BACKGROUND
Women with urinary tract infections (UTIs) often present with urinary complaints such as frequency of micturition, dysuria, foul-smelling urine and other non-specific symptoms like fever. Physicians may order urine microscopy to guide empirical antibiotic prescription. However, the performance of this approach has not been assessed.
OBJECTIVES
This study aimed to determine the accuracy of UTI symptoms and urine microscopy associated with culture-positive UTI in Asian women.
METHODS
A cross-sectional study of adult women who presented with UTI-related symptoms was conducted at three public primary care clinics in Singapore. Demographic data and information on their symptoms were collected, followed by urine microscopy and culture to diagnose UTI. The sensitivity, specificity, positive (PPV), negative predictive values (NPV), accuracy (ACC) and area under curve (AUC) of combinations of symptom and urine investigations were analysed in association with culture-positive UTI, which was regarded as a benchmark.
RESULTS
Data on 564 women (73.9% Chinese, 11.5% Malay, 8.2% Indian) were analysed, of which 259 (45.9%) had culture-positive UTI. Frequency and foul-smelling urine, pyuria (WBC ≥10/hpf) and semi-quantitative bacterial count (≥2+) were significantly associated with positive urine culture. The ACC and AUC for single or multiple urinary and/or general symptoms were low. Urine pyuria (minimally >10/hpf) alone or in combination with symptoms and/or semi-quantitative bacterial count achieved high sensitivity (>85%) and PPV, NPV, ACC and AUC of >70%.
CONCLUSION
Urinary symptoms have limited accuracy in diagnosing culture-positive UTI. Concurrent urine microscopy showing presence of pyuria and/or bacterial count increased the diagnostic accuracy of culture-positive UTI.

OBJECTIVE
The utility of the urinalysis as a potential marker to diagnose urinary tract infection (UTI) in patients with neurogenic bladder is controversial. We assessed the baseline urine characteristics and intraindividual variance of pyuria in a cohort of asymptomatic children with neurogenic bladder followed longitudinally.
STUDY DESIGN
A cohort of 54 children with neurogenic bladder was followed from 2004 to 2015 at a single institution's multidisciplinary clinic. Urine data obtained from 529 routine urology visits were reviewed. Urine obtained within 2 weeks before or after treatment for UTI were excluded. Bladder surgery was defined as any operation that altered the bladder as a closed or sterile system. The effects of age, gender, catheterization, and bladder surgery on pyuria were evaluated using mixed-model regression analysis.
RESULTS
Fifty patients with 305 urine samples had a mean length of follow-up of 3.2 years. Only 16/50 patients (32%) never had pyuria, and these patients had shorter follow-up compared with the group who ever had pyuria (≥5 white blood cells per high powered field) (1.7 vs. 3.8 years; P = 0.008). Catheterization was associated with a 15% increase in pyuria (P = 0.21). Surgery was associated with a 120% increase in pyuria (P < 0.001). The test-to-test variance of pyuria within an individual was consistently greater than between individuals (P < 0.001).
CONCLUSIONS
Bladder surgery is associated with significant increases in pyuria among children with neurogenic bladder. The substantial test-to-test variation in pyuria in asymptomatic individuals indicates the low reliability of pyuria, when positive, as a marker for UTI in neurogenic bladder and the need to search for either methods to reduce this variability or alternative biomarkers of UTI in this population.

