Polycystic Renal Disease Presented by Anuria and Nephrolithiasis Associated Progressive Kidney Damage: A Case Report

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most common inherited kidney disease. Kidney stones develop in 20-30% of patients with ADPKD.Hydronephrosis, which is the most valuable radiological finding in the diagnosis of stone-related postrenal insufficiency, may be difficult to differentiate from common cysts in ADPKD patients. When kidney dysfunction develops in ADPKD patients, Glomerular Filtration Rate (GFR) loss reaches an average of 4.4 to 5.9 mL / min per year. Faster deterioration in these patients requires investigation for prerenal factors such as dehydration that triggers acute kidney damage or stone-related postrenal factors. In ADPKD, stone-related postrenal obstruction should be considered in rapid GFR losses despite negative ultrasound report for hydronephrosis as there is frequent occurrence of kidney stones and the difficulty in detecting hydronephrosis with ultrasonography (US) in these patients. Here, we present a case with ADPKD whose renal functions rapidly deteriorated while under chronic follow-up and renal function markers returned to the basal levels with the treatment of the underlying cause.
