[PMID: 36651058 DOI: 10.1080/1040841x.2023.2167593] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Revised: 11/01/2022] [Accepted: 01/09/2023] [Indexed: 01/19/2023]
Abstract
Present-day healthcare employs several types of invasive devices, including urinary catheters, to improve medical wellness, the clinical outcome of disease, and the quality of patient life. Among urinary catheters, the Foley catheter is most commonly used in patients for bladder drainage and collection of urine. Although such devices are very useful for patients who cannot empty their bladder for various reasons, they also expose patients to catheter-associated urinary tract infections (CAUTIs). Catheter provides an ideal surface for bacterial colonization and biofilm formation, resulting in persistent bacterial infection and severe complications. Hence, rigorous efforts have been made to develop catheters that harbour antimicrobial and anti-fouling properties to resist colonization by bacterial pathogens. In this regard, catheter modification by surface functionalization, impregnation, blending, or coating with antibiotics, bioactive compounds, and nanoformulations have proved to be effective in controlling biofilm formation. This review attempts to illustrate the complications associated with indwelling Foley catheters, primarily focussing on challenges in fighting CAUTI, catheter colonization, and biofilm formation. In this review, we also collate scientific literature on catheter modification using antibiotics, plant bioactive components, bacteriophages, nanoparticles, and studies demonstrating their efficacy through in vitro and in vivo testing.

Restoring bladder function using motor and sensory nerve transfers: a cadaveric feasibility study. J Neurosurg Spine 2023; 38:258-264. [PMID: 36208430 PMCID: PMC9898215 DOI: 10.3171/2022.8.spine22291] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 08/04/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVE Bladder dysfunction after nerve injury has a variable presentation, and extent of injury determines whether the bladder is spastic or atonic. The authors have proposed a series of 3 nerve transfers for functional innervation of the detrusor muscle and external urethral sphincter, along with sensory innervation to the genital dermatome. These transfers are applicable to only cases with low spinal segment injuries (sacral nerve root function is lost) and largely preserved lumbar function. Transfer of the posterior branch of the obturator nerve to the vesical branch of the pelvic nerve provides a feasible mechanism for patients to initiate detrusor contraction by thigh adduction. External urethra innervation (motor and sensory) may be accomplished by transfer of the vastus medialis nerve to the pudendal nerve. The sensory component of the pudendal nerve to the genitalia may be further enhanced by transfer of the saphenous nerve (sensory) to the pudendal nerve. The main limitations of coapting the nerve donors to their intrapelvic targets are the bifurcation or arborization points of the parent nerve. To ensure that the donor nerves had sufficient length and diameter, the authors sought to measure these parameters. METHODS Twenty-six pelvic and anterior thigh regions were dissected in 13 female cadavers. After the graft and donor sites were clearly exposed and the branches identified, the donor nerves were cut at suitable distal sites and then moved into the pelvis for tensionless anastomosis. Diameters were measured with calipers. RESULTS The obturator nerve was bifurcated a mean ± SD (range) of 5.5 ± 1.7 (2.0-9.0) cm proximal to the entrance of the obturator foramen. In every cadaver, the authors were able to bring the posterior division of the obturator nerve to the vesical branch of the pelvic nerve (located internal to the ischial spine) in a tensionless manner with an excess obturator nerve length of 2.0 ± 1.2 (0.0-5.0) cm. The distance between the femoral nerve arborization and the anterior superior iliac spine was 9.3 ± 1.8 (6.5-15.0) cm, and the distance from the femoral arborization to the ischial spine was 12.9 ± 1.4 (10.0-16.0) cm. Diameters were similar between donor and recipient nerves. CONCLUSIONS The chosen donor nerves were long enough and of sufficient caliber for the proposed nerve transfers and tensionless anastomosis.

Abstract
Traumatic spinal cord injury (TSCI) is a debilitating disease that poses significant functional and economic burden on both the individual and societal levels. Prognosis is dependent on the extent of the spinal injury and the severity of neurological dysfunction. If not treated rapidly, patients with TSCI can suffer further secondary damage and experience escalating disability and complications. It is important to quickly assess the patient to identify the location and severity of injury to make a decision to pursue a surgical and/or conservative management. However, there are many conditions that factor into the management of TSCI patients, ranging from the initial presentation of the patient to long-term care for optimal recovery. Here, we provide a comprehensive review of the etiologies of spinal cord injury and the complications that may arise, and present an algorithm to aid in the management of TSCI.

