One of the standout features is pain relief on bladder emptying \n 6 \n . Symptoms of interstitial cystitis are commonly found in patients with chronic pelvic pain. In three observational studies of women with pelvic pain who sought treatment, around 38–84% had symptoms suggestive of interstitial cystitis \n 7 - 9 \n . The diagnosis is exclusionary, which sometimes delays the implementation of treatment.\nMyofascial pain can arise from changes in the musculoskeletal system. Most patients with this etiology for pain have trigger points identified as areas of muscle band contracture that are very painful on palpation. It is believed that the appearance of trigger points may also be associated with pelvic misalignment, secondary to postural changes due to the effect of pain with its perpetuation. That is, they can be both a consequence and a cause of chronic pelvic pain \n 3 \n .\nIrritable bowel syndrome is a disease that alters gastrointestinal functionality and is mostly characterized by abdominopelvic pain associated with changes in the frequency and formation of stool. It most often presents in relapses and remissions and is more common in patients with psychiatric comorbidities. Although there is no complete understanding of the pathophysiology, it is known that there is a hyperstimulus in the central nervous system with feedback of symptoms \n 10 \n .\nPelvic varicose veins also represent a concern in the workup in patients with pelvic pain, as there is a direct relationship between pelvic pain and venous compression syndromes that may promote pelvic congestion. This presents as a hard type of pain with worsening at the end of the day and associated lower limb edema in most cases \n 11 \n .\nCompressive syndromes may be related to the presence of arteriovenous malformations that hinder the venous return of the female reproductive system, such as Cockett's syndrome (left common iliac vein is compressed between the right common iliac artery and spine) and Nutcracker syndrome (left renal vein and superior mesenteric artery and aorta) \n 11 \n .\nFor the diagnosis, the use of magnetic resonance angiography of the abdomen and pelvis with contrast is necessary, and the treatment requires expertise in the application of stents by interventional radiology \n 11 \n .\nAdenomyosis is also a benign gynecological disease of high prevalence and may or may not be associated with endometriosis, which is considered an important cause of chronic pelvic pain with symptoms that vary according to the degree of involvement \n 1 , 3 \n . It evolves from cyclical pain such as dysmenorrhea, which may or may not exacerbate menstrual blood flow, promote dyspareunia and infertility, and also be considered a cause of chronic pelvic pain \n 3 \n .\nHormonal treatment with progestogens has good results, but it is restricted to women without reproductive desire or with constituted offspring. In cases of pain refractory to medical treatment and without reproductive desire, total hysterectomy can be an excellent alternative, but it is important to make it clear that in cases where there is an association with deep endometriosis, if it is also not removed during surgery, there may be the persistence of all pain symptoms \n 2 , 12 \n .\nAccording to epidemiological studies, endometriosis represents around 50% of the causes of chronic female pelvic pain and is therefore considered the main cause of pelvic pain \n 12 \n . In the last 20 years, we have been following the evolution of non-invasive diagnostic imaging through ultrasound with bowel preparation and magnetic resonance imaging of cases of deep peritoneal endometriosis \n 13 \n .\nDespite the concept that there is no direct relationship between the degree of endometriosis involvement and the level of pain presented by the patient, information on the presence of the disease through imaging tests is considered a positive predictor that justifies the cause of pain. In these cases, considering the absence of some conditions such as reproductive desire, signs of intestinal or ureteral subocclusion, presence of large-volume endometriomas, appendix, and ileocecal endometriosis, clinical treatment may be chosen instead of immediate surgical treatment \n 12 , 13 \n , and surgical treatment is restricted to cases of refractoriness to clinical treatment and to the absolute indications previously mentioned.\nSurgical treatment, on the other hand, is still a great challenge because deep endometriosis surgery is highly complex due to the distortion of the anatomy, which can lead to infiltration of the retroperitoneum toward vital structures such as the ureter, large vessels, and autonomic and somatic pelvic innervation, in addition to intestinal involvement (rectum, sigmoid, ileum, cecum, and appendix), bladder, and diaphragmatic \n 12 - 14 \n . Therefore, there is a need for a multidisciplinary team for complete resection of the disease. For this reason, there is a very large percentage of patients who undergo suboptimal surgeries with the persistence of the disease and therefore the persistence of symptoms.\nThe use of hormonal therapy in the postoperative period has been pointed out as a fundamental tool in the attempt to prevent the secondary recurrence of lesions and symptoms \n 14 \n .\nAnother less frequent cause, but which we cannot rule out, is pelvic-perineal pain related to damage to the pudendal nerve that can be caused by accidents, bruising, or more often by stretching of the nerve associated with childbirth, pelvic organ prolapse, sports such as cycling, or even patients who remain seated for long periods \n 15 \n . The pain pattern is often associated with shock, paresthesia, and burning sensations and can be relieved with changes in positioning that tend to decompress the nerve root \n 3 \n . Another therapeutic alternative is imaging-guided infiltration of the Alcock canal with local anesthetics by imaging \n 15 \n .\nFemale chronic pelvic pain is indeed a huge challenge for the gynecologist. The latter should be aware of several possible etiologies, both gynecological and non-gynecological, and may require expertise in diagnosis that goes beyond organic pain of organs located in the pelvis and multidisciplinary team effort for the best treatment in the search for long-lasting results.","source_license":"CC0","license_restricted":false}
