Summary
Urinary tract infections caused by ureteric stones are life-threatening, particularly in the elderly. This condition requires intensive care in severe cases and can be fatal, highlighting the need for better epidemiological data.
Area of Science:
- Urology
- Infectious Diseases
- Epidemiology
Background:
- Urinary tract infections (UTIs) secondary to ureteric stones are a serious health concern.
- Few epidemiological studies exist on the incidence and clinical course of obstructive UTIs.
Purpose of the Study:
- To describe the population-based incidence, epidemiology, and clinical outcomes of UTIs caused by ureteric stone obstruction.
- To provide data on a life-threatening condition with limited prior epidemiological reporting.
Main Methods:
- Retrospective cohort study using Swedish National Patient Register and local hospital databases.
- Identified adult patients with International Classification of Disease 10th revision codes for urolithiasis and UTI.
- Analyzed data from 315 patients over two years, excluding those with ongoing treatment, non-significant infection, or no obstruction.
Main Results:
- The incidence of acute obstructive UTI was 11.8 per 100,000 inhabitants annually.
- The median patient age was 68 years, with 56% being women.
- 16% required ICU admission, and 3% died, with deaths attributed to sepsis or delays in treatment.
Conclusions:
- Acute obstructive UTI primarily impacts the elderly population.
- The clinical course is variable, with severe cases necessitating intensive care and carrying a risk of mortality.
- Findings underscore the severity and epidemiological significance of this condition.

01:20Disorders of the Urinary System
The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

01:26Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
01:21Nursing Assessment of the Genitourinary System I: Health History
The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1. Gathering Patient InformationA complete health history includes the patient’s personal,...
01:25Urinary Tract Infection II: Pathophysiology
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
01:30Reservoir of Infection
Infectious diseases arise from intricate interactions between pathogens and their reservoirs. A reservoir of infection refers to the natural habitat where a pathogen lives, grows, and multiplies, serving as a continual source of infection. Reservoirs are broadly classified as either living or nonliving, and each plays a unique role in disease transmission, significantly influencing public health interventions and control strategies.Humans act as reservoirs for a wide array of pathogens,...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
