“…In most of the studies, ultrasonographic PVR measurement with an automated real-time calculation is found to be as affective as catheterization [7][8][9][10]. However other studies found this modality to be limited and less accurate than catheterization [6,11]. In the studies that are against the use of ultrasonographic PVR measurement, we see that conventional ultrasonograhy was used to measure PVR.…”

Postvoid residual urine (PVR) measurement with a bladder scanning portable ultrasonographic device is an easy and non invasive method. Its use has been wide spread in men and women however its accuracy and reliability in children is still under debate. The aim of this study was to investigate the reliability of PVR measurement with real time bladder scanning in comparison with catheterization in children with voiding disorders. Postvoid residual urine measurements were routinely undertaken in patients to whom urodynamics were done, prospectively. Urinary catheterization was routinely done in all patients for cystometry. After uroflowmetry, residual urine was measured with a portable ultrasound device which readily measured the amount of PVR. After this measurement, bladder was emptied via the cystometry catheter and the drainage was noted. The age, sex and the diagnosis of the patients were also noted. The comparison between two measurements were done with paired sample t test. A total of 114 measurements were done in 89 patients. Mean age was 9±0,4 years (between 5 months to 21 years). There were 54 girls and 35 boys. The indication for urodynamics was nonneurogenic causes in 55 and neurogenic, in 34 patients. Mean PVR with ultrasonographic measurement was 56,6±6,6 ml and 56,7±7,4 ml with catheter. The difference between two measurements was statistically insignificant. Real time ultrasonographıc measurement with a bladder scanning device may be an easy, feasible, and reliable method to detect PVR in children with voiding disorders. This method may be preferred in appropriate indications like residual urine measurement in uroflowmetry+EMG studies where urinary catheterization is not necessary.

“…Although UC is reliable method, it is invasive and cause distress in children. UC has also cause urethral trauma and urinary tract infection (7). Rosseland et all (8) found that the bladder emptying with catheter was in complete in 30 % of patients and cause wrong measurement of PVR.…”

Aim: Postvoiding residual (PVR) urine is measured by urethral catheterization (UC), portable ultrasonography (USG) or voiding cystourethrogram (VCUG) images. We evaluated those three different PVR assessment methods and parameters that may interfere with the results.Patients and Methods: Eighteen patients with spinal bifida (SB) (10 female and 8 male, mean 6.2±0.83 years old) (Group I) Fourteen patients with lower urinary tract symptoms (LUTS) (5 female and 9 male, mean 7.4± 0.6)(Group II). PVR measurements were performed by urethral catheterization (UC), portable Caresono PadScan HD 5 ® USG and on voiding cystourethrogram (VCUG) images. Relation with vesicourethral reflux (VUR), renal scaring (on DMSA), bladder trabeculation (BT) is evaluated.Results: Mean PVR volumes approximately same in the catheter and ultrasound groups (p>0.05). PVR is less in the VCUG grup when compare other groups but statistically not significant (p>0.05). Significant correlation between catheter PVR and USG PVR group (p<0 .01, r: 0.94 and r:0.96) . Although no significant difference is demonstrated for VUR in both groups (p>0.05), PVR values are higher in patients with higher VUR degrees. There was no statistical difference according to existing of scaring in both groups (p>0.05). There was no statistical difference according to existing bladder trabeculation in both groups (p>0.05)Conclusion: Measurement of PVR by portable ultrasonography yields comparable results with urethral catheterization. Although PVR measurement on VCUG images is a less reliable method, it can provide additional information in certain conditions (ie. VUR, diverticulum..). Although statistical significance could not be demonstrated, we believe that VUR, renal scaring and bladder trabeculation may interfere with the results of PVR assessments.

“…[5] PVR can be measured by transabdominal ultrasound, which is a simple, accurate, and noninvasive method. [6] However, a feeling of incomplete emptying does not always strongly correlate with measured PVR volume. [7] Urologists occasionally encounter men with LUTS complaining of a feeling of incomplete emptying despite no or little PVR.…”

Purpose: This study was conducted to assess the clinical value of postvoid residual (PVR) urine measurement and associate it with the feeling of incomplete emptying in men with lower urinary tract symptoms. Methods: Two hundred men were surveyed in the King Fahd Hospital of the University. Patients who had previous urological surgery and patients who are currently on urology treatment were excluded. Information from the remaining 181 patients was analyzed. International Prostate Symptom Score (IPSS) sheets were filed, and then, the PVR was measured. Results: Data from IPSS sheets were evaluated: 45 patients (24.8%) were characterized as experiencing no symptoms (Score: 0 and 1), 87 (48%) as mild-to-moderate symptoms (Score: 2 and 3), and 49 (27%) as severe symptoms (Score: 4 and 5). The PVR measurement showed no statistical difference in all three categories (being 10, 13, and 12, respectively). Feeling of incomplete emptying despite little PVR was frequently observed. Conclusion: The study concluded that the feeling of incomplete emptying was poorly correlated with PVR urine volume measurement. This feeling was significantly associated with worsening of both voiding and storage symptoms.
