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

Anatomy of the Genitourinary System II: Bladder and Urethra

3.0K
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...

Imaging Studies VI: Voiding Cystourethrography and Cystography

4.0K
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...

Urologic Endoscopic Procedure: Cystoscopic Examination

5.8K
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...

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

4.5K
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...

Nursing Assessment of the Genitourinary System II: Inspection and Palpation

The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease. Look for...

Area of Science:

  • Urology
  • Reconstructive Surgery
  • Pelvic Trauma Management

Background:

  • Incompetent bladder neck (BN) significantly complicates posterior urethroplasty, impacting urinary continence.
  • Pelvic fracture-related BN injuries, often from direct bone trauma, are distinct from shearing urethral injuries.

Purpose of the Study:

  • To outline the diagnosis and management of incompetent bladder neck (BN) during posterior urethroplasty.
  • To review treatment options for restoring urinary continence in cases of BN incompetence.

Main Methods:

  • Diagnosis involves cystography showing an open rectangular BN and suprapubic cystoscopy revealing a fixedly open BN.
  • Treatment strategies include BN reconstruction, artificial sphincters, collagen injections, or bladder flap tubularization.

Main Results:

  • The incidence of BN incompetence during posterior urethroplasty is approximately 4.5%.
  • Risk factors include pediatric patients, bilateral pubic rami fractures, and initial primary realignment.
  • The Young-Dees-Leadbetter procedure for BN reconstruction demonstrates the most successful results.

Conclusions:

  • Managing incompetent bladder neck (BN) requires addressing both urethral continuity and urinary continence.
  • Reconstruction of the bladder neck (BN) is crucial for successful functional outcomes in these complex cases.
