Preliminary results of suburothelial injection of botulinum a toxin in the treatment of chronic interstitial cystitis.

PURPOSE: Treatment of interstitial cystitis is usually not successful in eradicating bladder pain and increased bladder capacity. This study was designed to evaluate the clinical effectiveness of suburothelial injection of botulinum A toxin in patients with chronic interstitial cystitis. METHODS: Eight women and 2 men with chronic interstitial cystitis who had failed conventional treatments were enrolled in this study. In 5 patients, 100 units of botulinum A toxin was injected suburothelially into 20 sites, and an additional 100 units was injected into the trigone in the other 5 patients. Therapeutic outcome including functional bladder capacity, number of daily urinations, bladder pain, and urodynamic changes were compared between baseline and 3 months after treatment. RESULTS: In 2 patients bladder pain and urinary frequency were improved 3 months after treatment. Mild difficulty in urination was reported by 7 patients. Functional bladder capacity recorded in a voiding diary was significantly increased (155+/-26.3 vs. 77+/-27.1 ml, p<0.001), and the frequency of daily urinations (18+/-7.7 vs. 24.2+/-10.3, p=0.025) and the pain score (2.4+/-1.6 vs. 3.2+/-1.1, p=0.003) were mildly but significantly reduced after treatment. Only the cystometric capacity improved significantly (287+/-115 vs. 210+/-63.8 ml, p=0.05) in urodynamic results. Trigonal injection had no therapeutic effect on symptom or urodynamic improvement. No adverse effect was reported. CONCLUSIONS: The clinical result of suburothelial botulinum A toxin injection was disappointing. None of the patients was symptom free and only a limited improvement in bladder capacity and pain score was achieved in 2 patients.

Treatment of radiation-induced hemorrhagic cystitis with laparoscopic cystoprostatectomy.

Hemorrhagic cystitis can occur 6 months to 10 years after pelvic irradiation. Various palliative treatment alternatives may be unsuccessful in the management of severe hemorrhagic cystitis, so that in rare cases radical surgery will be the last resort.A 77-year-old man with persistent bleeding due to hemorrhagic cystitis after radiotherapy for prostate cancer was initially treated with conservative measures. All of these treatment methods were unsuccessful. His condition deteriorated and became life-threatening. As a last resort, laparoscopic cystoprostatectomy and mini-laparotomy ileal conduit diversion were successfully performed with no intraoperative or postoperative complications. To our knowledge, this is the first report on laparoscopic cystoprostatectomy for a patient with previous radiotherapy to the pelvis.

Acute hemorrhagic cystitis caused by adenovirus type 11 after renal transplantation.

A case of acute hemorrhagic cystitis caused by adenovirus type 11, which occurred in an allograft recipient 6 months after a living-related renal transplantation, is described. The patient lacked a neutralizing antibody to adenovirus type 11 before transplantation. Adenovirus type 11 was isolated from his urine and he developed a neutralizing and complement-fixing antibody to this virus. Although adenovirus type 11 isolates had been obtained from 2 of 18 renal allograft recipients, only 1 patient suffered acute hemorrhagic cystitis. Adenovirus type 11 may play a role in acute hemorrhagic cystitis in renal allograft recipients during immunosuppressive therapy.

Rational use of antibiotics in acute uncomplicated cystitis: a pharmaco-epidemiological study.

Uncomplicated community-acquired urinary tract infections are among those most commonly found in clinical practice, resulting in significant morbidity and health care costs. Current management is usually empirical because of the narrow and predictable spectrum of etiologic agents that cause acute cystitis and their susceptibility patterns. However, since antimicrobial resistance is increasing, the use narrow-spectrum, inexpensive antimicrobial agents becomes less feasible. In our study we have evaluated the effectiveness of amoxicillin, a narrow-spectrum, inexpensive and non toxic drug, against non-complicated acute cystitis in 34 patients, and compared the results with the antibiotic therapy previously employed by the physicians of the Health Care Unit of Paola (CS), Italy. Amoxicillin was found to be effective for the treatment of community-acquired cystitis, thus suggesting that the development of bacterial resistance does not represent a limit to its use. Furthermore, our study demonstrates that besides providing an effective alternative to broad-spectrum antibiotics, the use of amoxicillin significantly reduced health care costs.

