Accuracy of postvoid residual volumes after vaginal delivery: a prospective equivalence study to compare an automatic scanning device with transurethral catheterization

Abstract

The BladderScan® (BVI 9400) measures PVRV precisely and reliably after vaginal delivery and should be preferred over catheterization.

Recommendations and future research initiative to optimize bladder management in pregnancy and childbirth International Consultation on Incontinence ‐ Research society 2018

“…In routine clinical practice, assessment is usually limited to symptomatic postnatal women or women with risk factors for PUR. While some authors have expressed their concerns about the accuracy of 3D Doppler bladder ultrasound scan postnatally, a number of validation studies have shown that automatic scanning devices measure PVR precisely and reliably after vaginal delivery and should be preferred over catheterisation …”

“…While some authors have expressed their concerns about the accuracy of 3D Doppler bladder ultrasound scan postnatally, 45 a number of validation studies have shown that automatic scanning devices measure PVR precisely and reliably after vaginal delivery and should be preferred over catheterisation. 46,47 There is no evidence for active management of covert PUR with catheterization as this condition resolves within 4 to 7 days. 6 Regarding the treatment of overt PUR, clean intermittent catheterization (CIC) is associated with shorter duration of intervention compared with transurethral indwelling catheterization.…”

“…6 Regarding the treatment of overt PUR, clean intermittent catheterization (CIC) is associated with shorter duration of intervention compared with transurethral indwelling catheterization. 48 In the randomized control study by Mulder et al, 39,41,42,44,47,48 the duration of catheterization was not related to the initial PVR volume and the first trial without the indwelling catheter was performed 24 hours after its insertion.…”

Three-dimensional bladder ultrasonography with the BladderScan® overestimates post void residual one week after delivery

“…Regarding the latest prospective study of Mulder et all, the reliability of measuring PVR with the BladderScan ® (BVI 9400) is promising, according to a sensitivity of 85.4% and sensitivity of 85.6% with a cut-of range for PVR >500 ml directly postpartum [14]. Even though it is a methodically wise strong and large study, it also is the first which used the newer BladderScan ® (BVI 9400).…”

“…The three-dimensional bladder ultrasonography (BladderScan ® (US, using the BVI 3000 ® , Verathon, WA, USA) is most commonly used method in the Netherlands for determination of PVR in postoperative patients. However, the reliability of the BladderScan ® in the postpartum period are conflicting [1,[9], [10], [11], [12], [13], [14]].…”