Abstract
Patients with neurological disorders often have lower urinary tract dysfunction, manifesting as urinary retention or urinary incontinence, and so commonly use catheters. Neurologists should therefore be aware of the different types of catheters and appliances and their risks, benefits and complications. Clean intermittent self-catheterisation is preferable to an indwelling catheter; however, if this is not possible, then a suprapubic indwelling catheter is preferable to a urethral catheter for long-term management. We review the decision-making process when selecting catheters for neurological patients, the evidence base regarding the different options and how neurologists can recognise and address complications. We also discuss alternatives to catheterisation, such as non-invasive containment products and surgical treatments, and the indications for urological referral.

Abstract
STUDY DESIGN A historical cohort study OBJECTIVES: The aim of the study was to examine the incidence of and predictive factors for VUR in individuals with suprasacral spinal cord injury (SCI). SETTING Srinagarind Hospital, Khon Kaen University, Thailand METHODS: Medical records were reviewed for all individuals with SCI and neurogenic bladder admitted for urological check-up between 1996 and 2016. The primary outcome was the cumulative incidence of VUR. The statistical tests used included the Nelson-Aalen Estimator and Cox Proportional Hazard Ratio. Harrell's C concordance statistic was used to evaluate the discrimination ability of the predictive model. RESULTS 293 participants with SCI (102 tetraplegic and 191 paraplegic) were included. Most participants were male (67%), and the median age was 52 years. The overall incidence of VUR was 7.5 cases per 100 person-years (95% CI, 6.15-9.4). In the multivariate analysis, the predictive factors for VUR were: (1) maximum detrusor pressure at first visit ≥ 75 cm of water (HRadj: 2.4 [95% CI: 1.4-4.1]); (2) indwelling urethral catheterization (IUC) (HRadj: 11.1 [95% CI: 3.9-31.7]) and clean intermittent catheterization (CIC) (HRadj: 6.5 [95% CI: 2.2-18.7]); (3) age ≥ 60 years at onset of SCI (HRadj: 1.7 [95% CI: 1.1-2.8]); and, (4) absence of antimuscarinic medication (HRadj: 3.8 [95% CI: 2.4-6.1]). The predictive model had an overall C-index of 0.78. CONCLUSIONS The incidence of VUR was high up to 12 years after SCI. High maximum detrusor pressure, IUC, age ≥ 60 years and absence of antimuscarinic medication were predictive factors for VUR.

Abstract
Myriad treatment modalities are available for neurogenic bladder (NGB) including behavioral therapies, oral pharmacotherapy, catheterization and surgical procedures. Little is known about how NGB patients are managed in the real world, how well patterns relate to clinical guidelines and how strategies may have changed over time. To address this gap, a systematic review (SR) was conducted using MEDLINE and EMBASE [1996–2017]. The inclusion criteria for studies were: (I) published in English; (II) conducted in human subjects; (III) reporting the treatment patterns/use in NGB; (IV) conducted in a real world setting. A narrative synthesis of results was conducted, comparing the results to current treatment guidelines. Percentage of treatment use was summarized using ranges. Eight studies met the inclusion criteria. Although most studies focused on spinal cord injuries (SCI), study designs and settings were heterogeneous. All data was collected before 2007. The most popular form of oral pharmacotherapy was antimuscarinics, used by 12.6–86.7% of patients; 0–100% of patients used catheterization techniques, 2.5–53.1% used reflex voiding (RV), and 0.2–55% underwent surgery. A notable amount of patients switched treatments. This SR revealed that numerous strategies have been used to manage NGB throughout the years and there has been a large variance in their use. Whilst there were some discrepancies, most practices matched recommendations made in current guidelines. Ultimately, this SR showed that there is a large gap of epidemiological studies conducted in the field of NGB and the authors felt that available data was insufficient to build a comprehensive picture of treatment patterns. Epidemiological studies using electronic medical records (EMRs) are necessary to advance our understanding of how treatment patterns have changed, and also build a comprehensive picture of how patients are managed in current practice.

