Abstract
INTRODUCTION Sacral neuromodulation (SNM) is a treatment approved for use in several conditions including refractory overactive bladder (OAB) and voiding dysfunction. Chronic pelvic pain (CPP) is a debilitating condition for which treatment is often challenging. SNM shows promising effect in patients with refractory CPP. However, there is a lack of clear evidence, especially in long-term outcomes. This systematic review will assess outcomes of SNM for treating CPP. METHODS A systematic search of MEDLINE, Embase, Cochrane Central and clinical trial databases was completed from database inception until January 14, 2022. Studies using original data investigating SNM in an adult population with CPP which recorded pre and posttreatment pain scores were selected. Primary outcome was numerical change in pain score. Secondary outcomes were quality of life assessment and change in medication use and all-time complications of SNM. Risk of bias was assessed using the Newcastle Ottawa Tool for cohort studies. RESULTS Twenty-six of 1026 identified articles were selected evaluating 853 patients with CPP. The implantation rate after test-phase success was 64.3%. Significant improvement of pain scores was reported in 13 studies; three studies reported no significant change. WMD in pain scores on a 10-point scale was -4.64 (95% confidence interval [CI] = -5.32 to -3.95, p < 0.00001) across 20 studies which were quantitatively synthesized: effects were maintained at long-term follow-up. Mean follow-up was 42.5 months (0-59). Quality of life was measured by RAND SF-36 and EQ-5D questionnaires and all studies reported improvement in quality of life. One hundred and eighty-nine complications were reported in 1555 patients (Clavien-Dindo Grade I-IIIb). Risk of bias ranged from low to high risk. Studies were case series and bias stemmed from selection bias and loss to follow-up. CONCLUSION Sacral Neuromodulation is a reasonably effective treatment of Chronic Pelvic Pain and significantly reduces pain and increases patients' quality of life with immediate to long-term effects.

Abstract
There are several patients with urination problems and urethral and pelvic discomfort. Usually, these patients’ symptoms are persistent and ambiguous; therefore, it is difficult to find underlying diseases associated with the patient’s symptoms. In addition, there are various conditions such as overactive bladder, cystitis, and interstitial cystitis/bladder pain syndrome (IC/BPS). Sometimes patients with other chronic disorders such as fibromyalgia, inflammatory bowel syndrome, and vulvodynia show urination problems and pelvic pain. Thus, a patient-centered approach is important to find the cause of chronic urination problems and pelvic pain. Moreover, IC/BPS should be considered during the diagnostic process because the clinical characteristics of IC/BPS are diverse. In this narrative review, we suggest an integral approach for the diagnosis and treatment of IC/ BPS.

Abstract
INTRODUCTION Chronic pelvic pain (CPP) is a symptom that derives from a complex group of heterogeneous pathologies of the pelvic organs. The aim of this study was to review the available evidence on efficacy of neuromodulatory modalities including sacral neuromodulation, dorsal root ganglion stimulation, dorsal column neuromodulation, and pudendal nerve stimulation. METHODS This narrative review focuses on updated information on neuromodulation for management of chronic pelvic pain. In 2022, we searched English-language studies on neuromodulation, pelvic pain, and chronic pain in a comprehensive search. We searched the following databases: PubMed, Medline, SciHub, Cochrane Database of Systematic Reviews, and Google Scholar. We used the following combinations of keywords: neuromodulation, pelvic pain, chronic pain, chronic pelvic pain, pelvic pain treatment. We tried to include as many recent manuscripts as possible (within the last 3 years) but also included papers older than 3 years if they were particularly relevant to our topic. We also attempted to search for, use, and cite primary manuscripts whenever possible. RESULTS CPP is a challenging entity to treat because of diagnostic inconsistencies and limited evidence for therapeutic modalities. Our review found evidence suggestive of benefit for all modalities reviewed but the data was of overall low quality with numerous limitations. The literature highlights a lack of randomized controlled trials for neuromodulatory therapies but suggests a growing role for such techniques in treating refractory chronic pelvic pain syndrome (CPPS). CONCLUSIONS This review explores the available evidence on efficacy of neuromodulatory modalities for CPPS and contextualizes the results with information about the type of neuromodulation, lead location and waveform, pain outcomes and assessment timepoints, and reported adverse effects.

