Experts’ summary:
The routine use of urodynamics (UDS) in the management
of female stress urinary incontinence (SUI) is a controversial
topic that is widely debated. Evidence from two randomized
controlled trials (RCTs) has indicated that UDS may not be a
necessary step for uncomplicated cases of SUI [1,2]. Con-
versely, many other sources, such as extensive experience
and observational studies, suggest that UDS might be
helpful in clinical decision-making and facilitate appropri-
ate patient counseling. The focus of this multidisciplinary
group of UDS experts was to consider the role and value of
UDS for female patients who are potential candidates for
SUI surgery. A modified version of the Delphi method was
used to reach a consensus viewpoint structured around five
key questions. The authors were unanimous in stating the
important role of UDS in female SUI that should not be
eclipsed by the findings in two RCTs with several biases.
Experts’ comments:
While UDS in patients with complicated characteristics
should be considered mandatory before surgery, its use for
the management of uncomplicated or “index” SUI forms is
controversial. This reflects the lack of evidence on the role of
preoperative urodynamic evaluation in improving out-
comes from continence surgery in index patients.
In our opinion, UDS is an important tool in the hands of
clinicians for collection of additional functional information
that could guide the right therapeutic choice. A simple
office-based evaluation is not sufficient to identify some
relevant issues that only UDS can detect, such as voiding
dysfunction in the absence of a significant postvoid residual
urine volume, “asymptomatic” detrusor overactivity, or a
urethral sphincter deficiency [3,4].
The well-conducted European expert consensus by
Finazzi Agrò et al has the merit of identifying many factors
that may have contributed to the increasing underuse of
UDS in female SUI. Although the group was composed of
experts who routinely use UDS in their clinical practice,
they presented objective and evidence-based opinions.
However, the lack of a standardized definition of
uncomplicated SUI might be a limitation of this consensus
paper. Therefore, a possible question for panelists could be:
What do you consider to be “uncomplicated patients”? In
the literature, there is no agreement on the definition of
uncomplicated SUI, in particular among the different
international guidelines [5]. In this scenario, it is difficult
to compare the different studies and recommendations
available.
