Insights

Ureteral reconstruction after pelvic and abdominal tumor resection or stricture is feasible in pediatric oncology patients. Surgical repair can preserve renal function and improve outcomes, with no tumor recurrence or renal complications observed in this study.

Area of Science:

  • Pediatric Oncology
  • Urology
  • Surgical Reconstruction

Background:

  • Pelvic and abdominal tumors can involve ureteral segments, necessitating resection.
  • Ureteral strictures may arise as a consequence of intensive cancer therapy.
  • Urinary reconstruction is crucial for preserving renal function in affected pediatric patients.

Purpose of the Study:

  • To present the experience with urinary reconstruction in pediatric oncology patients with ureteral involvement due to tumors or strictures.
  • To evaluate the efficacy and outcomes of ureteral reconstructive procedures in this patient cohort.
  • To assess the impact of reconstruction on renal function and oncologic control.

Main Methods:

  • Retrospective review of pediatric oncology patients undergoing ureteral reconstruction for solid abdominal/pelvic tumors.
  • Data collection included diagnosis, surgical procedures, renal function parameters, and follow-up status.
  • Follow-up assessments involved serum urea nitrogen/creatinine levels and renal scans.

Main Results:

  • Thirteen pediatric patients (8 male, 5 female; mean age 10.1 years) were identified.
  • Common indications included en bloc tumor resection (n=8) and ureteral strictures (n=3).
  • Boari flap, Leadbetter-Politano reimplantation, and psoas hitch were frequent procedures; 2 patients had elevated renal function markers, and no renal complications or tumor recurrences were noted.

Conclusions:

  • Ureteral involvement in abdominal and pelvic tumors requires reconstructive surgery for complete tumor resection and improved survival.
  • Ureteral reconstruction effectively preserves renal function in pediatric patients with post-therapy strictures.
  • Surgical management of ureteral compromise in pediatric oncology is associated with favorable oncologic and renal outcomes.

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...
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...

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.

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...

Anatomy of the Genitourinary System I: Kidneys and Ureters

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...
