Abstract
Introduction Postoperative urinary retention (POUR) is the inability to urinate after a surgical procedure despite having a full bladder. It is a common complication following lumbar spine surgery which has been extensively linked to increased patient morbidity and hospital costs. This study hopes to development and validate a predictive model for POUR following lumbar spine surgery using patient demographics, surgical and anesthesia variables. Methods This is a retrospective observational cohort study of 903 patients who underwent lumbar spine surgery over the period of June 2017 to June 2019 in a tertiary academic medical center. Four hundred and nineteen variables were collected including patient demographics, ICD-10 codes, and intraoperative factors. Least absolute shrinkage and selection operation (LASSO) regression and logistic regression models were compared. A decision tree model was fitted to the optimal model to classify each patient's risk of developing POUR as high, intermediate, or low risk. Predictive performance of POUR was assessed by area under the receiver operating characteristic curve (AUC-ROC). Results 903 patients were included with average age 60 ± 15 years, body mass index of 30.5 ± 6.4 kg/m2, 476 (53%) male, 785 (87%) white, 446 (49%) involving fusions, with average 2.1 ± 2.0 levels. The incidence of POUR was 235 (26%) with 63 (7%) requiring indwelling catheter placement. A decision tree was constructed with an accuracy of 87.8%. Conclusion We present a highly accurate and easy to implement decision tree model which predicts POUR following lumbar spine surgery using preoperative and intraoperative variables.

Development and Validation of Machine Learning-Based Predictive Model for Prolonged Hospital Stay after Decompression Surgery for Lumbar Spinal Canal Stenosis. Spine Surg Relat Res 2024; 8:315-321. [PMID: 38868786 PMCID: PMC11165502 DOI: 10.22603/ssrr.2023-0255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Accepted: 11/25/2023] [Indexed: 06/14/2024] Open
Abstract
Introduction Precise prediction of hospital stay duration is essential for maximizing resource utilization during surgery. Existing lumbar spinal stenosis (LSS) surgery prediction models lack accuracy and generalizability. Machine learning can improve accuracy by considering preoperative factors. This study aimed to develop and validate a machine learning-based model for estimating hospital stay duration following decompression surgery for LSS. Methods Data from 848 patients who underwent decompression surgery for LSS at three hospitals were examined. Twelve prediction models, using 79 preoperative variables, were developed for postoperative hospital stay estimation. The top five models were chosen. Fourteen models predicted prolonged hospital stay (≥14 days), and the most accurate model was chosen. Models were validated using a randomly divided training sample (70%) and testing cohort (30%). Results The top five models showed moderate linear correlations (0.576-0.624) between predicted and measured values in the testing sample. The ensemble of these models had moderate prediction accuracy for final length of stay (linear correlation 0.626, absolute mean error 2.26 days, standard deviation 3.45 days). The c5.0 decision tree model was the top predictor for prolonged hospital stay, with accuracies of 89.63% (training) and 87.2% (testing). Key predictors for longer stay included JOABPEQ social life domain, facility, history of vertebral fracture, diagnosis, and Visual Analogue Scale (VAS) of low back pain. Conclusions A machine learning-based model was developed to predict postoperative hospital stay after LSS decompression surgery, using data from multiple hospital settings. Numerical prediction of length of stay was not very accurate, although favorable prediction of prolonged stay was accomplished using preoperative factors. The JOABPEQ social life domain score was the most important predictor.

Abstract
Placement of penile prosthesis had been well described in the outpatient setting, however, one barrier to same-day discharge is postoperative urinary retention (POUR). POUR remains a condition encountered during ambulatory surgical procedures and has yet to be characterized in patients undergoing penile prosthesis. We characterized POUR in a cohort of penile prosthesis recipients along with risk factors and management. Patients undergoing penile prosthesis implantation from 2014 through 2020 without pre-existing retention were included. All patients underwent a void trial immediately following penile prosthesis in the post-anesthesia care unit. POUR was strictly defined as (1) any patient requiring catheter replacement after prosthesis, (2) a rising post-void residual, or (3) inability to void after 6 h regardless of whether a catheter was placed. Independent procedures, demographic, intraoperative, and postoperative risk factors for POUR were assessed. 317 men were included of whom 27.1% experienced POUR. Men experiencing POUR and those not in retention were essentially indistinguishable with respect to previously described risk factors for POUR. Only use of both α-blockers and 5-α-reductase inhibitors was significantly associated with a greater risk of POUR, a finding maintained on adjusted analysis (adjusted odds ratio 10.1, 95% confidence interval 2.1 to 49.8). POUR resolved without intervention in 3.5%, a single episode of clean intermittent catheterization (CIC) in 7.0% of patients, and repeated CIC or indwelling catheter placement with a successful delayed void trial in 88.4% of patients. Rate of prosthesis infection in patients who experienced POUR did not significantly differ from those who did not experience POUR (4.7% vs. 2.2% p = 0.26). Our findings suggest that POUR is experienced in as many as 1 in 4 men undergoing penile prosthesis placement, most of whom must be managed with indwelling catheterization or repeated CIC. Those with indicators of symptomatic prostate enlargement are at significantly greater risk of urinary retention.

