Urologists are typically faced with clinical situations for which the microbiome may have been a contributing factor. Clinicians have a good understanding regarding the role of bacteria related to issues such as antibiotic resistance; however, they generally have a limited grasp of how the microbiome may relate to urological issues. The largest part of the human microbiome is situated in the gastrointestinal tract, and though this is mostly separated from the urinary system, bacterial dissemination and metabolic output by this community is thought to have a significant influence on urological conditions...

INTRODUCTION: High-grade vesicoureteral reflux (VUR) in children is associated with recurrent urinary tract infection (UTI) and renal damage. Breakthrough UTI despite continuous antibiotic prophylaxis (CAP) during the first years of life is a matter of concern and evokes early intervention. We investigated whether early endoscopic treatment (ET) of VUR grade 4-5 can reduce the risk of UTI recurrence and renal scarring. MATERIALS AND METHODS: This prospective, randomized, controlled, multicentre, 1-year follow-up trial comprised 77 infants, <8 months of age with VUR grade 4-5 (Table) randomized to CAP (n = 39) or ET (with prophylaxis until resolution) (n = 38)...

INTRODUCTION: Children with recurrent urinary tract infections (rUTI) often show no identifiable cause of their infections. Neutrophil gelatinase-associated lipocalin (NGAL) is known to be upregulated within the uroepithelium and kidney of patients with UTI and exhibits a localized bacteriostatic effect through iron chelation. We hypothesize that some patients with rUTI without an identifiable cause of their recurrent infections have locally deficient NGAL production. We therefore explored whether a lack of NGAL production may be a factor in the pathogenesis of rUTI...

Emphysematous pyelonephritis is a rare infection characterized by necrosis and gas accumulation in the renal parenchyma, adjacent tissues, and/or urinary collecting system. This entity is rarely reported in transplanted kidneys. Computed tomography imaging is necessary for diagnosis and risk classification. The authors described the case of a 58-year-old man who underwent a kidney transplant and presented sepsis from a urinary tract infection. An abdominal tomography showed some characteristics of emphysematous pyelonephritis associated with an abscess...

Erosion of surgical materials into the adjacent organs following surgical procedures is a rare complication. Migrations of these surgical materials into the urinary tract like pelvicalyceal system, ureter and bladder have been reported following various urological procedures. We present a case of migrated Hem-o-Lok clips into the ureter following a laparoscopic partial nephrectomy for angiomyolipoma of the left kidney presented with recurrent urinary tract infection. The case was managed with ureteroscopic removal of clips...

Symptomatic candiduria often occurs in patients with indwelling bladder catheters or immunocompromised host. Isolation of Candida in urine in high-risk patients should primarily be considered as a marker for candidemia. Hematological and genitourinary malignancies are one of the main risk factors associated with Candida urinary tract infections (CUTI). Fluconazole is a choice for initial treatment of CUTI, but it is fluctuate depending on the patient's condition including renal failure, site of urinary infection and Candida species...

Thrombotic microangiopathy (TMA) is a well-recognised complication following transplantation, often due to an underlying genetic predisposition, medications or rejection. The use of eculizumab in these settings has been previously described, but its role still remains to be clarified. A 45-year-old man, with a history of type 1 diabetes mellitus and subsequent end-stage kidney failure, presented for a simultaneous pancreas-kidney transplant. Immunologically, he was well matched with the donor, and he received standard induction immunosuppression including tacrolimus...

Urinary tract infections (UTI) are the most common bacterial infections in children. The symptoms are not very specific and range from abdominal pain, poor feeding to nocturnal urinary incontinence. The technique of collecting urine plays an important role for securing the diagnosis. The best way to obtain urine in non-toilet-trained children is catheterization or suprapubic bladder aspiration. In toilet-trained children midstream urine is an acceptable alternative after cleaning the foreskin or labia. In the case of an infection a prompt empirical antibiotic therapy is necessary to reduce the risk of parenchymal scarring of the kidneys...

The aim of this supplement is to discuss the important role of the kidney in glucose homeostasis. It produces glucose via gluconeogenesis, it filters glucose from the blood, and reabsorbs the filtered glucose in the proximal tubule, mainly via the sodium-glucose cotransporter-2 (SGLT-2). SGLT-2 is paradoxically upregulated in individuals with type 2 diabetes (T2D), which results in increased glucose reabsorption and hyperglycemia. This core defect in the pathophysiology of T2D provides the rationale for the use of SGLT-2 inhibitors to increase urinary glucose excretion and reduce hyperglycemia in an insulin-independent manner...

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary form of kidney disease. Clinical data on this multisystem disorder are scarce from developing countries. We conducted a prospective observational study of the clinical profile of ADPKD patients at a single center over a period of six years. A total of 208 patients were studied. Majority were male (60.6%) and the mean age was 45.8 ± 14.5 years. About 61.5% had early stage (Stages 1-3) of chronic kidney disease (CKD) and 38.5% had advanced CKD (Stages 4 and 5)...

UTI may involve the lower or upper urinary tract and may be uncomplicated or complicated. The emphasis of this chapter is uncomplicated UTI. The diagnosis of uncomplicated cystitis (bladder infection) and pyelonephritis (kidney infection) is usually easily made based on the clinical presentation, whereas the diagnosis in patients with complicated UTI is often more complex. Thus uncomplicated cystitis is usually manifested by dysuria, frequency and/or urgency without fever, and pyelonephritis is usually manifested by fever and back pain/costovertebral angle tenderness...

BACKGROUND: Community-onset urinary tract infections (CoUTIs) are the most common bacterial infections, and a decline in antibiotic susceptibility causes many clinical challenges. Adequate empiric antibiotic treatment can decrease unnecessary hospital stays and complications, while reducing the antimicrobial resistance progression. METHODS: From October 2014 to April 2015, we retrospectively enrolled patients who were at least 18 years old and required hospitalization for CoUTIs...

AIM: It was believed that neurogenic bladder (NB) might be a risk factor of chronic kidney disease (CKD). However, data are limited regarding the real incidence or risk of CKD in NB. In addition, serum creatinine (sCr), a classical marker of renal function, is not reliable in NB patients because they present muscle wasting due to disuse or denervation. The aim of the study was to estimate the prevalence of CKD in NB patients using serum Cystatin-C. Secondly, we aimed to identify the risk factors for CKD development in NB...

Pseudomonas aeruginosa is a multifaceted pathogen causing a variety of biofilm-mediated infections including catheter-associated urinary tract infections (CAUTIs). High prevalence of CAUTIs in hospitals, their clinical manifestations like urethritis, cystitis, pyelonephritis, meningitis, urosepsis, death; and economic challenges underscore the need for management of these infections. Biomaterial modification of urinary catheters with dual drugs seems an interesting approach to combat CAUTIs by inhibiting biofilm...
