Patient-reported signs and symptoms of urinary tract infections after video-urodynamic studies in individuals with neurogenic lower urinary tract dysfunction-A single-center observational study. Neurourol Urodyn 2024; 43:1609-1616. [PMID: 38801121 DOI: 10.1002/nau.25516] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 05/03/2024] [Accepted: 05/20/2024] [Indexed: 05/29/2024]
Abstract
BACKGROUND Video-urodynamic studies (VUDS) are the recommended standard of diagnostic care to objectively assess neurogenic lower urinary tract dysfunction (NLUTD) in individuals with spinal cord injury/disease (SCI/D). This examination requires the insertion of a catheter into the bladder, which increases the risk of a urinary tract infection (UTI). Data on symptomatic UTIs after VUDS are limited. METHODS A single-center, observational study was conducted to evaluate the incidence of patient-reported UTI signs and symptoms 7 days after VUDS. No peri-interventional antibiotics were administered. The effect of sex, age, SCI/D duration, bladder evacuation method, bacteriuria, UTI prophylaxis, UTI history, or unfavorable VUDS results on the occurrence of patient-reported UTI signs or symptoms after VUDS was examined using binary logistic regression analysis. RESULTS A total of 140 individuals with a mean age of 59.1 ± 14.0 years and a median SCI/D duration of 15.0 years (6/29 years) were evaluated. Seven days (mean 7 ± 1 days) after VUDS, 42 (30%) individuals reported at least one UTI sign or symptom. In the majority, signs and symptoms resolved without the need for antibiotic treatment, which was required in seven participants (5%). Male sex significantly (p = 0.04) increased the odds (odds ratio 3.74) of experiencing UTI signs and symptoms after VUDS. CONCLUSIONS In individuals with NLUTD, 30% experienced UTI signs and symptoms 1 week after VUDS. However, these signs and symptoms were transient and only 5% required antibiotic treatment. Thus, antibiotic prophylaxis does not seem necessary in all individuals with SCI/D undergoing VUDS.

Abstract
PURPOSE To assess the performance of a new urinary intermittent catheter (IC) prototype designed with a micro-hole drainage zone compared to a conventional eyelet catheter (CEC) in terms of flow-stop, bladder emptying, and hematuria. DESIGN Randomized controlled crossover studies. SUBJECT AND SETTING The sample comprised 15 male healthy volunteers (HV) and 15 IC users, along with 15 female HV and 15 IC users. The age range was lower for HV participants than for IC users (range: 20-57 years for HV vs 21-82 years for IC users). The study setting was the Department of Urology, located in Rigshospitalet, Copenhagen. METHODS Number of flow-stop incidents, residual urine volume at first flow-stop (RV1), and dipstick hematuria were measured during and after catheterization by a health care professional (HV) and by self-catheterisation (IC-users). Results from the 3 studies were combined for HV and IC users on RV1 and number of flow-stop incidents but separated on sex. For incidents of hematuria, an effect of underlying condition was assumed, and a combined analysis on sex was performed, separating HV and IC users. RESULTS When compared to the micro-hole drainage zone design, catheterizations with CEC resulted in a significantly higher mean RV1 (mean difference: 49 mL in males and 32 mL in females, both P < .001) and average number of flow-stop incidents (8 and 21 times more frequent for males and females, respectively, both P < .001). The likelihood for hematuria was 5.84 higher with CEC than with micro-hole drainage hole design, P = .053, during normal micturition in HV postcatheterization. No serious adverse events were reported. CONCLUSION The micro-hole drainage zone catheter provides IC users fewer premature flow-stops. This design feature reduces modifiable urinary tract infection risk factors, such as residual urine and micro-trauma; additional research is needed to determine its effects on bladder health.

Definitions of Urinary Tract Infection Used in Interventional Studies Involving Neurourological Patients-A Systematic Review. Eur Urol Focus 2022; 8:1386-1398.

Abstract
CONTEXT Neurourological patients often encounter bacteriuria without any symptoms or may experience symptoms suspicious of urinary tract infections (UTIs). However, there is a lack of guidelines that unequivocally state the definition of UTIs in this specific patient group. OBJECTIVE To present all used definitions of UTIs in neurourological patients. EVIDENCE ACQUISITION This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Studies were identified by electronic search of Medline, Embase, Cochrane controlled trials databases, and clinicaltrial.gov without a time limitation (last search September 2020) and by screening of reference lists and reviews. The occurrences of the various UTI definitions were counted and the frequencies calculated. EVIDENCE SYNTHESIS After screening 7164 abstracts, we included 32 studies enrolling a total of 8488 patients with a neurourological disorder who took part in an interventional clinical study. UTI definitions were heterogeneous. The concordance to predefined definitions was low. CONCLUSIONS Interventional clinical studies rarely report specific definitions for UTIs, and both clinical and laboratory criteria used are heterogeneous. A generally accepted UTI definition for neurourological patients is urgently needed. PATIENT SUMMARY Patients suffering from neurological disorders often experience symptoms in their lower urinary tract that resemble urinary tract infections. Furthermore, they can have positive urine cultures without symptoms (the so-called asymptomatic bacteriuria). However, clinical studies rarely report specific definitions for urinary tract infections, and when it is done, they are heterogeneous. A generally accepted urinary tract infection definition for neurourological patients is urgently needed. TAKE HOME MESSAGE: Interventional clinical studies on neurourological patients rarely report specific definitions for urinary tract infections (UTIs), and both clinical and laboratory criteria used are heterogeneous. A generally accepted UTI definition for neurourological patients is urgently needed.

