5. Study Description
Brief Summary
Chronic pelvic pain (CPP) can affect both sexes and lasts at least for 3 months. CPP in women could be due to endometrioses, ovarian cyst, colitis, etc, making the correct diagnosis important (1-3). The most prevalent reason for CPP in men is non-bacterial chronic prostatitis and in many cases they are considered equivalent to each other (4).
Chronic non-bacterial prostatitis is associated with pain in pelvic region and could be associated with other symptoms such as dysuria, myalgia, arthralgia, chronic fatigue, burning sensation in the urethra, abdominal, urine frequency, and pain after ejaculation (4-6). Chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS) is devided into two groups: III A Type (inflammatory) and III B (Non-inflammatory). The difference between the two groups is the presence of leukocytes in prostatic secretions after prostate massage, urine and semen (7,8).
In general population, the prevalence of chronic pelvic pain syndrome is about 0.5 percent because many patients do not consider their symptoms as disease, while 6.3% of people may show symptoms (9-11).
One of the most important challenges in the treatment of chronic prostatitis / chronic pelvic pain syndrome, is that its etiology is obscure and it is known as a multi-factorial syndrome. The proposed explanations are infection, psychological reasons, autoimmunity and neuro-myospasm. Hypotheses about endothelial cells defect and cardio vascular disease have also been proposed, upon which the new therapies have been based.
In duplex mapping study of prostatic vessels in two groups of healthy and chronic non-bacterial prostatitis people, it was shown that there was a significant reduction in systolic flow in prostatic arteries in people who had chronic non-bacterial prostatitis, and there was a direct association between pain and blood flow intensity, suggesting chronic ischemia as a possible cause for pain (13). Pain in prostate without significant infection is the hallmark of chronic prostatitis / chronic pelvic pain syndrome (5). In physical exam, prostate or pelvic tenderness may be observed in half of the patients.
The diagnosis of chronic prostatitis / chronic pelvic pain syndrome is challenging. No specific lab test exists for its detection. Prostate specific antigen (PSA) level, which is typically increased in acute infection, is usually normal in this condition. The diagnostic approach in these patients is based on ruling out other curable causes such as benign prostatic hyperplasia or bladder cancer (14-20).
NIH Chronic Prostatitis Symptom Index (NIH-CPSI) is used to evaluate symptom severity and response to treatment in these patients. A reduction of 4-6 points in the score is considered significant response to the treatment (21).
There is no first line treatment for patients of chronic pelvic pain syndrome. The use of anti-bacterial, alpha-blockers or anti-inflammatory drug is logical. However, if the patient does not respond, further administration is not helpful. In non-responders, combination of drugs or other non-medical methods should be considered (23-26).
As discussed earlier, blood flow reduction, ischemia and disorders in endothelium of vessels may cause pain in these patients and methods to improve blow flow may help(13,27). One of these methods is extracorporeal shockwave therapy (ESWT) which is typically used for tendonitis, acceleration in bone reunion and wound healing, improvement in muscle movements through a reduction in passive muscular tonus, increasing muscular range of motion after cerebrovascular accident (CVA), treatment of Peyronie's disease and erectile dysfunction (28-30).
Shoskes et al compared 24 chronic prostatitis patients with 11 controls in terms of vascular stiffness, indexes of increased blood flow, vasodilation and reactive vascular hyperemia, using Endo-PAT ® 2000-Machine. They showed that endothelial disorder and stiffness along with the risk of cardiovascular disorders are increased in CP/CPPS (31).
The use of ESWT for the treatment of CP/CPPS has been evaluated in a few studies. In a double-blind randomized control trial, Zimmermann et al placed 60 patients with chronic pelvic pain syndrome from chronic non-bacterial prostatitis into two groups and treated one of them in 4 sessions with a frequency of 3000 per session. The treatment group showed superior results in terms of symptom improvement(32).
In another study, Zimmermann et al followed 34 patients with chronic pelvic pain syndrome, after one, four and twelve weeks post ESWT in terms of quality of life and pain reduction. They showed that this method is useful and without any complications (33).
Considering the promising results of the cited articles along with the paucity of data in this regard we decided to perform a double-blind sham-controlled study to evaluate the effectiveness of ESWT in CP/CPPS.
Detailed Description
Eligible patients will sign an informed consent. Bacterial prostatitis will be ruled out by a 2-glass test (In this method a mid-stream urine sample is collected (10 ml of urine is discarded and the second 10 ml of urine is collected) and then prostate massage is done for a minute by Digital Rectal Exam and then another 10 ml of urine is collected.
After briefing the patients about the method and obtaining written consent from, he will be randomly allocated into either the treatment or control group.
In the first group patients will be treated by ESWT once a week for 4 weeks. (Each time 3000 impulses, with 0.25 mJouls/M2 and 3 Hertz of frequency. After each 500 pulses, the probe position will be corrected, using trans-perineal ultrasound. The used device in this study is the standars electromagnetic DUOLITH SD1- shock waves against erectile dysfunction.
In the control group, the same protocol is applied but with the probe being turned off.
The examination is performed in supine position for patient. For each patient, pelvic pain intensity considering is performed at the beginning and end of study, by VAS. Patients are considered by doctor for NIH index at the beginning and end of study.
Finally, obtained data about pain relief and change in NIH-CPSI are recorded in special profile for each patient and finally are analyzed.
