Abstract
PURPOSE OF REVIEW Pelvic floor disorders can present with lower urinary tract symptoms, bowel, sexual dysfunction, and/or pain. Symptoms of pelvic muscle spasm (nonrelaxing pelvic floor or hypertonicity) vary and can be difficult to recognize. This makes diagnosis and management of these disorders challenging. In this article, we review the current evidence on pelvic floor spasm and its association with voiding dysfunction. RECENT FINDINGS To distinguish between the different causes of voiding dysfunction, a video urodynamics study and/or electromyography is often required. Conservative measures include patient education, behavioral modifications, lifestyle changes, and pelvic floor rehabilitation/physical therapy. Disease-specific pelvic pain and pain from pelvic floor spasm needs to be differentiated and treated specifically. Trigger point massage and injections relieves pain in some patients. Botulinum toxin A, sacral neuromodulation, and acupuncture has been reported in the management of patients with refractory symptoms. SUMMARY Pelvic floor spasm and associated voiding problems are heterogeneous in their pathogenesis and are therefore often underrecognized and undertreated; it is therefore essential that a therapeutic strategy needs to be personalized to the individual patient's requirements. Therefore, careful evaluation and assessment of individuals using a multidisciplinary team approach including a trained physical therapist/nurse clinician is essential in the management of these patients.

Abstract
Cannabinoids have been shown to exert analgesic and anti-inflammatory effects, and the effects of cannabinoids are mediated primarily by cannabinoid receptors 1 and 2 (CB1and CB2). Both CB1 and CB2 are present in bladders of various species, including human, monkey, and rodents, and it appears that CB2 is highly expressed in urothelial cells. We investigated whether treatment with the CB2 agonist GP1a alters severity of experimental cystitis induced by acrolein and referred mechanical hyperalgesia associated with cystitis. We also investigated whether the mitogen-activated protein kinases (MAPK), ERK1/2, p38, and JNK are involved in the functions of CB2. We found that treatment with the selective CB2 agonist GP1a (1-10 mg/kg, ip) inhibited the severity of bladder inflammation 3 h after intravesical instillation of acrolein in a dose-dependent manner, and inhibition reached significance at a dose of 10 mg/kg (P < 0.05). Treatment with GP1a (10 mg/kg) inhibited referred mechanical hyperalgesia associated with cystitis (P < 0.05). The inhibitory effects of the CB2 agonist were prevented by the selective CB2 antagonist AM630 (10 mg/kg, sc). We further demonstrated the inhibitory effects of CB2 appear to be at least partly mediated by reducing bladder inflammation-induced activation of ERK1/2 MAPK pathway. The results of the current study indicate that CB2 is a potential therapeutic target for treatment of bladder inflammation and pain in patients.

Abstract
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.

Abstract
Mast cells have been shown to play a role in development and persistence of various inflammatory bladder disorders. Mast cell-derived tryptase specifically activates protease-activated receptor-2 (PAR-2), and PAR-2 is known to be involved in inflammation. We investigated whether mast cells participate in increase of cyclooxygenase-2 (COX-2) protein abundance in urothelium/suburothelium of bladders of mice subsequent to cyclophosphamide (CYP)-induced bladder inflammation. We also used primary cultures of human urothelial cells to investigate cellular mechanisms underlying activation of PAR-2 resulting in increased COX-2 expression. We found that treatment of mice with CYP (150 mg/kg ip) increased COX-2 protein abundance in bladder urothelium/suburothelium 3, 6, and 24 h after CYP (P < 0.01), and increased COX-2 protein abundance was prevented by treatment of mice with the mast cell stabilizer sodium cromolyn (10 mg/kg ip) for 4 consecutive days before CYP treatment. Incubation of freshly isolated mouse urothelium/suburothelium with a selective PAR-2 agonist, 2-furoyl-LIGRLO-amide (3 microM), also increased COX-2 protein abundance (P < 0.05). We further demonstrated that 2-furoyl-LIGRLO-amide (3 microM) increased COX-2 mRNA expression and protein abundance in primary cultures of human urothelial cells (P < 0.01), and the effects of PAR-2 activation were mediated primarily by the ERK1/2 MAP kinase pathway. These data indicate that there are functional interactions among mast cells, PAR-2 activation, and increased expression of COX-2 in bladder inflammation.

