To present single institution open-label experience with intravesical liposomes ( LPs ) , a mucosal protective agent , in patients with interstitial cystitis/painful bladder syndrome ( IC/PBS ) and to assess the safety and efficacy on IC/PBS symptoms . A total of 17 symptomatic IC/PBS patients were treated with intravesical LPs ( 80mg/40mL distilled water ) once a week for 4 weeks ( n=12 ) or twice a week treatment for 4 weeks ( n=5 ) . The primary outcome was the change in the O'Leary-Sant Symptom/Problem score and O'Leary-Sant total Score from baseline to Week 4 and Week 8 . Other outcome measurements included the changes in pain scale , urgency scale , voiding log , and patient global assessment . Both weekly and biweekly LP instillation regiments were well tolerated . The incidence of urinary incontinence , retention , or unanticipated adverse changes was not noted at any dose either during the treatment or at the 4-week follow-up . The O'Leary-Sant Symptom/Problem score , O'Leary-Sant total Score , and pain score were significantly improved from baseline at both dose regimens with added benefit with the biweekly regimen . Intravesical LPs treatment is safe and its efficacy has sustained duration . Furthermore large-scale , placebo-controlled studies are warranted to assess the efficacy for this promising new treatment for IC/PBS Introduction and hypothesisIntravesical instillation of hyaluronic acid ( HA ) may restore the integrity of glycosaminoglycan layer in patients with painful bladder syndrome/interstitial cystitis ( PBS/IC ) , and the benefit may be improved with addition of alkalinized lidocaine ( AL ) . Methods 48 women with severe PBS/IC who failed oral medications were enrolled and divided into one trial and two control groups . The trial group received intravesical 40 mg HA , 10 ml of 2 % lidocaine and 5 ml of 8.4 % sodium bicarbonate on a weekly basis for 8 weeks and then monthly for 4 months with a subsequent follow-up of 24 weeks , while the two control groups received 40 mg HA and mixture of 10 ml of 2 % lidocaine and 5 ml of 8.4%sodium bicarbonate respectively following the same procedure . Response to therapy was evaluated by Global Response Assessment , voids per day , Visual Analogue Scale for pain , frequency and urgency , O’leary-Sant Interstitial Cystitis Symptom Index and Problem Index , cystoscopy and bladder capacity . Results Overall 45 patients finished this study protocol . The HA + AL group and the AL group showed significant improvement at week 2 ( P < 0.01 ) , while the HA group began to show effect at week 4 ( P < 0.01 ) . There was no improvement in the AL group at week 24 and these patients quitted the study without follow up . Contrarily , the HA + AL and HA group kept on improving till the end of the study without significant difference between the two groups . Conclusions Intravesical instillation of HA and AL may provide both immediate and sustained relief of symptoms in severe PBS/IC in this preliminary study OBJECTIVE The goal of this pilot study was to gather information on differences between intravesical chondroitin sulfate and inactive vehicle control for treatment of interstitial cystitis/painful bladder syndrome ( IC/PBS ) . METHODS This was a prospect i ve , r and omized , double-blind , inactive vehicle-controlled , 12-week study ( 6-week treatment period , followed by a 6-week follow-up period ) in patients with IC/PBS . Patients were r and omized to weekly intravesical treatment with 2.0 % sodium chondroitin sulfate in phosphate-buffered saline or intravesical vehicle control . Primary efficacy analysis compared responders ( moderately or markedly improved ) according to the 7-point Global Response Assessment . Secondary endpoints include question naires focused on symptoms and quality of life . RESULTS Sixty-five evaluable patients were r and omized . At the primary endpoint analysis ( week 7 ) , 22.6 % of the vehicle control group were responders compared with 39.4 % of the active therapy group ( P = .15 ) . There was no statistically significant difference for any of the secondary endpoints . Overall , 76.9 % of the patients in the study reported at least 1 