Insights

This report details the twelfth case of bilateral ectopic ureteroceles in Japan, successfully treated in an infant with urinary tract infections. Surgical intervention preserved kidney function, allowing the patient to void smoothly post-operation.

Area of Science:

  • Pediatric Urology
  • Congenital Abnormalities
  • Surgical Management

Background:

  • Ectopic ureteroceles are rare congenital anomalies, often presenting with urinary tract infections or obstruction.
  • Bilateral involvement is exceptionally uncommon, posing unique diagnostic and therapeutic challenges.
  • Early diagnosis and appropriate surgical intervention are crucial for preserving renal function in affected infants.

Observation:

  • A two-month-old female infant presented with recurrent urinary tract infections.
  • Imaging revealed bilateral ectopic ureteroceles associated with duplex kidneys.
  • Histological examination showed renal dysplasia and immaturity in the upper moieties.

Findings:

  • The patient underwent left heminephrectomy and right pyeloureterostomy with temporary nephrostomy.
  • Postoperative follow-up demonstrated satisfactory ureterocele collapse and smooth voiding.
  • The patient remained asymptomatic for over thirty months, indicating successful management.

Implications:

  • This case highlights successful surgical strategies for managing bilateral ectopic ureteroceles in infants.
  • It underscores the importance of considering renal preservation techniques in complex pediatric urological cases.
  • The findings contribute to the understanding of indications for ureterocelectomy versus upper segment preservation in neonates.

Ureters01:22

Ureters

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...

Acute 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...

Urinary 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...

Kidney 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...

Imaging 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.

Urologic 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...
