Abstract
This study aimed to identify potential lateralization of bladder function. Electrical stimulation of spinal roots or the pelvic nerve’s anterior vesical branch was performed bilaterally in female canines. The percent difference between the left and right stimulation-induced increased detrusor pressure was determined. Bladders were considered left or right-sided if differences were greater or less than 25% or 10%. Based on differences of 25%, upon stimulation of spinal roots, bladders were left-sided in 17 (38.6%), right-sided in 12 (27.2%) and bilateral in 15 (34.2%). Using  10%, 48% had left side dominance (n = 21), 39% had right side dominance (n=17), and 14% were bilateral (n = 6). With stimulation of the pelvic nerve’s anterior vesical branch in 19, bladders were left-sided in 8 (42.1%), right-sided in 6 (31.6%) and bilateral in 5 (26.3%) using 25% differences and left side dominance in 8 (43%), right sided in 7 (37%) and bilateral in 4 (21%) using 10% differences. These data suggest lateralization of innervation of the female canine bladder with left- and right-sided lateralization occurring at similar rates. Lateralization often varied at different spinal cord levels within the same animal.
Description
An excel file is provided that includes the raw data for analyses shown in Figures 2 and 3 of a paper entitled: Lateralization of Bladder Function in Normal Female Canines, by Giaddui et al. Tab 1 of the excel file provides raw data for Figure panel 2A (Maximum detrusor pressure after all spinal root stimulation). Tab 2 provides raw data for Figure panels 2B-F (Maximum detrusor pressure after stimulation of L6-S3 spinal roots). Tab 3 of the excel file provides raw data of the maximum detrusor pressure after anterior vesical branch of pelvic nerve stimulation.
