Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

Cholecystitis

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Urinary 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...

Acute Pyelonephritis II: Diagnostic Studies and Management

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Urinary Tract Infection II: Pathophysiology

Urinary 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...

Urologic Endoscopic Procedure: Cystoscopic Examination

Urologic Endoscopic Procedure: Cystoscopic Examination

Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

BMJ Case Reports

|April 26, 2013

Summary

A rare case shows colovesical fistula, a connection between the colon and bladder, can cause epididymitis (testicular inflammation). Colovesical fistulae are also the primary cause of pneumaturia (air in urine).

Area of Science:

Gastroenterology
Urology
Surgical Case Report

Background:

Diverticular perforation can lead to complications like fistulas.
Colovesical fistulae are abnormal connections between the colon and bladder.
Pneumaturia is a key symptom indicating potential gastrointestinal-urinary tract issues.

Observation:

A 75-year-old male presented with acute left-sided epididymitis and testicular pain.
The patient reported a history of conservatively managed localized diverticular perforation.
He also reported passing air in his urine (pneumaturia).

Findings:

Ultrasound confirmed bacterial epididymitis, treated with IV antibiotics.
CT imaging revealed a colovesical fistula and air within the bladder.

Enterococcus faecalis was identified in urine cultures.

Implications:

This case underscores that epididymitis can be an unusual presenting symptom of a colovesical fistula.
It reinforces that colovesical fistulae are the most common etiology of pneumaturia.
Early diagnosis and surgical intervention (Hartmann's procedure) are crucial for managing such complex cases.