Abstract
Pituitary adenylate cyclase-activating peptide (PACAP) peptides are expressed in micturition pathways, and PACAP expression is regulated by urinary bladder inflammation. Previous physiological studies have demonstrated roles for PACAP27 and PACAP38 in detrusor smooth muscle (DSM) contraction and a PAC1 receptor antagonist reduced cyclophosphamide (CYP)-induced bladder hyperreflexia. To gain insight into PACAP signaling in micturition and regulation with cystitis, receptor characterization by real-time quantitative polymerase chain reaction and physiological assays were performed. PACAP receptors were identified in tissues of rat micturition pathway, including DSM, urothelium (U), and dorsal root ganglia (DRG) after acute (4 h), intermediate (48 h) or chronic (8 days) CYP-induced cystitis. PAC1 messenger RNA expression significantly (p < or = 0.05) increased in U and DSM after 48 h and chronic CYP-induced cystitis after an initial decrease at 4 h. VPAC1 and VPAC2 transcripts increased in U and DSM after acute and intermediate CYP-induced cystitis followed by a decrease in VPAC2 expression with chronic cystitis. Application of PACAP27 (100 nM) to cultured urothelial cells evoked adenosine triphosphate (ATP) release that was blocked by the PAC1 specific antagonist, M65 (1 microM). PACAP38 (100 nM) also evoked ATP release from cultured urothelial cells, but ATP release was less than that observed with PACAP27. PACAP transcripts were increased in the U with intermediate and chronic cystitis, whereas vasoactive intestinal polypeptide (VIP) expression in both tissues was very low and showed no regulation with cystitis. Regulation of PACAP, galanin, and substance P transcripts expression was observed in lumbosacral DRG, but no regulation for VIP was observed. The current data demonstrate PACAP and PAC1 regulation in micturition pathways with inflammation and PACAP-mediated ATP release from urothelium.

Abstract
AIMS Several mechanisms that are involved in acute rat bladder nociception were examined. The nociceptive response was measured by analyzing both cardiovascular and visceromotor reflex responses to urinary bladder distension. The contributions of micro-opioid receptor, kappa-opioid receptor, sodium channels, muscarinic receptors, and cyclooxygenase, were explored with morphine, U50,488, mexiletine, oxybutynin, and naproxen, respectively. METHODS Female Sprague-Dawley rats were acutely instrumented with jugular venous, carotid arterial, and bladder cannulas. Needle electrodes were placed directly into the abdominal musculature to measure myoelectrical activity subsequent to repeated phasic urinary bladder distension (60 mmHg for 20 sec in 3 min intervals) under 1% isoflurane. Drugs were administered by i.v. bolus injection 2 min prior to distension. RESULTS The analgesics morphine (ID50 0.69 mg/kg), U50,488 (1.34 mg/kg), and mexiletine (2.60 mg/kg) significantly inhibited the visceromotor reflex response to noxious urinary bladder distension. Oxybutynin also attenuated reflex responses to noxious urinary bladder distension to 41% of the maximal pressor response and 32% of the control visceromotor reflex response (3.01 and 5.05 mg/kg), respectively, indicating a role of muscarinic receptors in bladder nociception. Naproxen did not attenuate the pressor response, but moderately inhibited visceromotor reflex to 45% of control at 30 mg/kg (P < 0.05). CONCLUSIONS Current results using the rat urinary bladder distension model are consistent with previous research demonstrating a role of the analgesics (morphine, U50,488, and mexiletine) in the inhibition of visceral nociceptive transmission. The utility of the reflex responses to urinary bladder distension may provide a method useful to examine mechanisms which target the bladder sensory pathway.

Abstract
UNLABELLED Nitric oxide (NO) has previously been shown to be a marker for inflammatory disorders in the bladder. We investigated if the measurement of NO can be used to evaluate the treatment response in classic interstitial cystitis (IC). MATERIALS AND METHODS A total of 15 patients diagnosed with classic IC were included. The patients were treated with oral prednisolone for 8 weeks. We evaluated patient symptoms/problems with the IC index, and we measured NO formation in the bladder. RESULTS Seven patients were classified as responders with a 4 point or more decrease in symptom score after 8 weeks of treatment. In this group the mean symptom score was +/- SEM decreased from 15 +/- 1 to 7 +/- 2 at the end of therapy (p <0.05). The problem score was also significantly reduced. Responders showed a clear decrease in bladder NO. The 8 nonresponders did not show any improvement in symptom/problem score and there was no change in bladder NO during steroid treatment. Furthermore, the study showed a statistically significant correlation between changes in symptom/problem score and changes in luminal bladder NO in each patient. CONCLUSIONS The study shows that NO can be used not only to measure inflammation in patients with IC, but also to evaluate objectively the treatment response in individuals. This makes NO formation a useful marker in the assessment of classic interstitial cystitis.