Clinical Trial
To prospectively assess early post-transurethral prostate surgery (TUPS) urinalysis changes and bacteriuria with its clinical relevance. Patients with benign prostate obstruction enrolled for TUPS were prospectively assessed. Patients were assessed at 2, 4, 8, 12, and 24 weeks postoperatively by the dysuria-visual-analogue-scale (DVAS), international prostate symptom scores (IPSS)-quality of life, uroflow, and postvoid residual. Routine urinalysis was performed before discharge and at all visits. Midstream urine culture (MSUC) was performed before discharge, and 4 and 12 weeks postoperatively. At final analysis, 152 patients were evaluable. Significant pyuria was reported in 52%, 96.1%, 94.1%, 71.7%, 78.9%, and 52.5% in, before discharge, 2-, 4-, 8-, 12-, and 24-week urinalysis postoperative, respectively. The mean time to nonsignificant pyuria (95% confidence interval [CI]) was 19.1 (17.5-20.7), 20.1 (17.3-22.9), 15.8 (12.8-18.8), and 14 (10.3-17.8) weeks after prostate resection, vaporization, enucleation, and incision, respectively ( = 0.03). Regardless the TUPS technique, half of patients had significant pyuria at 24 weeks postoperative. MSUC was positive in 37/152 (24.3%), 3/152 (2%), 23/152 (15.1%), and 5/152 (3.3%) preoperatively, before discharge, and 4 and 12 weeks postoperative, respectively. Only positive preoperative urine leukocyte esterase independently predicted positive 4-week MSUC (odds ratio 3.8, 95% CI 1.3-11.1, = 0.013). No significant correlation was found between IPSS or DVAS and positive MSUC, nor between IPSS and postoperative pyuria at different follow-up points ( > 0.05). However, the degree of postoperative dysuria was significantly correlated with postoperative pyuria count by urinalysis at 2 weeks ( = 0.69, = 0.03), 8 weeks ( = 0.26, = 0.001), and 12 weeks ( = 0.23, = 0.004). There is a persistent but gradually declining pyuria and microhematuria following TUPS up to 6 months postoperative. An earlier resolution was noted following prostate incision and enucleation. While routine urine analysis screening in these months would be of no clear clinical value, a routine urine culture would be of a reasonable significance at 1 month postoperatively.

INTRODUCTION
Retrograde pyelography (RP) is performed for examination of upper urinary tract cancers and hydronephrosis. Although urinary tract infections (UTI) are known to be complicated by the examination, there are few reports on the frequency of occurrence and prophylactic antibiotics.
METHODS
The incidence of UTI and febrile UTI (f-UTI) and patient background information were compared in 388 patients who underwent RP at our hospital from January 2018 to December 2022. We also examined the administration of pre-RP antibiotics.
RESULTS
Of the 388 patients who underwent RP, 27 (6.9%) had UTI and 17 (4.4%) had f-UTI. Of the 27 UTI cases, 25 (92.6%) were pyelonephritis; 20 (74.0%) were hospitalized and 2 (7.4%) presented with septic shock and were managed in the intensive care unit. When comparing the background of patients with UTI, no significant differences were found in the present study, but when limited to the 17 cases of f-UTI, the presence of hydronephrosis before RP and not prescribing antibiotics before RP were associated with significantly higher incidence of f-UTI (p = 0.019, p = 0.036, respectively). Especially for patients without pyuria and bacteriuria before RP, prescribing antibiotics before RP resulted in 0 cases of f-UTI (p = 0.020).
CONCLUSION
This retrospective study showed that the presence of hydronephrosis before RP and not prescribing prophylactic antibiotics before RP are risk factors for f-UTI.

Review
BACKGROUND
It is unclear whether antibiotics impact delirium outcomes in older adults with pyuria or bacteriuria in the absence of systemic signs of infection or genitourinary symptoms.
METHODS
We registered our systematic review protocol with PROSPERO (CRD42023418091). We searched the Medline and Embase databases from inception until April 2023 for studies investigating the impact of antimicrobial treatment on the duration and severity of delirium in older adults (≥60 years) with pyuria (white blood cells detected on urinalysis or dipstick) or bacteriuria (bacteria growing on urine culture) and without systemic signs of infection (temperature > 37.9C [>100.2F] or 1.5C [2.4F] increase above baseline temperature, and/or hemodynamic instability) or genitourinary symptoms (acute dysuria or new/worsening urinary symptoms). Two reviewers independently screened search results, abstracted data, and appraised the risk of bias. Full-text randomized controlled trials (RCTs) and observational study designs were included without restriction on study language, duration, or year of publication.
RESULTS
We screened 984 citations and included 4 studies comprising 652 older adults (mean age was 84.6 years and 63.5% were women). The four studies were published between 1996 and 2022, and included one RCT, two prospective observational cohort studies, and one retrospective chart review. None of the four studies demonstrated a significant effect of antibiotics on delirium outcomes, with two studies reported a worsening of outcomes among adults who received antibiotics. The three observational studies included had a moderate or serious overall risk of bias, while the one RCT had a high overall risk of bias.
CONCLUSIONS
Our systematic review found no evidence that treatment with antibiotics is associated with improved delirium outcomes in older adults with pyuria or bacteriuria and without systemic signs of infection or genitourinary symptoms. Overall, the evidence was limited, largely observational, and had substantial risk of bias.

