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...

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...

Urologic Endoscopic Procedure: Cystoscopic Examination

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...

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...

Area of Science:

  • Urology
  • Oncology
  • Radiotherapy

Background:

  • A 76-year-old male presented with benign prostatic hyperplasia symptoms.
  • Elevated prostate-specific antigen prompted a biopsy revealing adenocarcinoma (Gleason score 3+4=7).
  • The patient was diagnosed with stage cT1cN0M0 prostate cancer.

Observation:

  • Brachytherapy for prostate cancer was performed in January 2006 without immediate complications.
  • Four months post-procedure, the patient experienced kidney function deterioration.
  • A severely contracted bladder with capacity <5 mL was identified as the cause.

Findings:

  • The patient developed a severely contracted bladder, a rare complication of prostate brachytherapy.
  • Kidney function was significantly impaired due to the bladder's reduced capacity.
  • Diagnostic tests for infection (tuberculosis) and malignancy (cytology) were negative.

Implications:

  • This case highlights a potential, albeit rare, long-term complication of prostate brachytherapy.
  • Severe bladder contracture necessitates careful patient monitoring post-treatment.
  • Further research may explore preventative strategies or management options for this adverse event.