Is there an ethnic difference in the prevalence of lupus cystitis? A report of six cases.

Lupus cystitis was rare but frequently resulted in obstructive uropathy and had a strong association with gastrointestinal (GI) symptoms. We treated six patients with systemic lupus erythematosus (SLE) and obstructive uropathy from January 1996 to December 2001 in a university hospital. Evidence of cystitis was obtained from cystoscopic biopsy or the presence of thickened bladder wall in image study. Similar to other reports, five patients had GI manifestations such as abdominal pain, nausea/vomiting, diarrhoea or ileus. In addition, mesenteric lymphadenopathy or pancreatitis was noted in three patients. Two patients had been treated for idiopathic thrombocytopenic purpura (ITP), four and 20 years ago, respectively. All six patients had antibodies to double-stranded DNA (dsDNA). Five patients each had antibodies to cardiolipin (IgG aCL) or SSA. The high prevalence of anti-SSA had also been reported in Chinese lupus patients with intestinal pseudo-obstruction, a clinical manifestation frequently associated with bilateral ureterohydronephrosis. Two patients died of intractable infection after the surgical procedures for persistent ureterohydronephrosis and both patients had antibodies to ribosomal P proteins. Lupus cystitis might not be so rare in Chinese patients with SLE. The diagnosis should be kept in mind when lupus patients have urinary and/or GI symptoms.

Cyclophosphamide-induced hemorrhagic cystitis in Ewing's sarcoma.

Recent improvements in survival of patients with Ewing's sarcoma have been made since the addition of cyclophosphamide-based adjuvant chemotherapy to primary surgery and radiation. A potential limitation to cyclophosphamide use is its urotoxicity, primarily in the form of hemorrhagic cystitis. The incidence of this adverse effect in patients treated for Ewing's sarcoma has not been established. In a Mayo Clinic series of 116 patients with Ewing's sarcoma treated with cyclophosphamide, 17 (15%) developed hemorrhagic cystitis diagnosed on the basis of gross hematuria or cystoscopic findings (or both). Microscopic hematuria also occurred in 53% of patients (56 of 105 examined). The dose and duration of therapy appeared to be unrelated to the development of urotoxicity. Most patients recovered uneventfully with or without discontinuation of cyclophosphamide therapy, but a significant loss of blood occurred in three patients, and one patient required a cystectomy because of bladder fibrosis. Long-term follow-up is mandatory in these patients because of late recurrences of hemorrhagic cystitis or the possibility of bladder carcinoma. New therapies, directed at protecting the bladder from urotoxicity during cyclophosphamide treatment, are available.

Mesna versus hyperhydration for the prevention of cyclophosphamide-induced hemorrhagic cystitis in bone marrow transplantation.

Hemorrhagic cystitis is a major complication of high-dose cyclophosphamide therapy used in preparation for allogeneic or autologous bone marrow transplantation. Although previous reports had suggested that the sulfhydryl-containing compound mesna might be superior to forced diuresis in preventing hemorrhagic cystitis, there were concerns about the effect of mesna on engraftment in these studies. To address these concerns, 100 patients were randomized to receive mesna or forced saline diuresis while undergoing bone marrow transplant conditioning with regimens that included high-dose cyclophosphamide. To try to minimize the likelihood of graft rejection, patients who were being transplanted with cyclophosphamide as a sole agent were excluded from the study. After randomization and administration of therapy, patients were monitored by microscopic and dip-stick urinalyses; they were also followed for effects of therapy on engraftment. The incidence of consistent or severe hematuria was 33% in the mesna arm and 20% in the hyperhydration arm (P = .31). Severe bleeding occurred in 12.5% of mesna patients and 7.5% of hyperhydration patients (P = .71). No unexpected toxicities were encountered, and engraftment times did not differ. Based on this randomized trial of 100 patients, we conclude that mesna and hyperhydration are equally effective in preventing cyclophosphamide-induced hemorrhagic cystitis in bone marrow transplantation patients.