Abstract
BACKGROUND Postoperative urine retention (POUR) after lumbar interbody fusion surgery may lead to recatheterization and prolonged hospitalization. In this study, a predictive model was constructed and validated. The objective was to provide a nomogram for estimating the risk of POUR and then reducing the incidence. METHODS A total of 423 cases of lumbar fusion surgery were included; 65 of these cases developed POUR, an incidence of 15.4%. The dataset is divided into a training set and a validation set according to time. 18 candidate variables were selected. The candidate variables were screened through LASSO regression. The stepwise regression and random forest analysis were then conducted to construct the predictive model and draw a nomogram. The area under the curve (AUC) of the receiver operating characteristic (ROC) curve and the calibration curve were used to evaluate the predictive effect of the model. RESULTS The best lambda value in LASSO was 0.025082; according to this, five significant variables were screened, including age, smoking history, surgical method, operative time, and visual analog scale (VAS) score of postoperative low back pain. A predictive model containing four variables was constructed by stepwise regression. The variables included age (β = 0.047, OR = 1.048), smoking history (β = 1.950, OR = 7.031), operative time (β = 0.022, OR = 1.022), and postoperative VAS score of low back pain (β = 2.554, OR = 12.858). A nomogram was drawn based on the results. The AUC of the ROC curve of the training set was 0.891, the validation set was 0.854 in the stepwise regression model. The calibration curves of the training set and validation set are in good agreement with the actual curves, showing that the stepwise regression model has good prediction ability. The AUC of the training set was 0.996, and that of the verification set was 0.856 in the random forest model. CONCLUSION This study developed and internally validated a new nomogram and a random forest model for predicting the risk of POUR after lumbar interbody fusion surgery. Both of the nomogram and the random forest model have high accuracy in this study.

Abstract
BACKGROUND AND OBJECTIVES Postoperative urinary retention (POUR) is associated with significant morbidity. Our institution's POUR rate was elevated among patients undergoing elective lumbar spinal surgery. We sought to demonstrate that our quality improvement (QI) intervention would significantly lower our POUR rate and length of stay (LOS). METHODS A resident-led QI intervention was implemented from October 2017 to 2018 on 422 patients in an academically affiliated community teaching hospital. This consisted of standardized intraoperative indwelling catheter utilization, postoperative catheterization protocol, prophylactic tamsulosin, and early ambulation after surgery. Baseline data on 277 patients were collected retrospectively from October 2015 to September 2016. Primary outcomes were POUR and LOS. The focus, analyze, develop, execute, and evaluate (FADE) model was used. Multivariable analyses were used. P value <.05 was considered significant. RESULTS We analyzed 699 patients (277 pre-intervention vs 422 post-intervention). The POUR rate (6.9% vs 2.6%, Δ confidence interval [CI] 1.15-8.08, P = .007) and mean LOS (2.94 ± 1.87 days vs 2.56 ± 2.2 days, Δ CI 0.066-0.68, P = .017) were significantly improved following our intervention. Logistic regression demonstrated that the intervention was independently associated with significantly decreased odds for developing POUR (odds ratio [OR] = 0.38, CI 0.17-0.83, P = .015). Diabetes (OR = 2.25, CI 1.03-4.92, P = .04) and longer surgery duration (OR = 1.006, CI 1.002-1.01, P = .002) were independently associated with increased odds of developing POUR. CONCLUSIONS After implementing our POUR QI project for patients undergoing elective lumbar spine surgery, the institutional POUR rate significantly decreased by 4.3% (62% reduction) and LOS, by 0.37 days. We demonstrated that a standardized POUR care bundle was independently associated with a significant decrease in the odds of developing POUR.

Abstract
The authors outline a review of preoperative, intraoperative, and postoperative considerations surrounding adult spinal deformity. Preoperative management topics include imaging, hemoglobin A1c levels before spine surgery, osteoporotic management, and prehabilitation. Topics surrounding intraoperative management include the use of antibiotics, liposomal bupivacaine, and Foley catheters. The authors also discuss postoperative questions surrounding analgesia, nausea and vomiting, thromboembolic prophylaxis, and early mobilization. Throughout their discussion, the authors incorporate enhanced recovery after surgery protocols to hopefully lead to future discussions regarding optimizing complex spinal patients.