Abstract
Pituitary adenylate cyclase activating polypeptide (PACAP) peptides are expressed and regulated in sensory afferents of the micturition pathway. Although these studies have implicated PACAP in bladder control, the physiological significance of these observations has not been firmly established. To clarify these issues, the roles of PACAP and PACAP signaling in micturition and cystitis were examined in receptor characterization and physiological assays. PACAP receptors were identified in various tissues of the micturition pathway, including bladder detrusor smooth muscle and urothelium. Bladder smooth muscle expressed heterogeneously PAC(1)null, PAC(1)HOP1, and VPAC(2) receptors; the urothelium was more restricted in expressing preferentially the PAC(1) receptor subtype only. Immunocytochemical studies for PAC(1) receptors were consistent with these tissue distributions. Furthermore, the addition of 50-100 nM PACAP27 or PACAP38 to isolated bladder strips elicited transient contractions and sustained increases in the amplitude of spontaneous phasic contractions. Treatment of the bladder strips with tetrodotoxin (1 muM) did not alter the spontaneous phasic contractions suggesting direct PACAP effects on bladder smooth muscle. PACAP also increased the amplitude of nerve-evoked contractions. By contrast, vasoactive intestinal polypeptide had no direct effects on bladder smooth muscle. In a rat cyclophosphamide (CYP)-induced cystitis paradigm, intrathecal or intravesical administration of PAC(1) receptor antagonist, PACAP6-38, reduced cystitis-induced bladder overactivity. In summary, these studies support roles for PACAP in micturition and suggest that inflammation-induced plasticity in PACAP expression in peripheral and central micturition pathways contribute to bladder dysfunction with cystitis.

Abstract
Alterations in the expression of the neuropeptide, galanin, were examined in micturition reflex pathways of rat after cyclophosphamide (CYP)-induced cystitis of variable duration: acute (4 h), intermediate (48 h), or chronic (10 days). In control animals, galanin expression was present in specific regions of the gray matter in the rostral lumbar and caudal lumbosacral spinal cord, including: (1) the dorsal commissure (DCM); (2) superficial dorsal horn; (3) the regions of the intermediolateral cell column (L1-L2) and the sacral parasympathetic nucleus (SPN, L6-S1); and (4) the lateral collateral pathway (LCP) in lumbosacral spinal segments. Densitometry analysis demonstrated significant decreases (P< or =0.01) in galanin immunoreactivity (IR) in these regions of the L1-S1 spinal cord after acute or intermediate CYP-induced cystitis. In contrast, increases (P< or =0.01) in galanin-IR were observed in the DCM, SPN, or LCP regions in the L6-S1 spinal segments in rats with chronic cystitis. No changes in the number of galanin-immunoreactive cells were observed in the L1-S1 dorsal root ganglia (DRG) after CYP-induced cystitis of any duration. A small percentage of bladder afferent cells (Fast-blue-labeled) in the DRG expressed galanin-IR in control rats; this was not altered with cystitis. Galanin-IR was observed encircling DRG cells after chronic cystitis. These changes may contribute to urinary bladder dysfunction, altered sensation, and referred somatic hyperalgesia after cystitis.

Abstract
Interstitial cystitis (IC) is a debilitating chronic inflammatory disorder of the bladder. It affects predominantly middle-aged Caucasian women. The diagnosis, made from the combination of symptoms, cystoscopic findings and bladder biopsies, is often delayed in the gynaecology setting because of a low index of suspicion. The pathophysiology is incompletely understood, although mast cell activation, altered bladder epithelial permeability and sensory afferent nerve up-regulation are thought to play key roles. Recent theories include the role of an antiproliferative factor. A wide assortment of therapies is available and many more are under trial. Until the causes and pathogenesis of IC are unraveled, mainstream medical treatment will remain palliative and cystectomy with urinary diversion, the only potential cure. In addition to our long experience on managing this disorder, we present a comprehensive review of the current thoughts on the aetiology and management of IC.

Abstract
The purpose of this study was to determine the role of cyclooxygenase-2 (COX-2) and its metabolites in lower urinary tract function after induction of acute (4 h), intermediate (48 h), or chronic (10 day) cyclophosphamide (CYP)-induced cystitis. Bladders were harvested from euthanized female rats for analyses. Conscious cystometry was used to assess the effects of a COX-2-specific inhibitor, 5,5-dimethyl-3-(3-fluorophenyl)-4-(4-methylsulfonyl)phenyl2(5H)-furanone (DFU, 5 mg/kg sc), a disubstituted furanone, in CYP-induced cystitis. COX-2 mRNA was increased in inflamed bladders after acute (12-fold) and chronic (9-fold) treatment. COX-2 protein expression in inflamed bladders paralleled COX-2 mRNA expression. Prostaglandin D2-methoxime expression in the bladder was significantly (P < or = 0.01) increased in acute (3-fold) and chronic (5.5-fold) cystitis. Prostaglandin E2 was significantly (P < or = 0.01) increased (2-fold) in the bladder with intermediate (1.7-fold) and chronic (2.6-fold) cystitis. COX-2-immunoreactive cell profiles were distributed throughout the inflamed bladder and coexpressed histamine immunoreactivity. Conscious cystometry in rats treated with CYP + DFU showed increased micturition intervals 4 and 48 h after CYP treatment and decreased intravesical pressures during filling and micturition compared with rats treated with CYP + vehicle. These studies suggest an involvement of urinary bladder COX-2 and its metabolites in altered micturition reflexes with CYP-induced cystitis.

