Retrograde nephrostomy and percutaneous calculus removal in 30 patients
The Journal of Urology
|March 1, 1985
Summary
Retrograde nephrostomy offers a reliable method for intrarenal access during percutaneous calculus removal. This technique shows promise as an alternative for stone removal procedures.
Area of Science:
- Urology
- Minimally Invasive Surgery
Background:
- Percutaneous calculus removal is a common procedure for kidney stones.
- Access to the intrarenal collecting system is crucial for successful stone removal.
Purpose of the Study:
- To evaluate the efficacy and safety of retrograde nephrostomy for intrarenal access.
- To assess retrograde nephrostomy as an alternative technique for percutaneous calculus removal.
Main Methods:
- A novel retrograde nephrostomy technique was employed in 30 patients.
- Cystoscopic manipulation of coaxial catheters and a needle for nephrostomy creation under fluoroscopic guidance.
- Procedures were performed under general anesthesia or intravenous sedation with local anesthesia.
Main Results:
- Successful retrograde nephrostomy was achieved in 90% of patients.
- Successful percutaneous calculus removal was achieved in 83% of patients.
- Initial complications and failures were attributed to equipment and learning curve, with overall reliability demonstrated.
Conclusions:
- Retrograde nephrostomy provides reliable and precise intrarenal access.
- This technique can serve as a valuable alternative for percutaneous calculus removal procedures.

01:28Urinary 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...

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)...
01:27Urinary 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,...

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...

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...

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.
