Summary
Ureteral stents are not always necessary after simple procedures, but can reduce complications in high-risk patients. New stent designs aim to minimize discomfort and encrustation.
Area of Science:
- Urology
- Biomaterials Science
Background:
- Ureteral stents are commonly used in urological interventions.
- Stent-related complications, including pain, infection, and encrustation, are significant concerns.
Purpose of the Study:
- To review recent literature on ureteral stent materials, designs, indications, and complications.
- To provide an update on managing stent-related issues.
Main Methods:
- Systematic review of English-language articles published between 2000 and 2006.
- Focused on new and updated review articles concerning ureteral stents.
Main Results:
- Routine stenting does not improve stone-free rates after uncomplicated ureteroscopy or shock wave lithotripsy.
- Patients undergoing certain procedures or with specific conditions (e.g., pregnancy, UTIs) are at higher risk for complications.
- New stent materials and designs show promise in reducing morbidity like pain and encrustation.
Conclusions:
- Stenting is not mandatory for all patients post-ureteroscopy or shock wave lithotripsy.
- A subset of patients benefits from stenting due to elevated complication risks.
- Further development of biomaterials, including drug-eluting stents, is needed to prevent infection and encrustation.

Urinary Tract Calculi III: Medical Management
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)...
Urinary Tract Calculi VI: Surgical Management
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...
Urinary Tract Calculi V: Nursing Management
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...
Urinary Tract Calculi IV: Nutrition Therapy and Prevention
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,...
Urinary Tract Calculi I: Introduction
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...
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...
