Strain elastography for noninvasive assessment of liver fibrosis: A prospective study with histological comparison.

The aim of this study was to prospectively evaluate the diagnostic performance of strain elastography for the assessment of liver fibrosis in patients with chronic liver disease using Ishak (0-6) histology stage as a reference standard. Ninety-eight consecutive patients with suspected chronic liver disease scheduled for liver biopsy (n = 78) or histologically confirmed cirrhosis (n = 20) were enrolled. Liver fibrosis Index (LF Index) calculated by strain elastography, liver stiffness by transient elastography and serum fibrosis markers (aspartate aminotransferase-to-platelet ratio index and King's Score) were measured.

Inadvertent discontinuation of percutaneous nephrostomy catheters in adult native kidneys: incidence and percutaneous management.

Purpose: To evaluate the incidence and consequences of complete inadvertent percutaneous nephrostomy catheter discontinuation in native kidneys of adults. In addition, this study evaluated the success rate of nephrostomy tract recannulation.

Materials And Methods: Retrospective analysis was performed in adult patients who underwent percutaneous nephrostomy between January 2000 and December 2005.
