Summary
Cystic renal tumors in children encompass cystic nephroma (CN), cystic partially differentiated nephroblastoma (CPDN), and Wilms' tumor (WT) with cystic areas. Accurate diagnosis is crucial for appropriate treatment, with CN and CPDN treated surgically, while WT requires multimodal therapy.
Area of Science:
- Pediatric Pathology
- Pediatric Oncology
- Renal Tumors
Context:
- Cystic renal tumors are rare in children.
- Distinguishing between benign and malignant cystic renal lesions is critical for treatment planning.
Purpose:
- To present the clinico-pathological features of cystic renal tumors in childhood.
- To discuss diagnostic and classification criteria for these tumors.
Summary:
- Five cystic renal tumors were identified: 3 cystic partially differentiated nephroblastomas (CPDN), 1 cystic nephroma (CN), and 1 Wilms' tumor (WT) with cystic areas.
- CN is benign, CPDN is low-risk malignant, and WT with cystic areas is similar to classical WT.
- All patients treated per SIOP protocol showed no evidence of tumor recurrence after at least 6 years.
Impact:
- Accurate diagnosis of cystic renal lesions is mandatory for appropriate treatment.
- This study clarifies the spectrum of cystic renal tumors in children, aiding in their management.
- Establishes the favorable prognosis for CN and CPDN with surgical treatment alone.

01:26Kidney Transplant II: Surgical Procedure
Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
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...
01:30Urinary 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)...
01:26Urinary 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...
01:45Kidney Structure
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.
01:12Internal Anatomy of the Kidney
The kidneys are essential organs in the human body, performing a myriad of tasks that maintain homeostasis and overall health.
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
