Electromyography needle breaks within the perineum: a rare complication of urodynamics not reported earlier and lesson learnt

The urodynamic study (UDS) is nowadays frequently used by the urologist worldwide to aid in the diagnosis of various urological disorders and electromyography (EMG) is an integral part of it. EMG is performed either by using surface electrodes or concentric needle electrodes. We report an unusual case in which the concentric EMG needle was accidentally broken within the perineum of a man aged 60 years undergoing urodynamics. The needle was removed urgently in a minimally invasive manner under the C-arm guidance without any associated morbidity. This case report highlights the need of urgent intervention in such rare scenarios to help prevent any associated infectious complications. Also, vigilant behaviour during the procedure (and after) to detect such incidents along with detailed patient counselling should be included in the patient management protocol of patients undergoing UDS.
