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]
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.
decreased the post-void residual volume; increased the maximum urinary flow, comparable with pharmacological intervention; and; decreased the voiding time. This urodynamic profile is associated with a lower risk of urologic complications, such as cystitis and bladder stones.
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 .
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.
Rather, this residual space is paved for parking lots that detach buildings from the rest of the city fabric. [19] Hence, Rowe called for a transcendence of space fixation and object fixation to create an urban environment where building and space achieve balance and a figure ground with shared dialogue between solid and void.
