Summary
Pelvic kidneys, a rare congenital anomaly, can develop ureteropelvic junction obstruction. This case highlights the complex management of a massive obstruction in a pelvic kidney.
Area of Science:
- Urology
- Developmental Biology
- Medical Case Reports
Background:
- Pelvic kidney is a congenital anomaly resulting from failed renal ascent during development, affecting 1 in 2200-3000 individuals.
- This condition is often asymptomatic and the kidney typically functions normally.
- Pelvic ureteral junction obstruction (PUJO) can be congenital or acquired, leading to hydronephrosis.
Observation:
- A patient presented with a massive pelvic ureteral junction obstruction.
- The obstruction was located in a pelvic kidney, a rare anatomical variation.
- This led to significant hydronephrosis.
Findings:
- The case involved a complex pelvic ureteral junction obstruction.
- Management strategies for this rare presentation were explored.
- Successful intervention for the massive obstruction was achieved.
Implications:
- This case expands understanding of pelvic kidney complications.
- It underscores the importance of recognizing and managing PUJO in pelvic kidneys.
- Findings may inform future treatment approaches for similar complex urological conditions.

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...

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.

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...

213
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...

360
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...