adverse event ; most were mild or moderate , the majority associated with the vehicle control treatment . Nine nonserious intervention-related adverse events were reported in 3 patients in the vehicle control group compared with 2 in 1 patient in the active treatment group . CONCLUSION The difference in treatment effect in this small underpowered study was not statistically significant , although twice as many patients reported a clinical ly significant benefit with intravesical chondroitin sulfate treatment compared with vehicle control treatment . This trial provides data required to design a well-powered r and omized vehicle-controlled trial to determine the true efficacy of this potentially promising therapy PURPOSE We evaluated the effectiveness of combining behavioral therapy , pharmacologic therapy and endoscopic hydrodistension for treating  painful bladder syndrome / interstitial cystitis ( PBS/IC ) .  MATERIAL S AND METHODS Twenty-five patients with PBS/IC were prospect ively enrolled in a pilot multimodal behavioral , pharmacologic and endoscopic treatment protocol . Behavioral modification included diet recommendations , fluid restriction to 64 oz . /day , progressive timed voiding and Kegel exercises . Oral pharmacologic therapy consisted of daily doses of macrodantin 100 mg , hydroxyzine 10 - 20 mg and urised 4 tablets .  Patients underwent endoscopic bladder hydrodistention under anesthesia  at least 2 weeks after protocol enrollment . Behavioral and pharmacological treatments were continued after the hydrodistention . O'Leary-Sant question naire scores were recorded before starting the protocol , after pharmacologic/behavioral therapy , 2 months post-hydrodistension , and at scheduled follow-up . RESULTS Eighteen patients ( 72 % ) completed the pilot multimodal treatment protocol and were followed for a mean of 10.2 months . All patients were female with a median age of 36.3 years and had mean bladder capacity under anesthesia of 836 milliliters .  Mean O'Leary-Sant symptom index scores for baseline symptoms , after behavioral/pharmacologic treatment , post-hydrodistension and during follow up were 12.5 , 8.6 , 7.0 , and 6.7 ( p < 0.05 ) . Mean O'Leary-Sant problem index scores for baseline , after behavioral/pharmacologic treatment , post-hydrodistention and during follow up were 12.7 , 8.9 , 6.7 , and 7.7 ( p < 0.05 ) . CONCLUSION Our pilot multimodal protocol of behavioral modification , pharmacologic therapy and endoscopic hydrodistention demonstrated a significant progressive improvement in PBS/IC quality of life scores , compared to a pre-treatment baseline . These results should be vali date d in a larger , placebo controlled trial Objective : Painful bladder syndrome/interstitial cystitis ( PBS/IC ) and recurrent urinary tract infections ( UTI ) are clinical ly challenging conditions to manage in patients . We evaluate the clinical use of intravesical sodium hyaluronate ( Cystistat ® ) in both these patient groups who have completed treatment . Patients and Methods : Thirteen patients with recurrent UTIs ( Group I ) and 8 patients with PBS/IC ( Group II ) received intravesical sodium hyaluronate ( Cystistat ® ) . Preinstallation demographic parameters were statically comparable in both groups . The mean age of presentation was 54.6 years in Group I and 57.5 years in Group II ( p = 0.9 ) . All 13 patients in Group I were on low dose antibiotics . The mean number of installations completed in both groups was 9 ( range 4–21 ) . Results : Data was collected prospect ively using a st and ard pre- and post-treatment question er with the pelvic pain and urinary/frequency patient symptom scale . At a mean follow-up of 21 months a significant improvement in bladder pain ( p = 0.05 ) , daytime frequency ( p = 0.03 ) and quality of life ( p = 0.02 ) was noted in patients in Group I. Two patients had breakthrough UTIs during treatment . Within Group I , 7 ( 53 % ) patients responded well to treatment . Patients in Group II had a significant improvement in bladder pain ( p = 0.02 ) , urgency ( p = 0.01 ) , nocturia ( p = 0.01 ) and quality of life ( p = 0.04 ) . Within Group II , 6 patients ( 75 % ) responded