Summary
A rare case of crossed renal ectopia complicated by ureteropelvic junction obstruction in a 49-year-old woman led to nephrectomy. This highlights the importance of considering complex congenital anomalies in abdominal mass investigations.
Area of Science:
- Urology
- Nephrology
- Congenital Abnormalities
Background:
- Crossed renal ectopia is a rare congenital anomaly where one or both kidneys are located on the contralateral side of the abdomen.
- Ureteropelvic junction obstruction (UPJO) is a blockage at the point where the renal pelvis meets the ureter, impeding urine flow.
Observation:
- A 49-year-old woman presented with an abdominal mass.
- Radiological imaging revealed a non-functioning right kidney in a crossed ectopia.
- Surgical exploration confirmed crossed fused renal ectopia with severe ureteropelvic junction obstruction.
Findings:
- The patient's crossed fused kidney was non-functional due to ureteropelvic junction obstruction.
- Nephrectomy (surgical removal of the kidney) was performed.
- The patient experienced a good outcome following the nephrectomy.
Implications:
- This case underscores the diagnostic challenges posed by rare congenital renal anomalies.
- It emphasizes the need for thorough radiological assessment in cases of unexplained abdominal masses.
- Management of complicated crossed renal ectopia requires individualized surgical planning.

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...
01:22Imaging 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.

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...
01:28Urologic Endoscopic Procedure: Cystoscopic Examination
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
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...
01:26Urinary 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...
