Abstrakt:	Renal agenesis occurs in pediatric population with the incidence 1:500- 2000 children. It is more often diagnosed in boys and on the left side of the body. Renal agenesis may be isolated or it may be a part of complex malformation syndrome. Megacalycosis is a very rare anomaly of urinary tract associated with abnormal structure of the kidney pyramids. Aim: The aim of the study was to present for the first time in the medical literature the case of a girl with unilateral renal agenesis and megacalycosis. Case Report: A girl, born at term in good general medical condition, and with normal birth weight was admitted to the hospital because of urinary tract infection caused by E.coli. Antenatal abdominal ultrasounds were normal. In a diagnostic, repeated ultrasound studies, unilateral, left renal agenesis and the righ-sided megacalycosis were found. The right kidney had dilated collecting system, with normal size of renal pelvis and enlarged calyces up to 26 mm. The kidney function was normal. Voiding cystourethrography excluded vesicoureteral reflux. Dynamic scintigraphy 99mTc-EC showed the lack of function of the left kidney, postinflammatory changes and dilation of collecting system without signs of obstruction. During two-years follow up we didn't observe clinical relapse of urinary tract infection. Blood pressure and kidney function were normal. Conclusions: Complex congenital anomalies of the kidney and the urinary tract (CAKUT) can be diagnosed at any age. Normal antenatal abdominal ultrasound does not exclude CAKUT. Every patient with congenital abnormalities of the kidney and the urinary tract requires long-term follow up, because of increased risk of chronic kidney disease. (© 2018 MEDPRESS.)