to treatment . Conclusion : Intravesical sodium hyaluronate ( Cystistat ® ) can be used with minimal side effects and good compliance in both groups of patients with PBS and recurrent UTIs . Longer follow-up and larger patient numbers in both groups will be required to confirm the long-term efficacy of these two clinical ly challenging groups of patients Objective . To evaluate changes in bladder capacity and potassium sensitivity after glycosaminoglycan ( GAG ) substitution therapy . Material and methods . The study population comprised two groups of female patients with bladder pain syndrome/interstitial cystitis ( BPS/IC ) : responders ( those with symptom improvement ) and non-responders ( those without symptom improvement ) after a 10-week period of intravesical , episodic , weekly , GAG substitution therapy . A total of 27 volunteers with increased pre-therapeutic potassium sensitivity were enrolled in the study and re-evaluated using the modified comparative potassium test ( maximal bladder capacity with a saline solution versus a 0.2 M KCl solution ) following intravesical GAG substitution therapy . Results . In the 13 responders , the average maximal bladder capacity increased by 17 % with the saline solution and by 101.5 % with the 0.2 M KCl solution . In the 14 non-responders , post-therapeutic average maximal bladder capacity was decreased by 35 % with the saline solution and remained relatively unchanged after instillation with a 0.2 M KCl solution . Conclusion . These data demonstrate that in patients who respond symptomatically to intravesical GAG substitution therapy , cystometric bladder capacity is increased , whereas non-responders experience a decrease in bladder capacity The aims of this study were to evaluate the efficacy and tolerability of intravesical instillations of high-molecular-weight hyaluronic acid ( HA ) 1.6 % and chondroitin sulfate ( CS ) 2.0 % in patients with refractory painful bladder syndrome/interstitial cystitis ( PBS/IC ) and to observe their impact on Quality of Life . Twenty-three women were enrolled . They received bladder instillations with HA and CS weekly for 20 weeks and then monthly for 3 months . Mean follow-up after completion of therapy was 5 months . We observed a significant improvement in urinary symptoms on voiding diaries and Visual Analogue Scale for frequency ( p = 0.045 ) , urgency ( p = 0.005 ) , and pain ( p = 0.001 ) . The O’Leary – Sant Interstitial Cystitis Symptom Index and Interstitial Cystitis Problem Index result ed in a significant improvement in both scores ( p = 0.004 and 0.01 , respectively ) . The Pelvic Pain and Urgency/Frequency Symptom Scale only showed significant improvement in the symptom score ( p = 0.001 ) . This promising experience seems to offer an additional therapeutic option in patients with refractory PBS/IC OBJECTIVES To compare the clinical effectiveness of different regimens of intravesical hyaluronic acid instillation for patients with interstitial cystitis/painful bladder syndrome . METHODS A total of 60 patients ( age 16 - 77 years ) diagnosed with interstitial cystitis/painful bladder syndrome were enrolled in this prospect i ve , r and omized study . A total of 30 patients were assigned to receive four weekly intravesical instillations of 40 mg of hyaluronic acid followed by five monthly instillations ( hyaluronic acid-9 group ) . Another 30 patients received 12 intravesical instillations of 40 mg hyaluronic acid every 2 weeks ( hyaluronic acid-12 group ) . Symptomatic changes after hyaluronic acid treatments were assessed using Interstitial Cystitis Symptom and Problem Indexes , pain visual analog scale , functional bladder capacity , frequency and nocturia in voiding diary , maximum flow rate , voided volume , postvoid residual volume , and Quality of Life Index at 1 , 3 and 6 months . RESULTS Of the 60 patients , 59 were evaluable at the end of the study . The Interstitial Cystitis Symptom Index , Interstitial Cystitis Problem Index and total score , pain visual analog scale , functional bladder capacity , maximum flow rate , and Quality of Life Index improved significantly after 6 months in both groups . The