Imaging Studies VI: Voiding Cystourethrography and Cystography

42
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...

Urinary Tract Calculi VI: Surgical Management

11
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 Tract Calculi III: Medical Management

10
The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Area of Science:

  • Uro-oncology
  • Pathology

Background:

  • Non-urothelial bladder cancers are uncommon.
  • Colloid carcinoma is a rare subtype of bladder cancer.

Observation:

  • A 72-year-old presented with three months of terminal hematuria.
  • Computed Tomography revealed an anterior bladder wall tumor.

Findings:

  • Transurethral resection and histological examination confirmed bladder colloid carcinoma.
  • Staging revealed pulmonary and bone metastases.

Implications:

  • This case underscores the diagnostic challenge of rare bladder cancers.
  • Metastatic bladder colloid carcinoma requires systemic chemotherapy.