Abstract
Neuromodulation is recommended by major international guidelines as a fourth-line treatment in bladder pain syndrome/interstitial cystitis (BPS/IC) patients after failure of behavioural, oral and intravesical pharmacological treatments, including hydrodistension. A non-systematic review of studies identified by electronic search of MEDLINE was performed with no time limitation. A narrative synthesis of the existing evidence regarding the results of sacral, tibial and pudendal nerve stimulation in the management of BPS/IC was developed. Neuromodulation in pelvic chronic pain disorders, including BPS/IC, is a useful tool for refractory patients to conventional treatments. Sacral neuromodulation may be effective in patients with BPS without Hunner's lesions, and the effect seems to be maintained in the mid- and long-term. Posterior tibial nerve stimulation can be offered to patients with BPS/IC in the context of a multidisciplinary approach. When pudendal neuralgia is suspected, selective pudendal nerve stimulation has a high response rate. The aetiology of the pain can influence the outcomes in the mid- and long-term of the different neuromodulation approaches, thus careful diagnosis is recommended.

Abstract
The pelvic splanchnic nerves are essential for pelvic organ function and have been proposed as targets for neuromodulation. We have focused on the rodent homologue of these nerves, the pelvic nerves. Our goal was to define within the pelvic nerve the projections of organ-specific sensory axons labelled by microinjection of neural tracer (cholera toxin, subunit B) into the bladder, urethra or rectum. We also examined the location of peptidergic sensory axons within the pelvic nerves to determine whether they aggregated separately from sacral preganglionic and paravertebral sympathetic postganglionic axons travelling in the same nerve. To address these aims, microscopy was performed on the major pelvic ganglion (MPG) with attached pelvic nerves, microdissected from young adult male Sprague-Dawley rats (6-8 weeks old) and processed as whole mounts for fluorescence immunohistochemistry. The pelvic nerves were typically composed of five discrete fascicles. Each fascicle contained peptidergic sensory, cholinergic preganglionic and noradrenergic postganglionic axons. Sensory axons innervating the lower urinary tract (LUT) consistently projected in specific fascicles within the pelvic nerves, whereas sensory axons innervating the rectum projected in a complementary group of fascicles. These discrete aggregations of organ-specific sensory projections could be followed along the full length of the pelvic nerves. From the junction of the pelvic nerve with the MPG, sensory axons immunoreactive for calcitonin gene-related peptide (CGRP) showed several distinct patterns of projection: some projected directly to the cavernous nerve, others projected directly across the surface of the MPG to the accessory nerves and a third class entered the MPG, encircling specific cholinergic neurons projecting to the LUT. A subpopulation of preganglionic inputs to noradrenergic MPG neurons also showed CGRP immunoreactivity. Together, these studies reveal new molecular and structural features of the pelvic nerves and suggest functional targets of sensory nerves in the MPG. These anatomical data will facilitate the design of experimental bioengineering strategies to specifically modulate each axon class.

Abstract
INTRODUCTION AND HYPOTHESIS Sacral neuromodulation (SNM) is gaining popularity as a treatment option for chronic pelvic pain (CPP). Our hypothesis is that SNM is effective in improving CPP. METHODS A systematic search was conducted through September 2018. Peer-reviewed studies using pre- and postpain intensity scores were selected. The primary outcome was pain improvement on a 10-point visual analog scale (VAS) (adjusted or de novo) in patients with CPP. Secondary outcomes included comparing SNM approaches and etiologies and evaluating lower urinary tract symptoms (LUTS). RESULTS Fourteen of 2175 studies, evaluating 210 patients, were eligible for further analysis. The overall VAS pain score improvement was significant [weighted mean difference (WMD) -4.34, 95% confidence interval (CI) = -5.22, to-3.64, p < 0.0001)]. Regarding SNM approach, both standard and caudal approaches had significant reduction in pain scores: WMD -4.32, CI 95% = -5.32, to -3.31 (p < 0.001) for the standard approach, compared with WMD -4.63, 95% CI = -6.57 to -2.69 (P < 0.001), for the caudal approach (p = 0.75). While significant improvement in pain was observed both in patients with and without interstitial cystitis/bladder pain syndrome (IC/BPS), the observed improvement was lower in patients with (WMD -4.13, CI 95% -5.36 to -2.90 versus without (WMD -5.72, CI 95% = -6.18, to-5.27) IC/BPS (p = 0.02). SNM was effective in treating voiding symptoms (frequency, urgency, nocturia) associated with IC/BPS (all p < 0.01). CONCLUSIONS SNM is an effective therapy for CPP in both IC/BSP and non-IC/BSP patients, with better results in non-IC/BSP patients. Outcomes of the antegrade caudal approach were comparable with the standard retrograde approach.