frequency and voided volume improved significantly only in the hyaluronic acid-12 group . However , patients with moderate and marked improvement were clinical ly similar in both groups . The measured variables did not differ between the two groups over the course of the study . CONCLUSION No significant difference was noted in the therapeutic effect between two hyaluronic acid instillation regimens for treatment of interstitial cystitis/painful bladder syndrome patients . Both groups showed significant improvement in symptom scores and Quality of Life Index OBJECTIVE To evaluate the therapeutic efficacy of intravesical pentosanpolysulphate ( PPS ) compared with placebo in patients with interstitial cystitis ( IC ) . PATIENTS AND METHODS Twenty patients who fulfilled the diagnostic criteria for IC participated in a double-blind placebo-controlled study ; 10 received intravesical PPS ( 300 mg in 50 mL of 0.9 % sodium chloride ) applied twice a week for 3 months and the other 10 received a placebo .  Symptomatic relief and objective variables ( bladder capacity voiding volumes and urinary frequency ) were assessed after 3 months and the long-term outcome of those continuing treatment was determined . RESULTS Of the patients treated with PPS , four gained significant symptomatic relief compared with only two receiving placebo . Only the urodynamic bladder capacity showed a statistically significant increase in patients treated with PPS ( P = 0.047 ) . At 18 months from the start of the study , the symptoms were relieved in eight patients while still receiving PPS instillations and in four without treatment . CONCLUSIONS These results suggest that intravesical PPS is an effective option for the treatment of IC and shows that the intravesical application of PPS is a safe treatment with no important side-effects Objectives : The aim of this study was to verify the efficacy and safety of intravesical treatment combining sodium hyaluronate ( HA ) and chondroitin sulfate ( CS ) in patients with interstitial cystitis/bladder pain syndrome ( IC/BPS ) . Methods : Between February 2010 and May 2011 , 20 consecutive women with IC/BPS were treated with intravesical instillations containing sodium HA ( 1.6 % ; 800 mg/50 ml ) and sodium CS ( 2 % ; 1 g/50 ml ) weekly for the first month , biweekly for the second month , and then monthly for at least 3 months . Before and after treatment , all patients filled in the Interstitial Cystitis Symptom Index and Problem Index ( ICSI/ICPI ) , the Patient Health Question naire 9 and the Pelvic Pain and Urgency/Frequency Patient Symptom Scale ( PUF ) . Treatment efficacy was assessed by comparing the pre- and post-treatment mean scores of the three question naires using Student ’s t test ( p value < 0.05 was considered significant ) . Results : Statistically significant mean decreases in ICSI ( from 13.0 to 9.3 ; p = 0.0003 ) , ICPI ( from 11.35 to 8.85 ; p = 0.0078 ) and PUF ( from 20.0 to 15.75 ; p = 0.0007 ) question naire scores were seen . No cases of side effects or complications were observed . The mean follow up was 5 months . Conclusions : Despite the limitations of this study , the outcomes confirmed the role of combination therapy with HA and CS as a safe and effective option for the treatment of IC/BPS . Further r and omized controlled studies with a higher number of patients and a longer follow-up period are needed to confirm these results PURPOSE We assess the efficacy of intravesical administration of oxybutynin chloride in patients with interstitial cystitis . MATERIAL S 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 exp and ing the bladder , and an additional statistically significant improvement is evident with intravesical oxybutynin PURPOSE We evaluated the safety and efficacy of intravesical liposomes , a mucosal protective agent , compared to oral pentosan polysulfate sodium for interstitial cystitis/painful bladder syndrome . MATERIAL S AND METHODS We performed a prospect i ve longitudinal study of the effect of 2 independent treatments ( intravesical liposomes and oral pentosan polysulfate sodium ) in patients with interstitial cystitis/painful bladder syndrome . Ten