BACKGROUND
Urinary Tract Infection (UTI) is a common infection in children. Prompt diagnosis and appropriate treatment are very important to reduce the morbidity associated with this condition.
OBJECTIVE
To provide an update on the evaluation, diagnosis, and treatment of urinary tract infection in children.
METHODS
A PubMed search was completed in clinical queries using the key terms "urinary tract infection", "pyelonephritis" OR "cystitis". The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to English literature and the pediatric age group. Patents were searched using the key terms "urinary tract infection" "pyelonephritis" OR "cystitis" from www.google.com/patents, http://espacenet.com, and www.freepatentsonline.com.
RESULTS
Escherichia coli accounts for 80 to 90% of UTI in children. The symptoms and signs are nonspecific throughout infancy. Unexplained fever is the most common symptom of UTI during the first two years of life. After the second year of life, symptoms and signs of pyelonephritis include fever, chills, rigor, flank pain, and costovertebral angle tenderness. Lower tract symptoms and signs include suprapubic pain, dysuria, urinary frequency, urgency, cloudy urine, malodorous urine, and suprapubic tenderness. A urinalysis and urine culture should be performed when UTI is suspected. In the work-up of children with UTI, physicians must judiciously utilize imaging studies to minimize exposure of children to radiation. While waiting for the culture results, prompt antibiotic therapy is indicated for symptomatic UTI based on clinical findings and positive urinalysis to eradicate the infection and improve clinical outcome. The choice of antibiotics should take into consideration local data on antibiotic resistance patterns. Recent patents related to the management of UTI are discussed.
CONCLUSION
Currently, a second or third generation cephalosporin and amoxicillin-clavulanate are drugs of choice in the treatment of acute uncomplicated UTI. Parenteral antibiotic therapy is recommended for infants ≤ 2 months and any child who is toxic-looking, hemodynamically unstable, immunocompromised, unable to tolerate oral medication, or not responding to oral medication. A combination of intravenous ampicillin and intravenous/intramuscular gentamycin or a third-generation cephalosporin can be used in those situations. Routine antimicrobial prophylaxis is rarely justified, but continuous antimicrobial prophylaxis should be considered for children with frequent febrile UTI.

Review
Urinary tract infections are the most common bacterial infections in women. Most urinary tract infections are acute uncomplicated cystitis. Identifiers of acute uncomplicated cystitis are frequency and dysuria in an immunocompetent woman of childbearing age who has no comorbidities or urologic abnormalities. Physical examination is typically normal or positive for suprapubic tenderness. A urinalysis, but not urine culture, is recommended in making the diagnosis. Guidelines recommend three options for first-line treatment of acute uncomplicated cystitis: fosfomycin, nitrofurantoin, and trimethoprim/sulfamethoxazole (in regions where the prevalence of Escherichia coli resistance does not exceed 20 percent). Beta-lactam antibiotics, amoxicillin/clavulanate, cefaclor, cefdinir, and cefpodoxime are not recommended for initial treatment because of concerns about resistance. Urine cultures are recommended in women with suspected pyelonephritis, women with symptoms that do not resolve or that recur within two to four weeks after completing treatment, and women who present with atypical symptoms.

The most common cause of acute dysuria is infection, especially cystitis. Other infectious causes include urethritis, sexually transmitted infections, and vaginitis. Noninfectious inflammatory causes include a foreign body in the urinary tract and dermatologic conditions. Noninflammatory causes of dysuria include medication use, urethral anatomic abnormalities, local trauma, and interstitial cystitis/bladder pain syndrome. An initial targeted history includes features of a local cause (e.g., vaginal or urethral irritation), risk factors for a complicated urinary tract infection (e.g., male sex, pregnancy, presence of urologic obstruction, recent procedure), and symptoms of pyelonephritis. Women with dysuria who have no complicating features can be treated for cystitis without further diagnostic evaluation. Women with vulvovaginal symptoms should be evaluated for vaginitis. Any complicating features or recurrent symptoms warrant a history, physical examination, urinalysis, and urine culture. Findings from the secondary evaluation, selected laboratory tests, and directed imaging studies enable physicians to progress through a logical evaluation and determine the cause of dysuria or make an appropriate referral.