The frequency of urinary tract infections and the value of antiseptics in community-dwelling people who undertake intermittent urinary catheterization: A systematic review. Am J Infect Control 2021; 49:1058-1065.

Abstract
BACKGROUND This systematic review had 2 aims. First to identify the incidence of urinary tract infection (UTI) and bacteriuria in people undertaking intermittent catheterization (IC), second to determine the effectiveness of antiseptic cleaning of the meatal area prior to IC in reducing the incidence of UTI and bacteriuria. METHODS A systematic review was conducted. Medline and the Cumulative Index to Nursing and Allied Health Literature electronic databases were systematically searched between January 1, 1990 and January 31, 2020, to identify studies that reported either the incidence of UTI or bacteriuria or the impact of using antiseptics for meatal cleaning prior to IC on incidence of these same outcomes. RESULTS Twenty-five articles were identified for the first aim, 2 articles for the second. The proportion of participants experiencing ≥1 UTIs per year ranged from 15.4% to 86.6%. Synthesis of these studies suggest a combined incidence of 44.2% (95%CI 40.2%-48.5%) of participants having ≥1 UTIs per year. One of the 2 studies exploring the benefit of antiseptics in reducing UTI suggest some potential benefit of using chlorhexidine in reducing UTIs. Both studies have significant limitations, making interpretation difficult. CONCLUSIONS A large proportion of people undertaking IC in the community have UTIs each year. Evidence on the role of antiseptics in the prevention of UTI for people who undertake IC remains unclear.

Abstract
A risk factor model for urinary tract infections in patients with adult neurogenic lower urinary tract dysfunction performing clean intermittent catheterisation was developed; it consists of four domains, namely, (1) general (systemic) conditions in the patient, (2) individual urinary tract conditions in the patient, (3) routine aspects related to the patient, and (4) factors related to intermittent catheters per se. The conceptual model primarily concerns patients with spinal cord injury, spina bifida, multiple sclerosis, or cauda equina where intermittent catheterisation is a normal part of the bladder management. On basis of several literature searches and author consensus in case of lacking evidence, the model intends to provide an overview of the risk factors involved in urinary tract infections, with specific emphasis to describe those that in daily practice can be handled and modified by the clinician and so come to the benefit of the individual catheter user in terms of fewer urinary tract infections.

Abstract
OBJECTIVES To review the physiology of micturition, the pathophysiology of micturition disorders, and current pharmacological agents used to treat these disorders. To discuss different urinary catheterization techniques, along with the risks of catheter-associated urinary tract infections attributed with these techniques. ETIOLOGY Many critically ill veterinary patients are at risk of developing a number of neurological and non neurological micturition-related disorders. DIAGNOSIS Micturition disorders can be diagnosed based on physical examination findings, urinary voiding contrast studies, urethral pressure profiles, and diagnostic testing such as urinalysis and urine cultures. THERAPY Therapy can be either pharmacological, involvement of urinary catheterization, surgical, or a combination of all the above. The goal of the treatment is to correct the underlying causes resulting in the micturition-related disorder, and if possible, allow the patient to regain their normal physiological micturition behavior. PROGNOSIS Depending on the underlying disease process and duration of the micturition disorder, the prognosis can be variable. In many instances, near-normal or normal function can return, but in severe cases, the patient may not regain its normal, appropriate micturition response.

Abstract
AIMS To investigate the long-term course of the detrusor pressure during sacral anterior root stimulation in spinal cord injury (SCI) patients. METHODS Retrospective evaluation of 111 patients who had undergone sacral deafferentation and implantation of an anterior root stimulator at a single SCI rehabilitation center with a minimum follow-up time of 5 years. RESULTS The median follow-up time was 11.7 years (range 5.0-24.9 years). The maximum detrusor pressure (Pdet_max) during stimulation was higher in men compared to women (P = 0.0004) and decreased over time (P = 0.0006). However, there were no significant (P ≥ 0.06) differences in the median Pdet_max during stimulation between the first measurement time point and any follow-up time point. The Pdet_max during stimulation decreased from 62 cmH2 O (95%CI 57-73 cmH2 O) to 53 cmH2 O (95%CI 47-69 cmH2 O) (P = 0.9). The time had also a significant effect on Pdet_max during the storage phase (P < 0.0001) and bladder compliance (P = 0.0007). The Pdet_max during the storage phase decreased, whereas bladder compliance increased during the follow-up period. There were no significant (P ≥ 0.1) changes over time in bladder capacity, the number of daily stimulations and the residual urine volume after voiding. CONCLUSIONS The detrusor pressure during sacral anterior root stimulation decreases over time in SCI individuals. However, the changes do not seem to be clinically relevant during the first decade after surgery.

