The Streamtest cup offers a simple, inexpensive, and accurate way to assess male urinary stream character. This noninvasive device provides clinically similar results to formal uroflowmetry, aiding in diagnosing urinary obstructive disease.

Area of Science:

  • Urology
  • Medical Devices
  • Diagnostic Tools

Background:

  • Benign prostatic hyperplasia (BPH) frequently causes urinary obstructive disease.
  • Accurate assessment of urinary stream is crucial for diagnosing and managing BPH.
  • Traditional uroflowmetry studies can be costly and require specialized equipment.

Purpose of the Study:

  • To develop an affordable, user-friendly, and accurate noninvasive device for evaluating male urinary stream character.
  • To validate the efficacy of the Streamtest cup against formal uroflowmetry.

Main Methods:

  • A cohort of 50 symptomatic men underwent both a formal in-office uroflow study and used the Streamtest cup.
  • Results from the two methods were compared to assess diagnostic accuracy.

Main Results:

  • Men with urine flow ≥ 12 mL/s consistently reached the red line on the Streamtest cup.
  • Men with urine flow < 11 mL/s were unable to reach the red line.
  • The Streamtest cup demonstrated high concordance with formal uroflowmetry in differentiating normal flow from obstructive uropathy.

Conclusions:

  • The Streamtest cup provides a clinically accurate visual assessment of urinary flow.
  • This device offers a significant cost saving compared to traditional uroflowmetry.
  • The Streamtest cup is a valuable tool for patients and physicians in diagnosing, managing, and monitoring urinary obstructive disease.
