Simple parameters predicting extrahepatic recurrence after curative hepatectomy for hepatocellular carcinoma.

Extrahepatic recurrence (EHR) after curative hepatectomy for hepatocellular carcinoma (HCC) is associated with a poor prognosis. We investigated the features of EHR and identified its predictive factors. This retrospective study included 398 treatment-naive patients who underwent curative hepatectomy for HCC at two tertiary hospitals.

Are Urologists Performing Semi-rigid Ureteroscopic Lithotripsy Safe From Radiation Exposure? A Guidance to Reduce the Radiation Dose.

Objective: To measure radiation exposure of urologists during ureteroscopic (URS) lithotripsy, and hence estimating the number of procedures that can be performed safely considering the annually permissible radiation dose, and to identify influential variables.

Materials And Methods: The radiation exposure dose was measured at the neck, chest, arm, and hands of a single urologist who performed 49 URS lithotripsies. The number of annually performed URS lithotripsies was estimated based on the annual permissible occupational exposure radiation dose guidelines.
