Chronic Pelvic Pain:
Is It Time for an Algorithmic
Approach?
Chronic pelvic pain (CPP) is a ubiquitous, yet poorly
defined condition that is described in terms of the ana-
tomic area from which the presumed pathophysiologic
pain generator originates. However, the pelvis contains
multiple organ systems with complex overlapping
innervation and integrated function, so it is often diffi-
cult to identify a single contributor to the pathogenesis
or maintenance of CPP. The search for a specific etiol-
ogy leads the 15 million sufferers from CPP to seek
evaluation with multiple specialists over time, at signif-
icant cost to both the patient and the healthcare sys-
tem. In addition to this problem of misdiagnosis (or
lack of precise diagnosis), there are no clear treatment
strategies for the condition. Further, even when a diag-
nosis is suggested by characteristic pathologic features,
for example, interstitial cystitis, comparative effective-
ness trials of various pharmacologic or procedural
therapies are few.1
In this issue of Pain Practice, Apte et al.2 have per-
formed an extensive review of the condition known as
CPP. As described by the authors, the comprehensive
evaluation and diagnosis of CPP are time–consuming
and may involve invasive physical examination tech-
niques or biomechanical maneuvers not familiar to
many practitioners. Thus, in common practice,
patients receive treatments that vary by both geo-
graphic location as well as the specialty of origin of
the treating physicians. Similar to the recommenda-
tions of Nelson et al.,3 we agree the treatment of pelvic
pain should involve a multidisciplinary approach and
should ideally involve evaluation and treatment only
by physicians, physical therapists, and psychologists
well-versed in the complex biopsychosocial and patho-
physiologic contributors to the development and main-
tenance of CPP.
The available data suggest that a common feature
of CPP is primary biomechanical dysfunction in the
pelvic floor, pelvic ring, or associated stabilizing lum-
bar or abdominal structures. This can also be second-
ary to neuropathic pain generators and/or psychologic
factors. As described by Apte et al.,2 a thorough evalu-
ation and examination is key to determining the best
treatment strategy. However, many of the proposed
and potentially effective treatment modalities are
already inconsistently reimbursed (pelvic floor PT and
cognitive behavioral therapy), not traditionally reim-
bursed (peripheral nerve stimulation and pulsed radio-
frequency ablation), or currently in danger of lost
reimbursement (sacroiliac joint injections).4–7
In light of this, it is important to note that, even
given the preponderance of data supporting pharmaco-
logic, interventional, rehabilitative, and cognitive ther-
apies for CPP, no stepwise validated approach exists
for the management of CPP. In the absence of compel-
ling, robust, comparative effectiveness data with vali-
dated outcomes, reimbursements for logical and likely
effective therapies may continue to suffer, further com-
pounding the problem.
Subspecialty-specific algorithmic approaches to pel-
vic pain are already described in the gynecologic or
urologic literature, and advocate pharmacologic, hor-
monal, and surgical therapy of defined pain-generat-
ing disease processes.1,8–10 However, like many
chronic disabling pain syndromes, CPP may be the
result of an incompletely understood dysfunction in
peripheral and/or central neural processing. As our
understanding of neural plasticity and central sensiti-
zation evolves over time, CPP may become a disease
unto itself, with persistent pain even when the origi-
nal inciting pathophysiologic process is understood.11
Therefore, it is critical that timely interventions are

rationally introduced when the process can be inter-
rupted or abated.
Algorithms have been published for evaluation and
treatment of headaches, fibromyalgia, and pain of
spinal origin, for example,12–16 yet multidisciplinary
approaches to the management of CPP by pain practi-
tioners has largely been limited to descriptive reports
of injections and neuromodulatory techniques.17–21
One of the few algorithms for the management of CPP
was published by De Andres in 2003,22 was specific to
coccydynia, and has yet to be validated. Others, like
Ducic et al.’s23 algorithm for the treatment of postsur-
gical incisional groin pain, are specific in scope and
discuss only medical and surgical options for manage-
ment. Nelson et al.’s article is an excellent comprehen-
sive summary of the available literature with regard to
the treatment of CPP in women, but does not propose
a stepwise treatment strategy for pain practitioners,
and does not address CPP in men.
What is critically needed, both from the standpoint
of the urgent public health and economic needs of the
nation, and our goal as physicians devoted to the elim-
ination of suffering, is to develop and implement evi-
dence-based multidisciplinary treatment algorithms for
both male and female patients with undifferentiated
CPP. Concomitant with these algorithms, we must
develop the means to critically assess clinical and func-
tional outcomes. The use of IMMPACT recommenda-
tions where several facets of disease (pain intensity,
functionality, depression, etc.) can be assessed longitu-
dinally may be a logical start.24 There is also a critical
need for ongoing comparative effectiveness research
and resource utilization assessments to ensure the
availability of clinically effective, systematically viable
options for patients with CPP.
