Introduction: Megacalycosis is a rare disorder related to congenital underdevelopment of the renal papilla or structural defect of the renal calyces. Megacalycosis has a wide spectrum of clinical presentations ranging from simple variants without any significance on renal function to severe complications. Any prevention strategy is recommended yet since megacalycosis is mostly asymptomatic and usually discovered either accidentally or as result of its complications.

What happens when kidney stone clearance is not feasible? We report the case of a 46-year-old male who presented for review with bilateral congenital non-obstructive calyceal dilatation (megacalycosis) and high volume bilateral renal calculi in the setting of stage four chronic kidney disease. Since complete stone clearance was deemed futile, thus a consensus was made between Urology and Nephrology, and treatment goals were focused on addressing symptoms, preserving renal function and preventing urinary tract infections until renal transplantation is needed. This case highlights that for some patients with severe complex kidney stone disease, an alternative management plan is needed.

The upper urinary tract is the most common human system affected by congenital anomalies. Congenital anomalies of the kidneys and ureters comprise a wide spectrum of disorders ranging from simple variants with no clinical significance to complex anomalies that may lead to severe complications and end-stage renal disease. They may be classified as anomalies of renal form, which are subclassified as structural anomalies (eg, persistent fetal lobulation, hypertrophied column of Bertin, and dromedary hump) and fusion anomalies (eg, horseshoe kidney and pancake kidney); anomalies of renal position (eg, renal malrotation, simple renal ectopia, and crossed renal ectopia) and renal number (eg, renal agenesis and supernumerary kidney); and abnormalities in development of the urinary collecting system (eg, pyelocaliceal diverticulum, megacalycosis, ureteropelvic junction obstruction, duplex collecting system, megaureter, ectopic ureter, and ureterocele).
