Inflammation is responsible of irritative symptoms; it issupposed the existence of an arterial obstructive disease connected with bladder ischaemia. Direct bacterial damage and/orinflammation are responsible of the activation of ROS (radicals of oxygen) and consequent cell damage. NF-kB protein is protagonistin ROS synthesis. High levels of 02 in periphereal tissues reduce ischaemia, responsible of recurrent inflammation and increaseantioxidant effects in presence of controlled oxidation. The aim of this study is the essay of anti-inflammatory effects of OOT(oxygen-ozone therapy) in chronic cystitis, employed in combined subministration. OOT properties could decrease bacterialconcentration and eliminate dysuriac disturbances, reducing ischaemic effects. Methods: This study proposes a combined treatment forcystitis with oxygen-ozone AHTM (autohaemotherapy) and intravescical insufflations. It has been selected 8 Women aged 40-55 yearswith recurrent cystitis, associated with pain and urge incontinence. We have used certified medical OOT generator. Results: Aftertherapies, all patients showed sterile urine and progressive reduction of symptoms with a sensible improvement of quality of life.Conclusions: Nevertheless, in a little group of patients, preliminary results could suggest the use of OOT for recurrent cystitis afterfailure of conventional therapies.展开更多

The predisposition of diabetic patients to urinary infections caused by gas-producing bacteria is considered one of the most common factors in the occurrence of emphysematous cystitis. The currently recommended diagnostic test is CT scanning, which has definite value in assessing gas accumulation in the bladder wall and lumen. The authors report the observations of two patients aged 68 and 80 who were treated for emphysematous cystitis complicating diabetes mellitus.

Among them, 72 cases were subjected to bacterial counting culture of urine and microscopic examination of urinary sediment, and 60 cases to fluorescence quantitative polymerase chain reaction (FQ-PCR) assay to detect HPV, CMV and HSV DNA in urine samples. In the 72 cases of CG, the positive rate of bacterial counting culture of urine was 15.3 % (11/72), and gray zone rate was 18.1 % (13/72). 31.9 % (23/72) patients were positive in bacterioscopy of urinary sediment. There was statistically significant difference as compared with the control group (P<0.01). Only 4 of 60 urine samples were positive by FQ-PCR in detection of the three viruses mentioned above with the positive rate being 6.67 %. Compared with the control group, there was no significant difference (P>0.05). It was concluded that the genesis of CG was closely correlated with the chronic lower urinary tract infection, especially caused by Esch coli.展开更多

No intervention was given to the rats in the blank group. NS was infused into the bladder of the rats of the control group, and solution containing E. coil was injected into the bladder of experimental group. Three months later, tissue samples of bladder were collected and observed visually and under light microscope. The results showed that tissues of the blank group were normal', one sample in the control group showed Brunn's nests and cystitis cystica, and 10 in the experimental group had the change of cystitis glandularis. Compared to the blank and control group, samples in the experimental group showed significant change (P〈0.05). There were no significant difference between blank group and control group (P〉0.05). It is concluded that bladder instillation of E. coil can induce cystitis glandularis, which confirms that infection is the cause of cystitis glandularis.展开更多

All the cases were immunohistochemically examined by using antibodies specifically against p53 and PCNA, and hTERT was determined by in situ hybridization. hTERT was found in 6 cases (33.3%) and p53 was detected in 4 cases (22.2%) in group A, while they were not detected in group B. There were significant differences in hTERT and p53 expression between groups A and B (P〈0.05 for both). PCNA was detected in 7 cases (38.9%) in group A and 1 case (5.0%) in group B, and significant difference in PCNA expression was found between the two groups (P〈0.05). The expressions of hTERT, p53 and PCNA were significantly higher in group A than in group B, suggesting that papillary cystitis glandularis is predisposed to cancerous change, and p53, PCNA, hTERT may be related to the malignant alteration.展开更多

