Study design: Retrospective with prospective follow-up. Objective: Confirming the diagnosis of CES based purely on symptoms and signs is unreliable and usually associated with high false positive rate. A missed diagnosis can permanently disable the patient. Present study aims to determine the relationship between clinical symptoms/ signs (bladder dysfunction) with UDS, subsequently aid in surgical decision making and assessing post-operative recovery. Methods: A prospective follow-up of patients with disc herniation and bladder symptoms from January 2018 to July 2020 was done. All patients underwent UDS and grouped into acontractile, hypocontractile and normal bladder. Data regarding PAS, VAC, GTP, timing to surgery and onset of radiculopathy and recovery with correlation to UDS was done preoperatively and post operatively. Results: 107 patients were studied (M-63/F-44). Patients with PAS present still had acontractile (61%) or hypocontractile (39%) detrusor and with VAC present, 57...

Timing of surgery and the importance of the size of disc prolapse in cauda equina syndrome (CES) remain controversial. To investigate whether there is a relationship between postoperative urinary function, preoperative duration of neurogenic lower urinary tract dysfunction (NLUTD), and the level of canal compromise. Seventy-one patients operated for CES were prospectively identified between 2010 and 2013. Fifty-two cases with preoperative NLUTD were included. The "Prolapse: Canal ratio" (PCR) was calculated as a proportion of cross-sectional area of disc prolapse on total cross-sectional area of spinal canal. Median of preoperative duration of NLUTD was 72 h (48; 132) and period from first assessment to surgery 10.5 h (7; 18.5). Urinary incontinence was seen in 46.2% of patients, 38.4% had painless retention and 15.4% had painful retention. In 38.5% of cases, urinary symptoms persisted for more than 20 mo postoperatively. There was no correlation between duration of preope...

Background: Cauda equina syndrome (CES) is rare neurosurgical emergency requiring emergent surgical decompression to prevent bladder, bowel, and sexual dysfunction that can have significant impact on quality of life. There is a paucity of data relating to the prevalence of these long-term complications. Objective: The aim of this observational study was to evaluate the long-term prevalence of CES-related bladder, bowel, and sexual dysfunction and impact on quality of life to inform service provision. Methods: Participants were selected through coding of operative records of patients who underwent lumbar decompression for CES secondary to a herniated intervertebral disc at two large UK neurosurgical departments between 2011 and 2015 inclusive. A telephone-based survey including both validated and modified tools was used to collect data pertaining to bladder, bowel, and sexual function and impact on quality of life both before development of CES and at the time of the survey, at least...
Cauda equina syndrome due to disk herniation: Long-term functional prognosis
Neurocirugía, 2019
Objective: Cauda equina syndrome (CES) caused by lumbar disk extrusion is classically considered an indication of urgent surgery. CES can be subdivided into CESI (incomplete CES) and CESR (complete CES with urinary retention and incontinence). This paper evaluates the long-term functional outcome of a CES cohort operated on due to disk herniation. Methods: Single-center retrospective observational study. CES patients due to disk herniation that underwent surgery between 2000 and 2016 were included in the study. Demographic data, time intervals to diagnosis and surgery, preoperative neurologic status and outcome at the end of follow up were recorded. Results: Twenty-two patients were included (median age 44 years). Eight patients were CESR and 14 CESI. Median time from symptom onset to diagnosis was 78 h (range, 12-720 h), and from diagnosis to surgery 24 h (range, 5-120 h). Median follow up was 75 months (range, 20-195 months). At the end of follow up, in the CESR group (median time from diagnosis to surgery, 23 h) only pain significantly improved after surgery (p = 0.007). In the CESI group (median time from diagnosis to surgery 23 h) low back pain, sciatica and urinary sphincter function significantly improved (p < 0.001). There were no significant differences between early (<48 h) operation (n = 4) and late (n = 18) in terms of sphincter recovery (Fisher's Exact Test, p = 0.076). Conclusion: Pain associated to CES improved both in the CESI and CESR groups. However, urinary sphincter impairment significantly improved only in the CESI group. No significant differences were found regarding long-term functional outcome between early and late surgery.

Objective: to discuss two cases with CES-induced acute urinary retention, knowledge of which is essential for early diagnosis, treatment and prevention of neurological dysfunctions. Case presentation: Two patients were hospitalized with symptoms lower back pain with weakness and progressive loss of feeling of lower limbs accompanied by acute urinary retention, urinary system tests were within normal limits. Magnetic resonance imaging results in lumbar disc herniation causing spinal stenosis. Both patients underwent posterior lumbar interbody fusion (PLIF) procedure and showed improvements in symptoms after surgery and re-examination.Conclusion: The diagnosis should be based on magnetic resonance imaging. Lumbar disc herniation is the most common cause of acute urinary retention from cauda equina compression. Laminectomy, with early decompression within 24 to 48 hours, reduces the risk of long-term neurological dysfunction and increases the chances of recovery for the patient.

