Summary
This study introduces a new dataset of annotated urinary cells to aid in diagnosing urinary tract infections (UTIs). This resource enables machine learning for faster, more accessible UTI diagnosis using simple imaging systems.
Area of Science:
- Medical Imaging
- Computer Vision
- Machine Learning
Background:
- Urinary tract infection (UTI) diagnosis relies on manual urine microscopy, which is labor-intensive and error-prone.
- A lack of clinical image datasets has hindered the adoption of computer vision for UTI diagnosis.
Purpose of the Study:
- To present an open-access dataset of annotated urinary cells from UTI patients.
- To demonstrate the utility of this dataset in training a deep learning model for automated cell recognition.
Main Methods:
- An open dataset of 300 images with 3,562 manually annotated urinary cells (seven classes) was created from unstained urine of symptomatic UTI patients.
- A novel deep learning architecture, Patch U-Net with a random patch generator, was trained using this dataset.
Main Results:
- The Patch U-Net model was successfully trained to recognize urinary cells.
- The dataset facilitates the development of automated UTI diagnostic tools.
Conclusions:
- This annotated dataset is a valuable resource for advancing computer-aided UTI diagnosis.
- The developed deep learning approach shows promise for near-universal UTI diagnosis in clinical settings using simple imaging.

01:26Urinary Tract Infection I: Introduction
Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...
01:25Urinary Tract Infection II: Pathophysiology
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
01:30Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
01:26Urine Studies II: Urine Culture and Sensitivity Test
A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...
01:28Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
01:24Automated Microbial Diagnostics
Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...
