Bladder Post Void Residual Volume - StatPearls - NCBI Bookshelf

Post-void residual volume (PVR) is the amount of urine retained in the bladder after a voluntary void and functions as a diagnostic tool. A PVR can be used to assess many disease processes, including but not limited to neurogenic bladder, cauda equina syndrome, urinary outlet obstruction, mechanical obstruction, medication-induced urinary retention, postoperative urinary retention, and urinary tract infections. The PVR may be determined through urinary catheterization, a portable dedicated ...

Understanding Urine Residual Volumes: What's Normal?

Post-void residual (PVR) urine volume refers to the amount of urine left in the bladder after urination. Typically, a small amount of residual urine is considered normal, with sources stating that a volume of less than 50 mL is adequate bladder emptying, while a volume of more than 100 mL is considered abnormal. However, PVR volumes may vary depending on individual factors, and healthcare providers will consider a patient's specific circumstances when evaluating PVR results. ...

What is an abnormal post-void residual (PVR) volume?

However, most urologists consider volumes of 50 ml to 100 ml to constitute the lower threshold of abnormal PVR (1). Large PVRs are associated with urinary tract infections, especially in persons at risk (e.g. diabetes, spinal cord injury), while very large PVRs (>300 ml) may be associated with an increased risk of upper urinary tract dilatation and renal insufficiency.

Bladder Ultrasound and Measurement of Postvoid Residual Volume

The postvoid residual volume is calculated using the formula: Postvoid residual volume (PVR) = length × width × height × 0.5. Various factors ranging from 0.5–0.7 are found in the literature. Depending on the bladder shape, considerable inaccuracy is possible. Usually, there is no residual urine. PVR volumes over 100–ml are considered significant in adults. In children, a PVR volume exceeding 10% of the urinary bladder capacity is pathological (Riedmiller et al., 2001).