Patients and methods: Five female patients (40 - 71 years old) diagnosed as interstitial cystitis by cystoscopic findings and a 68 year-old bladder pain syndrome patient were enrolled. All patients, having interstitial cystitis, had undergone hydrodistention therapy previously and had not improved their symptoms by empirical therapies. Daily or weekly (upon their severity of symptoms) intravesical instillation of 20 ml of 4% non-alkalinized (pH 6.0 - 7.0) lidocaine solution was performed for several times, and patients were asked to keep them in the bladder as long as two hours each time. Previous medications such as anti-cholinergic drugs and analgesics were continued according to patient's requirements and symptoms. The treatment effect was evaluated comparing O'Leary-Sant Symptom Index for interstitial cystitis patients and visual analog pain scale before and after the series of lidocaine therapies. Results: Instillation was made 6 to 16 times. Patients with interstitial cystitis improved their symptoms from O'Leary-Sant Symptom Index 17.5 to 10, Problem Index from 14.8 to 6 in an average. Crouching pain disappeared in all these patients after the instillation therapy. Severe interstitial cystitis findings on cystoscopy disappeared completely in one patient after the therapy. One patient having bladder pain syndrome reduced her analgesics use, and bladder-filling pain decreased from 7 to 3 as a visual analog scale score. One patient complained palpitation at 11th instillation and abandoned treatment thereafter, otherwise, none of these patients showed side effect concerning lidocaine toxicity. Conclusions: Intravesical non-alkalinized lidocaine instillation therapy for interstitial cystitis/bladder pain syndrome patients were an easy, safe and effective treatment.展开更多

Methods: There were 6 rat treatment groups (n = 8 per group): control + single or daily saline infusion, tranilast + single or daily saline infusion, and tranilast + single or daily budesonide infusion. All groups except for the controls were fed a tranilast supplemented diet for 5 weeks. Budesonide and saline were infused intravesically. After the BPS/IC rat model underwent single infusion treatments, we measured the paw pain threshold using the von Frey test and continuous cystometry was taken. After two weeks of daily intravesical infusions, we measured locomotor activity and serum cortisol levels;harvested bladders underwent histological analysis. Results: Both pain threshold and locomotor activity were significantly lower in the saline-infused groups receiving the tranilast diet, but there were no differences between the budesonide-infused groups and the controls. The interval between bladder contractions was significantly shorter in the tranilast group than the control or tranilast + budesonide infusion groups. The serum cortisol levels did not change. Hematoxylin-Eosin stainings of the bladder showed thickening of the bladder muscle layer and mucosal edema in the tranilast group, while the tranilast + budesonide infusion group showed only mild changes. Conclusion: Intravesical infusion of budesonide effectively treated BPS/IC symptoms in a rat model of BPS/IC.展开更多

The theory is that the increased dissolved oxygen in the blood raises the levels of oxygen in the tissues and improves tissue healing. Other urological disorders such as radiation cystitis, Fournier’s gangrene and cyclophosphamide cystitis have also shown a good response to HBO therapy. Method: A literature search with the terms “interstitial cystitis”, “painful bladder syndrome” and “hyperbaric oxygen therapy” found four papers that have trialed HBO therapy in IC patients;three case series and one randomized control trial. Results: A total of 31 patients have been treated with HBO therapy. All four studies show a symptomatic improvement in pain, urgency, bladder capacity and O’Leary-Sant interstitial cystitis index. Urinary frequency only improved in three out of four of the trials. The percentage of patients considered as responders to treatment varied at 25%, 66.7%, 82% and 100%. Conclusion: Preliminary trials of HBO therapy seem to have a good patient response with effective symptomatic relief. The patient response rates varied greatly between the trials. This is due to each trial’s different definition of a “patient responder”. Further work in urology departments at HBO centers is required to further assess the benefits of HBO treatment in IC.展开更多

XC is a unique disease in which there have been only 26 cases described in the literature, including our case. Patients with XC often present with lower urinary tract symptoms, hematuria, abdominal pain, or abdominal mass. We present the unusual case of an 81 year old female who presents with urinary incontinence, which was later diagnosed as a vesicovaginal fistula. After describing the treatment of this patient, a review of the literature is detailed including presentation, possible etiologies, and treatment of XC.展开更多

