two year outcome of percutaneous bipolar radiofrequency neurotomy of Sacral Nerves s2 and s3 in spinal cord injured patients with neurogenic detrusor overactivity a randomized controlled feasibility study
Pain Physician, 2016Co-Authors: Hyo Sung Kim, Yun Woo Cho, Sang Ho AhnAbstract:BACKGROUND Little research has been expended on the use of bipolar radiofrequency (RF) lesioning of Sacral Nerves in spinal cord injured (SCI) patients with neurogenic detrusor overactivity (NDO), and no study has been undertaken to demonstrate its long-term effect. OBJECTIVE To investigated the effect of bipolar RF ablation of the second and third Sacral Nerves over 2 years in SCI patients with NDO. STUDY DESIGN A prospective, randomized controlled feasibility study. SETTING The outpatient clinic of a single academic medical center in Korea. METHODS Ten SCI patients with NDO were recruited. These patients were randomly assigned to 2 groups; the intervention group (n = 5) and the control group (n = 5). Control group members received optimized conventional treatment. International Consultation on Incontinence Questionnaire (ICIQ), 3-day voiding diary, and the urinary incontinence quality of life scale (I-QOL) data were obtained at baseline and at 6, 12, and 24 months after intervention. Urodynamic study (UDS) was performed at baseline and 24 months after intervention. In the intervention group, percutaneous bipolar RF neurotomy was performed on both S2 and S3 Nerves in each patient. RESULTS Frequency of urinary incontinence and ICIQ and IQOL scores showed significant effects for time and for the group x time interaction (P < 0.05). Daily mean volume of urinary incontinence showed only a significant group effect. In UDS parameters, comparisons of values at baseline and at 24 months revealed all variables showed significant intergroup differences (P < 0.05). LIMITATION A small number of patients was recruited. CONCLUSION Percutaneous bipolar RF ablation of Sacral Nerves S2 and S3 effectively reduces urinary incontinence and improves quality of life (QoL) in SCI patients with NDO and the effects lasted over 2 years.

the lumboSacral plexus of the red rumped agouti dasyprocta leporina linnaeus 1758 rodentia caviidae
Semina-ciencias Agrarias, 2016Co-Authors: Gleidson Benevides De Oliveira, Helio Noberto De Araujo, Paulo Mateus Alves Lopes, Herson Da Silva Costa, Radan Elvis Matias De Oliveira, Carlos Eduardo Bezerra De Moura, Valeria Veras De Paula, Moacir Franco De OliveiraAbstract:The red-rumped agouti is a small-sized wild rodent, belonging to the Dasyproctidae family, with great zootechnical potential, and it adapts well to captivity. In order to contribute to the species biology, this study describes the origin of the Nerves forming the lumboSacral plexus. Twelve animals (six males and six females) were used, from previous experiments. The animals were fixed in a 10% formaldehyde aqueous solution and eviscerated after 72 hours. Then, the major and minor psoas muscles were retracted, exposing the Nerves forming the plexus. Cotton soaked with 20-volume hydrogen peroxide was placed on these Nerves, remaining for 12 hours straight for bleaching and subsequent dissection. The topographical relations of the lumboSacral plexus were grouped into tables and arranged in terms of simple percentage. In 7 cases (58.34%), the lumboSacral plexus in the red-rumped agouti stemmed from the ventral roots of the last 4 lumbar Nerves and the first 3 Sacral Nerves (Type I – L 4 -S 3 ), in 4 animals (33.33%) it stemmed from L 5 -S 3 (Type II), and in 1 case (8.33%) it stemmed from L 5 -S 4 (Type III). The Nerves participating of the lumboSacral plexus in the red-rumped agouti were: lateral femoral cutaneous, genitofemoral, femoral, obturator, sciatic, cranial gluteal, caudal gluteal, and pudendal nerve. The origin of the lumboSacral plexus and the spinal Nerves making up this plexus in red-rumped agoutis were similar to that described in other rodents, such as rock cavy, lowland paca and spix's yellow-toothed cavy.

