The importance of ultrasonographic measurement of peritoneal wall thickness in pediatric chronic peritoneal dialysis patients.

Loss of peritoneal function due to peritoneal fibrosing syndrome (PFS) is a major factor leading to treatment failure in chronic peritoneal dialysis (PD) patients. Although the precise biologic mechanisms responsible for these changes have not been defined, the general assumption is that alterations in peritoneal function are related to structural changes in the peritoneal membrane. Studies of the peritoneal membrane by non-invasive ultrasonography (US) in chronic PD patients are limited.

A single-center experience on percutaneously performed partial omentectomy in pediatric peritoneal dialysis patients.

Objective: This study describes a single-center experience on percutaneously performed partial omentectomy procedure in pediatric peritoneal dialysis (PD) patients who showed early catheter dysfunction and required catheter replacement due to catheter flow obstruction.

Materials And Methods: We performed a retrospective review of clinical outcomes from pediatric PD patients who underwent percutaneous catheter replacement by pediatric nephrologists between November 1995 and December 2012. Partial omentectomy was performed in those patients in whom omental or adhesion trapping to the catheter tip was seen.
