“…3,[5][6][7] This disorder is generally diagnosed during evaluation of nephrolithiasis and/or urinary tract infection. [7][8][9][10][11][12] Obstructive nephropathy and vesicoureteral reflux should be excluded before diagnosing congenital megacalycosis. Ultrasonography, intravenous pyelography, scintigraphy, and computed tomography play important roles in the exclusion of obstructive causes.…”

Congenital megacalycosis is a rare renal disease characterized by calyceal dilatation without pelvic or ureteral obstruction. If not accompanied by nephrolithiasis and urinary tract infection, this disease is completely benign and does not cause renal dysfunction. We present a case of congenital megacalycosis that was diagnosed at the age of 41 (oldest case in the literature) after admitting with hematuria and acute renal dysfunction. IgA nephropathy was also diagnosed in this patient. Since renal dysfunction is not likely in these patients, if encountered; renal biopsy should be performed although technically difficult to diagnose the cause of this dysfunction.

“…The pelvicalyceal system is not grossly dilated in primary megaureters and may appear normal in some cases. [1] The functional aspects of the kidneys remains undisturbed. The ureter usually measures > 7mm to qualify for this entity between 30 weeks fetal gestation and 12 years of age.…”

Bilateral megaureters can present as asymptomatic or symptomatic pathology in the form of flank pain or urinary tract infection. The entity can also be diagnosed in antenatal ultrasound scan. We present 12-year old male child who presented with both flank vague pain and was subjected to ultrasonography (US) and Magnetic Resonance Urography (MRU). There was no evidence of any reflux or obstruction noticed as uretero-vasical junctions were normal on both sides. He was diagnosed as a case of bilateral primary non obstructive megaureters. Base line study was carried out by non radiation modalities in our institute for further follow up.

In der vorliegenden Arbeit wird von einer 42jährigen Frau mit unilateraler Megakalikose berichtet, die wegen Flankenschmerzen mit der Verdachtsdiagnose einer Harnstauungsniere li. stationär aufgenommen wurde. Bei der Megakalikose handelt es sich um eine nichtobstruktive Dilatation der Nierenkelche, bedingt durch Hypoplasie der Markpyramiden ungeklärter Ätiologie. Sie betrifft meist nur eine Seite und ist nicht Folge eines Refluxes, einer Papillennekrose oder chronischen Infektion. Die Niere weist eine normale Funktion auf. Eine operative Korrektur ist nicht erforderlich. Die Therapie besteht in der Behandlung der Komplikationen und deren Prophylaxe. Einleitung