Abstract
Objective: The present systematic review and meta-analysis aimed to estimate the prophylactic effect of alpha blockers against postoperative urinary retention (POUR) in orthopaedic patients. Methods: PubMed, Embase, Web of Science and Cochrane Library databases were searched between 1 January 1990 and 1 March 2023. The studies reporting the preventive efficacy of alpha blockers on POUR after orthopaedic procedures were identified. The pooled rates of POUR in the Intervention group (patients receiving alpha blockers) and the Control group (patients not receiving alpha blockers) were estimated and compared. The risk ratios (RRs) were calculated using the random-effects model. Subgroup analysis was performed based on surgical type. Trial sequential analysis (TSA) was conducted to confirm the robustness of pooled results. Results: Seven studies containing 1,607 patients were identified. The rates of POUR were similar between the two groups (Intervention group: 126/748 [16.8%] VS. Control group: 168/859 [19.6%]; RR = 0.75; 95% confidence interval [CI] 0.51 to 1.09; p = 0.130; Heterogeneity: I2 = 67.1%; p = 0.006). No significant difference in the incidence of POUR was observed in either the Arthroplasty subgroup or Spine surgery subgroup. The result of TSA suggested that the total sample size of the existing evidence might be insufficient to draw conclusive results. Administrating alpha blockers was associated with a higher risk of complications (88/651 [13.5%] VS. 56/766 [7.3%]; RR = 1.73; 95% CI 1.27 to 2.37; p = 0.0005; Heterogeneity: I2 = 0%; p = 0.69). Conclusion: Prophylactic alpha blockers do not reduce the risk of POUR in orthopaedic procedures, and administrating these drugs was associated with a higher risk of complications.

Abstract
STUDY DESIGN Systematic Review and Meta-analysis. OBJECTIVE Postoperative urinary retention (POUR) is a common complication following lumbar spine surgery (LSS) and timely recognition is imperative to avoid long-term consequences. The aim of the current meta-analysis was to systematically review the literature in order to identify risk factors associated with POUR after LSS. METHODS In accordance with PRISMA guidelines, a systematic review of the literature was performed using Pubmed, EMBASE, and MEDLINE database for articles on POUR following LSS. A meta-analysis was performed comparing patients with and without POUR; and the factors associated with this adverse event were analyzed. The pooled data were reported as mean differences with 95% confidence intervals (CI; P < .05). Heterogeneity among the studies was evaluated using the I2 statistic. RESULTS The meta-analysis included 10 studies compromised of 30,300 patients. Based on our analysis, patients who were male, were older in age, underwent instrumented fusion, had diabetes mellitus, coronary artery disease, or benign prostatic hypertrophy had significantly higher risk of developing POUR. Additionally, patients in who developed POUR had significantly longer surgical times and higher volumes of intra-operative fluid administration, as compared with non-POUR patients. The POUR patients also had a significantly higher association with urinary tract infection. Prior surgery, BMI, length of stay, and smoking status did not reveal any statistical association with POUR. CONCLUSIONS Risk factors associated with POUR following LSS include male gender, older age, longer surgical times, fusion procedures, larger volumes of intraoperative infusions, and associated comorbidities like DM, CAD, and BPH.

Retrospective analysis of drug resistance characteristics and infection related risk factors of multidrug-resistant organisms (MDROs) isolated from the orthopedics department of a tertiary hospital. Sci Rep 2023; 13:2199.

Abstract
Patients infected with multidrug-resistant organisms (MDROs) are known to exhibit longer hospital stays and a significantly poorer prognosis. We performed a 6-year retrospective analysis of nosocomial infections reported in the orthopedics department of our institution, to gain valuable insights into antibiotic sensitivity and infectious characteristics of MDROs, in order to deduce effective measures to control the occurrence of multidrug-resistant infections in clinical practice. A retrospective, single center surveillance study (January 2012-December 2017) was performed on the nosocomial infections recorded in the department of orthopedics. A nosocomial infection is defined as one that develops when a patient is residing in a hospital but was not present at the time of admission. All relevant data, including basic patient information, cultivated bacterial strains, and antimicrobial resistance, was obtained from the hospital information system. A total of 1392 strains of pathogenic bacteria were isolated; 358 belonged to MDROs (detection rate = 25.7%). All the isolated strains of MDROs were mostly from secretions (52.2%). The number of cases infected with MDROs were 144 (40.2%) and 129 (36.0%) in the trauma and spinal wards, respectively. MRSA showed high resistance to β lactam antibiotics, but was sensitive to quinolone antibiotics, linezolid and cotrimoxazole. ESBL-positive strains showed more sensitivity to carbapenem antibiotics (resistance rate < 10%). MDR nonfermenters showed high resistance to most antibiotics. Logistic multivariate analysis revealed age, open injury, and central nervous system injury as independent risk factors for multidrug resistant infections. A high antibiotic resistance rate and an increasing prevalence of infections with MDROs was identified in the orthopedics department. Patients with open injury, central nervous system injury and those aged ≥ 60 years, were more prone to multidrug-resistant infections. Clinicians should pay more attention to such patients in order to actively prevent and control the occurrence of infections caused by MDROs.

