Summary
A rare case of left ureteral triplication (Smith type 2) with contralateral duplication and ureterocele in a 10-year-old boy highlights the importance of early diagnosis for preventing kidney damage.
Area of Science:
- Pediatric Urology
- Congenital Anomalies
- Radiology
Background:
- Ureteral anomalies are uncommon congenital abnormalities affecting the urinary tract.
- Nocturnal enuresis can be a symptom of underlying urological conditions.
- Ureteral triplication, particularly Smith type 2, is exceptionally rare.
Observation:
- A 10-year-old male presented with persistent nocturnal enuresis.
- Radiological imaging identified a left ureteral triplication (Smith type 2).
- Contralateral ureteral duplication and a ureterocele were also noted.
Findings:
- The patient exhibited an extremely rare combination of ureteral anomalies.
- The specific presentation involved a triplicated left ureter and a duplicated right ureter with a ureterocele.
- This complex anomaly was diagnosed via radiological workup.
Implications:
- Early diagnosis of such rare congenital anomalies is crucial.
- Prompt management can prevent serious complications like recurrent urinary tract infections and renal damage.
- This case underscores the need for thorough investigation in pediatric patients with persistent enuresis.

01:22Ureters
The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...
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...
01:25Urinary 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...
01:28Urinary 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...
01:22Imaging Studies V: Intravenous Urography and Retrograde Pyelography
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.

The upper urinary system comprises two kidneys and two ureters, which are crucial in filtering blood and forming urine.KidneysLocation and Structure:The kidneys are two bean-shaped organs positioned behind the peritoneum on either side of the spine.Kidneys are between the 12th thoracic (T12) and the 3rd lumbar (L3) vertebrae.The position of the liver causes the right kidney to sit slightly lower than the left.Protective Layers:Each kidney is enveloped in a tough, fibrous membrane called the...