文摘To examine the expression of human telomere reverse transcriptase (hTERT), p53 and proliferating cell nuclear antigen (PCNA) in cystitis glandulafis, 38 patients were divided into two grouips: group A (including 18 cases of papillary cystitis glandularis) and group B (including 20 subjects with normal bladder mucosa). All the cases were immunohistochemically examined by using antibodies specifically against p53 and PCNA, and hTERT was determined by in situ hybridization. hTERT was found in 6 cases (33.3%) and p53 was detected in 4 cases (22.2%) in group A, while they were not detected in group B. There were significant differences in hTERT and p53 expression between groups A and B (P〈0.05 for both). PCNA was detected in 7 cases (38.9%) in group A and 1 case (5.0%) in group B, and significant difference in PCNA expression was found between the two groups (P〈0.05). The expressions of hTERT, p53 and PCNA were significantly higher in group A than in group B, suggesting that papillary cystitis glandularis is predisposed to cancerous change, and p53, PCNA, hTERT may be related to the malignant alteration.
文摘Interstitial cystitis/bladder pain syndrome(IC/BPS)is a debilitating,chronic condition characterized by chronic pelvic pain,urinary urgency,and frequency and is well-known to be associated with a decrease in work productivity,emotional changes,sleep,sexual dysfunction,and mobility.Many metrics of quality of life(QoL)in this patient population have been developed;however,a unified,standardized approach to QoL in these patients has not been determined.The effects of IC/BPS and co-morbid conditions on QoL are described using current validated metrics.Next,data regarding successful treatment of IC/BPS in terms of QoL improvement are reviewed.While QoL is the single most important clinical measure of success in the treatment of patients suffering from IC/BPS,addressing QoL in this patient population remains a significant challenge,as its effects on QoL are highly variable and unable to be differentiated from the effects of comorbid conditions on QoL,including depression,poor sleep,and inability to work.Future studies will need to address treatment efficacy on the basis of IC/BPS specific QoL metrics,and multi-modal assessment and therapy to address comorbid disease will also play an important role in the future to ensure comprehensive management of these patients.

