|January 29, 2021
Summary
This study reports a rare case of a jackstone in the renal pelvis, successfully treated with minimally invasive surgery. Recognizing jackstones on imaging is key for diagnosing these unusual urinary tract stones.
Area of Science:
- Urology
- Nephrology
- Radiology
Background:
- Jackstones are rare urinary tract calculi, typically found in the bladder.
- Their presence in the renal pelvis is highly unusual due to anatomical constraints.
Observation:
- A solitary, typical jackstone was identified in the renal pelvis.
- The stone caused no significant urinary outflow obstruction.
Findings:
- The renal pelvis jackstone was successfully treated using retrograde intrarenal surgery (RIRS) combined with extracorporeal shockwave lithotripsy (ESWL).
- This case highlights the complex and not fully understood pathophysiology of urinary stone formation.
Implications:
- Accurate radiological identification of jackstone morphology is crucial for diagnosis.
- Further research into the pathophysiological mechanisms of jackstone formation is warranted.

The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.

01:28Urinary Tract Calculi I: Introduction
225
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)...

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...

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

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,...
