Summary
Ureteroarterial fistulas (UAFs) are rare but dangerous. Endovascular treatment for UAFs shows better early results and lower mortality compared to open surgery, though long-term data is needed.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Urology
Background:
- Ureteroarterial fistulas (UAFs) are uncommon but life-threatening causes of hematuria.
- Historically managed with open surgery, endovascular techniques offer a less invasive alternative.
Observation:
- A case series of 5 UAFs treated over 10 years is presented.
- Causes included aorta-iliac bypass, endovascular aortic repair, and oncological surgeries.
- Treatments comprised 2 open and 3 endovascular procedures.
Findings:
- Endovascular treatment demonstrated favorable early complication rates and reduced mortality compared to open surgery.
- Despite this, one patient died following endovascular intervention, and two after open surgery.
Implications:
- UAFs are rare, potentially fatal complications requiring careful management.
- Long-term follow-up is crucial to evaluate late complications like prosthetic infection.
- Standardized antibiotic protocols for UAFs are currently lacking, necessitating further research.

539
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...

495
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...

307
The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

547
In managing urinary tract infections (UTIs) in nursing, a comprehensive assessment is essential. Begin by gathering subjective data, such as the patient’s complaints of dysuria (painful urination), urinary frequency, urgency, suprapubic pain, and any lower abdominal discomfort. This information can be complemented by questions regarding previous UTIs, sexual activity, and personal hygiene practices, which can provide insight into risk factors. Objective assessment should focus on signs...