文摘BACKGROUND Pelvic lipomatosis(PL)is a rare benign condition with characteristic overgrowth of histologically benign fat and invasion and compression of pelvic organs,often leading to non-specific lower urinary tract symptoms(LUTS).Approximately 40%of patients with PL have cystitis glandularis(CG).The cause of PL combined with CG is poorly understood,and there is currently no effective treatment.Refractory CG with upper urinary tract obstruction even requires partial or radical bladder resection.CASE SUMMARY In this case,a patient suffering from PL with CG was treated by transurethral resection of bladder tumour(TUR-BT)and oral administration of celecoxib,a selective cyclooxygenase-2(COX-2)inhibitor.The LUTS were alleviated,and the cystoscopy results improved significantly.Immunohistochemistry showed upregulated COX-2 expression in the epithelium of TUR-BT samples,suggesting that COX-2 may participate in the pathophysiological process of PL combined with CG.CONCLUSION We report for the first time that celecoxib may be an effective treatment strategy for PL combined with refractory CG.
文摘BACKGROUND Encrusted cystitis(EC)is a chronic inflammation of the bladder associated with mucosal encrustations.Early diagnosis and optimal treatment are not well established.Here,we report a case of EC successfully treated with com-bination therapy.CASE SUMMARY A 27-year-old man presented with frequency,urgency,dysuria,gross hematuria and suprapubic pain for 2 mo.He was diagnosed with EC based on characteristic calcifications of the bladder wall(most of them were struvite),cystoscopy and histopathological examination.He was cured after combined therapy of elimination of encrustations,bladder instillation of hyaluronic acid and injection of botulinum-A neurotoxin into bladder submucosal tissue.CONCLUSION Bladder instillation of hyaluronic acid and injection of botulinum-A neurotoxin into the bladder submucosal tissue can be used for treatment of EC.
文摘Purpose: The effectiveness of daily or weekly instillation of non-alkalinized lidocaine for patients suffering interstitial cystitis and/or bladder pain syndrome was evaluated retrospectively. Patients and methods: Five female patients (40 - 71 years old) diagnosed as interstitial cystitis by cystoscopic findings and a 68 year-old bladder pain syndrome patient were enrolled. All patients, having interstitial cystitis, had undergone hydrodistention therapy previously and had not improved their symptoms by empirical therapies. Daily or weekly (upon their severity of symptoms) intravesical instillation of 20 ml of 4% non-alkalinized (pH 6.0 - 7.0) lidocaine solution was performed for several times, and patients were asked to keep them in the bladder as long as two hours each time. Previous medications such as anti-cholinergic drugs and analgesics were continued according to patient's requirements and symptoms. The treatment effect was evaluated comparing O'Leary-Sant Symptom Index for interstitial cystitis patients and visual analog pain scale before and after the series of lidocaine therapies. Results: Instillation was made 6 to 16 times. Patients with interstitial cystitis improved their symptoms from O'Leary-Sant Symptom Index 17.5 to 10, Problem Index from 14.8 to 6 in an average. Crouching pain disappeared in all these patients after the instillation therapy. Severe interstitial cystitis findings on cystoscopy disappeared completely in one patient after the therapy. One patient having bladder pain syndrome reduced her analgesics use, and bladder-filling pain decreased from 7 to 3 as a visual analog scale score. One patient complained palpitation at 11th instillation and abandoned treatment thereafter, otherwise, none of these patients showed side effect concerning lidocaine toxicity. Conclusions: Intravesical non-alkalinized lidocaine instillation therapy for interstitial cystitis/bladder pain syndrome patients were an easy, safe and effective treatment.
文摘Purpose: Since intravesically administered steroid therapy may treat bladder pain syndrome/interstitial cystitis (BPS/IC) with fewer side effects than the current treatment of orally administered steroids, we investigated whether the intravesical infusion of budesonide foam can effectively treat BPS/IC symptoms in a rat model of tranilast-induced BPS/IC. Methods: There were 6 rat treatment groups (n = 8 per group): control + single or daily saline infusion, tranilast + single or daily saline infusion, and tranilast + single or daily budesonide infusion. All groups except for the controls were fed a tranilast supplemented diet for 5 weeks. Budesonide and saline were infused intravesically. After the BPS/IC rat model underwent single infusion treatments, we measured the paw pain threshold using the von Frey test and continuous cystometry was taken. After two weeks of daily intravesical infusions, we measured locomotor activity and serum cortisol levels;harvested bladders underwent histological analysis. Results: Both pain threshold and locomotor activity were significantly lower in the saline-infused groups receiving the tranilast diet, but there were no differences between the budesonide-infused groups and the controls. The interval between bladder contractions was significantly shorter in the tranilast group than the control or tranilast + budesonide infusion groups. The serum cortisol levels did not change. Hematoxylin-Eosin stainings of the bladder showed thickening of the bladder muscle layer and mucosal edema in the tranilast group, while the tranilast + budesonide infusion group showed only mild changes. Conclusion: Intravesical infusion of budesonide effectively treated BPS/IC symptoms in a rat model of BPS/IC.
文摘Follicular cystitis is a non-specific inflammatory condition of the bladder where the aetiology is unknown.The extent of the disease can be mild or proliferative and bulky.Antibiotics,steroids,therapies used for interstitial cystitis,palliative cystectomy and radiotherapy have been reported as successful treatment options.We report a case of follicular cystitis that responded to a course of oral diethyl carbamazine.
文摘BACKGROUND Nearly-complete labial adhesions diagnosed with repetitive cystitis in postmenopausal women:A case report CASE SUMMARY The case of an 83-year-old woman who presented with dysuria,urination disorders,recurrent cystitis,and bacteriuria and was admitted to a private hospital after 1 mo of antibiotic treatment without improvement of her symptoms.Upon examination,labial adhesions were observed with nearly-complete labial fusion with a pinpoint opening.Bacteriuria was detected in urine analysis,and the urine culture test was positive for Escherichia coli.Therefore,a parenteral antibiotic(Fosfomycin)and topical estrogen cream were administered.However,since the adhesion did not separate after 2 wk of treatment,surgical correction was performed.First,adhesiolysis was conducted with a blunt instrument.Then,hysteroscopy and cystoscopy were performed.Hysteroscopic findings showed no abnormalities of the endometrium and endocervix,and the cystoscopic results were also normal.Finally,labiaplasty was completed to prevent adhesion recurrence.One month after the surgery,the discomfort while urinating was eliminated and the adhesion did not recur.CONCLUSION Labial adhesions in postmenopausal women cannot be successfully treated with estrogen creams,and surgical treatment should be considered.
文摘BACKGROUND Portal venous gas(PVG)is a rare clinical condition usually indicative of severe disorders,including necrotizing enterocolitis,bowel ischemia,or bowel wall rupture/infarction.Pneumatosis intestinalis(PI)is a rare illness characterized by an infiltration of gas into the intestinal wall.Emphysematous cystitis(EC)is relatively rare and characterized by intramural and/or intraluminal bladder gas best depicted by cross-sectional imaging.Our study reports a rare case coexistence of PVG presenting with PI and EC.CASE SUMMARY An 86-year-old woman was admitted to the emergency room due to the progressive aggravation of pain because of abdominal fullness and distention,complicated with vomiting and stopping defecation for 4 d.The abdominal computed tomography(CT)plain scan indicated intestinal obstruction with ischemia changes,gas in the portal vein,left renal artery,superior mesenteric artery,superior mesenteric vein,some branch vessels,and bladder pneumatosis with air-fluid levels.Emergency surgery was conducted on the patient.Ischemic necrosis was found in the small intestine approximately 110 cm below the Treitz ligament and in the ileocecal junction and ascending colon canals.This included excision of the necrotic small intestine and right colon,fistulation of the proximal small intestine,and distal closure of the transverse colon.Subsequently,the patient displayed postoperative short bowel syndrome but had a good recovery.She received intravenous fluid infusion and enteral nutrition maintenance every other day after discharge from the community hospital.CONCLUSION Emergency surgery should be performed when CT shows signs of PVG with PI and EC along with a clinical situation strongly suggestive of bowel ischemia.