Abstract
Bladder pain syndrome/interstitial cystitis (BPS/IC) is a common debilitating disease and there has not been consistently effective treatment. We aimed to evaluate all available literature regarding the efficacy and safety of sacral neuromodulation (SNM) for refractory BPS/IC. A comprehensive search of Pubmed, Web of Science and Cochrane Library through May 2016 was conducted. A total of 17 studies enrolling 583 patients were identified. Pooled analyses demonstrated that SNM was associated with great reduction in pelvic pain (weighted mean difference [WMD] −3.99; 95% confidence interval [CI] −5.22 to −2.76; p < 0.00001), Interstitial Cystitis Problem and Symptom Index scores (WMD −6.34; 95% CI −9.57 to −3.10; p = 0.0001; and WMD −7.17; 95% CI −9.90 to −4.45; p < 0.00001, respectively), daytime frequency (WMD −7.45; 95% CI −9.68 to −5.22; p < 0.00001), nocturia (WMD −3.01; 95% CI −3.56 to −2.45; p < 0.00001), voids per 24 hours (WMD −9.32; 95% CI −10.90 to −7.74; p < 0.00001) and urgency (WMD −1.08; 95% CI −1.79 to −0.37; p = 0.003) as well as significant improvement in average voided volume (WMD 95.16 ml; 95% CI 63.64 to 126.69; p < 0.0001). The pooled treatment success rate was 84% (95% CI 76% to 91%). SNM-related adverse events were minimal. Current evidence indicates that SNM might be effective and safe for treating refractory BPS/IC.

Abstract
Interstitial cystitis (IC)/painful bladder syndrome/bladder pain syndrome (BPS) is a chronic hypersensory condition of unknown etiology. Moreover, the optimal modality for diagnosing IC remains disputed. Several urinary markers have been investigated that may have potential utility in the diagnosis or confirmation of IC/BPS. Thus, inflammatory mediators, proteoglycans, urinary hexosamines, proliferative factors, nitric oxide (NO), BK polyomavirus family, and urothelial proinflammatory gene analysis have been found to correlate with varying degrees with the clinical diagnosis or cystoscopic findings in patients with IC/BPS. The most promising urinary biomarker for IC/BPS is antiproliferative factor, a sialoglycopeptide that has demonstrated inhibitory effects on urothelial cell proliferation and a high sensitivity and specificity for IC/BPS symptoms and clinical findings. In this article, we review the urinary markers, possible future therapies for IC/BPS, and the clinical relevance and controversies regarding the diagnosis of IC/BPS.

Abstract
Sacral nerve stimulation is a young but promising technique in the treatment of chronic voiding dysfunctions. Electrical stimulation of the S3 nerve--using a pacemaker device--is able to treat a wide range of pelvic floor dysfunctions. This article gives a brief review on the indications, mechanisms of action and possible complications of this technique. Furthermore, new evolutions in the domain of sacral nerve modulation are discussed.

Abstract
PURPOSE Chronic pelvic pain syndrome is a debilitating disease which often has a major impact on quality of life. A significant number of patients do not respond to conservative treatment and often no good alternative can be offered except radical surgery. Sacral neuromodulation is a well established therapy for patients with lower urinary tract dysfunction. This therapy has also been suggested to be useful in the treatment of chronic pelvic pain. Although currently no Food and Drug Administration approval exists for this indication, several studies have demonstrated promising results. We provide an overview of the published literature on sacral neuromodulation as a treatment for chronic pelvic pain. MATERIALS AND METHODS A PubMed® search was performed to identify articles in English from 1990 to February 2010 reporting treatment of pelvic pain with sacral neuromodulation. In addition, the current definitions of pelvic pain syndromes and the mechanisms of action are discussed. RESULTS A total of 12 relevant articles were identified. Of these articles 10 mainly addressed the efficacy of sacral neuromodulation in patients with interstitial cystitis/bladder pain. The percentage of patients who responded to test stimulation was reported between 51% and 77%. Of the 10 articles 7 reported treatment outcome after implantation. The duration of followup ranged between 5 and 87 months. The mean reduction in pain scores was reported between 40% and 72%. The reoperation rate ranged between 27% and 50% after long-term followup. Two articles included patients with miscellaneous urogenital pain syndromes. The success rates after implantation ranged from 60% to 77% with followup ranging between 19 and 36 months. CONCLUSIONS Currently there is insufficient evidence to determine the role of sacral neuromodulation in the treatment of chronic pelvic pain. Larger prospective trials with long-term evaluation are required to determine the ultimate efficacy of this treatment.