PURPOSE
To evaluate if preoperative sterile pyuria can be a prognostic factor for intravesical recurrence (IVR) and overall survival (OS)in patients with upper tract urothelial carcinoma (UTUC) undergoing surgery.
MATERIALS AND METHODS
We retrospectively reviewed the medical records of patients who were diagnosed with UTUC from October 2003 to December 2016 at Korea University Medical Center. Sterile pyuria was defined as urine containing five or more white blood cells per high-power field in the absence of bacteria in urine culture. We used a stepwise multivariable Cox proportional hazards model to assess the independent effects of the prognostic factors for IVR and OS.
RESULTS
We investigated a total of 176 patients who were diagnosed with UTUC. Among them, 91 (51.7%) patients had preoperative sterile pyuria. There were no significant differences in the baseline characteristics between the pyuria and non-pyuria groups concerning tumor grade, T stage, tumor multiplicity, and recurrence history. However, there was a significant difference in the IVR between the two groups. In the multivariable analysis, preoperative sterile pyuria, diabetes mellitus, high-grade tumor, and lymphovascular invasion were revealed as independent risk factors for IVR, and only lymphovascular invasion was identified as an independent risk factor for OS.
CONCLUSIONS
Preoperative sterile pyuria is significantly associated with IVR in patients with UTUC undergoing surgery, but it is not associated with OS. Furthermore, diabetes mellitus, high-grade tumor, and lymphovascular invasion are also independent prognostic factors for these patients.

INTRODUCTION
The effect of repeated cystoscopy on bladder cancer (BC) patient anxiety and feelings is rarely evaluated.
AIM
To compare the difference of patients' anxiety and subjective feelings caused by different cystoscopes.
MATERIAL AND METHODS
We prospectively included 192 BC patients who accepted regular cystoscopy follow-up after transurethral resection of bladder tumor (TURBT): 93 in the flexible group and 99 in the rigid group. The method of anesthesia and the order of examinations were consistent between different groups. We analyzed the anxiety level before cystoscopy, the maximum pain during the examination and the change of lower urinary tract symptoms (LUTS) before and after cystoscopy. Meanwhile, we analyzed the rate of gross hematuria and pyuria after cystoscopy. The anxiety and pain levels were evaluated by the Amsterdam Preoperative Anxiety and Information Scale (APAIS) and visual analogue scale (VAS). LUTS was reflected by the Core Lower Urinary Tract Symptom Score (CLSS). We distinguished gender during analysis.
RESULTS
The median APAIS score of male patients undergoing flexible or rigid cystoscopy was 8 vs. 12 (p < 0.01), and this result for females was 8 vs. 9 (p = 0.048). The median pain scores for men in the two groups was 1 vs. 2 (p < 0.01), respectively, and this outcome in female patients was 0 vs. 1 (p < 0.01). Patients in the rigid group had more CLSS change (0 vs. 1, p < 0.01). There was no difference in pyuria or gross hematuria rate after examination. Analysis in respective groups showed that men have more severe pain than women, 1 vs. 0 (p = 0.001) in the flexible group and 2 vs. 1 (p = 0.009) in the rigid group.
CONCLUSIONS
A flexible cystoscope can improve anxiety and subjective feelings of BC patients during cystoscopy follow-up.

IMPORTANCE
Guidelines recommend withholding antibiotics in asymptomatic bacteriuria (ASB), including among patients with altered mental status (AMS) and no systemic signs of infection. However, ASB treatment remains common.
OBJECTIVES
To determine prevalence and factors associated with bacteremia from a presumed urinary source in inpatients with ASB with or without AMS and estimate antibiotics avoided if a 2% risk of bacteremia were used as a threshold to prompt empiric antibiotic treatment of ASB.
DESIGN, SETTING, AND PARTICIPANTS
This cohort study assessed patients hospitalized to nonintensive care with ASB (no immune compromise or concomitant infections) in 68 Michigan hospitals from July 1, 2017, to June 30, 2022. Data were analyzed from August 2022 to January 2023.
MAIN OUTCOMES AND MEASURES
The primary outcome was prevalence of bacteremia from a presumed urinary source (ie, positive blood culture with matching organisms within 3 days of urine culture). To determine factors associated with bacteremia, we used multivariable logistic regression models. We estimated each patient's risk of bacteremia and determined what percentage of patients empirically treated with antibiotics had less than 2% estimated risk of bacteremia.
RESULTS
Of 11 590 hospitalized patients with ASB (median [IQR] age, 78.2 [67.7-86.6] years; 8595 female patients [74.2%]; 2235 African American or Black patients [19.3%], 184 Hispanic patients [1.6%], and 8897 White patients [76.8%]), 8364 (72.2%) received antimicrobial treatment for UTI, and 161 (1.4%) had bacteremia from a presumed urinary source. Only 17 of 2126 patients with AMS but no systemic signs of infection (0.7%) developed bacteremia. On multivariable analysis, male sex (adjusted odds ratio [aOR], 1.45; 95% CI, 1.02-2.05), hypotension (aOR, 1.86; 95% CI, 1.18-2.93), 2 or more systemic inflammatory response criteria (aOR, 1.72; 95% CI, 1.21-2.46), urinary retention (aOR, 1.87; 95% CI, 1.18-2.96), fatigue (aOR, 1.53; 95% CI, 1.08-2.17), log of serum leukocytosis (aOR, 3.38; 95% CI, 2.48-4.61), and pyuria (aOR, 3.31; 95% CI, 2.10-5.21) were associated with bacteremia. No single factor was associated with more than 2% risk of bacteremia. If 2% or higher risk of bacteremia were used as a cutoff for empiric antibiotics, antibiotic exposure would have been avoided in 78.4% (6323 of 8064) of empirically treated patients with low risk of bacteremia.
CONCLUSIONS AND RELEVANCE
In patients with ASB, bacteremia from a presumed urinary source was rare, occurring in less than 1% of patients with AMS. A personalized, risk-based approach to empiric therapy could decrease unnecessary ASB treatment.