Abstract
This study examined tyrosine kinase receptor (Trk) expression and phosphorylation in lumbosacral dorsal root ganglia (DRG) after acute (8 or 48 hours) or chronic (10 days) cyclophosphamide (CYP)-induced cystitis. Increases in the number of TrkA-immunoreactive (IR) cell profiles were detected in the L1 and L6 DRG (four-fold; P < or = 0.01) and the S1 DRG (1.5-fold; P < or = 0.05) but not in the L2, L4, and L5 DRG with CYP-induced cystitis of acute and chronic duration compared with control rats. The number of TrkB-IR cell profiles increased in the L1 and L2 DRG (L1: 2.6-fold; L2: 1.4-fold; P < or = 0.05) and in the L6 and S1 DRG (L6: 2.2-fold; S1: 1.3-fold; P < or = 0.05) only after acute CYP treatment (8 hours). After CYP treatment, the percentage of bladder afferent cell profiles expressing TrkA-IR (approximately 50%; P < or = 0.05) increased in L1 and L6 DRG. The percentage of bladder afferent cell profiles expressing TrkB-IR (approximately 45%; P < or = 0.05) in L1, L2, L6, and S1 DRG also increased compared with control cell profiles. The increase in TrkA-IR in bladder afferent cells occurred 8 hours after CYP treatment and was maintained in L1 DRG with chronic (10 days) CYP-induced cystitis. However, the increase in bladder afferent cells expressing TrkB-IR only occurred at the most acute time point examined (8 hours). TrkA-IR and TrkB-IR cell profiles also demonstrated phosphorylated Trk-IR with acute and/or chronic CYP-induced cystitis. These results demonstrated that CYP-induced cystitis increases the expression and phosphorylation of Trk receptors in lumbosacral DRG. Expression of neurotrophic factors in the inflamed urinary bladder may contribute to this increased expression, and neurotrophic factor and Trk interactions may play unique roles in decreased urinary tract plasticity with CYP-induced cystitis.

Abstract
OBJECTIVE To evaluate supratrigonal cystectomy and enterocystoplasty in patients with interstitial cystitis. METHODS We reviewed four women with interstitial cystitis with infructuos conservative treatment and performed supratrigonal cystectomy and enterocystoplasty. All the patients fulfilled the NHI criteria with increased voiding frequency by night (mean 7.3 times). In 3 cases urodynamic study was available. We used is the four patients ileon as segment for the enterocystoplasty. RESULTS Mean postoperative follow up was 60 months. In all cases the suprapubic pain disappeared and night voiding frequency reduced (mean 2.2 times). We don't have mayor complications. One patient needs self catheterism 3 years after surgery. CONCLUSION In patients with interstitial cystitis to be operated supratrigonal cystectomy and enterocystoplasty is the most effective method.

Abstract
PURPOSE We assess the efficacy of intravesical administration of oxybutynin chloride in patients with interstitial cystitis. MATERIALS AND METHODS The study included 36 women with a mean age of 45 years with a diagnosis of interstitial cystitis. Patients were treated with gradual intravesical instillation of saline oxybutynin solution (oxybutynin group) or gradual filling of simple saline (control group). Evaluation parameters consisted of symptom problem index, voids per day, volume per void, functional bladder capacity, volume at first sensation, cystometric bladder capacity and cystometric volume at first sensation. RESULTS Statistically significant improvement of all evaluated parameters was found in both groups. When comparing the outcomes statistically significant improvement of parameters favored the oxybutynin group. CONCLUSIONS Bladder training alone produces a satisfactory result by gradually expanding the bladder, and an additional statistically significant improvement is evident with intravesical oxybutynin.

Abstract
Interstitial cystitis (IC) is a syndrome of pelvic and/or perineal pain, urinary urgency, and frequency. It is now agreed that IC is a multifactorial syndrome, not a single condition. A variety of etiologies for IC have been proposed, but none has been definitively proven. Since the etiologies for IC remain unknown, the current treatments are empiric. This article will review the major theories of etiology for IC and discuss the current treatment options with relevance to the proposed etiologies. No single treatment is effective for all IC patients. Therefore, the approach is to try different treatments, alone or in combination, until symptom relief is satisfactory. In some cases, none of the empiric IC treatments are successful. These patients require adjunctive pain management, and a small minority of IC patients resort to surgery if all other options fail.