Abstract
AIMS This study was sought to evaluate the efficacy and durability of sacral neuromodulation in the treatment of bladder pain syndrome (BPS) patients. METHODS A retrospective chart review was performed of patients who had unilateral sacral nerve stimulator (InterStim®) for refractory BPS between June 2002 and December 2004. Patients were qualified for permanent implantation by showing ≥ 50% improvement in their bladder pain and voiding symptoms 1-week post-percutaneous nerve evaluation (PNE). Voiding diary was completed at pre-implantation, 1 year, and on the last visit. Urinary distress inventory short form was completed pre-implantation and on the last visit. Bladder pain was evaluated by visual analogue scale. Primary outcome was improvement in bladder pain. Differences among groups were compared by one-way ANOVA and t-test. Statistical significance was set at P ≤ 0.05. RESULTS Twenty-one female patients diagnosed with BPS had PNE; 11 patients (52%) showed ≥ 50% improvement in their bladder pain and voiding symptoms and they consider candidates for permanent implantation (Table I), while 10 patients (48%) failed to show 50% improvement in their voiding symptoms or bladder pain (Table II). In those 11 patients who underwent permanent implantation, the average patient's age was 44.3 ± 8.9 years; average time since diagnosis was 3 ± 0.8 years; the average follow- up was 71.5 ± 9.3 months (Table III). There was significant improvement in the bladder pain and voiding parameters at 1-year follow-up, which was maintained at 5-year follow-up. There was continuous improvement in urgency (1.2 ± 0.68) at 1-year follow-up, and (0.98 ± 0.72) at the last visit. Average voided volume was also continuously improved from 242 ± 62.7 ml at 1-year follow-up to 276 ± 64.7 ml on the last visit. CONCLUSION Sacral neuromodulation as part of multimodal treatment provides an effective long-term treatment option for sub-group of refractory BPS.

Abstract
Sacral neuromodulation has been developed to treat chronic lower urinary tract symptoms, resistant to classical conservative therapy. The suspected mechanisms of action include afferent stimulation of the central nervous system and modulation of activity at the level of the brain. Typical neuromodulation is indicated both in overactivity and in underactivity of the lower urinary tract. In the majority of patients, a unilateral electrode in a sacral foramen and connected to a pulse generator is sufficient to achieve significant clinical results also on long term. In recent years, other urological indications have been explored.

Abstract
The lower urinary tract dysfunction encompasses voiding, postvoiding, and storage symptoms. Conventional treatment modalities include pharmacotherapy and behavioural therapy. Sacral neuromodulation (SNM) is a safe and minimally invasive treatment modality that has recently gained wide acceptance in the management of urinary urge incontinence, urge frequency, and nonobstructive urinary retention, in particular, among those patients with conditions refractory to conventional methods. We searched multiple electronic databases through June 30, 2009 for eligible studies. We examined published clinical and experimental studies concerning the mechanisms of action of SNM. In the first part of the manuscript, we describe the anatomy and functions of the lower urinary tract including the reflexes involved in its functions and then review the pathophysiology of major types of the lower urinary tract dysfunction. In the second part, we discuss different ways for SNM to control various types of voiding dysfunction. The lower urinary tract dysfunctions affect millions of people worldwide and have a severe impact on their quality of life. SNM offers a safe and minimally invasive modality in the treatment of voiding dysfunctions, especially in patients with conditions refractory to conventional therapies.

Abstract
Reliable diagnostic markers for Bladder Pain Syndrome/Interstitial Cystitis (IC) currently are not available. This study evaluated the feasibility of diagnosing IC in humans and domestic cats from the spectra of dried serum films (DSFs) using infrared microspectroscopy. Spectra were obtained from films from 29 humans and 34 domestic cats to create classification models using Soft Independent Modeling by Class Analogy (SIMCA). Ultrafiltration of serum improved discrimination capability. The classification models for both species successfully classified spectra based on condition (healthy/sick), and a different set of masked spectra correctly predicted the condition of 100% of the subjects. Classification required information from the 1500-1800 cm(-1) spectral region to discriminate between subjects with IC, other disorders, and healthy subjects. Analysis of cat samples using liquid chromatography-mass spectroscopy revealed differences in the concentration of tryptophan and its metabolites between healthy and affected cats. These results demonstrate the potential utility of infrared microspectroscopy to diagnose IC in both humans and cats.

