Abstract
The object of this work was to study bulbocavernosus and deep pudendal reflex (BCR and DPR) latencies and amplitudes as an indicator of pelvic nerve damage in patients with pelvic floor disorders, with or without a previous surgery. 124 women were studied: 68 were normal, 38 had genital prolapse (GP) and 18 had recurrent GP. Clinical and urodynamic studies were carried out. Delayed reflex responses were found in 44/56 patients (79%), 27/38 in the genital prolapse group (71%) and 17/18 in the group with recurrent GP (94%). Thus the evaluation of pelvic floor reflex responses is a test that can be taken into account in the diagnosis of management of pelvic floor disorders.
