Insights

Large congenital bladder diverticula (LCBD) are rare. Transvesical diverticulectomy is a safe and effective surgical treatment for LCBD in children, with good long-term outcomes and no observed complications.

Area of Science:

  • Pediatric Urology
  • Surgical Outcomes
  • Congenital Anomalies

Background:

  • Large congenital bladder diverticula (LCBD) are rare anomalies.
  • LCBD are defined as congenital bladder diverticula greater than 2 cm in diameter.
  • Understanding long-term outcomes is crucial for effective management.

Purpose of the Study:

  • To report long-term surgical and clinical outcomes of children diagnosed with LCBD.
  • To evaluate the efficacy and safety of surgical interventions for LCBD.
  • To analyze patient demographics, symptoms, and surgical approaches.

Main Methods:

  • Retrospective review of medical charts for children diagnosed with LCBD between April 2005 and December 2017.
  • Inclusion criteria: diagnosis of LCBD and at least a 2-year follow-up period.
  • Data collected included demographics, symptoms, operative technique, diverticulum characteristics, and outcomes.

Main Results:

  • Fourteen male patients with 18 LCBD (mean age 53.5 months) were included.
  • Urinary tract infection was the primary complaint in 10 patients; 8 had vesicoureteral reflux.
  • Transvesical diverticulectomy with ureteroneocystostomy (in 12 patients) showed no postoperative infections or recurrent reflux over a median 4.5-year follow-up.

Conclusions:

  • Surgical treatment is the primary approach for LCBD.
  • The transvesical approach for diverticulectomy is a safe and effective long-term surgical procedure for pediatric LCBD.
  • Positive clinical outcomes and low complication rates support this surgical method.

Urinary Bladder01:23

Urinary Bladder

The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

The Micturition Reflex01:26

The Micturition Reflex

Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

Anatomy of the Genitourinary System II: Bladder and Urethra

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

Disorders of the Urinary System01:20

Disorders of the Urinary System

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of 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...

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
