What is significant post void residual urine?
Post void residual urine (PVR) refers to the amount of urine that remains in the bladder after urination. It is an important parameter that healthcare professionals use to assess the functionality of the urinary system. The significance of PVR lies in its ability to indicate various urinary health issues, including bladder outlet obstruction, bladder dysfunction, and neurological disorders. In this article, we will explore the importance of PVR, its measurement methods, and its implications for patient care.
The normal PVR is considered to be less than 100 milliliters (ml) in adults. If the PVR exceeds this value, it is considered significant and may indicate a problem with the urinary system. Several factors can contribute to an increased PVR, including:
1. Bladder outlet obstruction: Conditions such as benign prostatic hyperplasia (BPH) in men and urethral strictures can obstruct the flow of urine, leading to an increased PVR.
2. Bladder dysfunction: Conditions like overactive bladder (OAB) and neurogenic bladder can cause the bladder to not empty completely, resulting in a higher PVR.
3. Neurological disorders: Conditions such as spinal cord injury, multiple sclerosis, and stroke can affect the nerves that control bladder function, leading to an increased PVR.
Measuring PVR is a straightforward procedure that can be performed in various settings, including clinics, hospitals, and even at home with the use of a catheter. The following methods are commonly used to measure PVR:
1. Manual measurement: After urination, a healthcare professional or patient can manually measure the amount of urine left in the bladder using a catheter or a urinal.
2. Voiding cystourethrogram (VCUG): This imaging technique involves injecting a contrast dye into the bladder and taking X-rays to visualize the urinary tract and measure PVR.
3. Ultrasound: An ultrasound can be used to measure the volume of urine remaining in the bladder after urination.
The significance of PVR lies in its ability to provide valuable information about the patient’s urinary health. An increased PVR can lead to complications such as urinary tract infections, kidney damage, and bladder stones. By identifying the underlying cause of an increased PVR, healthcare professionals can develop an appropriate treatment plan to address the issue.
In conclusion, significant post void residual urine is a critical parameter that can indicate various urinary health issues. Healthcare professionals should pay close attention to PVR measurements and consider appropriate diagnostic and treatment options based on the findings. Regular monitoring of PVR can help prevent complications and improve the quality of life for patients with urinary system problems.
