An Orthotopic Model of Murine Bladder Cancer
Published on: February 6, 2011
Summary
Asymptomatic microhematuria evaluation in 200 patients revealed significant urologic lesions in 20%, including genitourinary cancers. Urologic examination is crucial for patients over 40 with this condition.
Area of Science:
- Urology
- Nephrology
Background:
- Microhematuria, the presence of blood in urine not visible to the naked eye, can indicate serious underlying conditions.
- Asymptomatic microhematuria, particularly in older adults, warrants thorough investigation to rule out significant pathology.
Purpose of the Study:
- To determine the causes (etiology) of asymptomatic microhematuria.
- To assess the diagnostic yield of complete urologic examinations in patients with asymptomatic microhematuria.
- To evaluate the long-term outcomes of patients with asymptomatic microhematuria.
Main Methods:
- Review of 200 consecutive patients with asymptomatic microhematuria.
- Complete urologic examination for all participants.
- Two-year follow-up to assess outcomes and identify missed diagnoses.
Main Results:
- Significant urologic lesions were identified in 20% of patients.
- Genitourinary malignant neoplasms were found in 13% of patients with urologic lesions.
- No identifiable urologic lesion was found in 19% of the investigated patients.
- The majority of patients were between 50 and 59 years old.
Conclusions:
- Complete urologic examination is justified for patients with asymptomatic microhematuria, especially those over 40.
- Current diagnostic tools have improved the ability to diagnose the causes of microhematuria.
- A significant proportion of patients with asymptomatic microhematuria have underlying urologic pathology, including cancer.

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...
01:26Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
01:29Urine Studies I: Urinalysis
Urinalysis is a widely used diagnostic test that analyzes urine's physical, chemical, and microscopic characteristics. Healthcare providers use it to detect and monitor various health conditions, including renal disease, urinary tract infections (UTIs), diabetes, and metabolic or systemic disorders.Components of UrinalysisUrinalysis consists of three primary components: physical, chemical, and microscopic examination. Each provides unique insights into the urine sample and, by extension, the...
01:24Serum Studies: Renal Function Tests
Renal function tests are crucial for assessing kidney health, monitoring disease progression, and evaluating the kidneys' efficiency in waste elimination, fluid balance, and electrolyte regulation. These tests offer critical insights into kidney function, even though routine measurements may appear normal until there is a significant decline in the glomerular filtration rate or GFR. Typically, signs of kidney impairment only become evident when the GFR falls to about 50% of its normal level.
01:30Acute Kidney Injury IV: Diagnostic Studies and Prevention
Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
