sterile pyuria

BACKGROUND: Pre-eclampsia, an important cause of maternal and perinatal morbidity and mortality world-wide has been linked to subclinical infections, with maternal infection and inflammation postulated in its aetio-pathogenesis including asymptomatic bacteriuria which is common in pregnancy. The Obejctive of the study is to determine the relationship of asymptomatic bacteriuria as a risk factor for pre-eclampsia. METHODOLOGY: A hospital-based case-control study among 28 pre-eclamptic pregnant women (cases) and 56 healthy pregnant women (controls) at gestational age of at least 28 weeks at the University College Hospital, Ibadan, between January 2019 and August 2019...

INTRODUCTION AND IMPORTANCE: It is rare for calcium oxalate renal stone, presented mainly in sterile urine, to result in urinary tract infection. The stone-related infection could develop spondylodiscitis, causing neurological deficits. To date, there are no reports about calcium oxalate partial staghorn stone and spondylodiscitis. CASE PRESENTATION: A 62-year-old male suffered from haematuria, fever, and flank pain. He came to the urology outpatient department, where acute pyelonephritis was diagnosed, and a left partial staghorn stone was seen on computed tomography...

Kawasaki illness is an inflammatory condition of small- to medium-sized vessels that primarily affects children. It affects the lymph nodes, skin, mucous membranes, and heart, especially the coronary arteries. Patients who lack the comprehensive clinical manifestations of classic Kawasaki disease (KD) are typically evaluated for incomplete KD. Such patients have persistent fever and lack one or more characteristic clinical signs. Here, we present a case of a 16-month-old baby presented with fever for nine days, excessive crying and irritability for four days, and refusal to feed for one day with pallor and developed lip cracking, mucositis, bilateral edema, and redness in the palms and soles followed by periungual desquamation...

Tuberculosis (TB) infection of the genitourinary tract (GU TB) is rare in renal transplant recipients, with only a few published case series. GU TB is difficult to diagnose with or without immunosuppression but must always be suspected in any patient with unexplained sterile pyuria. As GU TB is associated with graft rejection, prompt diagnosis and treatment are vital. Treatment is challenging, as rifampicin, the most effective drug used to treat tuberculosis, is a significant inducer of cytochrome P-450 3A metabolism, with the potential to cause significant reductions in the serum levels of calcineurin inhibitors...

Background: Kawasaki disease (KD) is an acute systemic vasculitis and is becoming the leading cause of acquired cardiac disease in Children. Sterile pyuria is a known complication of KD. However, its associations with the inflammatory reaction severity, IVIG resistance as well as coronary artery lesions (CALs) in KD remain elusive. Aims: We aimed to analyze the clinical profiles of sterile pyuria in KD, to determine whether sterile pyuria is an indicator of the disease severity in patients with KD, and to assess the associations between sterile pyuria and IVIG resistance as well as CALs...

OBJECTIVE: Postoperative urinary tract infection is the most common complication of retrograde intrarenal surgery, and no consensus has been obtained that would reveal exact reasons yet. It was aimed to determine the possible factors, especially preoperative urinalysis, of postoperative urinary tract infection after retrograde intrarenal surgery. MATERIAL AND METHODS: Patients who underwent retrograde intrarenal surgery in our clinic between 2013 and 2019 were retrospectively screened...

INTRODUCTION: World Health Organization (WHO) is encouraging reporting of children with Multisystem Inflammatory Syndrome (MIS-C) associated with SARS-CoV-2 infection for better understanding and management of the disease. METHODOLOGY: This retrospective study included the first 15 pediatrics patient with a confirmed diagnosis of MIS-C associated with SARS-CoV-2 infection in the state of Qatar. We studied and analyzed their demographic data, clinical manifestations, laboratory tests, treatment, and outcome...

Epstein-Barr virus (EBV) infection with associated acute acalculous cholecystitis (AAC) has been reported in 18 pediatric patients. Our case is that of a seven-year-old girl with acute EBV infection and associated AAC.

