CONTEXT These guidelines were prepared on behalf of the European Association of Urology (EAU) to help urologists assess the evidence-based management of chronic pelvic pain (CPP) and to incorporate the recommendations into their clinical practice. OBJECTIVE To revise guidelines for the diagnosis, therapy, and follow-up of CPP patients. EVIDENCE ACQUISITION Guidelines were compiled by a working group and based on a systematic review of current literature using the PubMed database, with important papers reviewed for the 2003 EAU guidelines as a background. A panel of experts weighted the references. EVIDENCE SYNTHESIS The full text of the guidelines is available through the EAU Central Office and the EAU Web site (www.uroweb.org). This article is a short version of the full guidelines text and summarises the main conclusions from the guidelines on the management of CPP. CONCLUSIONS A guidelines text is presented including chapters on chronic prostate pain and bladder pain syndromes, urethral pain, scrotal pain, pelvic pain in gynaecologic practice, neurogenic dysfunctions, the role of the pelvic floor and pudendal nerve, psychological factors, general treatment of CPP, nerve blocks, and neuromodulation. These guidelines have been drawn up to provide support in the management of the large and difficult group of patients suffering from CPP.

CONTEXT The increasing body of evidence and number of potential indications for the use of botulinum neurotoxins (BoNTs) in the lower urinary tract (LUT) underlines the pressing need for evidence-based guidelines. OBJECTIVE A European expert panel consensus conference was convened with the main aim of evaluating the evidence and clinical considerations for the use of BoNTs in the treatment of urologic and pelvic-floor disorders and to propose relevant recommendations. EVIDENCE ACQUISITION The quality of evidence from fully published English-language literature in the PubMed and EMBASE databases was assessed using the European Association of Urology (EAU) levels of evidence (LoE). Recommendations were graded and approved by a unanimous consensus of the panel. EVIDENCE SYNTHESIS The use of botulinum neurotoxin type A (BoNTA) is recommended in the treatment of intractable symptoms of neurogenic detrusor overactivity (NDO) or idiopathic detrusor overactivity (IDO) in adults (grade A). Caution is recommended in IDO because the risk of voiding difficulty and duration of effect have not yet been accurately evaluated. Repeated treatment can be recommended in NDO (grade B). The depth and location for bladder injections should be within the detrusor muscle outside the trigone (grade C). Dosage in children should be determined by body weight, with caution regarding total dose if also being used for treatment of spasticity, and minimum age (grade B). Existing evidence is inconclusive for recommendations in neurogenic detrusor-sphincter dyssynergia, bladder pain syndrome, prostate diseases, and pelvic-floor disorders. The use of BoNTA in the LUT with the current dosages and techniques is considered to be safe overall (grade A). CONCLUSIONS The consensus committee recommends larger placebo-controlled and comparative trials to evaluate the efficacy of single and repeat injections, the duration of effect, the optimal dosage and injection technique, the timing for repeat injection, and the short- and long-term safety of the treatment in LUT and pelvic-floor disorders.

BACKGROUND We examined, for the first time in a prospective study, the histological changes in the urothelium and suburothelium of patients with neurogenic (NDO) or idiopathic detrusor overactivity (IDO) after one or repeat treatments with intradetrusor BoNTA. METHODS Flexible cystoscopic bladder biopsies were obtained from patients with urodynamically proven intractable spinal NDO or IDO before and 4 and 16 wk after one or repeat treatments with intradetrusor injections of BOTOX1 (NDO 300 U, IDO 200 U). Specimens were stained for haematoxylin-eosin and analysed blindly for inflammatory changes, fibrosis, hyperplasia, and dysplasia in the urothelium and suburothelium. Statistical comparisons were significant at p values less than 0.05. RESULTS Signs of chronic inflammation were found in 59.1% of baseline biopsies (65.6% of NDO vs. 50% of IDO, p=0.049), 67.6% of post-first biopsies and 86.4% after repeat injections. The two groups were comparable for degree of baseline inflammation, which did not change significantly after first injection and up to 16 wk after a third injection. Mild fibrosis was found in 2.2% of biopsies examined, equally before and after treatment, but not after repeat injections. No dysplasia or hyperplasia was identified. Eosinophils were identified more frequently in biopsies taken after repeat injections compared with the post-first injection and baseline biopsies (chi2=8.23, p=0.018). No difference existed between NDO and IDO bladders. CONCLUSIONS BoNTA injections do not appear to be producing significant inflammatory changes, fibrosis, or dysplastic changes in human bladder urothelium/suburothelium after a single injection and in a limited number of repeat treatment biopsies. The presence of eosinophils might be treatment-related, because they were mostly found in post-treatment biopsies.

