidney was diagnosed. In 1 of the cases duplicated collecting system of the kidney coexisted with dysmorphic syndrome, in 1 patient with Henoch- Schoenlein disease, in 1 patient with nephrotic syndrome and 1 girl was diagnosed with chronic kidney disease.

 

Conclusions:

Duplicated renal collecting system is found more often in girls and affects left kidney. Children with duplicated renal collecting system need further investigations due to coexistence of other anomalies.
