Lumenis investigated the reported event by contacting the reporter to request additional information which had been provided.According to the complainant "there was a fragment in the kidney which we saw.We used a number of instruments to try and retrieve.We don't believe that the fragment was in kidney or ureter but possible in bladder or ended up in the navigator."; the procedure was completed by use of a new fiber.A search of the complaint database revealed that no similar complaints of "fiber breaks/fractures" exist for the specified lot.A review of system risk files revealed the following three risks of fibers breaking inside body: risk #1 (1003791_g - risk # 8.1.1) triggered by "user damages fiber external surface during operation" has the potential to lead to prolonged procedure, equipment damage, patient/user/staff injury.Risk #2 (1003791_g - risk # 8.2.1) triggered by "fiber is damaged during shipment" has the potential to lead to prolonged procedure, equipment damage, patient/user/staff injury.Risk #3 (1003791_g - risk # 8.3.1) triggered by "user error (e.G.Excess energy) causes mechanical damage to fiber" has the potential to lead to prolonged procedure, equipment damage, patient/user/staff injury.In each of the aforementioned; the risk has been quantified and found to be negligibly small, and the risk has been characterized and documented as acceptable within full risk assessment.No corrective action or remedial actions were deemed necessary.Subject device was returned to the manufacturer for visual inspection on 25-feb-2019.Initial findings revealed that the "fiber broke while firing.Shows signs of burn marks and a break at 10.1 ft from the sma.Attached to the lab laser in service mode which showed 1.5 hours of use.".Lumenis quality assurance had determined 'operational context' to be the root cause of the reported tip break; the complaint is associated with a product that meets the lumenis design & manufacture specification but due to anatomical/procedural factors encountered during the procedure performance was limited.Lumenis is closing this complaint, but will continue to monitor this failure mode; complaint trending will continue to monitor per global complaint handling sop (doc no.34-01-04-00) and per post marketing surveillance procedure (doc no.1005539).
