The urine volume is measured (this shows how efficiently the bladder empties). High volumes (180 ml) may be associated with urinary tract infections. [5] A volume of greater than 50 ml in children has been described as constituting post-void residual urine. [6] High levels can be associated with overflow incontinence.
A post-void residual urine greater than 50 ml is a significant amount of urine and increases the potential for recurring urinary tract infections. [citation needed] In adults older than 60 years, 50-100 ml of residual urine may remain after each voiding because of the decreased contractility of the detrusor muscle. [7]
A 2014 meta-analysis found that, for elderly males with LUTS, sitting to urinate meant there was a decrease in post-void residual volume (PVR, ml), increased maximum urinary flow (Qmax, ml/s), which is comparable with pharmacological intervention, and decreased the voiding time (VT, s). [19]
MSA is characterized by the following: Autonomic and at least one Motor (clinically established MSA criteria 2022) [6] [7] autonomic dysfunction: Post-void urinary residual volume ≥100 mL (usually by ultrasound); Unexplained urinary urge incontinence; or Neurogenic orthostatic hypotension (≥20/10 mmHg blood pressure drop) within 3 minutes (usually by head‐up tilt)
Measurement of post-void residual by medical ultrasound is an easy procedure that is sufficient in most cases. Patients with this condition presenting additionally with hydronephrosis , stage 3 chronic kidney disease , or recurrent urinary tract infection or urosepsis were considered as high risk groups.
the post void residual volume (PVR, ml) was significantly decreased; the maximum urinary flow (Qmax, ml/s) was increased; the voiding time (VT, s) was decreased; This urodynamic profile is related to a lower risk of urologic complications, such as cystitis and bladder stones.
Post-void dribbling, also known as post-micturition dribbling, occurs when urine remaining in the urethra after voiding the bladder slowly leaks out after urination. A common and usually benign complaint, it may be a symptom of urethral diverticulum , prostatitis and other medical problems.
Residual volume, air remaining in the lungs after a maximal exhalation; see lung volumes Residual volume, urine remaining in the bladder after voiding; see urinary retention Gastric residual volume (GRV) is the volume of food or fluid remaining in the stomach at a point in time during enteral tube nutrition feeding .
