We report successful percutaneous nephrolithotomy (PCNL) in an 8-week-old, 4.12 kg infant with a combined stone burden of > 2 cm in a solitary kidney. The patient was born with thoracolumbar myelomeningocele and had developed recurrent urinary tract infections. Her size precluded retrograde intrarenal surgery and shockwave lithotripsy would be unlikely to clear the stone burden. Stone analysis revealed hydroxyapatite and carbonate apatite stones, and metabolic work up revealed hypercalciuria for which chlorothiazide was started...

INTRODUCTION: The changing face of current infection phenotypes from planktonic to biofilm type has been developed implicating bacterial biofilms in recurrent infection. To date, no specific medical treatment exists to specifically target biofilms in the human host. Similarly, the identification of a biofilm has relied upon the analysis of tissue samples with electron microscopy or DNA identification with polymerase chain reaction (PCR) and sequencing. Standard culture and sensitivity test is not able to detect a presence of biofilms...

Proteus species, members of the Enterobacteriaceae family, are usually considered commensals in the gut and are most commonly recognized clinically as a cause of urinary tract infections. However, the recent identification of Proteus spp. as potential pathogens in Crohn's disease recurrence after intestinal resection serves as a stimulus to examine their potential role as gut pathogens. Proteus species possess many virulence factors potentially relevant to gastrointestinal pathogenicity, including motility; adherence; the production of urease, hemolysins, and IgA proteases; and the ability to acquire antibiotic resistance...

BACKGROUND: Adenocarcinomas can arise in a variety of circumstances in which intestinal segments have been used for urinary diversions. Whereas ureterosigmoidostomy is the oldest and simplest form of continent urinary diversion it also seems to be the most dangerous in this regard. Herein we present a case of colonic neoplasia complicating a non-functioning ureterosigmoidostomy after 55 years; the longest latent period documented to date. CASE PRESENTATION: A 56-year-old lady born with congenital bladder exystrophy and who had a functional ileal conduit presented to us with a 6 month history of change in bowel habit and rectal bleeding...

Persistent Müllerian duct syndrome is a disorder of sexual development, which features a failure of involution of Müllerian structures. An enlarged prostatic utricle is a kind of Müllerian duct remnant (MDR) with a tubular shaped structure communicating with the prostatic urethra. Treatment is aimed at relieving symptoms when present, preserve fertility and prevent neoplastic degeneration. We describe 3 cases of successful robot assisted-removal of symptomatic MDRs. The first case came to our attention for pseudo-incontinence; the other two for recurrent urinary tract infections...

Extraintestinal pathogenic Escherichia coli (ExPEC) include avian pathogenic E. coli (APEC), neonatal meningitis E. coli (NMEC), and uropathogenic E. coli (UPEC) and are responsible for significant animal and human morbidity and mortality. This study sought to investigate if biofilm formation by ExPEC likely contributes to these losses since biofilms are associated with recurrent urinary tract infections, antibiotic resistance, and bacterial exchange of genetic material. Therefore, the goal of this study was to examine differences in biofilm formation among a collection of ExPEC and to ascertain if there is a relationship between their ability to produce biofilms and their assignment to phylogenetic groups in three media types - M63, diluted TSB, and BHI...

BACKGROUND: Escherichia coli (E. coli) is known to cause urinary tract infection (UTI) and meningitis in neonates, as well as existing as a commensal flora of the human gut. Extended-spectrum β-lactamase (ESBL)-producing E. coli has increased in the community with the spread of CTX-M type ESBL-producing sequence type 131 (ST131)-O25-H30Rx E. coli clone. The role of ESBL-producing E. coli in female genital tract infection has not been elucidated. The clinical and molecular features of E...

Cystic nephroma is an unusual, cystic neoplasm of the kidney and is usually benign. There are two peaks in the incidence of the tumor, with a bimodal distribution presenting in children younger than two years old and in adults. These benign lesions are usually seen in childhood, whose clinical presentation is nonspecific with symptoms such as flank pain, hematuria and urinary tract infection. We aim to report treatment, and follow-up of a 48-year-old female patient with cystic nephroma for whom we performed open partial nephrectomy...

Hemophagoytic lymphohistiocytosis (HLH) is a rare life-threatening disorder caused by overactivation of the immune system, associated with infections, autoimmune disorders, and malignancies. The pathological hallmark of HLH is phagocytosis of blood cells and platelets by activated macrophages and histiocytes. In this report, we describe the onset of HLH in three children, aged 2, 5 and 7 years old, during the treatment of acute focal bacterial nephritis (AFBN) with an antibiotic, piperacillin-tazobactam (PIPC-TAZ)...

In clinical practice, there is a growing need to assess the impact of prior colonization or infection with extended-spectrum β-lactamase-producing Enterobacteriaceae (EPE) on new EPE infections. We have investigated the frequency of, and duration to, a subsequent EPE infection in patients with prior fecal carriage or infection with EPE. Culture data for 3272 EPE-positive patients in Western Sweden during 2004-2014 were evaluated. The median follow-up time was 3.7 years. The first recorded EPE-positive fecal screen, or clinical (urine, blood) culture, and subsequent EPE-positive clinical samples were analyzed, focusing on the first and last recurrence of EPE infection...

Struvite or infection stones are one of the major clinical burdens among urinary tract infection, which occur due to the interaction between microbes and urine mineral components. Numerous urinary tract infection (UTI) causing microbes regulate through biofilm formation for survival from host defense, it is often found difficult in its eradication with simple anti-microbial agents and also the chance of recurrence and resistance development is significantly high. Cranberry consumption and maintenance of urinary tract health have been supported by clinical, epidemiological, and mechanistic studies...
