Urinary catheter use is prevalent in health care settings, and polymicrobial colonization by urease-positive organisms, such as Proteus mirabilis and Providencia stuartii, commonly occurs with long-term catheterization. We previously demonstrated that coinfection with P. mirabilis and P. stuartii increased overall urease activity in vitro and disease severity in a model of urinary tract infection (UTI). In this study, we expanded these findings to a murine model of catheter-associated UTI (CAUTI), delineated the contribution of enhanced urease activity to coinfection pathogenesis, and screened for enhanced urease activity with other common CAUTI pathogens...

BACKGROUND: Despite the multiple benefits of maintaining residual urine volume (RUV) in hemodialysis (HD), there is limited data from Sub-Saharan Africa. The aim of this study was to assess the impact of RUV decline on the survival of HD patients. METHODS: In a retrospective cohort study, 250 consecutive chronic HD patients (mean age 52.5 years; 68.8% male, median HD duration 6 months) from two hospitals in the city of Kinshasa were studied, between January 2007 and July 2013...

Studies have shown that calves fed milk replacers (MR) with crude protein (CP) concentrations greater than 20%, as typically found in conventional MR, have higher dry matter intakes (DMI) and greater average daily gains (ADG) but consume less starter, which can lead to stress during weaning and reduced rumen development. The greater amount of CP being fed to preweaned calves may alter their nitrogen (N) balance, and excess N may be excreted in the urine. The objective of this study was to determine N utilization in preweaned calves fed diets varying in the amount of CP and MR fed...

BACKGROUND: A urostomy with an ileum conduit or a skin fistula leads to a high infection risk for the kidneys and the ureter of the patient. Therefore, the prevention of retrograde colonization of the artificial drain (splint) with e. g. contaminated urine is the most important objective of infection prevention measurements. We performed an in vitro experiment to determine the migration speed of clinically relevant bacteria in a commercially available splint catheter system. METHODS: The migration speed of bacteria in commonly used splint catheters was determined in a practice-like in vitro model...

BACKGROUND: An alternative treatment for obstructive and refluxing obstructive megaureter with ureterovesical junction maintenance through laparoscopy is proposed. MATERIAL AND METHODS: The series consists of 8 cases, all of them studied because of prenatal hydronephrosis or febrile urinary tract infection. Seven were diagnosed with obstructive megaureter and one with obstructive refluxing megaureter. The procedure consisted in incising the stenotic portion of the ureter longitudinally and maintaining its posterior wall attached to the bladder, the anterior wall of the ureter was anastomosed transversally to the bladder mucosa in order to liberate the obstruction...

Urinary tract infection (UTI) is one of the most common bacterial infections, and the incidence in women is much higher than in men. The diagnosis of a UTI can be made based on a combination of symptoms and a positive urine analysis or culture. Most UTIs are uncomplicated UTIs, defined as cystitis in a woman who is not pregnant, is not immunocompromised, has no anatomical and functional abnormalities of the urogenital tract, and does not exhibit signs of tissue invasion and systemic infection. All UTIs that are not uncomplicated are considered to be complicated UTIs...

Stripped of any sense of comfort or dignity on that hospital bed, my 84-year-old father, my best friend, was enduring raw, intrusive medical procedures against his own wish; defenseless, vulnerable, agonized. A feeding tube went in through his nose; catheter tubes drained urine out of his bladder; a suction pump drew out fluid from his airway. A needle jammed into the central line, making it impossible for him to turn his head. Dialysis took over the job of his kidneys. But no painkillers were given for fear his weak heart could not take more chemicals...

A 55-year-old woman was referred to our hospital with dysuria. We were unable to catheterize her using a nelaton catheter because of a urethral stricture, resulting in a large residual urine volume on ultrasonography. The circumference of the periurethral tissue was also thickened and the entire length of the urethra was stenotic, without apparent cause, on magnetic resonance imaging. Biopsy did not reveal malignancy. The pathological diagnosis of the periurethral tissue was simply fibrosis, and there was no definitive diagnosis...

The management of ureteral obstruction of malignant origin or complicated benign obstruction continues to be a challenge for the urological community. In this sense, the use of metallic stents could be considered a useful alternative to the conventional drainage techniques, because it accomplishes the resolution of obstruction in a single procedure, without external diversions and without the adverse effects of current diversions. Another important advantage they offer is that they do not need replacement as frequently as double J catheters or nephrostomy tubes require...