Abstract
OBJECTIVES To investigate whether the urine of interstitial cystitis (IC) patients has a toxic effect on the bladder wall, as determined by mast cell infiltration, and to evaluate the preventive effect of tibial nerve electric stimulation (TNES) on bladder mastocytosis induced by IC urine. MATERIAL AND METHODS The bladders of female rats were catheterized and instilled with IC urine (Group IC; n=10) and normal urine (Group NU; n=5) obtained from humans, saline (Group S; n=5) and protamine sulphate (Group PS; n=10) for 6 weeks. Additionally, in five rats instilled with IC urine and five instilled with PS, TNES was also performed (Groups IC + TNES and PS + TNES). RESULTS In the lamina propria of the bladder, the mean number of mast cells per square millimetre was significantly higher in Groups IC (32.5+/-12.3) and PS (39.4+/-11.1) than in Groups S (11.9+/-4.3) and NU (13.7+/-3.5). After TNES, the corresponding values were decreased significantly to 15.3+/-5.4 and 15.3+/-4.1 in Groups IC + TNES and PS + TNES, respectively (p<0.001). A significant reduction in mast cell infiltration in the detrusor was also determined after TNES compared with the value in Group IC (4.6+/-1.6 vs 12.1+/-3.0; p<0.001). CONCLUSIONS We demonstrated that IC urine may result in increased mast cell infiltration in the bladder wall. TNES may play a therapeutic role by diminishing the mast cell count in the bladder wall, which has a strong relationship with nociceptive neural endings.

Abstract
Voiding dysfunction, which includes incontinence, retention, and chronic pelvic pain, is a relatively frequent problem that can be difficult to manage. Neuromodulation via stimulation of the sacral nerves has been shown to improve these symptoms, although the exact mechanisms remain elusive. Techniques for nerve stimulation may vary, depending on the disease, location of pain, and the patient's anatomy. In addition to placement of electrodes on the sacral nerve roots, modulation has also been reported by peripheral branches of the sacral nerves including the pudendal and posterior tibial nerves. Newer surgical techniques have significantly decreased the morbidity of the procedures and increased the probability of a successful outcome.

Abstract
OBJECTIVE To compare sacral nerve stimulation (SNS) with pudendal nerve stimulation (PNS) for interstitial cystitis (IC). PATIENTS AND METHODS Twenty-two patients with well-documented, refractory IC had a tined lead placed at S3 and a second electrode implanted at the pudendal nerve via a posterior approach. In a blinded, randomized design, each lead was tested for 7 days. The best lead was implanted to a pulse generator and patients were followed at 1, 3 and 6 months. RESULTS The time required to place a sacral lead was 27.4 min, and a pudendal lead 19.6 min (P = 0.039). Of the 22 patients, 17 (77%) responded and had a permanent implant placed. PNS was chosen as the better lead in 77% and SNS in 24%. The order in which the lead was stimulated had no effect on the final lead implanted and there was no 'carry-over' effect. The overall reduction in symptoms was 59% for PNS and 44% for SNS (P = 0.05). At 6 months after implantation, voids improved by 41% (PNS) and 33% (SNS), and mean voided volume increased 95% and 21%, respectively; validated IC questionnaires improved markedly and complications were minimal. CONCLUSIONS This is the first 'blinded' study of SNS vs PNS for IC. A pudendal lead was implanted successfully in all patients, and most chose PNS as better than SNS; the improvement was sustained over time.

Abstract
We measured candidate urine biomarkers and bladder cell DNA cytometry in interstitial cystitis (IC) patients randomized to receive intravesical Bacillus Calmette Guerin (BCG) or placebo in a multicenter trial. Participants received 6 weekly instillations and were followed for 34 weeks. Urine was collected at baseline, prior to fourth treatment, and at study end. Antiproliferative factor (APF) activity was determined by 3H-thymidine incorporation assay; heparin-binding epidermal growth factor-like growth factor (HB-EGF) and epidermal growth factor-like growth factor (EGF) levels were determined by ELISA. Cellular DNA content was measured by image analysis to determine the mean hyperdiploid fraction (HDF) of the urine cell pellet. Associations between marker levels, and treatment or symptoms, were examined. Baseline APF positivity rate and mean levels of the other biomarkers were similar to previous smaller studies. During the week 34 follow-up, mean HDF decreased (P = 0.0003) and HB-EGF increased (P < 0.0001); both correlated weakly with decreased urgency. There was no difference in any biomarker between symptom responders and non-responders, but the percentage of responders was low and not significantly different for BCG versus placebo. APF positivity, decreased HB-EGF, increased EGF, and increased HDF were confirmed at baseline in IC patients. Changes in HDF and HB-EGF levels correlated weakly with changes in urgency, but the low BCG response rate prevented identification of additional associations between biomarker changes and treatment or symptoms.

