Abstract

A simple renal cyst usually remains asymptomatic and requires no invasive treatment. Occasionally, however, some cysts may cause pain, hematuria, hypertension, or obstruction of the collecting system. We describe a case of a 50-year-old man who presented with hydronephrosis caused by an ipsilateral simple renal cyst without any stone or significant mass in the urinary system. The patient was eventually treated successfully with sclerotherapy.

  Fig. 1 Sclerotherapy for a simple renal cyst causing hydronephrosis in a 50-year-old man. A. Coronal reformatted contrast-enhanced CT scan shows a renal cortical cyst located at the lower pole of the left kidney (arrows). Note that there is a dilated pelvocalyceal system in the left kidney with perinephric infiltration suggestive of hydronephrosis. B. Antegrade pyelogram through the percutaneous nephrostomy catheter. Contrast media does not pass well through the level of ureteropelvic junction (arrow). C. Antegrade pyelogram after aspiration of the renal cyst through the percutaneous drainage catheter. Contrast media passes well through the ureteropelvic junction (arrow). D. Follow-up CT scan obtained one-month later shows no hydronephrosis in the left kidney and reduction of the size of the renal cyst (arrows).
