Intraoperative Bulbocavernosus Reflex Monitoring for Predicting Bowel Function After Resection of Conus Medullaris and Cauda Equina Tumors

< 0.001), respectively. Cross-validation confirmed these thresholds, with mean AUC values of 0.992 and 0.993 for short-term and long-term PBD, respectively.ConclusionsThe ARR of the intraoperative BCR waveform showed a high predictive value for PBD in patients with CMCET. We propose a 60% ARR reduction on either side of the BCR waveforms as an exploratory, hypothesis-generating early warning criterion for BCR monitoring during CMCET surgery, pending external validation in independent prospective cohorts before clinical implementation.
