Management of febrile infants aged 1 month and less than 3 months in a French university hospital: Clinical practice evaluation.

BACKGROUND: Management of febrile infants is challenging due to the increased risk of serious bacterial infections and it varies among physicians and hospitals. The goals of this study were to describe and compare the management of febrile infants aged 1-2 months in a hospital in 2011 and 2016. METHODS: We conducted a retrospective study in the Bordeaux Pellegrin University Hospital, France, in 2011 and 2016. All infants aged 1-2 months with diagnosis codes referring to fever were included. Data on infant characteristics, fever episodes, clinical symptoms, and management were collected from medical charts. Univariate analyses and multivariate logistic models were used. RESULTS: A total of 530 infants were included; 89.2% had blood testing and 81.1% urine testing; 79.6% of the infants were hospitalized, three of them in the pediatric intensive care unit. The median hospitalization duration was 3 days. In the sample investigated, 59.8% of the infants received antibiotic therapy and 128 (24.1%) had bacterial infections with no difference between 2011 and 2016. The main bacterial infection was pyelonephritis (86.7%). Urethral catheterization was implemented in 2016, whereas a urine bag was utilized for 174 out of 177 infants in 2011. The percentage of contaminated urine cultures was higher in 2011 (35.9%) than in 2016 (19.6%, P<0.001). The hospitalization rate was higher in 2016. CONCLUSIONS: Management of febrile infants changed between 2011 and 2016. The hospitalization rate and antibiotic therapy use remained high regarding the rate of bacterial infection. Use of urethral catheterization decreased the level of contamination.

Ins and outs of urinary catheters

BACKGROUND: Inserting an indwelling catheter (IDC) is a common medical procedure that is often performed poorly and inappropriately, and can lead to significant morbidity. Although most catheterisations are performed by nursing staff, medical personnel need to be aware of the procedure, products and common IDC complications. OBJECTIVE: Current guidelines and literature were reviewed to outline catheterisation indications, catheter types and provide a general understanding of complications associated with IDCs for the general practitioner (GP). DISCUSSION: There is evidence that IDCs are often used when not indicated and improperly managed when inserted. IDCs can cause significant morbidity, prolong hospital stay and increase healthcare costs. Infection and traumatic insertion are common complications; advances in catheter design have helped to limit these complications. Most complications are avoidable, do not require specialist input and can be managed by community nurses or GPs. Reviewing indications, adopting proper technique for insertion and defining management strategies can limit complications.

Suprapubic tube versus urethral catheter drainage after robot-assisted radical prostatectomy: a systematic review and meta-analysis.

BACKGROUND: Prostate cancer is one of the most common cancers in the elderly population. The standard treatment is radical prostatectomy (RARP). However, urologists do not have consents on the postoperative urine drainage management (suprapubic tube (ST)/ urethral catheter (UC)). Thus, we try to compare ST drainage to UC drainage after robot-assisted radical prostatectomy regarding to comfort, recovery rate and continence using the method of meta-analysis. METHODS: A systematic search was performed in Dec. 2017 on PubMed, Medline, Embase and Cochrane Library databases. The authors independently reviewed the records to identify studies comparing ST with UC of patients underwent RARP. Meta-analysis was performed using the extracted data from the selected studies. RESULTS: Seven studies, including 3 RCTs, with a total of 946 patients met the inclusion criteria and were included in our meta-analysis. Though there was no significant difference between the ST group and the UC group on postoperative pain (RR1.73, P 0.20), our study showed a significant improvement on bother or discomfort, defined as trouble in hygiene and sleep, caused by catheter when compared two groups at postoperative day (POD) 7 in ST group (RR2.05, P 0.006). There was no significant difference between the ST group and UC group on urinary continence (RR0.98, P 0.74) and emergency department visit (RR0.61, P 0.11). The rates of bladder neck contracture and other complications were very low in both groups. CONCLUSION: Compared to UC, ST showed a weak advantage. So it might be a good choice to choose ST over RARP.

Effect of imidafenacin on the urodynamic parameters of patients with indwelling bladder catheters due to spinal cord injury.

