Stimulation of the sacral ventral roots with the largest detrusor representation was found to be moderately successful for bladder emptying in acute canine experiments. However, removal of spinal reflexes arising from sacral root stimulation did not eliminate sphincteric resistance. For that reason ventral roots were stimulated after peripheral somatic neurotomy. Unilateral pudendal nerve sectioning was compared with selective sectioning of the somatic fibers of S2, the root with the greatest detrusor representation in canines. Both were equally effective in significantly reducing outlet resistance. Selective nerve section has one advantage: it preserves more of the nerve pathways involved in reflexogenic erection.
在急性犬实验中，刺激具有最大逼尿肌代表区的骶前根对膀胱排空有一定程度的成功。然而，消除由骶神经根刺激引起的脊髓反射并不能消除括约肌阻力。因此，在周围躯体神经切断术后刺激前根。将单侧阴部神经切断与选择性切断犬中具有最大逼尿肌代表区的S2神经根的躯体纤维进行比较。两者在显著降低出口阻力方面同样有效。选择性神经切断有一个优点：它保留了更多参与反射性勃起的神经通路。
