本研究旨在确定膀胱功能的潜在偏侧化。对雌性犬的双侧脊髓根或盆腔神经膀胱前支进行电刺激。确定左右刺激引起的逼尿肌压力增加之间的百分比差异。如果差异大于或小于 25% 或 10%，则膀胱被视为左侧或右侧。基于 25% 的差异，在刺激脊髓根时，膀胱为左侧 17/44 (38.6%)，右侧为 12/44 (27.2%)，双侧为 15/44 (34.2%)。使用 ± 10%，48% 为左侧优势 (n = 21/44)，39% 为右侧优势 (n = 17/44)，14% 为双侧优势 (n = 6/44)。在 19 只狗中刺激盆腔神经膀胱前支后，膀胱为左侧 8 只（42.1%）、右侧 6 只（31.6%）、双侧 5 只（26.3%），差异为 25%；左侧占优势的有 8 只（43%）、右侧为 7 只（37%）、双侧为 4 只（21%），差异为 10%。这些数据表明母狗膀胱神经支配的偏侧化，左侧和右侧偏侧化的发生率相似。同一动物的不同脊髓水平的侧化通常有所不同。
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 dogs. 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 17/44 (38.6%), right-sided in 12/44 (27.2%) and bilateral in 15/44 (34.2%). Using ± 10%, 48% had left side dominance (n = 21/44), 39% had right side dominance (n = 17/44), and 14% were bilateral (n = 6/44). With stimulation of the pelvic nerve’s anterior vesical branch in 19 dogs, 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 dog bladder with left- and right-sided lateralization occurring at similar rates. Lateralization often varied at different spinal cord levels within the same animal.
