Block f10: problem code 2976 captures the reportable event of stent kinked during stent removal.Patient code 2001 captures the reportable event of perforation in ureter.Block h6: conclusion code 4316 is being used in lieu of an adequate conclusion code for device not returned.Block h10: the device was received and product analysis was completed a visual evaluation was performed on the returned device.The proximal section (bladder pigtail) was found to be buckled/accordion, moreover, calcification were found at several locations of the stent.A functional inspection was performed, a mandrel 0.038" was inserted through the stent and resistance was met during its advancing due to the section encountered as buckled/accordion.All compiled information on this investigation determines that the most probable cause for the reported perforation, ureter/urethra and the encountered issue of cause is known inherent risk of device since reported adverse event known and documented in the labeling (including both short or long term known complications or adverse reactions).Based on the product analysis, the device has the working length buckled, however, this failure is known to be generated due to the force used when the stent is pushed up with the pusher/positioner over the guidewire; therefore, it is the most likely that it was generated due to the manipulation of the device or due to the interaction with other devices during the preparation.Therefore, the most probable cause of this complaint is adverse event related to procedure since it is the most likely that the adverse event occurred during the preparation and the device had no influence on event.A review of the device history record (dhr) was performed; no anomalies were found.
