Peritoneography in the diagnosis of peritoneal leaks in peritoneal dialysis.

To the Editor—We read with interest the article entitled “Peritoneal computed tomography: a diagnostic tool for genital oedema in patients on peritoneal dialysis” by Wan et al.1 We agree with the authors that computed tomography (CT) is a very good tool for the diagnosis of inguinal hernia. However, we cannot support the conclusion that a CT scan is the preferred diagnostic tool. In our hospital we use peritoneography with introduction of iodinated contrast (50 mL of Optiray 300; Tyco Healthcare, Sant Joan Despis, Spain) through the peritoneal catheter as the first imaging procedure for diagnosing peritoneal leaks.