BACKGROUND: This study aimed to evaluate the association of asymptomatic pyuria before ureterorenoscopic lithotripsy (URSL) with postoperative febrile urinary tract infection (UTI). METHODS: This observational case-control study identified the patients undergoing URSL for ureteral stones between May 2011 and October 2015. The included patients were classified into two groups: the asymptomatic pyuria group (6-50 white blood cells [WBCs]/high-power field [HPF]) and the non-pyuria group (≤ 5 WBCs/HPF)...

BACKGROUND: Nowadays, most studies of tuberculous epididymo-orchitis (TBEO) are case reports or small sample cohort series. Our study is aimed to present the largest series of TBEO with our management experiences and long-term follow-up outcomes. METHODS: Patients diagnosed with TBEO after surgical procedures at Department of Urology, West China Hospital from 2008 to 2019 were included. All clinical features, auxiliary examination results, treatment and histopathological findings were extracted if available...

PURPOSE: To report our management of preoperative polymicrobial urine culture and to determine its correlation with the risk of postoperative urinary tract infection (UTI). PATIENTS AND METHODS: We retrospectively identified all patients with preoperative polymicrobial urine culture in our center between January 2017 and October 2019. Preoperative urine cultures were collected 5 to 8 days before the surgery. No antibiotic prophylaxis was administered preoperatively in the absence of pyuria...

Chronic kidney disease (CKD) is considered a major health problem, which poses a burden for health care systems worldwide. It has been estimated that 10% of the population worldwide have CKD; however, most of the cases are undiagnosed. If left untreated, CKD could lead to kidney failure, which highlights the importance of early diagnosis and treatment. Pyuria has been reported in CKD patients, and could be the result of several comorbidities, such as diabetes, or urinary tract infections (UTIs). A few studies have shown that pyuria is associated with the late stages of CKD...

INTRODUCTION: Urethral catheterization (CATH) and suprapubic aspiration (SA) are reliable methods of collecting urine for the diagnosis of urinary tract infections (UTIs), but both are invasive and difficult. Therefore, urine collection through a sterile urine bag (SUB) is commonly used for UTI screening. However, when pyuria is found in SUB specimens, it is difficult to interpret whether this result is true or false. OBJECTIVE: We aimed to determine the diagnostic performance of the urinary NAG/Cr ratio in detecting true pyuria in SUB specimens for children with suspected UTIs...

A 74-year-old man with diabetic nephropathy undergoing dialysis after total knee arthroplasty presented to our hospital with dyspnea and abnormal behavior such as wearing his pants on his head. The patient was in shock with ventricular tachycardia. Urine and blood cultures showed MAM with sterile pyuria. We administered amikacin and imipenem cilastatin, but repeated cultures were persistently positive. Although we initially chose not to administer azithromycin because of a higher risk of fatal arrhythmia, we had no choice but to administer azithromycin because of treatment failure...

Sterile pyuria is a common finding in pediatric patients. Literature describing the diagnoses as well as clinical characteristics of children with sterile pyuria is lacking. This review was performed to establish an evidence-based approach to the differential diagnosis by way of an extensive literature search. The definition of pyuria is inconsistent. The various causes of pediatric sterile pyuria identified were classified as either Infectious or Non-Infectious. Sub-categories of Infectious causes include: Viral Infection, Bacterial Infection, Other Infections (tuberculosis, fungal, parasitic), Sexually Transmitted Infections, Recent Antibiotic Therapy...

Bofutsushosan (BTS), one of many traditional Japanese medicines (Kampo medicines) is attracting attention for obesity and metabolic syndrome. We report allergic cystitis caused by 8-year BTS usage in a 70-year-old female. The patient presented with micturition pain with sterile pyuria over a 3-month period. Cystoscopy showed diffuse urothelial erythema and edema. Urine cytology specimens showed increased eosinophilic cells. By discontinuing BTS, the cystitis symptoms disappeared after 4 days, and urinalysis normalized...
