Accuracy and Repeatability of Bladder Volume Measurement Using Ultrasonic Imaging

Objective: This study analyzed the total symptom score, irritative and obstructive domains of IPSS questions regarding quality of life and the urodynamic diagnosis in 400 men with LUTS.Materials and Methods: Four hundred consecutive male patients were prospectively enrolled after being submitted to full urodynamic evaluation and IPSS. Obstructed and non-obstructed patients were compared regarding the symptoms score and quality of life. Results were assessed through Wilcox, ANOVA and Student-t tests.Results: 80.2% were diagnosed as urodynamically obstructed of which 42.4% presented detrusor instability in the filling phase. In obstructed patients there were no statistical difference concerning obstructive or irritative questions from IPSS (p = 0.50). It was not possible either to predict which patients presented detrusor instability based on the questionnaire (p = 0.65). Out of seventy-nine cases unobstructed (19.8%), 65.4% revealed detrusor instability. These cases could not be distinguished from all obstructed men based on the clinical questions measured by IPSS (p = 0.87). Obstructive and irritative questions did not present different indexes than obstructed cases (p = 0.63). Subjective quality of life index did not discriminate obstruction nor it could predict detrusor instability in both groups.Conclusion: Clinical symptoms and quality of life index measured by the IPSS as well as its obstructive and irritative domains do not have discriminating power to predict the presence of infravesical obstruction in males with LUTS, demanding objective tools to demonstrate obstruction.

“…14 On the other hand, urethral catheterization has been accepted as the standard for PVR measurement. 5,6 Although some studies suggest poor correlation between the bladder volumes predicted by ultrasonography and those obtained by urethral catheterization, ultrasonography is a reliable, noninvasive, inexpensive, and simple method that has been used extensively for this purpose. [6][7][8][9][10] In clinical practice, patients whose PVR will be measured are advised to drink a considerable amount of fluid before the examination and to urinate when they experience a moderate to severe desire to void.…”

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.

OBJECTIVE: Acute kidney injury is an important problem in neonates. We conducted a cross-sectional prospective study to determine normal serum blood urea nitrogen, creatinine reference ranges and ranges of ultrasonographic measurement of kidneys in healthy term newborns. STUDY DESIGN:Blood samples were collected from total 357 healthy newborns at birth (n=45), 1 st (n=30), 3 rd (n=61), 7 th (n=34), 10 th (n=132), 14 th (n=36), and 28 th (n=19) days of life. Renal ultrasonographic was performed by the same two radiologists on 81 newborns aged 10 days. RESULTS:Serum blood urea nitrogen and creatinine concentrations have reached to the highest level at the first day of life and have returned to cord level at the third day of life. There were gradually decrease in serum blood urea nitrogen and creatinine levels after the first day of life. There were significant difference in both right and left renal length, width, and volumes in terms of gender and these parameters were statistically higher in boys than girls (p<0.05). Birth weight of the boys (3548±539g) was statistically higher than girls (3307±405 g) (p=0.028). There was a positive correlation between birth weight and right (r=0.38, p=0.000) and left kidney volumes (r=0.44, p=0.000). CONCLUSION:Our findings showed that measured blood urea nitrogen and creatinine levels changed in accordance with postnatal days and there was a positive correlation between kidney volume and birth weight of newborns. We concluded that these findings are important for evaluation of acute kidney injury and for screening of for urinary tract anomalies in neonates.