Abstract
OBJECTIVE To assess the utility of intraoperative bulbocavernosus reflex (BCR) monitoring in posterior lumbar fusion surgery. METHODS We retrospectively evaluated 153 patients undergoing posterior lumbar fusion with intraoperative BCR monitoring. Voiding function was assessed at discharge and two follow-ups. RESULTS BCR was preserved in 151 patients and completely disappeared in two patients at the end of surgery. For patients in whom BCR was preserved, voiding difficulties at discharge and 1-month and 6-month follow-ups were noted in 16 (10.6%), 9 (6.0%), and 0 (0.0%) patients, respectively. However, patients with BCR loss experienced voiding difficulties at all three time-points. Statistical analysis showed a significant difference in voiding between those with preserved and disappeared BCRs at 6 months postoperatively. BCR disappeared during surgery but recovered before the end of surgery in six patients. Among these patients, one experienced transient voiding difficulties postoperatively but with good recovery. However, the other five patients did not experience postoperative voiding difficulties. CONCLUSIONS BCR had low sensitivity for voiding dysfunction at discharge, but had high accuracy at 6-month follow-up examinations. BCR loss was associated with new voiding dysfunction. SIGNIFICANCE Intraoperative BCR monitoring is a potentially useful tool for enhancing safety during posterior lumbar fusion by predicting postoperative voiding dysfunction.

Abstract
OBJECTIVE The authors' objective was to determine whether preoperative administration of tamsulosin decreases postoperative urinary retention after spine surgery. METHODS In this randomized, double-blind, placebo-controlled clinical trial performed at a single institution between 2016 and 2019, eligible males aged 50 to 85 years were administered tamsulosin or placebo for 5 days prior to elective spine surgery. Patients were excluded if they were taking alpha adrenergic blocking drugs; were allergic to tamsulosin, lactose, or sulfa drugs; had a preexisting indwelling urinary catheter, orthostatic hypotension, history of urological surgery, or renal failure; or were scheduled for cataract surgery within 2 weeks. Screening identified 1051 eligible patients (140 declined participation, 150 did not meet the inclusion criteria, and 151 did not enroll for other reasons). A total of 610 patients were randomly assigned to receive 0.4 mg oral tamsulosin or an identical placebo capsule for 5 days preoperatively and 2 days postoperatively. RESULTS A total of 497 patients were included in the final statistical analysis. The overall rate of postoperative urinary retention was 9.7%, and tamsulosin had no observed effect on reducing the rate of postoperative urinary retention as compared with placebo (9.4% vs 9.9%, p = 0.96). There were no significant differences in the reported adverse events between groups. Multivariate logistic regression was performed to model the effects of patient, surgical, and anesthetic factors on postoperative urinary retention, and the study drug remained an insignificant factor. CONCLUSIONS This study did not detect an effect of perioperative tamsulosin on reducing the rate of postoperative urinary retention in male patients aged 50 to 85 years who underwent elective spine surgery. This study does not support the routine use of tamsulosin to reduce postoperative urinary retention in patients without a previous prescription. It is unknown if subpopulations exist for which prophylactic tamsulosin may reduce postoperative urinary retention.

Abstract
OBJECTIVE Postoperative urinary retention (POUR) is a common complication after spine surgery and is associated with prolongation of hospital stay, increased hospital cost, increased rate of urinary tract infection, bladder overdistention, and autonomic dysregulation. POUR incidence following spine surgery ranges between 5.6% and 38%; no reliable prediction tool to identify those at higher risk is available, and that constitutes an important gap in the literature. The objective of this study was to develop and validate a preoperative risk model to predict the occurrence of POUR following routine elective spine surgery. METHODS The authors conducted a retrospective chart review of consecutive adults who underwent lumbar spine surgery between June 1, 2017, and June 1, 2019. Patient characteristics, preexisting ICD-10 codes, preoperative pain and opioid use, preoperative alpha-1 blocker use, details of surgical planning, development of POUR, and management strategies were abstracted from electronic medical records. A binomial logistic model and a multilayer perceptron (MLP) were optimized using training and validation sets. The models' performance was then evaluated on model-naïve patients (not a part of either cohort). The models were then stacked to take advantage of each model's strengths and to avoid their weaknesses. Four additional models were developed from previously published models adjusted to include only relevant factors (i.e., factors known preoperatively and applied to the lumbar spine). RESULTS Overall, 891 patients were included in the cohort, with a mean of 59.6 ± 15.5 years of age, 52.7% male, BMI 30.4 ± 6.4, American Society of Anesthesiologists class 2.8 ± 0.6, and a mean of 5.6 ± 5.7 comorbidities. The rate of POUR was found to be 25.9%. The two models were comparable, with an area under the curve (AUC) of 0.737 for the regression model and 0.735 for the neural network. By combining the two models, an AUC of 0.753 was achieved. With a regression model probability cutoff of 0.24 and a neural network cutoff of 0.23, maximal sensitivity and specificity were achieved, with specificity 68.2%, sensitivity 72.9%, negative predictive value 88.2%, and positive predictive value 43.4%. Both models individually outperformed previously published models (AUC 0.516-0.645) when applied to the current data set. CONCLUSIONS This predictive model can be a powerful preoperative tool in predicting patients who will be likely to develop POUR. By using a combination of regression and neural network modeling, good sensitivity, specificity, and NPV are achieved.

