Both the ureteric catheters were normal in position and there was blunting of right costo-phrenic angle due to hydrothorax [Figure 1a]. A chest and abdomen X-ray were carried out, which showed clearing of pleural effusion on the right side and right ureteric catheter was found to be migrated to the right thoracic cavity and left ureteric catheter was found just below the left diaphragm [Figure 1b].
