Summary
Horseshoe kidney (HK) with urological anomalies (UA) requires long-term monitoring. Over half of these cases need surgical intervention, and hydronephrosis can develop obstructively over time.
Area of Science:
- Pediatric Urology
- Congenital Anomalies
- Renal Fusion
Context:
- Horseshoe kidney is the most common renal fusion anomaly.
- Urological anomalies are present in 52% of horseshoe kidney cases.
- Long-term follow-up for asymptomatic horseshoe kidney with urological anomalies is debated.
Purpose:
- To determine the necessity of long-term follow-up for asymptomatic horseshoe kidney (HK) with associated urological anomalies (UA).
Summary:
- A retrospective review of 39 pediatric horseshoe kidney cases diagnosed between 1990-2007 was conducted.
- 46.1% of patients had associated urological anomalies, including hydronephrosis, vesicoureteral reflux, and kidney duplication.
- 55% of these cases required surgical treatment, while others were managed conservatively. Importantly, 50% of obstructions developed over time, necessitating extended monitoring.
Impact:
- Findings suggest that all horseshoe kidney cases with urological anomalies warrant monitoring due to the high rate of surgical intervention.
- The potential for delayed obstructive complications highlights the need for prolonged follow-up in affected children.

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)...
01:26Kidney 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...
01:25Urinary Tract Calculi VI: Surgical Management
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...
01:20Disorders of the Urinary System
The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

01:28Chronic Kidney Disease III: Interprofessional Care
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
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.
