Summary
The BladderScan BVI 6200 device is not accurate enough for measuring bladder volumes in children. It cannot reliably replace conventional ultrasound in bladder retraining programs.
Area of Science:
- Pediatric Urology
- Medical Device Technology
- Diagnostic Imaging
Background:
- Bladder scans are crucial for estimating urinary volumes in adult urology.
- Smaller bladder scan devices exist for pediatric use, but literature on their accuracy is conflicting.
- The BladderScan BVI 6200 was developed to improve accuracy in pediatric bladder volume measurement.
Purpose of the Study:
- To evaluate the accuracy of the BladderScan BVI 6200 in measuring pediatric bladder volumes.
- To determine if the BVI 6200 can replace conventional ultrasound in bladder retraining programs for children.
Main Methods:
- 84 children (mean age 7.8 years) participated in the study.
- Bladder volumes were measured using the BVI 6200, conventional ultrasound, and a graduated cylinder.
- Data were analyzed using Bland-Altman analysis to compare measurements.
Main Results:
- While mean volume differences were within 10%, the spread of measurements was very large.
- Significant over- and under-estimations were observed across different measured volumes.
- The device demonstrated considerable variability in accuracy.
Conclusions:
- The BladderScan BVI 6200 is not sufficiently reliable for accurate bladder volume measurement in children.
- The device is not recommended as a replacement for conventional ultrasound in pediatric bladder retraining programs.

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
01:22Imaging 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...
01:23Urinary 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...

01:19Anatomy 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...
01:28Imaging Studies I: Kidney, Ureter, and Bladder Studies
Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...
01:19Urodynamic 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...