STUDY DESIGN: A retrospective study. OBJECTIVES: To investigate the effect of imidafenacin on the urodynamic parameters of patients with indwelling bladder catheters due to spinal cord injury (SCI). SETTING: Spinal center (Tokyo, Japan). METHODS: Imidafenacin was prescribed to 34 patients with SCI who had a low cystometric volume and/or detrusor compliance according to a urodynamic study. A low cystometric volume and detrusor compliance were defined as <200 ml and <20 ml cm-1 H2O, respectively. The urodynamic study was repeated 4 weeks after imidafenacin was prescribed. When the urodynamic parameters did not improve in the follow-up study, the dose of imidafenacin was increased twofold. Then the urodynamic study was repeated 4 weeks thereafter. We compared the urodynamic parameters before and after imidafenacin treatment. Complications such as vesico-urethral reflux (VUR) and autonomic dysreflexia (AD) were documented. RESULTS: Fifteen patients took 0.2 mg of imidafenacin daily, and 19 received 0.4 mg of imidafenacin daily. Imidafenacin increased the cystometric volume from 246.0 to 321.5 ml (median, P=0.002), detrusor compliance from 6.67 ml cm-1 H2O to 8.98 ml cm-1 H2O (median, P=0.012), and decreased the detrusor pressure from 37.0 cm H2O to 30.5 cm H2O (median, P=0.056). All three patients who had VUR fully recovered. Although 3 of 12 patients recovered from AD, 3 patients newly developed symptoms of AD. No patient withdrew from treatment due to adverse effects. CONCLUSION: Imidafenacin is a safe drug that may improve the urodynamic parameters of patients with SCI, and it possibly alleviates bladder complications.

Death of the Safety Guidewire.

The safety guidewire has been an integral tool in endourologic percutaneous and ureteroscopic procedures for the last three decades, providing access to the collecting system or ureter in the event of loss of renal contact or ureteral perforation, respectively. However, recent advances in endourologic techniques and instrumentation have obviated the need of routine safety guidewire placement. Today the establishment of a "through-and-through" flank to urethral meatus guidewire eliminates the need of an additional guidewire during percutaneous procedures. Likewise, the availability of smaller flexible ureteroscopes, as well as modern ureteral access sheaths, has reduced the necessity of safety guidewire placement in ureteroscopic procedures. Herein, we trace the historical development of the safety guidewire concept, review recent advances in technologies that have obsoleted the safety guidewire, and evaluate recent data suggesting that continued use of a safety guidewire during ureteroscopic procedures may indeed be counterproductive.

Treatment of urethral strictures with balloon dilation: A forgotten tale.

Urethral stricture is a common condition that can lead to serious complications such as urinary infections and renal insufficiency secondary to urinary retention. Treatment options include catheterization and dilation, urethroplasty and endoscopic internal urethrotomy as well. Although treatment option depends on the type, length and aetiology of stricture, the choice can be influenced to varying degrees by the simplicity of the method, the preferences of the patient the available accoutrements and the patient health condition. Both urethroplasty and endoscopic internal urethrotomy require anaesthesia and thus are not suitable for many elder and unfit for surgical treatment patients. On the other hand, dilations are easy to perform in every day clinical practice however they have been associated with iatrogenic urethral trauma. In contrast, balloon dilation under vision dilates by radial application of forces against the stricture, avoiding the potentially shearing forces associated with sequential rigid dilation. Since it reduces the possibility of an iatrogenic urethral trauma and the subsequent spongiofibrosis may lead into improved therapeutic outcomes. In this report we describe a technique for the treatment of urethral strictures with balloon dilation in elder and unfit for surgical treatment patients.

Managing urinary incontinence: what works?

Urinary incontinence is a common condition, which, although not life-threatening, impairs the health-related quality of life of affected individuals. All women complaining of incontinence require a basic assessment and those with complex or refractory symptoms may benefit from urodynamic studies. Initial treatment includes lifestyle advice, behavioral modifications, bladder retraining and pelvic floor muscle training. For those women with persistent stress urinary incontinence following conservative therapy, surgical management might be considered. The development of the minimally invasive, retropubic, synthetic, mid-urethral sling procedures has revolutionized stress incontinence surgery and reduced the popularity of 'traditional' procedures, such as colposuspension and autologous fascial sling. In an attempt to reduce further the morbidity, transobturator and single-incision slings have been introduced. While antimuscarinic agents are the mainstay of the current medical management of urgency urinary incontinence, a recently developed selective ß3-adrenergic receptor agonist (mirabegron) offers an alternative pharmacological option. Modalities such as intravesical botulinum toxin and neuromodulation (peripheral or sacral) are available to women with refractory urgency incontinence. Finally, when all other options have been explored and proven unsuccessful, inappropriate or not feasible, reconstructive surgery or catheter insertion might be considered as a last resort. The aim of this paper is to review conservative, medical and surgical management for urinary incontinence by using the best available evidence in the literature.