Abstract
Objective Postoperative urinary retention (POUR) is an often-underestimated common complication following spine surgery, and it is essential to avoid its untoward long-term consequences. Besides, a dilemma exists regarding the appropriate timing for the postoperative removal of indwelling catheter (IDC). Hence, we aim to describe the prevalence, risk factors, and outcomes of POUR and also come up with recommendations for the removal of IDC. Methods Electronic records of patients who underwent elective thoracolumbosacral spinal fusion surgery from January 2017 to December 2019 were retrospectively reviewed. Excluded were those who underwent fusion for indications such as trauma, cauda equina syndrome, infection, and malignancy. Both surgery-related and patient-related risk factors were tabulated, and their association with the likely development of POUR was assessed by univariate and multivariate analysis. Results One hundred sixty-eight patients (median age=64.1 years; 58.9% female) were included, with the incidence of POUR being 7.8%. Our findings suggest surgery-related factors, both intra- and postoperative, including operating time (p=0.008), anesthetic time (p=0.005), number of fusion levels (p<0.001), mobilization status prior to trial off catheter (TOC; p=0.021), and TOC timing (p=0.029) may have an association with POUR. In addition, patient-related factors, including the use of beta-blockers (p=0.020) and pre-operative mobility status (p<0.001), may also be associated with the likely development of POUR. Conclusion POUR seems to be a frequent complication following thoracolumbosacral spinal fusion surgery, which was found to have an association with some surgery-related and patient-related factors. While most of these factors are non-modifiable, certain modifiable risk factors provide the surgeon an opportunity to prevent POUR. Considering these factors, we recommend appropriate and timely mobilization of the patient prior to removal of IDC, which is to be performed preferably in the daytime.

Risk factors for postoperative urinary retention following elective spine surgery: a meta-analysis. Spine J 2021; 21:1802-1811. [PMID: 34015508 DOI: 10.1016/j.spinee.2021.05.009] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Revised: 04/18/2021] [Accepted: 05/07/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Limited studies have investigated risk factors for postoperative urinary retention (POUR) following elective spine surgery. Furthermore, some discrepancies have been found in the results of existing observational studies. PURPOSE This study aimed to review the available literature on risk factors associated with POUR following elective spine surgery. STUDY DESIGN A systematic review with meta-analysis was performed. PATIENT SAMPLE A total of 31,251 patients (POUR=2,858, no POUR=28,393) were included in the meta-analysis. OUTCOME MEASURES Demographics, type of elective spine surgery, country, definition of POUR, and potential risk factors for POUR were evaluated. METHODS The Cochrane Library, Embase, and Medline electronic databases were searched to identify relevant studies. Binary outcomes were reported as odds ratio (OR). Weighted mean differences (WMD) or standardized mean differences (SMD), with 95% confidence intervals (CI), were used for meta-analysis of continuous outcomes. RESULTS Eleven studies (2 prospective and 9 retrospective) were included in the analysis. Patients with POUR were older than those without POUR (WMD, 7.13; 95% CI, 4.50-9.76). Male patients were found to have an increased risk of POUR (OR, 1.31; 95% CI, 1.04-1.64). The following variables were also identified as significant risk factors for POUR: benign prostatic hyperplasia (BPH; OR, 3.79; 95% CI, 1.89-7.62), diabetes mellitus (DM; OR, 1.50; 95% CI, 1.17-1.93), and previous urinary tract infection (UTI; OR, 1.70; 95% CI, 1.28-2.24). Moreover, longer operative time (WMD, 19.88; 95% CI, 5.01-34.75) and increased intraoperative fluid support (SMD, 0.37; 95% CI, 0.23-0.52) were observed in patients with POUR. In contrast, spine surgical procedures involving fewer levels (OR, 0.75; 95% CI, 0.65-0.86), and ambulation on the same day as surgery (OR, 0.65; 95% CI, 0.52-0.81) were associated with a decreased risk of POUR. CONCLUSIONS Based on our meta-analysis, older age, male gender, BPH, DM, and a history of UTI are risk factors for POUR following elective spine surgery. We also found that longer operative time and increased intravenous fluid support would increase the risk of POUR. Additionally, multi-level spine surgery may have a negative effect on postoperative voiding.

Sacrectomy for sacral tumors: perioperative outcomes in a large-volume comprehensive cancer center. Spine J 2021; 21:1908-1919.