Cystitis, urolithiasis and cystic calculi in ageing guineapigs.

Nineteen cases of cystitis were diagnosed at necropsy and/or by histology in a group of 170 (96 females, 74 males) guineapigs (11.2%). Seventeen of the 19 cases (89.4%) were females. The mean age of guineapigs with cystitis was 34.7 months, which was higher than the mean age of 24 months of the 170 members of the study group. In addition, 6 cases of urolithiasis and cystic calculi in 5 females and one male were also found in the 170 guineapigs (3.5%). The mean age of the 6 cases was 30 months, which was also higher than the mean age of the 170 animals. The study suggests that aged female guineapigs were much more predisposed to cystitis and urolithiasis or cystic calculi than male and young guineapigs. The cause may be related to infection with Escherichia coli and Staphylococcus sp, cystic calculi, diabetes mellitus and female guineapig urogenital anatomy and function.

Current status in the pharmacological management of interstitial cystitis.

Interstitial cystitis is a clinical condition occurring predominantly in women characterised by irritative voiding symptoms in the form of urinary frequency, urgency and pain. Patient symptoms have the potential to significantly affect quality of life, posing a challenge to some to perform activities of daily living. Those who reach an eventual diagnosis of interstitial cystitis have typically done so through an emotionally charged and circuitous route, the product of numerous physician encounters and stigmatising experiences. As such, these patients require considerate care. Overall, current pharmacological agents for the treatment of those with interstitial cystitis, provide a measure of symptomatic benefit, however, a universally effective regimen remains to be reported. As a definitive disease aetiopathogenesis is not fully determined, trials of pharmacological therapy are ongoing.

A model of hemorrhagic cystitis induced with acrolein in mice.

Acrolein is a urinary metabolite of cyclophosphamide and ifosfamide, which has been reported to be the causative agent of hemorrhagic cystitis induced by these compounds. A direct cytotoxic effect of acrolein, however, has not yet been demonstrated. In the present study, the effects of intravesical injection of acrolein and mesna, the classical acrolein chemical inhibitor, were evaluated. Male Swiss mice weighing 25 to 35 g (N = 6 per group) received saline or acrolein (25, 75, 225 microg) intravesically 3, 6, 12, and 24 h before sacrifice for evaluation of bladder wet weight, macroscopic and histopathological changes by Gray's criteria, and 3 and 24 h for assessment of increase in vascular permeability. In other animals, mesna was administered intravesically (2 mg) or systemically (80 mg/kg) 1 h before acrolein. Intravesical administration of acrolein induced a dose- and time-dependent increase in vascular permeability and bladder wet weight (within 3 h: 2.2- and 21-fold increases in bladder wet weight and Evans blue dye exuded, respectively, at doses of 75 microg/bladder), as confirmed by Gray's criteria. Pretreatment with mesna (2-mercaptoethanesulfonic acid), which interacts with acrolein resulting in an inactive compound, inhibited all changes induced by acrolein. Our results are the first demonstration that intravesical administration of acrolein induces hemorrhagic cystitis. This model of acrolein-induced hemorrhagic cystitis in mice may be an important tool for the evaluation of the mechanism by which acrolein induces bladder lesion, as well as for investigation of new uroprotective drugs.

Non-urotoxic induction of hemorrhagic cystitis by braxin C, a bracken toxin, in guinea pigs.

Single subcutaneous injections of 5 and 10 mg/kg of braxin C (BC), ptaquiloside, a toxin isolated from bracken fern, have been shown to induce hemorrhagic cystitis in guinea pigs. In order to determine whether the hemorrhagic cystitis induced by BC is due to the urotoxic effects or not, BC was administered to the guinea pigs in which the flow of urine to the urinary bladder had been intercepted by cannulation of the ureters under anesthesia. In the animals treated ureteral cannulation, edema and hemorrhage were observed in the urinary bladder following BC administration (10 mg/kg s.c.). These findings suggest that BC induced hemorrhagic cystitis is mediated by hematogenous and not urotoxic factors.

Antimicrobial resistance of Escherichia coli strains isolated from urine of women with cystitis or pyelonephritis and feces of dogs and healthy humans.