文摘BACKGROUND Paraneoplastic neurological syndrome(PNS)is an unusual event.PNS caused by cystitis glandularis(CG)or a bladder tumor is extremely rare;hence,missed diagnosis or misdiagnosis can easily occur.To date,approximately 21 cases have been reported in PubMed.CASE SUMMARY We report a case of PNS caused by CG and describe the clinical and imaging features.The main clinical feature was advanced cognitive impairment,and early clinical features were memory impairment,decreased computational ability,and abnormal behavior.Later clinical features were dementia,vomiting,inability to eat and walk,urinary incontinence,and hematuria.Imaging features on cranial magnetic resonance imaging were diffuse white matter lesions.Paraneoplastic tumor markers were normal.A total abdominal computed tomography scan showed multiple thickened areas on the bladder wall with local prominence.Cystoscopy revealed a volcanic protuberance on the posterior wall of the bladder with a diameter of 6 cm and no pedicle.The postoperative pathological diagnosis was CG.The patient recovered well following resection of CG.PNS cases caused by previous bladder tumors can be retrieved from PubMed to describe the clinical signs and prognosis of PNS.CONCLUSION The main clinical feature of PNS caused by CG was dementia,and the imaging features were diffuse cerebral white matter lesions.Resection of CG lesions is the fundamental treatment for PNS induced by CG.This case highlights the importance of etiological treatment.
文摘Introduction: Hyperbaric oxygen therapy (HBO) is emerging as an alternative technique for treating refractory interstitial cystitis (IC). The theory is that the increased dissolved oxygen in the blood raises the levels of oxygen in the tissues and improves tissue healing. Other urological disorders such as radiation cystitis, Fournier’s gangrene and cyclophosphamide cystitis have also shown a good response to HBO therapy. Method: A literature search with the terms “interstitial cystitis”, “painful bladder syndrome” and “hyperbaric oxygen therapy” found four papers that have trialed HBO therapy in IC patients;three case series and one randomized control trial. Results: A total of 31 patients have been treated with HBO therapy. All four studies show a symptomatic improvement in pain, urgency, bladder capacity and O’Leary-Sant interstitial cystitis index. Urinary frequency only improved in three out of four of the trials. The percentage of patients considered as responders to treatment varied at 25%, 66.7%, 82% and 100%. Conclusion: Preliminary trials of HBO therapy seem to have a good patient response with effective symptomatic relief. The patient response rates varied greatly between the trials. This is due to each trial’s different definition of a “patient responder”. Further work in urology departments at HBO centers is required to further assess the benefits of HBO treatment in IC.
文摘Anthogranulomatous cystitis (XC) is an inflammatory condition of the urinary bladder that is benign and rarely seen. XC is a unique disease in which there have been only 26 cases described in the literature, including our case. Patients with XC often present with lower urinary tract symptoms, hematuria, abdominal pain, or abdominal mass. We present the unusual case of an 81 year old female who presents with urinary incontinence, which was later diagnosed as a vesicovaginal fistula. After describing the treatment of this patient, a review of the literature is detailed including presentation, possible etiologies, and treatment of XC.