Abstract
STUDY DESIGN Retrospective investigation. OBJECTIVES To investigate the association of patient and injury characteristics, as well as bladder management, with the occurrence of patient-reported, symptomatic urinary tract infection(s) UTI(s) in patients with chronic neurogenic lower urinary tract dysfunction (NLUTD). SETTING Tertiary urologic referral center. METHODS The patient database was screened for patients with chronic (>12 months) NLUTD who had presented between 2008 and 2012. Patient characteristics, bladder evacuation management, the annual number of patient-reported, symptomatic UTIs and the type of prophylactic treatment to prevent UTIs were collected. Binary logistic regression analysis was used to investigate the effects of the investigated risk factors on the occurrence of symptomatic UTI(s) and recurrent symptomatic UTIs (⩾3 annual UTIs). RESULTS The data of 1104 patients with a mean NLTUD duration of 20.3±11.6 years were investigated. The evacuation method was a significant (P⩽0.004) predictor for the occurrence of symptomatic UTI and recurrent symptomatic UTIs. The greatest annual number of symptomatic UTIs was observed in patients using transurethral indwelling catheters, and the odds of experiencing a UTI and recurrent UTIs were increased more than 10- and 4-fold, respectively. The odds of a UTI or recurrent UTIs were also increased significantly (P⩽0.014) in patients using intermittent catheterization (IC). Botulinum toxin injections into the detrusor increased the odds of a UTI ~10-fold (P=0.03). CONCLUSIONS The bladder evacuation method is the main predictor for symptomatic UTIs in individuals with NLUTD. Transurethral catheters showed the highest odds of symptomatic UTI and should be avoided whenever possible.

Abstract
The heart and the urinary bladder are hollow muscular organs, which can be afflicted by pressure overload injury due to pathological conditions such as hypertension and bladder outlet obstruction. This increased outflow resistance induces hypertrophy, marked by dramatic changes in the organs' phenotype and function. The end result in both the heart and the bladder can be acute organ failure due to advanced fibrosis and the subsequent loss of contractility. There is emerging evidence that microRNAs (miRNAs) play an important role in the pathogenesis of heart failure and bladder dysfunction. MiRNAs are endogenous non-coding single-stranded RNAs, which regulate gene expression and control adaptive and maladaptive organ remodeling processes. This Review summarizes the current knowledge of molecular alterations in the heart and the bladder and highlights common signaling pathways and regulatory events. The miRNA expression analysis and experimental target validation done in the heart provide a valuable source of information for investigators working on the bladder and other organs undergoing the process of fibrotic remodeling. Aberrantly expressed miRNA are amendable to pharmacological manipulation, offering an opportunity for development of new therapies for cardiac and bladder hypertrophy and failure.

Abstract
STUDY DESIGN Retrospective investigation. OBJECTIVES To investigate the occurrence, characteristics and clinical consequences of urethral strictures in men with neurogenic lower urinary tract dysfunction (NLUTD) using intermittent catheterization (IC) for bladder evacuation. SETTING Spinal cord injury rehabilitation center. METHODS The patient database was screened for men with NLUTD who had presented for a routine video-urodynamic investigation between 2008 and 2012. Patient characteristics, bladder diary details, the occurrence of urethral strictures and performed urethrotomy procedures were collected from patient charts. Urethral strictures were classified using the Wiegand scoring system modified for men with NLUTD. RESULTS The occurrence rate of urethral strictures (that is, 25% confidence interval (CI) 21-30%) was significantly (P=0.0001) higher in men using IC (n=415) than in men using other bladder evacuation methods (that is, 14% CI 11-17%) (n=629). Urethral strictures had occurred after a median 5.9 years (range 0.5-48.9 years) of IC. There was no significant (P>0.08) effect of tetraplegia or catheter type on the stricture occurrence rate. Approximately one-third of the men suffering from urethral strictures underwent internal urethrotomies. The radiographic stricture severity score was not associated with the need for surgical correction of the stricture. The radiographic recurrence rate of urethral strictures in operated men was 100%, a median 14 years after the first urethrotomy. CONCLUSIONS The occurrence rate of urethral strictures is significantly higher in men using IC than in men using other bladder evacuation methods. Every fourth men using IC may be affected by urethral strictures. However, only every third stricture may require a surgical intervention.
