“…The ultrasound-estimated bladder weight was then calculated in 92 healthy children with a specific bladder volume formula for each category of bladder shape. [26] A similar correlation between bladder weight and age was found (r = 0.78, P <0.05) and a simpler formula was proposed: Bladder weight = Age + 8.4.…”

Objectives:Measurement of bladder weight using ultrasound estimates of bladder wall thickness and bladder volume is an emerging clinical measurement technique that may have a role in the diagnosis of lower urinary tract dysfunction. We have reviewed available literature on this technique to assess current clinical status.Methods:A systematic literature search was carried out within PubMed and MedLine to identify relevant publications. These were then screened for relevance. Preliminary results from our clinical experiments using the technique are also included.Results:We identified 17 published papers concerning the technique which covered clinical studies relating ultrasound-estimated bladder wall thickness to urodynamic diagnosis in men, women, and children together with change in response to treatment of bladder outlet obstruction. The original manual technique has been challenged by a commercially available automated technique.Conclusion:Ultrasound-estimated bladder weight is a promising non-invasive technique for the categorization of storage and voiding disorders in both men and women. Further studies are needed to validate the technique and assess accuracy of diagnosis.

“…22 Although many authors have claimed BWT and DWT are very helpful in diagnosing BOO but there are few limitations. Some authors rightfully claim that BWT is dependent on the degree of bladder filling which leads to difference in calculations even of the same patient at different times 23 . For this reason, BWT as well as DWT require standardization.…”

Objectives: Our objective was determination of the correlation between mean bladder wall thickness and mean IPSS in BPH diagnosed patients. Study Design: Cross sectional study. Setting: Department of Urology & Renal Transplantation, Punjab Medical College / Allied Hospital, Faisalabad. Period: Six months from 01-04-2016 to 30-09-2016. Material & Methods: Total 70 patients were enrolled for study from outpatient department of Urology, AHF. IPSS was calculated and recorded. Transabdominal ultrasound KUB was done to measure bladder wall thickness. Urine complete examination and culture was done to rule out UTI. Existence of bladder tumor was ruled out by previous history and ultrasonography. The data was collected on a Proforma by myself. Results: Out of 70 enrolled cases, 47.14% (n=33) were aged 50-60 years whereas 52.86% (n=37) were 61-70 years of age. Mean age was calculated as 61.27+5.31 years. Mean Bladder Wall thickness was 3.64+0.72 and IPSS was calculated to be 12.84+2.79 (r0.9056). Correlation between mean bladder wall thickness and mean IPSS in patients having benign prostatic hyperplasia was calculated as significant. Conclusion: In patients suffering from BOO due to BPH, we have found a very strong positive correlation between mean IPSS and mean BWT. However, bigger studies using standardized techniques are required to establish this fact.

“…Bladder wall thickness has also been shown to decrease with bladder filling. 17 Kojima et al demonstrated a significant correlation between the ultrasound-estimated bladder weight of 10 adult cadaveric bladders and the actual bladder weight (r = 0.970, P < .0001) 18 with reproducibility shown over volumes ranging between 100 and 300 mL. One reason for this rise in bladder weight with age in the spina bifida population is that detrusor sphincter dyssynergia results in high-pressure contractions which when combined with failure to empty places the myocytes and fibroblasts of the bladder wall on stretch.…”

Purpose-This retrospective study was designed to evaluate which lower urinary tract ultrasound parameter(s) could predict the results of invasive urodynamic testing which are the current reference standard in the evaluation of bladder dysfunction in children with spina bifida.Materials and Methods-Fifty eight children with spina bifida undergoing video urodynamic evaluation and a renal bladder ultrasound as their standard of care were evaluated. Quantitative and qualitative ultrasound parameters were then correlated with the videourodynamic study results which served as the reference standard.Results-For bladders with ending storage pressures above 15 cm H 2 O, there were increases in these ultrasound measured parameters: 1) bladder mass (P = .00019), 2) bladder/body mass ratio (P = .0059), and 3) wall thickness (P = .01). We defined the storage cost as the final storage pressure divided by the percentage of expected bladder capacity attained. These data were analyzed to compute receiver operating curves with assuming end storage pressures cutoff points of 15, 20, 30, and 40 cm H 2 O. The optimal area under the curve was found for a bladder weight of 65 g and a pressure cutoff of 30 cm H 2 O with a sensitivity of 75% with a specificity of 84%.Conclusion-Bladder weight is independent of luminal volume, can be normalized to body weight, and may serve as a clinically valuable tool for noninvasive screening to define a subset of patients with neurogenic bladder with a higher likelihood of having abnormal videourodynamic results.