Abstract
BACKGROUND CONTEXT Sacral tumors are incredibly rare lesions affecting fewer than one in every 10,000 persons. Reported perioperative morbidity rates range widely, varying from 30% to 70%, due to the relatively low volumes seen by most centers. Factors affecting perioperative outcome following sacrectomy remain ill-defined. PURPOSE To characterize perioperative outcomes of sacral tumor patients undergoing sacrectomy and identify independent risk factors of perioperative morbidity STUDY DESIGN/SETTING: Retrospective cohort study at a single comprehensive cancer center PATIENT SAMPLE: Consecutively treated sacral tumor patients (primary or metastatic) undergoing sacrectomy for oncologic resection between April 2013 and April 2020 OUTCOME MEASURES: Perioperative complications, hospital length of stay, non-home discharge, 30-day readmission, and 30-day reoperation METHODS: Details were gathered about tumor pathology and morphology, surgery performed, baseline medical comorbidities, preoperative lab data, and patient demographics. Stepwise multivariable regressions were conducted to identify independent risk factors of perioperative outcomes while evaluating predictive accuracy. RESULTS 57 sacral tumor patients were included (mean age 55.5±13.0 years; 60% female). The complication, non-home discharge, 30-day readmission, and 30-day reoperation rates were 39%, 56%, 16%, and 14%, respectively. Independent predictors of perioperative complications included ASA>2 (OR=10.7; 95%CI [1.3, 86.0]; p=0.026), radicular pain (OR=10.9; p=0.014), platelet count (OR=0.989 per 10³/μL; p=0.049), and instrumentation (OR=10.7; p=0.009). Independent predictors of length of stay included iliac vessel involvement (β=15.8; p=0.005), larger tumor volume (β=0.027 per cm³; p<0.001), a staged procedure (β=10.0; p=0.018), and S1 nerve root sacrifice (OR=15.8; p=.011). The optimal model predictive of non-home discharge included bilateral S3-S5 or higher nerve root sacrifice (OR=3.9; p=0.054), instrumentation (OR=8.6; p=0.005), and vertical rectus abdominis musculocutaneous flap closure (OR=5.3; p=0.067). 30-day readmission was independently predicted by history of chronic kidney disease (OR=26.7; p=0.021), radicular pain (OR=8.1; p=0.039), and preoperative saddle anesthesia (OR=12.6; p=0.026). All multivariable models achieved good discrimination (AUC>0.8 and R2>0.7). CONCLUSION Clinical and operative factors were important predictors of complications and 30-day readmission, while tumor-related and operative factors accounted for most of the variability in length of stay and non-home discharge.

Abstract
Background Urinary catheters (UC) are used by some surgeons during total joint arthroplasty (TJA). This study investigated the impact of intraoperative urinary catheters on postoperative urinary retention (POUR) following TJA cases. Methods We conducted a retrospective comparative study across 11 medical centers on 9,580 TJA patients. Visits to urgent care or the emergency department within 7 and 30 postoperative days were reviewed. Medical records over a 12-month period for all patients older than 18 years old were used to gather demographic and surgical data as well as the incidence of urinary tract infection (UTI). Chi-squared tests (RStudio) were used to determine statistical significance against P-Values (P) < 0.05. Results 13 (0.14%) patients returned within 7 days for POUR. POUR was more common in males [10 (0.3%) vs. 3 (0.1%) females, (P = 0.01)]. There was no difference in POUR when comparing total hip and knee arthroplasty procedures [0.16% vs. 0.12%, (P = 0.60)]. Of all operations, 25% had intraoperative UC use. There was no difference in POUR between the UC and no UC groups [0.21 vs. 0.11%, (P = 0.26)]. However, there was an increase in UTI in UC vs. no UC use within 7 postoperative days [0.92 vs. 0.43%, (P = 0.005)] and 30 postoperative days [2.60 vs. 1.50 %, (P < 0.001)]. Conclusion In our study, there was no difference in POUR rates between the intraoperative UC vs. no UC groups. Therefore, the use of intraoperative UC may not decrease the rate of POUR following TJA procedures. Additionally, UTI risk was higher in the UC group which may be attributable to other factors, especially when comparing female vs. male patients.

Abstract
BACKGROUND Lower urinary tract dysfunction is common in the early postoperative phase after spine surgery. Although it is essential for an optimal patient management to balance benefits and harms, it is not known which patient benefit from a perioperative indwelling catheter. We therefore evaluated urological parameters prior and after spine surgery performing a quality assessment of our current clinical practice in bladder management. METHODS Preoperatively, all patients completed the International Prostate Symptom Score and were interviewed for urological history. Decision for preoperative urethral catheter placement was individually made by the responsible anesthesiologist according to an in-house protocol. Within and between group analyses using univariate and probability matching statistics were performed for patients with intraoperative urethral catheter-free management (n = 54) and those with a preoperatively placed catheter (n = 46). Post void residual (PVR) was measured prior and after surgery or after removal of the urethral catheter, respectively. The outcome measures consisted of postoperative urinary retention (POUR) and postoperative urological complications (PUC), defined as POUR and any catheter-related adverse events. RESULTS Hundred patients undergoing spine surgery were prospectively evaluated. Sixteen of the 54 (30%) patients with urethral catheter-free management developed POUR. Length of surgery and volume of intravenous infusion were associated with POUR (p < 0.05). In the 46 preoperatively catheterized patients, re-catheterization was required in 6 (13%). In a fairly homogenous subgroup of 72 patients with a probability of PUC between 15 and 40%, no significant association between intraoperative urethral catheter-free management and the occurrence of PUC was found (odds ratio 2.09, 95% confidence interval 0.69 to 6.33; p = 0.193). CONCLUSIONS In case of postoperative PVR monitoring allowing de novo catheterization as appropriate, urethral catheter-free management seems to be a valuable option in spine surgery since it does not to increase PUC but minimizes unnecessary catheterizations with their related complications.

