Supratrigonal cystectomy and augmentation cystoplasty with ileum or ileocecum in the treatment of ulcerative interstitial cystitis/bladder pain syndrome: a 14-year follow-up.

INTRODUCTION AND HYPOTHESIS: This study analyzes the long-term results of supratrigonal cystectomy and augmentation cystoplasty in patients with severe ulcerative interstitial cystitis/bladder pain syndrome (IC/BPS) and reduced bladder capacity. METHODS: Outcome data were retrospectively and prospectively collected and analyzed in women who underwent supratrigonal cystectomy and augmentation cystoplasty for ulcerative IC/BPS at Muenster University Hospital between 1991 and 2006. We used cross-tabulation and Pearson's Chi-squared test to examine how outcome is influenced by age, preoperative functional bladder volume, and choice of augmentation material. RESULTS: After a median 171-month follow-up, analysis could be done in 26 of 27 patients. Persistent pain necessitated early revision in 2 patients (7.7%). Mean postoperative O'Leary Sant IC Score was 12.7 in the prospectively questioned patients. Responses to Patient Global Impression of Improvement (PGI-I) were: "very much better" in 15 cases (65.2%) and "much better" in 7 (30.4%). Twelve patients (52.2%) emptied their augmented bladder voluntarily, whereas 7 (32%) needed intermittent self-catheterization (ISC). The rate of patients requiring ISC tended to be lower when detubularized ileocecal bowel was used. All 5 patients (19.2%) with late relapse of ulcerative IC/BPS needed ISC. CONCLUSIONS: Severe ulcerative IC/BPS can be curatively treated in some patients by supratrigonal cystectomy and augmentation, which is associated with a high satisfaction rate and few long-term complications even over a very long follow-up. In our analysis, the need for ISC is a risk factor for late relapse, although ileocecal augmentation could increase the proportion of patients with sufficient voluntary micturition.

Comparison of deep phenotyping features of UCPPS with and without Hunner lesion: A MAPP-II Research Network Study.

OBJECTIVE: To use the phenotyping data from the MAPP-II Symptom Patterns Study (SPS) to compare the systemic features between urologic chronic pelvic pain syndrome (UCPPS) with Hunner lesion (HL) versus those without HL. METHODS: We performed chart review on 385 women and 193 men with UCPPS who enrolled in the MAPP-II SPS. 223 had cystoscopy and documentation of HL status. Among them, 12.5% had HL and 87.5% did not. RESULTS: UCPPS participants with HL were older, had increased nocturia, higher Interstitial Cystitis Symptom and Problem Indexes, and were more likely to report "painful urgency" compared with those without HL. On the other hand, UCPPS without HL reported more intense nonurologic pain, greater distribution of pain outside the pelvis, greater numbers of comorbid chronic overlapping pain conditions, higher fibromyalgia-like symptoms, and greater pain centralization, and were more likely to have migraine headache than those with HL. UCPPS without HL also had higher anxiety, perceived stress, and pain catastrophizing than those with HL. There were no differences in sex distribution, UCPPS symptom duration, intensity of urologic pain, distribution of genital pain, pelvic floor tenderness on pelvic examination, quality of life, depression, pain characteristics (nociceptive pain vs. neuropathic pain), mechanical hypersensitivity in the suprapubic area during quantitative sensory testing, and 3-year longitudinal pain outcome and urinary outcome between the two groups. CONCLUSIONS: UCPPS with HL displayed more bladder-centric symptom profiles, while UCPPS without HL displayed symptoms suggesting a more systemic pain syndrome. The MAPP-II SPS phenotyping data showed that Hunner lesion is a distinct phenotype from non-Hunner lesion.

MicroRNA-495 alleviates ulcerative interstitial cystitis via inactivating the JAK-STAT signaling pathway by inhibiting JAK3.