Abstract
Patients with symptoms of overactive bladder syndrome or non-obstructive urinary retention, refractory to conservative therapy, can nowadays be treated minimally invasively with sacral nerve stimulation (SNS). The use of electric currents to treat urological pathology has a long history but SNS therapy only received FDA approval in 1997. The mechanisms of action are still not known so there are different theories explaining the modulation effect. Recent studies have shown a central modulation effect. Predictive factors which can help to identify the perfect candidates are not known. Over the years the technique of SNS has become less invasive and because of two stage implantation test results have proven to be more reliable. The clinical results for this therapy have proven to be safe and effective and with the technical improvements over the years the re-operation and complication rates have decreased significantly. The clinical results have led to expanding indications because of positive effects in other symptoms. In the field of urology this has resulted in the use of SNS therapy for interstitial cystitis, neurogenic lower urinary dysfunction, and pediatric voiding dysfunction. In the field of gastro-intestinal pathology, SNS therapy is used to treat faecal incontinence and constipation.

Abstract
This update reviews the published literature from the past 2 years pertaining to urinary and serum markers for interstitial cystitis (IC). Literature on markers described before 2004 also is included when needed to provide background information for the current literature. The markers that have been the focus of the most research in the recent literature are antiproliferative factor, epidermal growth factor, heparin-binding epidermal growth factor-like growth factor, glycosaminoglycans, and bladder nitric oxide. These markers are discussed in consideration of their three different possible roles: 1) as diagnostic markers of IC; 2) distinguishing relevant subsets of IC patients; and 3) measuring disease activity and objectively following treatment response.

Abstract
For years the bladder epithelium has been the focus for diagnosing and treating the frequency, urgency, and pelvic pain of interstitial cystitis. However, many patients have not found symptom relief with these therapies. Pelvic floor dysfunction is often present in these patients, yet it is often untreated. Pelvic floor dysfunction may be related to abuse, past surgeries, or other causes. It is important to look outside of the bladder and explore other causes and treatments for this condition. Pelvic floor therapies should be a first line of treatment for those women with chronic pelvic pain related to pelvic floor dysfunction.

Abstract
Interstitial cystitis is an enigmatic and frustrating condition to manage as a physician and to cope with as a patient. Traditionally, it has been defined as a chronic sterile inflammatory disease of the bladder of unknown aetiology. However, the International Continence Society prefers the term painful bladder syndrome and it has been decided to follow this terminology and refer to the disease as painful bladder syndrome/interstitial cystitis (PBS/IC). The condition is characterized by bladder pain, urinary frequency, urgency and nocturia. The quality of life of patients with PBS/IC is significantly degraded. Its aetiology is unknown, but might involve microbiologic, immunologic, mucosal, neurogenic and other yet unidentified agents. History, physical examination, urine analysis and culture as well as cystoscopy and hydrodistension are useful diagnostic tools but the final diagnosis tends to be a diagnosis of exclusion. This article will review the major theories of aetiology for PBS/IC and discuss diagnosis as well as the current treatment options with relevance to the proposed aetiologies.

Abstract
Interstitial cystitis (IC) is a chronic symptom-complex characterized by pathological sensation of the bladder (i.e. bladder pain in addition to augmented sensory signals such as urinary frequency and urgency) without evidence of bacterial cystitis or other identifiable lower urinary tract disease. Patients with IC typically describe feeling the urge to void frequently, as well as pain in the bladder and/or urethra. The painful sensation may be described as burning, pressure, sharp, or aching, and is often difficult for the patient to localize precisely. Multiple theories as to the cause of IC have been proposed with varying degrees of evidence. The current body of literature supports the idea that IC is associated with an intrinsic pathology of the bladder urothelial cells. The identification and complete characterization of antiproliferative factor (APF), which is uniquely expressed by urothelial cells in bladders affected by IC, are major advances in the understanding of IC. Additionally, urothelial cells have been likened to neurons because of their ability to express neuronal receptors and release neurotransmitters. The purinergic pathway has been shown to be upregulated in urothelial cells in bladders affected by IC. These new findings should help to direct the development of newer clinical treatments for IC. A complete understanding of IC will only be possible with parallel advances in both basic and clinical sciences.