Acute focal bacterial nephritis (AFBN) is a localized bacterial infection of the kidneys presenting as an inflammatory mass that can develop into renal abscess. The current reports on AFBN mostly are among children and rarely described in adults. This study was aimed to analyze the clinical features of AFBN in adults and make a review for the disease to give the clinicians some clues to suspect and recognize it in adults. From January 2014 to December 2019, AFBN was diagnosed by contrast-enhanced computed tomography (CT) in 238 adults at the Department of Nephrology, the Second Hospital of Hebei Medical University, Shijiazhuang, China. We reviewed the clinical records of these patients and asked them about their post-discharge status via telephone follow-up. Of all the patients, 195 were female and 43 were male, the median age were 46.87 years. 86.13% presented with fever, 55.89% presented with lower urinary tract symptoms and 97.9% presented with pyuria. In renal ultrasonography, abdominal findings were seen only 22.69% patients. E.coli accounted for 74.73% of the isolated pathogen. After 4 weeks of treatment, the patients had no recurrence of symptoms. We recommend that when a patient presents clinically with acute pyelonephritis, but the fever persist longer after antimicrobial treatment (≥ 4 days in our study), AFBN should be suspected. For the diagnosis, contrast-enhanced CT is the "gold standard", magnetic resonance imaging (MRI) may be a good option, but the ultrasonography is probably not satisfied. 3-4 weeks of antibiotic therapy may be appropriate for AFBN in adults.

Introduction COVID-19 pandemic has spread across the globe in the last two years and COVID-19 pneumonia is its typical presentation. Coronavirus (SARS-CoV-2) has the potential to affect extrapulmonary sites like the involvement of the urinary tract and male genital organs. Objectives This single institutional retrospective observational study aimed to study the effects of COVID-19 on the lower urinary tract (LUT) and male genital system. Methods COVID-19 effect on the genitourinary tract was studied in a retrospective observational setting in a tertiary care setting from March 2020 to December 2021 consisting of 110 patients. After informed consent from patients, retrospective data collection was included in a repository. Presenting features related to the genitourinary tract were noted and basic biochemical profiles like CBC, RFT, LFT, urine analysis, and urine culture for bacterial sensitivity were performed in all the patients affected by COVID-19. High-resolution ultrasound was sparingly used according to the clinical presentation of these COVID-19 patients. Results A total of 110 patients 95 males and 15 females were included in this study. De novo LUT symptoms were present in 10 (9.09%) patients and acute worsening of these was seen in three patients. Scrotal discomfort was the most common symptom among men found in five (5.26%) patients and frequency of urine was the overall most common symptom found in 13 (12.38%) patients also having two female patients. Among biochemical findings, microscopic hematuria in 68 (61.81%), pyuria in 72 (65.45%), and raised blood urea were observed in 41 (37.27%) patients with COVID-19. Ultrasound findings revealed acute epididymal-orchitis in 3 (3.15 %) and acute orchitis/epididymitis in one (1.05%) case, respectively. Conclusions COVID-19 patients do have the chance of developing the involvement of the urinary tract and male genital system and the clinicians should be aware of this so that they can manage these patients accordingly.