OBJECTIVE: To assess the prevalence and patterns of antimicrobial resistance among Escherichia coli strains isolated from the urine of women with cystitis or pyelonephritis and from fecal samples from dogs and healthy humans. DESIGN: Cross-sectional survey. SAMPLE POPULATION: Escherichia coli isolates from 82 women with cystitis, 170 women with pyelonephritis, 45 dogs, and 76 healthy human volunteers. PROCEDURE: Susceptibility to 12 antimicrobial agents was determined by means of disk diffusion testing as specified by the NCCLS. RESULTS: Overall, the 4 most common antimicrobial resistance patterns were resistance to ampicillin, sulfisoxazole, trimethoprim, and trimethoprim-sulfamethoxazole (n = 45 [12% of all isolates]); ampicillin alone (33 [9%]); ampicillin and sulfisoxazole (29 [8%]); and sulfisoxazole alone (14 [4%]). None of the isolates were resistant to ceftazidime, ciprofloxacin, nitrofurantoin, or piperacillin-tazobactam. Resistance was significantly more common and extensive among isolates from women with cystitis or pyelonephritis than among isolates from healthy humans or dogs. Resistance was least common among isolates from dogs. The only resistance phenotype that was more common among canine isolates than human isolates was resistance to sulfisoxazole alone. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that dogs are unlikely to be an important external reservoir of antimicrobial-resistant E. coli strains causing infections in humans. On the contrary the data suggest that dogs conceivably could acquire resistant E. coli strains from humans.

Nonobstructive detrusor myopathy in a group of patients with chronic abacterial cystitis.

Chronic abacterial cystitis is clinically and pathoanatomically an ill-defined condition, presenting with a variety of urologic symptoms and often nonspecific histology. A retrospective histologic analysis of bladder biopsies from 101 patients with chronic abacterial cystitis revealed degenerative changes in the detrusor muscle cells (detrusor myopathy) in 25 of them. The changes were often very severe, and even fatty replacement of muscle tissue was seen. Retrospective analysis of the symptoms, urodynamics and cystoscopic findings in these patients showed that none had haematuria, but five (all women) had had urinary retention requiring catheterization. Significant residual urine was found in nine patients, and the cystometrograms showed a shift to the right. No patient had infravesical obstruction. At cystoscopy less than half of the patients had petechial bleeding after bladder distension. The aetiology and pathogenesis of the degenerative changes are unknown, despite theoretic speculation. The authors conclude that careful histologic examination can identify different clinical types of chronic abacterial cystitis. Such studies may assist future research into the nature of the problem and also the search for more rational therapy.

[A case of proliferative chronic cystitis, progressing to obstructive nephropathy, treated by total cystectomy and enterocystoplasty].

A 52 year-old man, being pointed out as with microscopic hematuria and suspected of carcinoma of the urinary bladder at another institution, visited this hospital for further examination. DIP demonstrated an irregular right lateral wall of the urinary bladder. CT of the pelvic cavity revealed a protrusive mass lesion inside the urinary bladder. Cystoscopy proved a circular, edematous and irregular mass lesion around the urinary bladder neck. The pathological examination of TUR specimens showed a proliferative chronic cystitis. However, after about half a year, there was a recurrence of mass lesions in the urinary bladder. Moreover, right non-functional kidney and left hydronephrosis were observed. For preserving renal function, total cystoprostatectomy was performed. Nerve sparing technique for sexual function, and total bladder replacement using a detubularized sigmoid colon to obviate the need for a stoma were adopted. Postoperative course was uneventful and the function of both kidneys was recovered. Normal urination from the urethra and sexual function are both preserved. Pathological examination of the cystectomized specimen confirmed only proliferative cystitis with extensive deep ulceration and thick connective tissues. A rare case in which obstructive nephropathy was caused by proliferative cystitis is reported and discussed.

[Hyperbaric oxygen therapy in the successful treatment of two cases of radiation-induced hemorrhagic cystitis].

