Urolithiasis in an Adult with Primary Obstructive Megaureter: A Case Report

Abstract

This is a rare case of adult primary obstructive megaureter complicated by combined uric acid-oxalate lithiasis of the ureter and renal stones. A 24-year-old male patient presented with frank hematuria on exercise of 4 years duration. The patient had an open surgery in the form of excision of stenotic segment of ureter and left ureteric re-implantation with removal of ureteric and renal stones. Congenital megaureter is a diagnosis that urologists and radiologists need to consider in the setting of isolated distal ureteral dilation, as the diagnosis of adult megaureter may require more involved surgical measures to prevent recurrence of adverse symptoms.

Urolithiasis secondary to primary obstructive megaureter in an adult: a case report

“…In adults, this condition is quite uncommon and only occurs after decades of remaining asymptomatic without any spontaneous regression. Symptoms occur eventually in the event of complications such as recurrent urinary infection, recurrent flank pain, urolithiasis, and kidney function impairment [ 3 , 4 ].…”

“…Diagnosis of POM is greatly dependent on radiological imaging. The criteria for diagnosis of POM includes dilated ureter, lower end of ureter ending in a smooth taper, absence of vesicoureteral reflux (VUR), absence of bladder outlet obstruction, and absence of secondary causes of lower ureteral obstruction [ 4 – 6 ].…”
