In pilot work, we showed that somatic nerve transfers can restore motor function in long-term decentralized dogs. We continue to explore the effectiveness of reinnervation 30 female After anesthesia, 12 underwent bilateral transection coccygeal and sacral (S) spinal roots, dorsal roots lumbar (L)7, hypogastric nerves. Twelve months postdecentralization, eight transfer obturator branches pelvic vesical branches, sciatic pudendal nerves, followed by 10 mo recovery (ObNT-ScNT Reinn). The...
ABSTRACT Many studies examining the innervation of genitourinary structures focus on either afferent or efferent inputs, only one structure system. We aimed to clarify bladder, external urethral sphincter (EUS) and clitoris. Retrograde dyes were injected into each end organ in female dogs. Spinal cord, mid‐bladder, spinal, caudal mesenteric, sympathetic trunk pelvic plexus ganglia examined for retrograde dye‐labeled neurons. Neurons retrogradely labeled from bladder found primarily L7‐S2...
Previous patient surveys have shown that patients with spinal cord or cauda equina injuries prioritize recovery of bladder function. The authors sought to determine if nerve transfer after long-term decentralization restores and sphincter function in canines.
Aims Lumbar to sacral rerouting surgery can potentially allow voiding via a skin‐central nervous system‐bladder reflex pathway. Here, we assessed if this was effective in treating neurogenic bladder dysfunction/sphincter felines. Methods Eight cats underwent spinal cord transection (SCT) at thoracic level 10/11. Unilateral L7 S1 ventral root anastomosis performed 1 month later six cats. Two served as transection‐only controls. Electrical and manual stimulation of L6‐S1 dermatomes,...
This study determined the effect of pelvic organ decentralization and reinnervation 1 yr later on contribution muscarinic purinergic receptors to ex vivo, nerve-evoked, bladder smooth muscle contractions. Nineteen canines underwent by bilateral transection all coccygeal sacral (S) spinal roots, dorsal roots lumbar (L)7, hypogastric nerves. After exclusions, 8 were reinnervated 12 mo postdecentralization with obturator-to-pelvic sciatic-to-pudendal nerve transfers then euthanized 8-12 later....
We determined the effect of pelvic organ decentralization and reinnervation 1 yr later on urinary bladder histology function. Nineteen canines underwent by bilateral transection all coccygeal sacral (S) spinal roots, dorsal roots lumbar (L)7, hypogastric nerves. After exclusions, eight were reinnervated 12 mo postdecentralization with obturator-to-pelvic sciatic-to-pudendal nerve transfers, then euthanized 8-12 later. Four served as long-term decentralized only animals. Before euthanasia, or...
Spinal interneurons play a critical role in motor output. A given interneuron may receive convergent input from several different sensory modalities and descending centers relay this information to just as many targets. Therefore, there is need quantify populations of spinal simultaneously. Here, we the functional connectivity neurons through concurrent recording lumbar hindlimb units vivo cat model during activation either ipsilateral sural nerve or contralateral tibial nerve. Two...
Aims To assess bladder smooth muscle function and innervation after long‐term lower spinal root transection in canines. Methods Thirteen female mixed‐breed hound dogs underwent decentralization, which included of all sacral dorsal ventral roots caudal to L7 hypogastric nerves, bilaterally ( n = 3); nerves plus roots, 4); or a sham operation 6). At year initial surgery, was assessed vivo by stimulation the pelvic plexus. The tissue harvested for ex contractility studies. Remaining evaluated...
Very little is known about the physiological role of nicotinic receptors in canine bladders, although functional have been reported bladders many species. Utilizing vitro methods, we evaluated mediating bladder function dogs: control (9 female and 11 male normal controls, 5 sham operated), Decentralized females, decentralized 6-21 mo), obturator-to-pelvic nerve transfer reinnervated (ObNT-Reinn; 9 females; 9-13 mo, then with 8-12 mo recovery). Muscle strips were collected, mucosa-denuded,...
Objective We aimed to refine electroneurogram techniques for monitoring hypogastric nerve activity during bladder filling, and then examined in normal intact versus acutely decentralized bladders. Methods Effects of electrical stimulation nerves or lumbar ventral roots on detrusor pressure were examined, as effects isoflurane propofol anesthetics evoked pressure. Hypogastric was recorded using custom-made bipolar cuff electrodes filling before after its transection between the spinal cord...

This study aimed to identify potential lateralization of bladder function. Electrical stimulation spinal roots or the pelvic nerve’s anterior vesical branch was performed bilaterally in female dogs. The percent difference between left and right stimulation-induced increased detrusor pressure determined. Bladders were considered right-sided if differences greater less than 25% 10%. Based on 25%, upon roots, bladders left-sided 17/44 (38.6%), 12/44 (27.2%) bilateral 15/44 (34.2%). Using ± 10%,...
