Urodynamics is a subdiscipline of urology, an emerging and multifaceted discipline that is based on the basic principles and methods of fluid mechanics and electrophysiology to detect pressure, flow rate and bioelectrical activity in various parts of the urinary tract in order to understand the function and mechanism of urinary tract drainage and the pathophysiological changes of voiding dysfunctional diseases.
A comprehensive urodynamic examination is a more ideal method to visually quantify the function of the urinary tract. In the past two decades, with the rapid development of urodynamics, people have gained a clearer understanding of the mechanisms of lower urinary tract dysfunction, which has had a significant impact on treatment methods and outcomes. Now it has been widely popularized and applied, and has been extended to obstetrics and gynecology, orthopedics, neurological surgery, traumatology and other related disciplines, and has driven the development and improvement of these disciplines.
Our hospital has newly introduced the most advanced urodynamic testing analyzer in China-Netherlands MMS urodynamic testing analyzer, which has a fully digital intelligent system and real wireless Bluetooth measurement technology, mainly used for the examination and diagnosis of bladder and urethral dysfunctional diseases, providing objective basis for the selection of clinical treatment methods and efficacy assessment.
Urodynamic testing can understand the bladder compliance, sensation, volume and contractile function of the forcepsis muscle during the storage and voiding periods. It has greatly improved the diagnosis and treatment of vesicourethral dysfunctional diseases in our department.
The following conditions are suitable for urodynamic examination.
① Difficulty in urination, dribbling, waiting for urine, nocturia;
(2) Frequent urination that affects daily life;
(3) Frequent urinary urgency or even leakage of urine;
④Leakage of urine during exercise, coughing or lifting heavy objects;
(⑤) Worse urination after spinal cord or pelvic surgery;
(6) Urinary incontinence combined with memory loss and difficulty moving;
(7) Inability to urinate or control urination after cerebral hemorrhage, cerebral infarction or traumatic brain injury;
(8) Patients with spinal cord injury, including trauma, tumor and congenital malformation;
⑨ Children with urinary disorders, etc.
Urodynamic examination includes items such as: uroflow rate measurement, bladder pressure volume measurement, urethral manometry, leak point pressure measurement, electromyography, etc.
Precautions before examination.
① Ensure bowel movement before the test;
② Do not urinate 2 hours before the test, the test subject is in the state of desire to urinate;
③The estimated urine volume of the test subject is between 250 ml and 500 ml.
Things to note after the test.
①After the test, there will be a transient pain or slight hematuria after urination.
②After the test, please drink plenty of water to avoid infection.
