Summary
Ascorbic acid supplementation significantly reduced double J ureteric stent encrustations. Lack of this supplement, male gender, and longer stent duration were key risk factors for encrustation.
Area of Science:
- Urology
- Nephrology
- Medical Chemistry
Background:
- Double J (DJ) ureteric stent encrustation is a common complication.
- Encrustation can make stent removal difficult and lead to adverse events.
Purpose of the Study:
- To evaluate the efficacy of ascorbic acid supplementation in preventing DJ ureteric stent encrustations.
- To identify risk factors associated with DJ stent encrustation.
Main Methods:
- A multi-center, non-concurrent cohort study of 842 patients with DJ ureteric stents.
- Group I (359 patients) received daily ascorbic acid supplements; Group II (483 patients) did not.
- Stent encrustations were assessed using the KUB grading system.
Main Results:
- A significantly lower prevalence of stent encrustations was observed in the ascorbic acid group (2.5% vs. 33.7%, p<0.001).
- Urinary tract infections were less frequent in patients taking ascorbic acid (30% vs. 57.8%, p=0.02).
- Lack of ascorbic acid, male gender, and prolonged stent indwelling time were significant predictors of encrustation.
Conclusions:
- Ascorbic acid supplementation is effective in reducing encrustation on double J ureteric stents.
- Identifying and mitigating risk factors like male gender and prolonged indwelling time is crucial for preventing stent encrustation.

Management of renal calculi focuses on effective strategies like tailored nutrition and hydration therapy. Adjusting diet and fluid intake reduces stone formation and recurrence, making these interventions simple yet powerful in kidney stone prevention and management.Understanding Kidney StonesKidney stones form when calcium, oxalate, uric acid, and cystine concentrate and crystallize in urine. Factors contributing to their formation include genetic predisposition, certain medical conditions,...

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...

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...

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...

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...