Abstract
Background Enhanced recovery in spinal surgery (ERSS) has shown promising improvements in clinical and economical outcomes. We have proposed an ERSS pathway based on available evidence. We aimed to delineate the clinical efficacy of individual pathway components in ERSS through a systematic narrative review. Methods We included systematic reviews and meta-analysis, randomized controlled trials, non-randomized controlled studies, and observational studies in adults and pediatric patients evaluating any one of the 22 pre-defined components. Our primary outcomes included all-cause mortality, morbidity outcomes (e.g., pulmonary, cardiac, renal, surgical complications), patient-reported outcomes and experiences (e.g., pain, quality of care experience), and health services outcomes (e.g., length of stay and costs). Following databases (1990 onwards) were searched: MEDLINE, EMBASE, and Cochrane Library (Cochrane Database of Systematic Reviews and CENTRAL). Two authors screened the citations, full-text articles, and extracted data. A narrative synthesis was provided. We constructed Evidence Profile (EP) tables for each component of the pathway, where appropriate information was available. Due to clinical and methodological heterogeneity, we did not conduct a meta-analyses. GRADE system was used to classify confidence in cumulative evidence for each component of the pathway. Results We identified 5423 relevant studies excluding duplicates as relating to the 22 pre-defined components of enhanced recovery in spinal surgery. We included 664 studies in the systematic review. We identified specific evidence within the context of spinal surgery for 14/22 proposed components. Evidence was summarized in EP tables where suitable. We performed thematic synthesis without EP for 6/22 elements. We identified appropriate societal guidelines for the remainder of the components. Conclusions We identified the following components with high quality of evidence as per GRADE system: pre-emptive analgesia, peri-operative blood conservation (antifibrinolytic use), surgical site preparation and antibiotic prophylaxis. There was moderate level of evidence for implementation of prehabilitation, minimally invasive surgery, multimodal perioperative analgesia, intravenous lignocaine and ketamine use as well as early mobilization. This review allows for the first formalized evidence-based unified protocol in the field of ERSS. Further studies validating the multimodal ERSS framework are essential to guide the future evolution of care in patients undergoing spinal surgery.

Abstract
STUDY DESIGN The study is designed as a retrospective cohort study. OBJECTIVE The aim of this study was to identify modifiable and nonmodifiable risk factors of postoperative urinary retention in spine surgery patients. SUMMARY OF BACKGROUND DATA Postoperative urinary retention is a common complication in patients undergoing operative procedures requiring anesthesia. Current studies have shown significant risk factors for postoperative urinary retention, but most are nonmodifiable and subsequently of limited usefulness in preventing this complication. Several new studies have shown possible modifiable risk factors, but current data are inconsistent in terms of their statistical significance. METHODS A total of 814 consecutive patients who underwent open posterior lumbar laminectomy and fusion were included in the retrospective cohort study. Pre, intra-, and postoperative characteristics were collected in all patients to identify risk factors for postoperative urinary retention. RESULTS Glycopyrrolate use (odds ratio [OR] 2.60; P = 0.001), decreased body mass index (OR 0.96; P = 0.018), previous diagnosis of benign prostate hyperplasia (OR 3.34; P ≤ 0.001), and postoperative urinary tract infection (OR 5.60, P = 0.005) were associated with postoperative urinary retention. Previous history of lumbar spine surgery (OR 0.55; P = 0.019) was associated with decreased rates of postoperative urinary retention. CONCLUSION Glycopyrrolate use, benign prostate hyperplasia, and postoperative urinary tract infection were independent risk factors for postoperative urinary retention. The use of glycopyrrolate is a potentially modifiable risk factor for postoperative urinary retention.Level of Evidence: 3.