Aim To analyze the relationship between timing of surgery and outcome in patients with cauda equina syndrome caused by lumbar disc herniation. Methods A retrospective, non-randomized clinical study included 25 consecutive patients with cauda equina syndrome (CES) caused by lumbar disc herniation. All patients were operated within 24 hours after hospitalization at the Department of Neurosurgery, Cantonal Hospital Zenica, Bosnia and Herzegovina, between January 2000 and December 2010. All patients were evaluated before surgery on the basis of complete history, neurological examination and neuroimaging evaluations using CT (computed tomography)and MRI (magnetic resonance imaging). Results Statistically significant difference between preoperative and postoperative bladder (p=0.05) and bowel (p=0.05) function was found. A significant number of patients had bladder and bowel recovery after surgery, nine (36%) and 11 (44%), respectively. Significant recovery of muscle strength was noted wi...
Cauda equina syndrome treated by surgical decompression: the influence of timing on surgical outcome
European Spine Journal, 2007
A prospective longitudinal inception cohort study of 33 patients undergoing surgery for cauda equina syndrome (CES) due to a herniated lumbar disc. To determine what factors influence spine and urinary outcome measures at 3 months and 1 year in CES specifically with regard to the timing of onset of symptoms and the timing of surgical decompression. CES consists of signs and symptoms caused by compression of lumbar and sacral nerve roots. Controversy exists regarding the relative importance of timing of surgery as a prognostic factor influencing outcome. Post-operative outcome was assessed at 3 months and 1 year using the Oswestry Disability Index (ODI), Visual Analogue Scale (VAS) scores for leg and back pain and an incontinence questionnaire. Statistical analysis was used to determine the association between pre-operative variables and these post-operative outcomes with a specific emphasis on the timing of surgery. Surgery was performed on 12 (36%) patients within 48 h of the onset of symptoms including seven patients (21%) who underwent surgery within 24 h. Follow up was achieved in 27 (82%) and 25 (76%) patients at 3 and 12 months, respectively. There was no statistically significant difference in outcome between three groups of patients with respect to length of time from symptom onset to surgery-\24, 24-48 and [48 h. A significantly better outcome was found in patients who were continent of urine at presentation compared with those who were incontinent. The duration of symptoms prior to surgery does not appear to influence the outcome. This finding has significant implications for the medico-legal sequelae of this condition. The data suggests that the severity of bladder dysfunction at the time of surgery is the dominant factor in recovery of bladder function.
Does Early Surgical Decompression in Cauda Equina Syndrome Improve Bladder Outcome?
Spine, 2015
We analyzed retrospectively whether early surgery for cauda equina syndrome (CES) within 24, 48, or 72 hours of onset of autonomic symptoms made any difference to bladder function at initial outpatient follow-up. Objective. CES potentially causes loss of autonomic control including bladder dysfunction, resulting in signifi cant disability. There is signifi cant debate regarding appropriate timing of surgery. Summary of Background Data and Methods. We conducted a retrospective cohort study of 200 patients between 2000 and 2011 who underwent decompressive surgery for CES at a regional neurosurgical center. Data collected were from clinical admission and at initial follow-up. Presentation was categorized into CES with retention (CESR) and incomplete CES (CESI) and duration of autonomic symptoms before surgical intervention. Results. A total of 200 patients had complete clinical records; 61 cases with CESR and 139 cases with CESI. Average initial follow-up time was 96 days. For the 36 cases with CESI less than 24 hours, normal bladder function was seen at follow-up in all patients except 4 (11.1%), but with 103 cases with CESI more than 24 hours, 48 (46.6%) had bladder dysfunction (Pearson χ 2 P = 0.000). For the 64 cases with CESI less than 48 hours, normal bladder function was seen at follow-up in all except 10 (15.6%), but with 75 cases with CESI more than 48 hours, 42 (56%) had bladder dysfunction (Pearson χ 2 P = 0.000). For the 35 patients with CESR, operating within 24, 48, or 72 hours made no obvious difference to bladder outcome. Data were also reanalyzed changing the dataset groups to CESI less than 24 hours, 24 to 48 hours, and more than 48 hours to calculate odds ratios regarding normal bladder outcome.
Prognosis of Cauda Equina Syndrome Caused by Herniated Disk After Lumbar Disk Operation
Background and Aim: Although operation is the most appropriate treatment for Cauda Equina Syndrome, the effectiveness of operation on clinical symptoms is still under discussion. This study aimed to determine the prognosis of Cauda Equina Syndrome in patients with lumbar disk surgery in Al-Zahra Hospital of Isfahan City, Iran, from 2013 to 2015. Methods and Materials/Patients: In This prospective study, patients diagnosed with Cauda Equina Syndrome who underwent operation in Al-Zahra Hospital of Isfahan from 2013 to 2015 were followed up for two years and the effect of the surgery on the improvement of their clinical symptoms was investigated. Results: In this study, 33 patients with Cauda Equina Syndrome were evaluated. About 24-month follow-up of patients showed muscle weakness improvement in 26(78.8%) of them. Of all 19 patients with urinary dysfunction, 18(94.7%) recovered. Six (33.3%) cases improved the day after surgery, 6(33.3%) cases in one month, 4(22.2%) cases in six months, and 2(11.1%) cases within 24 months after the surgery. All 4(100%) patients with bowl disorder also recovered during the study. One (25%) of them improved the day after operation, 1(25%) one month after the operation and 2(50%) within 24 months following the operation. Conclusion: According to the results of this study, operation of the lumbar disks leads to improvement of Cauda Equina Syndrome, including recovery of sphincter disorders and muscle weakness, but considering the limitations of our investigation (including a small sample size), further studies are recommended in this area.