Meta-Analysis
BACKGROUND
Urinary catheterisation is a common procedure, with approximately 15% to 25% of all people admitted to hospital receiving short-term (14 days or less) indwelling urethral catheterisation at some point during their care. However, the use of urinary catheters is associated with an increased risk of developing urinary tract infection. Catheter-associated urinary tract infection (CAUTI) is one of the most common hospital-acquired infections. It is estimated that around 20% of hospital-acquired bacteraemias arise from the urinary tract and are associated with mortality of around 10%. This is an update of a Cochrane Review first published in 2005 and last published in 2007.
OBJECTIVES
To assess the effects of strategies for removing short-term (14 days or less) indwelling catheters in adults.
SEARCH METHODS
We searched the Cochrane Incontinence Specialised Register, which contains trials identified from CENTRAL, MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, CINAHL, ClinicalTrials.gov, WHO ICTRP, and handsearching of journals and conference proceedings (searched 17 March 2020), and reference lists of relevant articles.
SELECTION CRITERIA
We included all randomised controlled trials (RCTs) and quasi-RCTs that evaluated the effectiveness of practices undertaken for the removal of short-term indwelling urethral catheters in adults for any reason in any setting.
DATA COLLECTION AND ANALYSIS
Two review authors performed abstract and full-text screening of all relevant articles. At least two review authors independently performed risk of bias assessment, data abstraction and GRADE assessment.
MAIN RESULTS
We included 99 trials involving 12,241 participants. We judged the majority of trials to be at low or unclear risk of selection and detection bias, with a high risk of performance bias. We also deemed most trials to be at low risk of attrition and reporting bias. None of the trials reported on quality of life. The majority of participants across the trials had undergone some form of surgical procedure. Thirteen trials involving 1506 participants compared the removal of short-term indwelling urethral catheters at one time of day (early morning removal group between 6 am to 7 am) versus another (late night removal group between 10 pm to midnight). Catheter removal late at night may slightly reduce the risk of requiring recatheterisation compared with early morning (RR 0.71, 95% CI 0.53 to 0.96; 10 RCTs, 1920 participants; low-certainty evidence). We are uncertain if there is any difference between early morning and late night removal in the risk of developing symptomatic CAUTI (RR 1.00, 95% CI 0.61 to 1.63; 1 RCT, 41 participants; very low-certainty evidence). We are uncertain whether the time of day makes a difference to the risk of dysuria (RR 2.20; 95% CI 0.70 to 6.86; 1 RCT, 170 participants; low-certainty evidence). Sixty-eight trials involving 9247 participants compared shorter versus longer durations of catheterisation. Shorter durations may increase the risk of requiring recatheterisation compared with longer durations (RR 1.81, 95% CI 1.35 to 2.41; 44 trials, 5870 participants; low-certainty evidence), but probably reduce the risk of symptomatic CAUTI (RR 0.52, 95% CI 0.45 to 0.61; 41 RCTs, 5759 participants; moderate-certainty evidence) and may reduce the risk of dysuria (RR 0.42, 95% CI 0.20 to 0.88; 7 RCTs; 1398 participants; low-certainty evidence). Seven trials involving 714 participants compared policies of clamping catheters versus free drainage. There may be little to no difference between clamping and free drainage in terms of the risk of requiring recatheterisation (RR 0.82, 95% CI 0.55 to 1.21; 5 RCTs; 569 participants; low-certainty evidence). We are uncertain if there is any difference in the risk of symptomatic CAUTI (RR 0.99, 95% CI 0.60 to 1.63; 2 RCTs, 267 participants; very low-certainty evidence) or dysuria (RR 0.84, 95% CI 0.46 to 1.54; 1 trial, 79 participants; very low-certainty evidence). Three trials involving 402 participants compared the use of prophylactic alpha blockers versus no intervention or placebo. We are uncertain if prophylactic alpha blockers before catheter removal has any effect on the risk of requiring recatheterisation (RR 1.18, 95% CI 0.58 to 2.42; 2 RCTs, 184 participants; very low-certainty evidence) or risk of symptomatic CAUTI (RR 0.20, 95% CI 0.01 to 4.06; 1 trial, 94 participants; very low-certainty evidence). None of the included trials investigating prophylactic alpha blockers reported the number of participants with dysuria.
AUTHORS' CONCLUSIONS
There is some evidence to suggest the removal of indwelling urethral catheters late at night rather than early in the morning may reduce the number of people who require recatheterisation. It appears that catheter removal after shorter compared to longer durations probably reduces the risk of symptomatic CAUTI and may reduce the risk of dysuria. However, it may lead to more people requiring recatheterisation. The other evidence relating to the risk of symptomatic CAUTI and dysuria is too uncertain to allow us to draw any conclusions. Due to the low certainty of the majority of the evidence presented here, the results of further research are likely to change our findings and to have a further impact on clinical practice. This systematic review has highlighted the need for a standardised set of core outcomes, which should be measured and reported by all future trials comparing strategies for the removal of short-term urinary catheters. Future trials should also study the effects of short-term indwelling urethral catheter removal on non-surgical patients.

Zinner syndrome is a less common birth anomaly of the Wolffian duct consisting of unilateral kidney absence, ipsilateral ejaculatory duct obstruction, and seminal vesicle cyst. A failure of embryogenesis of the ureteric bud between the fourth and 13th week of gestation results in Zinner syndrome. Conservative treatment is recommended for asymptomatic patients, whereas invasive treatment is reserved for symptomatic patients and for those who have failed conservative treatment. In this case report, we describe the non-specific presentation of lower abdominal pain and dysuria, as well as episodes of hematuria and new-onset hypertension, in a male patient, who was otherwise deemed healthy, with no other previous medical or surgical history. An imaging study and laboratory investigations were performed, and the patient was detected to have left renal agenesis and hypointense/hyperintense cysts in the left seminal vesicle of the left kidney. The findings supported the diagnosis of Zinner syndrome. The patient did not present with any symptoms or findings that would suggest infertility at the time of the study. Zinner syndrome is a rare cause of painful micturition and hematuria in males and can be diagnosed using ultrasound (USS), computer tomography (CT), and magnetic resonance imaging (MRI) techniques. Zinner syndrome should be considered as a differential diagnosis in male patients with unilateral renal agenesis and cystic pelvic masses. Patients who are asymptomatic typically undergo conservative treatment and are followed up to prevent infertility. For patients with symptomatic cysts who fail to respond to conservative treatment or whose cysts are larger than 5 cm in diameter, surgical intervention is recommended (open or laparoscopic surgery and ejaculatory duct balloon dilatation).