Abstract
The dilemma of managing patients with chronic pelvic pain syndromes continues to frustrate physicians confronted with these complaints. Multiple diagnoses traditionally label this condition in men and women and, typically, implicate a pelvic-organ system when, in fact, very little objective evidence for a pathophysiologic process exists. Traditional therapies, consisting of antibiotics, anti-inflammatories, and muscle relaxants, simply do not work, and their lack of efficacy compared with placebo has been documented by randomized clinical trials in the US that were sponsored by the NIH. What do we do now? This review article attempts to describe the clinical efforts of several investigators and to put their patients' outcomes in perspective, and thereby suggest alternative therapies to help these patients.

Abstract
Painful bladder syndrome/interstitial cystitis is a disabling disease of the urinary bladder that mainly affects women. It is of unknown etiology and can appear in all age groups. The main symptoms - bladder pain and urinary frequency - may completely govern the life of the unlucky person suffering from the disease. Treatment includes diet, behavioral modifications, medical treatments, inclusive specific-pain treatment and surgery, but it is unfortunately often insufficient. The disease is rare and lacks a specific definition as well as proper diagnostic criteria. Surgical treatments include neuromodulation, transurethral surgery, bladder augmentation and urinary diversion with or without cystectomy. This article examines the documentation, or lack of, for the often drastic surgical procedures performed to improve quality of life in patients with this disorder.

Abstract
OBJECTIVE Sacral root neuromodulation is an effective technique for the treatment of Chronic Micturition Dysfunction (CMD) refractory to conventional therapy. New indications such as chronic pelvic pain and interstitial cystitis are currently making their way within the urologic setting. Several groups of gastric surgeons are now choosing this technique for the management of rectal diseases (constipation, sphincter dysfunction). This paper contributes our experience in the treatment of patients with CMD and the comparative results at one year from implant in all patients. MATERIAL AND METHODS From December 1998 through July 2003, 18 neuromodulation definite implants were performed. The main indication was CMD in 62.5% patients. Follow up of patients was done at one month and three months, and every six months thereafter. Follow up is conducted through a micturition diary and QoL questionnaire. Electrode implant in the first 16 patients was achieved by open surgery. The next 2 patients had the electrode placed by a percutaneous technique using the "Tined Lead" kit. RESULTS Results at one year after implant were compared in all patients. The total number of neuromodulation implants placed was 18, 14 (77.7%) of which were women and 4 (22.3%) men. Mean age was 52.56 years. Implant indication was CMD in 72.2% patients, mixed incontinence (urinary and faecal) in 22.1%, and interstitial cystic disease in 5.5%. Symptoms improvement at one year from implant, as determined by a micturition diary and QoL questionnaire was 76.4%. Clinical improvement was greater in patients with urgency symptoms than in patients with predominance of voiding symptoms.

Abstract
Neuromodulation in one form or another has been studied for decades for various disease states. Although its mechanism of action remains un-explained, numerous clinical success stories suggest it is a therapy with efficacy and durability. Controlled studies have led to the approval of sacral neuromodulation for urinary urgency and frequency, urinary retention, and urinary urge incontinence. The future holds hopeful possibilities for the application of neuromodulation, namely in the areas of interstitial cystitis, in-tractable pain syndromes, fecal incontinence and constipation, spinal cord injury, and erectile dysfunction. Neuromodulators have also been used in nonurologic conditions, including chronic headaches and intractable chest pain. In adults and children, in the neurologically intact and neurologically impaired, neuromodulation has been shown to improve the quality of life of those suffering chronic disease states. Neuromodulation is changing the future of urology. Treatment of voiding dysfunction and likely other disorders, such as pelvic pain, sexual dysfunction, and bowel disorders, will no longer rely only on medications that are "OK" or destructive-reconstructive procedures that suffer from significant complications. Rather, by modulating the nerves, the urologists will treat these disorders in a minimally invasive fashion and neuromodulation will become the first-line therapy before any major surgery is undertaken.

Abstract
OBJECTIVE To evaluate the efficacy of intermittent percutaneous posterior tibial nerve stimulation (PPTNS) in patients with refractory interstitial cystitis. PATIENTS AND METHODS One man and 13 women (mean age 58.3 years) with suprapubic or perineal pain were enrolled in a prospective open study, in which they had 10 weekly sessions of PPTNS. Their mean duration of symptoms was 8.3 years. All patients were previously diagnosed as having interstitial cystitis according to the National Institute of Diabetes and Digestive and Kidney Diseases criteria. The response to the treatment were assessed using voiding diary, visual analogue scale diary for a pain index, and the Interstitial Cystitis Problem Index (ICPI), O'Leary/Sant Interstitial Cystitis Symptom Index (ICSI) and the 36-item short-form health survey (SF-36) quality-of-life questionnaire. RESULTS Of the 14 patients, 13 completed the 10 weeks of treatment with no complications; 12 continued treatment for a short period after the study. There were no statistically significant changes in pain scores, voiding frequency and volumes, or in the ICPI, ICSI and SF-36 scores. However, there was an improvement in some patients, with one having complete resolution of the pain. CONCLUSION Intermittent PPTNS in patients with refractory interstitial cystitis has no significant clinical effect over 10 weeks of treatment.

