“…10 Our findings are basically in accordance with those of Alivizatos et al, 10 but those authors have also stated that the measurement of PVR in a patient should be performed at the first desire to void. On the other hand, the least mandatory prevoiding bladder volume for useful uroflowmetry was determined to be 200 mL 16 ; however, in our study, the mean V 1 calculated before the first sensation to void was 117.7 mL. Thus, contrary to Alivizatos et al, 10 we think that PVR values calculated after the first sensation to void will not be enough and may also cause unreliable results.…”

“…Hence, the optimum timing to measure PVR seems to be at the moderate feeling of micturition; however, this feeling may be highly variable as well. In a previous study, Dicuio et al 16 proposed prevoiding bladder ultrasonography for determination of at least a 200-mL bladder volume for a useful uroflowmetry test. We likewise propose the measurement of premicturitional bladder volume by ultrasonography and for performing PVR measurements if Values are mean ± SD the V 1 is greater than 540 mL.…”

Objective. The purpose of this study was to evaluate the effect of premicturitional bladder volume (V 1 ) on postvoid residual urine volume (V 2 ) measurements and to assess the ideal V 1 for an accurate V 2 determination. Methods. Twenty-five healthy men without any urinary symptoms constituted the study group. Measurements by transabdominal ultrasonography for V 1 and V 2 were performed for each subject at 3 different phases, each of which was preceded by oral intake of 1000 mL of water and accompanied by "mild," "moderate," and "severe" sensations of micturition, respectively. Results. Mean ± SD V 1 and V 2 during the first, second, and third phases were 117.7 ± 70.3 and 1 ± 1, 356.2 ± 112.3 and 11.5 ± 12 and 639.6 ± 171.8 and 58.8 ± 35.2 mL, respectively. With 50 mL as the cutoff value for a pathologic V 2 , 15 (60%) men had V 2 in the third phase exceeding this value, whereas the same rate was calculated as 0% for either of the first 2 phases. No patient with V 1 of less than 540 mL had V 2 of greater than 50 mL. Conclusions. Postvoid residual urine volume measurements with an uncomfortably full bladder result in high false-positive postmicturitional residue values even in healthy young men. We strongly advise that V 1 measurements of the bladder be performed before V 2 measurements and that V 2 not be measured if V 1 is greater than 540 mL. Key words: bladder; residual volume; ultrasonography. he accurate determination of postvoid residual urine (PVR) volume (V 2 ) is an important factor for diagnosing voiding dysfunction and for making a decision regarding the treatment options in the management of benign prostatic hyperplasia.

“…Dicuio et al have published the formula: volume in ml ¼ height Â depth Â transverse Â 0:5, to more accurately determine bladder volume using US measurements ( Figure 11). 18,[23][24][25] Urinary retention is present if postvoid bladder volume is greater than 150 ml. 23,24 Alternatives to bladder PoCUS are commercial bladder scanners.…”

“…18,[23][24][25] Urinary retention is present if postvoid bladder volume is greater than 150 ml. 23,24 Alternatives to bladder PoCUS are commercial bladder scanners. However, these machines may not be readily available and more concerning, without direct bladder visualization, may leave operators wondering if they are measuring the correct structure in the pelvis.…”

My patient has abdominal and flank pain: Identifying renal causes

et al. 2015

Acute flank and abdominal pain are common presenting complaints in the emergency department. With increasing access to point-of-care ultrasound (PoCUS), emergency physicians have an added tool to help identify renal problems as a cause of a patient's pain. PoCUS for hydronephrosis has a sensitivity of 72-83.3% and a varying specificity, similar to radiology-performed ultrasonography. In addition to assessment for hydronephrosis, PoCUS can help emergency physicians to exclude other serious causes of flank and abdominal pain such as the presence of an abdominal aortic aneurysm, or free fluid in the intraperitoneal space, which could represent hemorrhage. Use of PoCUS for the assessment of flank pain has resulted in more rapid diagnosis, decreased use of computed tomography, and shorter emergency department length of stay.