lumboSacral plexus of the mongolian gerbil meriones unguiculatus milne edwards 1867 plexo lombosSacral do gerbil meriones unguiculatus milne edwards 1867
Bioscience Journal, 2016Co-Authors: Helio Noberto De Araujo, Gleidson Benevides De Oliveira, Herson Da Silva Costa, Carlos Eduardo Bezerra De Moura, Valeria Veras De Paula, Amilton Cesar Dos Santos, Diego Carvalho Viana, Moacir Franco De OliveiraAbstract:The Mongolian gerbil, belonging to the Muridae family, is characterized as an economic asset in the pet market due to its easy management. Current research analyzes and describes the origin of the Nerves that make up the lumboSacral plexus in the species, foregrounding comparative anatomy, especially among wild rodents. The experiment, approved by the Committee of Institutional Bioethics, involved 15 animals which had been used in other studies and were donated to the Laboratory of Applied Animal Morphophysiology of the Federal Rural University of the Semi-Arid, Mossoro, Rio Grande do Norte, Brazil. The animals were fixed in a water solution of formaldehyde 10%. After 72 hours, they were dissected, the abdominal cavity was opened and eviscerated, and the psoas minor, psoas major and the quadratus lumborum muscles were removed to inspect the Nerves that form the lumboSacral plexus. Results were given in percentages and grouped in tables. The lumboSacral plexus of the Mongolian gerbil frequently derived from the ventral roots of the last thorax Nerves, from the seven lumbar Nerves and from the four Sacral Nerves (Type II – T 12 -S 4 ). The Nerves of the gerbil´s lumboSacral plexus are the iliohypogastricus, ilioinguinalis, cutaneus femoris lateralis, genitofemoralis, femoralis, obturatorius, ischiadicus, gluteus cranialis, pudendus, gluteus caudalis and rectales caudales Nerves. Information on the origin of the Nerves of the gerbil´s lumboSacral plexus and their description is relevant for clinical and surgical studies, and for the application of techniques or anesthetic drugs.

origin of the lumboSacral plexus in galea spixii wagler 1831 rodentia caviidae
Biotemas, 2014Co-Authors: Gleidson Benevides De Oliveira, Marcio Nogueira Rodrigues, Rejane Dos Santos Sousa, Carlos Eduardo, Bezerra De Moura, Maria Angelica Miglino, Moacir Franco De OliveiraAbstract:The yellow-toothed cavy is a rodent belonging to the Caviidae family that inhabits the semiarid region of northeastern Brazil. We used 20 cavies that had died of natural causes, obtained from the Reproduction Center of Wild Animals (CEMAS) of the Federal Rural University of the Semi-Arid (UFERSA). The animals were ixed in aqueous solution of 10% formaldehyde and, after 48 hours, they were dissected to visualize plexus. The topographic relations of the lumboSacral plexus were grouped into tables and then they underwent statistical analysis (chi-square test with Yates’ correction). The lumboSacral plexus stemmed from the ventral roots of the last 3 lumbar Nerves and the irst 3 Sacral Nerves, corresponding to 65% of the animals under study (L L 6 L 7 S 1 S 2 S 3 ). These Nerves stemmed from plexus: femoral, obturator, ischiatic, cranial gluteal, caudal gluteal, and pudendal.

A step towards stereotactic navigation during pelvic surgery: 3D nerve topography
2018Co-Authors: Wijsmuller A.r., Giraudeau C., Leroy J., Kleinrensink, G.j. Jan), Romagnolo, L.g. G.), Melani, A.g.f. G.f.), Diana M., Rociu Elena, Soler L.Abstract:textabstractBackground: Long-term morbidity after multimodal treatment for rectal cancer is suggested to be mainly made up by nerve-injury-related dysfunctions. Stereotactic navigation for rectal surgery was shown to be feasible and will be facilitated by highlighting structures at risk of iatrogenic damage. The aim of this study was to investigate the ability to make a 3D map of the pelvic Nerves with magnetic resonance imaging (MRI). Methods: A systematic review was performed to identify a main positional reference for each pelvic nerve and plexus. The Nerves were manually delineated in 20 volunteers who were scanned with a 3-T MRI. The nerve identifiability rate and the likelihood of nerve identification correctness were determined. Results: The analysis included 61 studies on pelvic nerve anatomy. A main positional reference was defined for each nerve. On MRI, the Sacral Nerves, the lumboSacral plexus, and the obturator nerve could be identified bilaterally in all volunteers. The sympathetic trunk could be identified in 19 of 20 volunteers bilaterally (95%). The superior hypogastric plexus, the hypogastric nerve, and the inferior hypogastric plexus could be identified bilaterally in 14 (70%), 16 (80%), and 14 (70%) of the 20 volunteers, respectively. The pudendal nerve could be identified in 17 (85%) volunteers on the right side and in 13 (65%) volunteers on the left side. The levator ani nerve could be identified in only a few volunteers. Except for the levator ani nerve, the radiologist and the anatomist agreed that the delineated nerve depicted the correct nerve in 100% of the cases. Conclusion: Pelvic Nerves at risk of injury are usually visible on high-resolution MRI with dedicated scanning protocols. A specific knowledge of their course and its application in stereotactic navigation is suggested to improve quality of life by decreasing the likelihood of nerve injury