Abstract
OBJECTIVES To determine whether men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) have urine markers previously described for patients with interstitial cystitis (IC; presence of antiproliferative factor [APF] activity, decreased levels of heparin-binding epidermal growth factor-like growth factor [HB-EGF], and increased levels of epidermal growth factor). METHODS Clean catch urine specimens were collected from 41 symptomatic patients with CP/CPPS, 36 asymptomatic men without bladder disease who served as the control group, and 24 men with IC. APF activity was determined by (3)H-thymidine incorporation into primary normal adult human bladder epithelial cells. HB-EGF and epidermal growth factor levels were determined by enzyme-linked immunosorbent assay. RESULTS Men with CP/CPPS did not differ significantly from asymptomatic controls for any of the three markers tested (P >0.49). In contrast, APF activity was present significantly more often and HB-EGF levels were significantly lower in the urine specimens from men with IC than in the specimens from controls or patients with CP/CPPS (P <0.00001 for all four comparisons). Although the epidermal growth factor levels also tended to be higher in the urine from patients with IC than in the urine from controls, the difference did not reach statistical significance (P = 0.06). CONCLUSIONS These findings indicate that at least two of the urine biomarkers previously identified in women with IC (presence of APF activity and decreased levels of HB-EGF) are also found in men with IC, but not in men with CP/CPPS. This finding suggests that IC and CP/CPPS may be two different disorders with distinct pathophysiologies. It also confirms the utility of the presence of APF activity and HB-EGF levels as markers for IC in men, as well as in women, with this disorder.

Abstract
Background Interstitial cystitis (IC) is a chronic bladder disorder of unknown etiology. Antiproliferative factor (APF), a peptide found in the urine of IC patients, has previously been shown to decrease incorporation of thymidine by normal bladder epithelial cells. This study was performed to determine the effect of APF on the cell cycle of bladder epithelial cells so as to better understand its antiproliferative activity. Methods Explant cultures from normal bladder biopsy specimens were exposed to APF or mock control. DNA cytometry was performed using an automated image analysis system. Cell cycle phase fractions were calculated from the DNA frequency distributions and compared by two-way analysis of variance (ANOVA). Results APF exposure produced statistically significant increases in the proportion of tetraploid and hypertetraploid cells compared to mock control preparations, suggesting a G2 and/or M phase cell cycle block and the production of polyploidy. Conclusions APF has a specific effect on cell cycle distributions. The presence of a peptide with this activity may contribute to the pathogenesis of interstitial cystitis through disruption of normal urothelial proliferation and repair processes.

Abstract
OBJECTIVE To assess the efficacy of long-term sacral neuromodulation (InterStim(R), Medtronic Inc., Minneapolis, MN) in treating chronic pelvic pain associated with interstitial cystitis (IC, a symptom complex of urinary urgency, frequency and pelvic pain, often necessitating narcotics) refractory to standard therapy. PATIENTS AND METHODS Twenty-one patients (17 female, four male, mean age 45.5 years, range 17-68) with refractory IC with chronic pelvic pain were reviewed retrospectively. In these patients a mean of six previous treatments for IC had failed. All patients had had cystoscopy and hydrodistension to confirm their diagnoses. All had a permanent InterStim device implanted by one surgeon (K.M.P.) between 2000 and 2002, after responding to a temporary test. Data were collected from chart reviews and patient questionnaires. Intramuscular morphine dose equivalents (MDEs) were calculated before and after implantation. RESULTS All 21 patients responded to the questionnaire; the mean (range) follow-up after implantation was 15.4 (7.4-23.1) months. Eighteen patients used chronic narcotics before the InterStim and 20 reported moderate or marked improvement in pain afterward. The mean MDE decreased from 81.6 to 52.0 mg/day (36%) after implantation (P = 0.015). Four of 18 patients stopped all narcotics after InterStim implantation. CONCLUSIONS Sacral neuromodulation decreases narcotic requirements and subjective pelvic pain in patients with refractory IC. Further decreases in MDE are anticipated as dose reductions continue in patients who improved.
