Ureters01:22

Ureters

1.2K
The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

Urinary Tract Calculi III: Medical Management

122
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)...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

139
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...

Urinary Tract Calculi VI: Surgical Management

193
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...

Urodynamic Studies: Uroflowmetry

1.9K
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 II: Ultrasonography

183
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...

Area of Science:

  • Urology
  • Health Informatics
  • Medical Device Tracking

Background:

  • A significant percentage of ureteral stent placements result in delayed removals, leading to patient morbidity.
  • Effective tracking systems are needed to ensure timely ureteral stent removal and reduce complications.

Purpose of the Study:

  • To develop and validate a cloud-based software for automated tracking of ureteral stents.
  • To ensure seamless integration with electronic health records (EHR) for efficient patient follow-up.

Main Methods:

  • A cloud-based, EHR-integrated software was developed to automatically register and track patients undergoing ureteral stent placement.
  • A retrospective review of medical records from February 1, 2018, to February 28, 2018, was conducted to validate the software's performance.

Main Results:

  • The software captured all 51 ureteral stents placed during the 1-month pilot study.
  • It identified 18 procedures lacking scheduled follow-up and tracked 10 instances of missed appointments.
  • The system successfully distinguished between procedures with and without pre-scheduled follow-up.

Conclusions:

  • The developed software provides a high-fidelity solution for automated ureteral stent tracking.
  • The system is device-agnostic and integrates seamlessly into EHRs, minimizing workflow disruption.
  • This tool can significantly improve patient care by ensuring timely stent removal.
