Bacillus Calmette-Guérin (BCG) immunotherapy is the most effective treatment for carcinoma in situ and high-risk non-muscle invasive bladder cancer (NMIBC). However, it can also provoke diverse side effects. We found 1 patient with a significantly and rapidly reduced bladder volume after the instillation of BCG. Few such cases and corresponding treatments have been reported. We speculated that the tuberculosis infection existed, so antitubercular therapy was given. After a 3-month oral intake of rifampicin, isoniazid, and ofloxacin, the volume of bladder returned to normal and the voiding symptoms disappeared. This case indicated that the reduction of bladder volume caused by BCG instillation could be treated with antitubercular therapy. Prompt and accurate diagnosis was important for the management.

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...

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...

Urodynamic Studies: Uroflowmetry

Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...