Abstract
Objective: Postoperative urinary retention is a common complication for patients recovering from general anesthesia or invasive surgery near the spinal column. However, no study has systematically reviewed the incidence of postoperative urinary retention for spinal surgeries performed at the cervical, thoracic, or lumbar spinal regions. In this review, we critically analyze and summarize the known literature on the incidence and risk factors associated with postoperative urinary retention after spinal surgery. Methods: A comprehensive literature review was performed at the end of September 2019 within the PubMed database. Results: The average incidence of postoperative urinary retention from nine of the 10 studies was 17.2% with one paper that did not report on postoperative urinary retention incidence. Furthermore, age, male gender, location and history of spinal surgery, duration of surgery, benign prostatic hypertrophy, and Foley catheter were reported as major risk factors for postoperative urinary retention and spinal surgery. Conclusion: Overall, spinal cord and postoperative urinary retention remains a poorly understood area requiring further investigation into the incidence, risk factors, and surgical methods influence postoperative urinary retention and post-operative outcomes. We believe an overview of such data can help revise guidelines for the management of postoperative urinary retention and raise awareness of its prevalence in elderly patients undergoing spinal surgery. Level of evidence: Not applicable for this multicentre audit.

Chronic opioid use is associated with increased postoperative urinary retention, length of stay and non-routine discharge following lumbar fusion surgery. Clin Neurol Neurosurg 2020; 197:106161. [PMID: 32854090 DOI: 10.1016/j.clineuro.2020.106161] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Revised: 08/13/2020] [Accepted: 08/16/2020] [Indexed: 12/01/2022]
Abstract
BACKGROUND The incidence of chronic opioid use (COU) is increasing with health related complications impacting both patients and healthcare services. OBJECTIVE The aim of this study was to identify the impact of COU on postoperative urinary retention (PUR) in patients following lumbar fusion surgery as well as its impact on length of stay (LOS) and non-routine discharges (NRD). MATERIALS & METHODS The State Inpatient Databases were utilised to identify patients undergoing elective lumbar fusion procedures. Patients with and without COU were separated into groups and matched using 3:1 propensity score matching. PUR, LOS in the upper quartile and discharge to a location other than home were the outcomes of interest. Multivariable logistic regression was used to examine the impact of COU on the above outcomes and Wald chi-square tests were used to determine the factors with the most significant associations. RESULTS COU was significant for PUR (p = 0.037), prolonged LOS (p < 0.001), and NRD (p < 0.001). Factors most significantly associated with PUR were Elixhauser Mortality Index and COU both with p < 0.05. Factors associated with prolonged LOS and NRD were Elixhauser Mortality Index, COU, and insurance status. CONCLUSION COU has a notable impact on PUR, LOS, and NRD. The Elixhauser Mortality Index and insurance status of patients also showed predictive utility for these outcomes. This knowledge enables us to identify sources of pressure for health services and approach them strategically through increased awareness.

Abstract
Fluid management has been widely recognized as an important component of the perioperative care in patients undergoing major procedures including spine surgeries. Patient- and surgery-related factors such as age, length of the surgery, massive intraoperative blood loss, and prone positioning, may impact the intraoperative administration of fluids. In addition, the type of fluid administered may also affect post-operative outcomes. Published literature describing intraoperative fluid management in patients undergoing major spine surgeries is limited and remains controversial. Therefore, we reviewed current literature on intraoperative fluid management and its association with post-operative complications in spine surgery.

Cauda Equina Syndrome: A Review of 15 Patients Who Underwent Percutaneous Transforaminal Endoscopic Lumbar Discectomy (PTELD) Under Local Anaesthesia. Malays Orthop J 2020; 14:101-110. [PMID: 32983384 PMCID: PMC7513651 DOI: 10.5704/moj.2007.019] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2019] [Accepted: 04/19/2020] [Indexed: 02/05/2023] Open
Abstract
INTRODUCTION To analyse the results of Cauda Equina Syndrome (CES) operated by Percutaneous Transforaminal Endoscopic Lumbar Discectomy (PTELD). MATERIAL AND METHODS The study is a retrospective series of 15 patients operated by PTELD. Bladder dysfunction was classified as incomplete CES (CESI) and complete CES retention (CESR). Bladder / motor recovery rate and its timing, Oswestry Disability Index (ODI), Visual Analogue Score (VAS), patient satisfaction index, and sexual dysfunction were used to measure the outcome objectively. Additionally, in CESR patients, post-void residual (PVR) urine was measured by sonography. Complications and technical problems were noted. RESULTS There were ten patients of CESI and five patients of CESR. The average follow-up was 20.33(12.05) months. Bladder symptoms recovery was 100%, and motor recovery was 80%. VAS for back pain recovered to 0.53(0.52) from 8(2.39). VAS for leg pain recovered to 0.13(0.35) from 9.20(1.32). ODI improved to 6.07(2.85) from 77.52(13.20). The time to the recovery of bladder function was 1.47(1.55) days. All CESR patient's abnormal PVR urine was normalised at five weeks post-operative. No complications were reported. However, five technical executional problems occurred. CONCLUSION PTELD can be considered for CES treatment due to its substantial and quick recovery advantages. However, more evidence support is needed to make it a practice recommendation.