BACKGROUND An increasing body of evidence suggests a possible role of suburothelial myofibroblasts (MFs) in bladder mechanosensation and in the pathophysiology of detrusor overactivity (DO). OBJECTIVE To determine whether markers of MFs, including gap junction protein connexin43 (Cx43) and c-kit have altered immunohistochemical expression in the suburothelium of patients with neurogenic DO (NDO) or idiopathic DO (IDO) and whether this is affected by successful treatment of DO with botulinum neurotoxin type A (BoNTA). DESIGN, SETTING, AND PARTICIPANTS Patients with NDO (n=10) or IDO (n=11) were treated in a single-centre, open-label study of intradetrusor BoNTA injections. Control tissue was obtained from 10 patients undergoing pelvic-floor repair procedures who had no overactive bladder (OAB) symptoms. This study is registered with ClinicalTrials.gov, number NCT00662064. INTERVENTIONS Bladder biopsies performed with flexible cystoscopes were obtained from control subjects and from NDO and IDO patients before BoNTA treatment and at 4 wk and 16 wk after treatment. They were studied with quantitative immunofluorescence using antibodies to connexin 43 (Cx43), vimentin, and c-kit. MEASUREMENTS Differences in Cx43, vimentin, and c-kit immunoreactivity between control subjects and NDO or IDO patients (primary outcomes). Changes in NDO or IDO, Cx43 immunoreactivity, and c-kit immunoreactivity after BoNTA treatment (secondary outcomes). RESULTS AND LIMITATIONS Cx43 immunoreactivity was increased in both IDO and NDO patients compared to controls, but remained unchanged after BoNTA treatment. C-kit immunoreactivity was similar in NDO/IDO patients and controls and remained unchanged after BoNTA treatment. CONCLUSIONS Increased gap junction formation in the suburothelium has been demonstrated in biopsies from humans with DO. It is hypothesised that this change could have a significant role in the pathogenesis of the detrusor abnormality. Successful treatment of NDO or IDO does not appear to be associated with changes in the expression of Cx43 or c-kit on suburothelial MFs.

PURPOSE We studied the effect of repeat detrusor botulinum neurotoxin type A injections on urinary symptoms, health and quality of life in patients with refractory neurogenic detrusor overactivity secondary to multiple sclerosis. MATERIALS AND METHODS This was a prospective, open label, single center study in 137 patients with multiple sclerosis treated with detrusor injections of botulinum neurotoxin type A with observations made from 2002 to 2009. A minimally invasive outpatient technique was used for injection. Patients were asked to contact the department if and when they required repeat treatment. Recurrent detrusor overactivity was then identified on urodynamics. The primary outcomes measured were the change in symptoms and quality of life, as assessed by the Urogenital Distress Inventory, Incontinence Impact Questionnaire and EuroQol-5 Dimensions questionnaires (www.ion.ucl.ac.uk/departments/repair/themes/uroneurology) before and 4 weeks after botulinum treatment. Continence status, the need for clean intermittent self-catheterization before and after injections, and interinjection intervals were also analyzed. RESULTS Mean Urogenital Distress Inventory and Incontinence Impact Questionnaire 7 scores showed considerable improvement 4 weeks after each treatment even when repeated 6 times. Almost all patients relied on clean intermittent self-catheterization after treatment. Before the first treatment 83% of patients were incontinent but 4 weeks after the first treatment 76% (104 of 137) became completely dry. This efficacy was sustained with repeat injections. The median interval between re-treatments remained constant at 12 to 13 months. CONCLUSIONS Repeated detrusor botulinum neurotoxin type A injections for refractory neurogenic detrusor overactivity in patients with multiple sclerosis have a consistent effect on bladder control, resulting in sustained improvement in quality of life.

PURPOSE We documented the effects of intradetrusor injections of botulinum neurotoxin type A (Botox(R)) for refractory idiopathic detrusor overactivity so that prospective patients maybe properly informed about possible improvement in quality of life, the duration of interinjection intervals and the risk of clean intermittent self-catheterization. MATERIALS AND METHODS A total of 81 consecutive patients with refractory idiopathic detrusor overactivity treated with intradetrusor injections of 200 U botulinum neurotoxin type A at 20 sites per injection course were evaluated in this prospective, nonrandomized, open label cohort study. The primary outcome was changes in quality of life, as assessed by the short form of the Urogenital Distress Inventory and the Incontinence Impact Questionnaire before and after treatment. Secondary outcomes were the interinjection interval and the need for clean intermittent self-catheterization. RESULTS After intradetrusor botulinum neurotoxin type A injections there was significant improvement in quality of life, which was sustained after repeat injections. Mean Urogenital Distress Inventory and Incontinence Impact Questionnaire scores decreased from 56 to 26 and 59 to 21 after injection 1 in 81 patients, from 52 to 30 and 51 to 24 after injection 2 in 24, from 40 to 19 and 43 to 17 after injection 3 in 13, from 44 to 17 and 61 to 15 after injection 4 in 6 and from 51 to 17 and 63 to 14 after injection 5 in 4, respectively. The median interinjection interval was 15, 12, 14 and 13 months between injections 1 and 2, 2 and 3, 3 and 4, and 4 and 5, respectively. Considering a post-void residual urine of greater than 100 ml with lower urinary tract symptoms as the indication for clean intermittent self-catheterization, the overall clean intermittent self-catheterization rate after treatment was 43%. CONCLUSIONS Intradetrusor botulinum neurotoxin type A injections for refractory idiopathic detrusor overactivity significantly improved quality of life. This effect was sustained after repeat injection. More than 2 of 5 patients with refractory idiopathic detrusor overactivity required clean intermittent self-catheterization after botulinum neurotoxin type A injections and all prospective patients should be informed about this.
