Urodynamic Studies: Uroflowmetry01:19

Urodynamic Studies: Uroflowmetry

766
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...

Imaging Studies VI: Voiding Cystourethrography and Cystography

171
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...

Imaging Studies II: Ultrasonography

69
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...

Urine Studies I: Urinalysis

235
Urinalysis is a widely used diagnostic test that analyzes urine's physical, chemical, and microscopic characteristics. Healthcare providers use it to detect and monitor various health conditions, including renal disease, urinary tract infections (UTIs), diabetes, and metabolic or systemic disorders.Components of UrinalysisUrinalysis consists of three primary components: physical, chemical, and microscopic examination. Each provides unique insights into the urine sample and, by extension, the...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

215
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1. Intravenous Urography (IVU)Intravenous...

Urinary Bladder01:23

Urinary Bladder

1.6K
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...

Area of Science:

  • Urology
  • Medical Technology
  • Digital Health

Background:

  • Conventional paper-based voiding diaries (VD) are standard for monitoring urinary symptoms.
  • Limitations of paper VD include potential compliance issues and subjective data recording.
  • Novel digital solutions are being explored to improve patient data collection accuracy and convenience.

Purpose of the Study:

  • To evaluate the utility of a novel acoustic uroflowmetry (UFM)-based mobile application (app) voiding diary (VD).
  • To assess patient compliance and satisfaction with the mobile app VD compared to paper-based VD.
  • To determine the correlation between data collected by the mobile app VD and a conventional paper-based VD.

Main Methods:

  • A total of 78 patients participated in the study between December 2019 and June 2020.
  • Data collected included a survey on convenience, satisfaction, and preference between the two VD methods.
  • Compliance and correlation of key voiding parameters (e.g., 24-hour urine volume, nocturnal polyuria index, maximal bladder capacity) were analyzed.

Main Results:

  • The mobile app VD received significantly higher scores for convenience (7.47 vs. 4.20) and satisfaction (7.36 vs. 5.07) compared to paper VD.
  • Patients expressed a strong preference for the mobile app VD, with a median score of 9 out of 10.
  • Good correlations were observed between the mobile app and paper VD for nocturnal urine volume (r=0.55), total voids (r=0.9), nocturnal voids (r=0.83), and maximal bladder capacity (r=0.89).

Conclusions:

  • The acoustic UFM-based mobile app VD demonstrates superior convenience and patient satisfaction.
  • The mobile app VD shows good correlation with conventional paper-based methods for key urodynamic parameters.
  • This digital UFM-based VD presents a favorable and effective alternative to traditional paper diaries.
