Insights

Most children with retained ureteral stumps after upper pole heminectomy for duplex kidneys do not need further surgery. Long-term outcomes show residual ureteral stumps are generally safe.

Area of Science:

  • Pediatric Urology
  • Nephrology
  • Surgical Outcomes

Background:

  • Duplex kidneys are a common congenital anomaly.
  • Upper pole heminephrectomy is performed for nonfunctioning moieties.
  • Retained ureteral stumps are a potential complication.

Purpose of the Study:

  • To evaluate the long-term outcomes of retained ureteral stumps in children.
  • To determine the necessity of stump resection after upper pole heminephrectomy.

Main Methods:

  • Retrospective review of 50 pediatric patients undergoing upper pole heminephrectomy.
  • Data collected from January 1990 to December 2000.
  • Analysis of indications, follow-up duration, and complications.

Main Results:

  • Indications included ureterocele (50%), ectopic ureter (30%), and others.
  • 96% of ureters were managed by transfixation.
  • Stump excision was needed in 10% for recurrent urinary tract infections due to vesicoureteral reflux.

Conclusions:

  • Long-term follow-up indicates that most residual ureteral stumps are asymptomatic.
  • Further resection of ureteral stumps is not typically required.
  • Conservative management is often sufficient for retained ureteral stumps.

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...

Kidney 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.

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...
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...