possible responses ( or measures ) to treatment were monitored at 3 time points , including baseline , and weeks 4 and 8 . A total of 24 patients with interstitial cystitis/painful bladder syndrome were evaluated in a 1:1 ratio to intravesical liposomes ( 80 mg/40 cc distilled water ) once weekly or to oral pentosan polysulfate sodium ( 100 mg ) 3 times daily for 4 weeks each . RESULTS No patient had urinary incontinence , retention or infection due to liposome instillation . There were no unanticipated adverse events and no significant worsening of symptoms during followup . Statistically significant decreases in urinary frequency and nocturia were observed in each treatment group . Statistically significant decreases in pain , urgency and the O'Leary-Sant symptom score were observed in the liposome group . Decreased urgency in the liposome group had the most profound effect of the ordinal measures . CONCLUSIONS Each glycosaminoglycan directed treatment seemed beneficial . Liposome intravesical instillation is safe for interstitial cystitis/painful bladder syndrome with potential improvement after 1 course of therapy for up to 8 weeks . Intravesical liposomes achieved efficacy similar to that of oral pentosan polysulfate sodium . Further large-scale placebo controlled studies are needed . Intravesical liposomes appear to be a promising new treatment for interstitial cystitis/painful bladder syndrome OBJECTIVES To test the efficacy of a new intravesical therapeutic solution in relieving urgency/frequency and pain in interstitial cystitis ( IC ) . METHODS A solution of 40,000 U heparin , 8 mL 1 % lidocaine ( 80 mg ; group 1 ) or 2 % lidocaine ( 160 mg ; group 2 ) , and 3 mL 8.4 % sodium bicarbonate was administered intravesically in patients with newly diagnosed IC with significant frequency , urgency , and pain . Using the Patient Overall Rating of Improvement of Symptoms , the response to treatment was evaluated within 20 minutes of instillation in all patients , after 24 to 48 hours in group 2 , and after three treatments per week for 2 weeks in group 2 patients who elected to receive additional instillations . Significant symptom relief was defined as 50 % or greater symptom improvement . RESULTS After one instillation , 35 ( 75 % ) of 47 patients in group 1 ( 1 % lidocaine ) and 33 ( 94 % ) of 35 in group 2 ( 2 % lidocaine ) reported significant immediate symptom relief . The difference in the response rates was statistically significant ( P < 0.01 ) . In group 2 , 50 % of the subjects experienced at least 4 hours of symptom relief from the single instillation , and 16 ( 80 % ) of 20 reported significant sustained symptom relief after 2 weeks of treatment . CONCLUSIONS Intravesical treatment with combined heparin and alkalinized lidocaine immediately reduced the pain and urgency of IC in most patients treated for newly diagnosed IC . Symptom relief lasted beyond the duration of the local anesthetic activity of lidocaine , suggesting the solution suppresses neurologic upregulation . In IC treatment , this new intravesical solution may be helpful in the interval before heparinoid therapy reaches its full effect Introduction and hypothesisIntravesical instillations of hyaluronic acid ( HA ) and chondroitin sulfate ( CS ) may lead to regeneration of the damaged glycosaminoglycan layer in interstitial cystitis/bladder pain syndrome ( IC/BPS ) . Methods Twenty-two patients with IC/BPS received intravesical instillations ( 40 ml ) of sodium HA 1.6 % and CS 2.0 % in 0.9 % saline solution ( IALURIL ® , IBSA ) once weekly for 8 weeks , then once every 2 weeks for the next 6 months . Results The score for urgency was reduced from 6.5 to 3.6 ( p = 0.0001 ) , with a reduction in pain scores from an average of 5.6 to 3.2 ( p = 0.0001 ) . The average urine volume increased from 129.7 to 162 ml ( p < 0.0001 ) , with a reduction in the number of voids in 24 h , from 14 to 11.6 ( p < 0.0001 ) . The IC Symptom and Problem Index decreased from 25.7 to 20.3 ( p < 0.0001 ) , and the Pain Urgency Frequency score , from 18.7 to 12.8 ( p < 0.0001 ) . Conclusion The treatment appeared to be effective and well tolerated in IC/BPS in this