Abstract

Background: Calyceal diverticulae and megacalycosis are rare congenital anomalies. The majorities are asymptomatic but they can present with complications. Objective: The objective of this study is to describe the clinical presentations, complications, urographic diagnosis of calyceal diverticulae, megacalycosis, and their treatment. Methods: A descriptive study carried out over 8 years period from March 2012 to December 2019. In three big hospital of Aden province, we collect 15 patients aged from seven to 41 years (mean 13.5 years), our patients were 9 female (60%) and 6 male (40%). They diagnosed incidentally with calyceal diverticulae and megacalycosis by contrasted urography, describing the clinical manifestations, localization, complications, and type of treatment. Results: Sixty percent of patients with calyceal diverticulae and megacalycosis were women and (40%) were men. Clinical manifestations including, dull aching flank and abdominal pain in (40%), acute renal colic (20%), recurrent urinary tract infection (33%), and abdominal pain with a fever of unknown origin in (7%). Calyceal diverticula and megacalycosis were bilateral in (53%) and unilateral in (47%). In the right kidney were (57%), and in the left kidney (43%). In the upper pole of the kidney were (53.3%), middle pole (33.3%), and lower pole (13.3%). Complications occurred in (47%) of patients. They including, urinary stones in (71.4%), hypertension (14.3%), and delayed renal excretion (14.3%). Conservative treatment carried out in (73%) and surgically intervened in (27%). Conclusions: Calyceal diverticula and megacalycosis are rare anomalies. Dull aching flank pain and recurrent urinary tract infections are the most frequent clinical presentations. The most common complications are urinary stones. Conservative treatment is a common type of treatment.