A multimodal intervention to reduce urinary catheter use and associated infection at a Veterans Affairs Medical Center.

We assessed the impact of a quality improvement intervention to reduce urinary catheter use and associated urinary tract infections (UTIs) at a single hospital. After implementation, UTIs were reduced by 39% ([Formula: see text]). Additionally, we observed a slight decrease in catheter use and the number of catheters without an appropriate indication.

Temporal trends, practice patterns, and treatment outcomes for infected upper urinary tract stones in the United States.

BACKGROUND: The incidence of infected urolithiasis is unknown, and evidence describing the optimal management strategy for obstruction is equivocal. OBJECTIVE: To examine the trends of infected urolithiasis in the United States, the practice patterns of competing treatment modalities, and to compare adverse outcomes. DESIGN, SETTING, AND PARTICIPANTS: A weighted estimate of 396385 adult patients hospitalized with infected urolithiasis was extracted from the Nationwide Inpatient Sample, 1999-2009. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Time trend analysis examined the incidence of infected urolithiasis and associated sepsis, as well as rates of retrograde ureteral catheterization and percutaneous nephrostomy (PCN) for urgent/emergent decompression. Propensity-score matching compared the rates of adverse outcomes between approaches. RESULTS AND LIMITATIONS: Between 1999 and 2009, the incidence of infected urolithiasis in women increased from 15.5 (95% confidence interval [CI], 15.3-15.6) to 27.6 (27.4-27.8)/100 000); men increased from 7.8 (7.7-7.9) to 12.1 (12.0-12.3)/100000. Rates of associated sepsis increased from 6.9% to 8.5% (p=0.013), and severe sepsis increased from 1.7% to 3.2% (p<0.001); mortality rates remained stable at 0.25-0.20% (p=0.150). Among those undergoing immediate decompression, 113 459 (28.6%), PCN utilization decreased from 16.1% to 11.2% (p=0.001), with significant regional variability. In matched analysis, PCN showed higher rates of sepsis (odds ratio [OR]: 1.63; 95% CI, 1.52-1.74), severe sepsis (OR: 2.28; 95% CI, 2.06-2.52), prolonged length of stay (OR: 3.18; 95% CI, 3.01-3.34), elevated hospital charges (OR: 2.71; 95%CI, 2.57-2.85), and mortality (OR: 3.14; 95%CI, 13-4.63). However, observational data preclude the assessment of timing between outcome and intervention, and disease severity. CONCLUSIONS: Between 1999 and 2009, women were twice as likely to have infected urolithiasis. Rates of associated sepsis and severe sepsis increased, but mortality rates remained stable. Analysis of competing treatment strategies for immediate decompression demonstrates decreasing utilization of PCN, which showed higher rates of adverse outcomes. These findings should be viewed as preliminary and hypothesis generating, demonstrating the pressing need for further study.

New strategies to prevent catheter-associated urinary tract infections.

Catheter-associated urinary tract infection (CAUTI) is the most common health-care-associated infection worldwide. Although not all cases of bacteriuria result in clinical infection, several hundred thousand episodes of CAUTI occur each year in the USA alone. The milieu in which the catheter is placed is highly conducive to bacterial colonization, biofilm formation on the catheter surface, and inevitable catheter-associated bacteriuria. A multitude of novel methods of CAUTI prevention have been described, including established approaches that are routinely recommended, such as the use of a secured, closed, silicone urinary catheter drainage system that mimics normal voiding, and newer strategies focusing on biocompatible catheter materials that cause minimal host inflammatory response and retard biofilm formation. Much recent research has focused on modification of the catheter surface by either coating or impregnation with antimicrobials or antiseptics. However, clinical trials that analyse cost-effectiveness and rates of antimicrobial resistance are awaited. More recently, innovative use of iontophoresis, vibroacoustic stimulation, bacterial interference and bacteriophage cocktails has been reported.
