Aim: We aimed to compare pre-voiding bladder and post-voiding residual (BV, PVR) volumes measured by portable ultrasonic scanner (PUS) in standing and supine positions. Material and Methods: A total of 436 children were included. We composed 2 groups (group-1: PUS vs. volume by catheter, group-2: PUS vs. infused volume during urodynamic study) to evaluate the agreement of PUS measurements with actual bladder volume and then third group (group-3) to analyze the correlation of PUS measurements in standing vs. supine positions. In groups 1 and 2, agreement of measurements were evaluated by paired sample T or Wilcoxon signed rank tests. Following confirmation of agreement, correlations were analyzed by Pearson’s or Spearman’s coefficients in all groups. Interpretation of coefficients were done as 0.90-1.00 (very high correlation) and 0.70-0.90 (high correlation), respectively. Results: In group-1, measurements (catheter vs. PUS) were similar (Wilcoxon Signed rank test, p= 0.976) and were highly correlated (r=0.873). In group-2, measurements of bladder volumes infused by urodynamic device and volumes by PUS were similar that revealed the agreement of PUS measurements on different volumes and highly correlated at the 25th and very highly correlated at the 50th, 75th and 100th percentiles of the EBC (estimated bladder capacity related to age). In group-3, BV and PVR measurements by PUS in standing and supine positions were highly correlated that revelaed PUS can be used in both positions. Conclusion: Measurements of BV before uroflowmetry or PVR volume by PUS in standing position gave similar results with those in supine position.

Accurate determination of intravesical residual urine volume as well as bladder capacity is of significant importance in children. The ability to confirm these measurements non invasively in children avoids discomfort, urethral trauma and the introduction of urinary tract infection. Also, by avoiding the need for catheterization this technique permits more physiological assessment and allows for repeated examinations without fear and anxiety on the part of the patients. In this prospective study we assess the accuracy of the real time, hand held, ultrasonic device using suprapubic views and biplanar technique to determine intravesical volumes. Real time ultrasonography with suprapubic views and the described bi-planar technique to determine intravesical urine volume is simple, accurate and reproducible. It also is rapid and noninvasive, and can detect accurately an empty bladder in children. A strong correlation was found between the estimated bladder volume with our method and voided urine volume (0 ml, residual volume) .This study concluded that the modality used in this study has the potential to provide useful and reproducible information in the clinical evaluation of bladder function in children.DOI: http://dx.doi.org/10.3329/jdnmch.v17i2.12199 J.

Abstract Background Knowledge of risk factors for postoperative urinary retention may guide appropriate and timely urinary catheterization. We aimed to determine independent risk factors for postoperative urinary catheterization in general surgical patients. In addition, we calculated bladder filling rate and assessed the time to spontaneous voiding or catheterization. We used the patients previously determined individual maximum bladder capacity as threshold for urinary catheterization. Methods Risk factors for urinary catheterization were prospectively determined in 936 general surgical patients. Patients were at least 18 years of age and operated under general or spinal anesthesia without the need for an indwelling urinary catheter. Patients measured their maximum bladder capacity preoperatively at home, by voiding in a calibrated bowl after a strong urge that could no longer be ignored. Postoperatively, bladder volumes were assessed hourly with ultrasound. When patients reached their maximum bladder capacity and were unable to void, they were catheterized by the nursing staff. Bladder filling rate and time to catheterization were determined. Results Spinal anesthesia was the main independent modifiable risk factor for urinary catheterization (hyperbaric bupivacaine, relative risk 8.1, articaine RR 3.1). Unmodifiable risk factors were a maximum bladder capacity < 500 mL (RR 6.7), duration of surgery ≥ 60 min (RR 5.5), first scanned bladder volume at the Post Anesthesia Care Unit ≥250mL (RR 2.1), and age ≥ 60 years (RR 2.0). Urine production varied from 100 to 200 mL/h. Catheterization or spontaneous voiding took place approximately 4 h postoperatively. Conclusion Spinal anesthesia, longer surgery time, and older age are the main risk factors for urinary retention catheterization. Awareness of these risk factors, regularly bladder volume scanning (at least every 3 h) and using the individual maximum bladder capacity as volume threshold for urinary catheterization may avoid unnecessary urinary catheterization and will prevent bladder overdistention with the attendant risk of lower urinary tract injury.

Abstract Background: Untreated postoperative urinary retention can result in permanent lower urinary tract dysfunction and can be prevented by timely bladder catheterization. The author hypothesized that the incidence of postoperative bladder catheterization can be decreased by using the patient’s own maximum bladder capacity (MBC) instead of a fixed bladder volume of 500 ml as a threshold for catheterization. Methods: Randomized parallel-arm and single-blinded comparative effectiveness trial conducted in 1,840 surgical patients, operated under general or spinal anesthesia without an indwelling urinary catheter. Patients were randomized to either use their individual MBC (index) or a fixed bladder volume of 500 ml (control) as a threshold for postoperative bladder catheterization. Preoperatively, the MBC was determined at home by voiding in a calibrated bowl. All other bladder volumes were measured by ultrasound. Postoperatively, bladder catheterization was performed when spontaneous voiding was impossible, and the ultrasound measurement exceeded the threshold for the group in which the patient was randomized (500 or MBC). The primary outcome was the incidence of bladder catheterization. Results: The average MBC in the control group was 582 ml (±199 ml) and in the index group 611 ml (±209 ml). The incidence of catheterization decreased from 11.8% (107 of 909 patients) in the control group to 8.6% (80 of 931) in the index group (relative risk 0.73, 95% CI 0.55 to 0.96, P = 0.025). There were no adverse events in either group. Conclusions: In patients undergoing surgery under general or spinal anesthesia using the MBC rather than a fixed 500 ml threshold for bladder catheterization is a safe approach that significantly reduces the incidence of postoperative bladder catheterizations.

Objective: To compare the clean intermittent self-catheterization (CISC) with continuous indwelling catheterization (CIDC) in relieving acute urinary retention (AUR) due to benign enlargement of prostate (BEP). Materials and Methods :A total 60 patients attending in urology department of Dhaka Medical college hospital were included according to inclusion criteria ,Patients were randomized by lottery into two groups namely group –A and group –B for CISC and IDC drainage respectively . Thus total 60 patients 30 in each group completed study. Results : Most men can safely be managed as out-patients after AUR due to BPH. The degree of mucosal congestion and inflammation within the bladder was found to be lower in those using CISC and the bladder capacity in these patients was also found higher.Patients with an IDC had a high incidence of UTIs then that of patients with CISC. During the period of catheterization the incidence of UTI was 43.3% in group B in comparison to 40% in group A; before TURP 36% in group B in comparison to 10% incidence in group A.According to patient’s opinion CISC is better than IDC in the management of AUR. Experiencing bladder spasm, reporting blood in urine, management difficulties, incidence and severity of pain were less in CISC group, and the method of CISC was well accepted by patients as well as their family members. Conclusion: From the current study it may be suggested that CISC is better technique for management of AUR patient due to BPH than IDC. It can also be very helpful when surgery must be delayed or avoided due to any reasons in this group of patients. Bangladesh Journal of Urology, Vol. 21, No. 2, July 2018 p.105-110