Abstract
OBJECTIVE The aim of this study was to compare the biochemical parameters of the urine and blood in spinal cord injury (SCI) patients and healthy subjects. METHODS Thirty male patients with SCI were enrolled. Biochemical features of the urine and blood of the SCI patients were compared to healthy subjects. Extracted stones were analyzed by X-ray diffraction. RESULTS A total of 30 patients with SCI (mean age of 28.77 ± 7.3 years) and 10 healthy subjects (mean age of 27.6 + 6.2 years) were included. Among the patients with SCI; 12 of them (40%) had urinary stones and 18 of them (60%) did not. Urinary stone was localized in the kidneys and bladder in 25% and 75% of the subjects, respectively. The mean duration of cord injury at diagnosis of urinary stone was 9.2 ± 6 months. Urine cultures obtained on admission were negative for the control group, while the microorganism isolation rate was 73.3% in the SCI group. The urinary excretion of citrate and Mg were lower in the patient group compared with control group (p= 0.008, p= 0.001, respectively). As for the diffraction analysis of eight stones; five (62.5%) of the stones were calcium oxalate, two (25%) of them were calcium phosphate, and one (12.5%) was magnesium ammonium phosphate. CONCLUSION Both infection and metabolic changes play an important role in stones formation in SCI patients. The urinary excretion of citrate and Mg was decreased and urinary PH was increased in SCI patients.

Abstract
OBJECTIVES To observe neurogenic bladder pattern in patients with myelopathy by performing urodynamic study (UDS) and to observe whether it has any correlation with functional and neurological recovery. PATIENTS AND METHODS This prospective study was conducted with 90 patients with myelopathy, both traumatic and non-traumatic (males = 65) in a university tertiary research hospital in India between January 2011 and December 2013. Mean age was 33.5 ± 13.2 years (range 15-65 years), mean duration of injury was 82.63 ± 88.3 days (range 14-365 days) and mean length of stay (LOS) in the rehabilitation unit 42.5 ± 23.3 days (range 14-130 days). The urodynamic study was performed in all the patients to assess the neurogenic bladder pattern. Management was based on the UDS findings. Functional recovery was assessed using Barthel index (BI) scores and spinal cord independence measures (SCIM) scores. Neurological recovery was assessed using ASIA impairment scale (AIS). We tried to correlate neurogenic bladder patterns with recovery. RESULTS Fifty patients (55.6%) had overactive detrusor with 25 each had detrusor sphincter dyssynergia (DSD) and synergic sphincter. Thirty-eight patients had hypoactive/acontractile detrusor and two had normal studies. No significant correlation observed between neurogenic bladder pattern and change in BI scores (P = 0.696), SCIM scores (P = 0.135) or change in ASIA status (P = 0.841) in the study. CONCLUSIONS More than half of the patients with myelopathies had overactive detrusor with or without dyssynergic sphincter according to the urodynamic study. Neurogenic bladder patterns had no significant correlation with functional and neurological recovery in these patients.

Lack of improvement after audit assessing the management of voiding dysfunction in patients with spinal cord injury: necessity for institutional guidelines. Int J Surg 2011; 9:302-5. [PMID: 21278004 DOI: 10.1016/j.ijsu.2011.01.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2010] [Revised: 01/03/2011] [Accepted: 01/13/2011] [Indexed: 11/22/2022]
Abstract
INTRODUCTION Standard management guidelines for voiding dysfunction in patients with spinal cord injury (SCI) do not exist and these patients are managed on the basis of institutional protocols or individual judgment of managing physicians. OBJECTIVES To notice general trends and improvements over a five-year period, in the institutional practices related to management of voiding dysfunction in SCI patients. METHODOLOGY A retrospective cross-sectional study was conducted by Neurosurgery and Urology services together. A nine years (June 1995-June 2004) internal clinical audit of urological management of SCI patients was compared with a similar audit conducted five years later (January 2008-June 2010). Comparisons were made using chi-square test. A p-value of <0.05 was considered statistically significant. RESULTS A total of 146 patients were compared (89-pre-audit, 57-post-audit). The quality of documentation of examination findings worsened over the two study periods (p = 0.002). Although determination of baseline serum creatinine improved to statistically significant levels (p = 0.019), no imaging for the kidneys was performed as baseline in the post-audit period (p = 0.000). Similarly the number of urodynamic studies performed decreased from 11% to 1.75% (p = 0.045). The number of urological consultations, however, increased from 26% to 31.58% (p = 0.452). During follow-up, only 17 (19.1%) patients in the pre-audit study period and 6 (10.5%) in the post-audit study period were voiding spontaneously. CONCLUSION Our study of two eras clearly demonstrated a worsening trend in quality of patient management, which can be corrected by agreeing upon and implementing standard guidelines for management of SCI patients.