Hemorrhagic cystitis resulting from radiation to pelvic visceral malignant lesions often might be incurable and there have been established no definitive treatment. We experienced 2 cases with radiation-induced severe hemorrhagic cystitis refractory to conventional therapy. The treatment with hyperbaric oxygen to control hematuria was performed and obtained successful results. Gross hematuria was disappeared and cystoscopic figure was remarkably improved. No remarkable side-effect was observed in both patient. This experience suggested that hyperbaric oxygen could be considered the primary treatment for patient with radiation-induced hemorrhagic cystitis instead of usual treatment.

Clinical evaluation of commercially available urinary acidification diets in the management of idiopathic cystitis in cats.

OBJECTIVE: To compare recurrence of signs of lower urinary tract disease (LUTD) in cats with idiopathic cystitis that were fed the dry or canned formulation of a commercial diet designed to result in production of an acidic urine. DESIGN: Prospective trial. ANIMALS: 54 client-owned cats with idiopathic cystitis that was diagnosed on the basis of a history of abnormal micturition, abnormal results on urinalysis, radiography, or cystoscopy, and lack of an alternative diagnosis. PROCEDURE: Cats were assigned to be fed the canned or dry formulation of the diet. Reevaluations conducted at 2 and 16 weeks, and at 6 and 12 months included a physical examination, CBC and serum biochemical analysis (except week 2), blood gas analysis, and urinalysis. Regular telephone contacts were also made. The study was discontinued after 12 months or if signs of LUTD recurred. RESULTS: Signs of LUTD did not recur in 16 of 18 cats fed the canned diet, and 17 of 28 cats fed the dry diet (chi 2, P < 0.05). Seven cats were reevaluated at recurrence. Owners of remaining cats in which signs of LUTD recurred declined to have their pets reexamined. A different problem (bacterial urinary tract infection) was identified in only 1 cat on reevaluation. Eight cats were lost to follow-up evaluation. CLINICAL IMPLICATIONS: Feeding this commercial canned urinary acidifying diet may reduce the proportion of cats with idiopathic cystitis that will have recurrence of signs of LUTD within a 12-month period.

Potassium leak test predicts outcome in interstitial cystitis.

PURPOSE: We tested whether the potassium leak test predicts the outcome of therapy with heparinoids and antidepressants in interstitial cystitis. MATERIALS AND METHODS: We retrospectively reviewed the records of 38 evaluable patients with interstitial cystitis who underwent a potassium leak test at the initial evaluation and who were treated intravesically with heparin or oral sodium pentosan polysulfate for a minimum of 6 months. All but 1 patient were also treated with tricyclic antidepressants. Changes in average pain score during voiding, urinary frequency and nocturia were evaluated. RESULTS: The potassium leak test was positive and negative in 23 and 15 patients, respectively. There was no significant difference in the 2 groups at baseline in regard to the male-to-female ratio, patient age, years of symptoms, pain score, urinary frequency, nocturia or anesthetic capacity. After a minimum of 6 months of therapy patients in whom the potassium leak test was positive were more likely to have improvement than those in whom it was negative, as shown by a decrease of greater than 25% in pain score (78 versus 40%, p = 0.01), frequency (83 versus 47%, p = 0.02) and nocturia (83 versus 53%, p = 0.05). However, potassium leak test results showed no significant difference at the 50% decrease level in pain score, frequency or nocturia. CONCLUSIONS: The potassium leak test may predict outcome in patients with interstitial cystitis who are treated with combined heparinoid and tricyclic antidepressant medication.

[Polypoid eosinophilic cystitis mimicking bladder carcinoma].

OBJECTIVE: To report an additional case of polypoid eosinophilic cystitis mimicking a urothelial carcinoma of the urinary bladder. METHODS: An 81-year-old man presented with hematuria and dysuria that he had noted for the past month. The US findings were consistent with a bladder tumor and consequently the patient was submitted to transurethral resection. RESULTS: Histological analysis disclosed inflammatory infiltrates with numerous eosinophils (eosinophilic cystitis), but no evidence of tumor. The patient is well two years later. CONCLUSIONS: The present case demonstrates that polypoid eosinophilic cystitis can mimick a bladder carcinoma. Histopathological analysis is necessary for the differential diagnosis.