initial experience INTRODUCTION To assess the impact of intravesically injected botulinum A toxin ( BoNT/A ) upon bladder pain , urological complaints , symptoms of anxiety and depression , and Quality of Life ( QoL ) in patients with painful bladder symptoms ( PBS ) refractory to conventional treatment . PATIENTS AND METHODS In this prospect i ve study 14 patients received one injection of BoNT/A ( 200 U diluted in 20 ml 0.9 % NaCl ) , under cystoscopic guidance . At pre- and 3 months post- treatment all patients underwent an urological assessment ( voiding diary , urodynamics ) , a pain quantification on a visual analog scale ( VAS ) , an evaluation with the 14-item Hamilton Anxiety Rating Scale ( HAM-A ) to assess symptoms of psychic and somatic anxiety , an evaluation with the Hamilton Depression Rating Scale ( HAM-D ) to assess depression , and the 36-item Medical Outcomes Study Short Form ( SF-36 ) to assess QoL. Results . At pre-treatment all 14 patients had increased daytime and nighttime urinary frequency and high VAS scores . Nine patients had pathological HAM-A scores and all had pathological HAM-D scores . At the 3-month follow-up 10/14 patients reported a subjective improvement in pain . Mean VAS score , mean daytime and nighttime urinary frequency decreased significantly ( p < 0.01 , < 0.01 and < 0.01 , respectively ) . All domains in SF-36 and HAM-A significantly improved ( p<0.01 ) . All domains , except weight and sleep disorders , significantly improved in HAM-D , particularly somatoform symptoms ( p<0.01 ) , cognitive performance ( p<0.01 ) , and circadian variations ( p<0.01 ) . CONCLUSION In patients with refractory PBS with symptoms of anxiety , depression and poor QoL , BoNT/A intravesical treatment reduced bladder pain , improved psychological functioning , and well-being OBJECTIVES The aim of our study was to test the effect of a more viscous compound than existent hyaluronic acid formulation in helping to restore a defective glycosaminoglycan layer , and therefore in improving Interstitial Cystitis/Painful Bladder Syndrome ( IC/PBS ) symptoms when administered intravesically in IC/PBS patients . METHODS A total of 23 female patients completed the study . Patients received endovesical administration of hyaluronic acid and chondroitin sulfate in normal saline , 40 ml , weekly for 12 weeks and then bi-weekly for 6 months , if there was initial response . RESULTS After 12 weeks treatment both Interstitial Cystitis Symptom and Problem Index ( ICSI/ICPI ) , pelvic pain and Urgency/Frequency Symptom Scale ( PUF ) showed a mean significant improvement , which was maintained thereafter . The average number of voidings and mean voiding volumes revealed significant improvement after the 12 weeks ' treatment period , with a significant reduction and increase , respectively . Mean voiding volume increased from 143 ml to 191 , which apparently was not reflected in a corresponding reduction of number of daily voids ( from 15,5 to 14 ) . VAS values decreased from 5,4 to 3,6 ( pain ) and from 6,0 to 3,5 ( urgency ) after the treatment cycle , showing a significant improvement . CONCLUSIONS In our preliminary experience , the administration of intravesical hyaluronic acid plus chondroitine sulphate appears to be a safe and efficacious method of treatment in IC/PBS To assess the immediate and sustained relief of the symptoms of interstitial cystitis/painful bladder syndrome ( IC/PBlS ) after a consecutive 5‐day course of treatment with intravesical alkalinized lidocaine ( PSD597 ) , and to characterize the pharmacokinetics of single and multiple doses of intravesical PSD597 in a subgroup of patients
Meta- analysis of BCG therapy showed improvement in symptoms according to the Wisconsin Interstitial Cystitis Symptom Inventory , but no difference in 24-h urinary frequency .
Conclusions Meta- analysis showed an improvement exclusively of the symptoms as measured by the Wisconsin Interstitial Cystitis Inventory , but not in 24-h urinary frequency , with BCG therapy .
Introduction and hypothesisThe objective of the study was to assess the effectiveness of intravesical treatment for painful bladder syndrome ( PBS ) .
