Summary
This case study details bilateral ureteral polyps in an 8-year-old boy, causing intermittent hydronephrosis and hematuria. Surgical intervention for fibroepithelial polyps was successful, with no recurrence observed.
Area of Science:
- Urology
- Pediatric Nephrology
Background:
- Bilateral ureteral polyps are rare, often presenting with obstructive uropathy.
- Intermittent hydronephrosis and gross hematuria are key clinical signs.
Observation:
- An 8-year-old male presented with recurrent flank pain and gross hematuria.
- Imaging revealed bilateral upper ureteral polyps causing intermittent hydronephrosis.
Findings:
- Pathological diagnosis confirmed fibroepithelial polyps.
- Successful surgical management included ureteral resection and anastomosis.
- No recurrence was noted six years post-surgery.
Implications:
- Highlights the importance of considering ureteral polyps in pediatric patients with obstructive uropathy.
- Demonstrates effective surgical strategies for managing bilateral ureteral polyps.
- Emphasizes long-term follow-up for potential recurrence.

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...

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...
01:28Acute Pyelonephritis II: Diagnostic Studies and Management
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...
01:10Nephrons
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma happens...
01:27Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...

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...
