Anatomy of the Genitourinary System II: Bladder and Urethra01:19

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...

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...
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...

Summary
This summary is machine-generated.

Bladder neck transection surgery effectively treats intractable urinary incontinence in children, achieving a 98% continence rate after revisions. This procedure is a viable option for complex cases with damaged bladders.

Area of Science:

  • Pediatric Urology
  • Reconstructive Surgery

Background:

  • Intractable urinary incontinence in children often requires complex surgical solutions.
  • Previous reconstructive attempts may fail, necessitating advanced interventions.

Purpose of the Study:

  • To evaluate the indications, technique, and outcomes of bladder neck transection in pediatric patients.
  • To assess the efficacy and safety of this procedure for intractable urinary incontinence.

Main Methods:

  • Retrospective review of 76 pediatric patients (1996-2006) undergoing bladder neck closure.
  • All patients had concomitant augmentation cystoplasty and a catheterizable stoma.
  • Analysis of demographics, operative details, complications, and long-term outcomes.

Main Results:

  • Initial continence achieved in 86% of patients with over 12 months follow-up (n=50).
  • Final continence rate reached 98% after revisions for primary failures.
  • Complications included stones (30%) and new hydronephrosis (8 renal units); no spontaneous bladder ruptures.

Conclusions:

  • Bladder neck transection with augmentation and a continent stoma is effective for severe bladder outlet damage and incontinence.
  • This approach is suitable when other reconstructive methods have failed or are unlikely to succeed.
  • Risks of poor renal outcomes and bladder perforation appear minimal with this technique.