INTRODUCTION AND HYPOTHESIS: As a notable chronic disorder, the incidence of interstitial cystitis (IC) has been documented to have increased among the female population with activity in microRNA-495 (miR-495) implicated in this disease. The current study was aimed at elucidating the effects associated with miR-495 on the inflammatory response and bladder fibrosis in rats with ulcerative IC via the JAK-STAT pathway by targeting JAK3. METHODS: Ulcerative IC rat models were established. The targeting relationship between JAK3 and miR-495 was evaluated using luciferase reporter assay. After gain- or loss-of-function assays, mast-cell infiltration was assessed using toluidine blue staining, bladder fibrosis using Masson staining, and NO content using nitrate reductase method. JAK3 protein expression was detected by immunohistochemistry, JAK3, STAT1, STAT3, TGFß-1, Col-I, Col-III, JAK1, JAK2, p-STAT1, and p-STAT3 expression by RT-qPCR and Western blot analysis, and serum IL-6, IL-8, IL-10, IL-17, and TNF-α levels in rats by ELISA. RESULTS: Following transfection of overexpressed miR-495 or siRNA-JAK3, a diminished degree of mast-cell infiltration, number of mast cells, bladder fibrosis, NO content, JAK3-positive expression, mRNA expression of JAK3, STAT1, STAT3, TGFß-1, Col-I, Col-III, protein expression of JAK1, JAK2, JAK3, p-STAT1, p-STAT3, and expression of IL-6, IL-8, IL-10, IL-17, and TNF-α were identified. CONCLUSIONS: Collectively, our key findings provide evidence supporting the notion that the overexpression of miR-495 ameliorates inflammatory response and bladder fibrosis in ulcerative IC rat models via inactivation of the JAK-STAT signaling pathway by inhibiting JAK3.

Presenting an atlas of Hunner lesions in interstitial cystitis which can be identified with office cystoscopy.

AIM: To assist clinicians in proper visual diagnosis of Hunner lesions by providing an atlas of representative images of the variability in Hunner lesion appearance. METHODS: Available cystoscopic images of Hunner lesions were reviewed from patients with interstitial cystitis or bladder pain syndrome (IC/BPS) treated by a single clinician between 2011 and 2020. For most patients, initial cystoscopy was performed in the office under local anesthesia. Images were categorized by variations in appearance. Data including Hunner lesion descriptions and patient demographics were retrospectively collected from the medical record. Only patients who had images available, received triamcinolone injection and/or fulguration of Hunner lesions, and reported improvement of their symptoms following treatment were included in the atlas. RESULTS: Thirty-one IC/BPS patients with Hunner lesions had cystoscopic images available for review. We created an atlas of representative images. Variations in appearance include classic lesions with or without a central coagulum, inflamed lesions, non-inflamed lesions, groupings of lesions, and lesions with a red waterfall bleeding appearance. CONCLUSION: There is variation in cystoscopic appearance of Hunner lesions. Most Hunner lesions can be identified during office visits using flexible cystoscopy and local anesthesia without hydrodistention or general anesthesia. Proper visual diagnosis of Hunner lesions is of upmost importance as these patients with IC/BPS respond greatly to endoscopic intervention. This atlas will serve as a reference for clinicians and researchers, so they are able to better identify and manage these patients.

Comparison of urologic and non-urologic presentation in interstitial cystitis/bladder pain syndrome patients with and without Hunner lesions.

AIMS: To compare severity and characteristics of urologic pain, other urinary symptoms, sexual pain, psychosocial health, and the distribution and intensity of non-urologic pain between men and women with and without Hunner lesions. METHODS: All cystoscopies were performed and documented by the same clinician to ensure uniform recognition of Hunner lesions. Intensity of urologic and sexual pain, nocturia, frequency, urgency, and bladder hypersensitivity features were assessed using validated questionnaires and numeric rating scales. The distribution and intensity of non-urologic pain was assessed using self-reported history, a body map diagram, and numeric rating scales. Somatic symptom burden, depression, and anxiety were compared. RESULTS: Among the 150 participants, 27% (n = 41) had Hunner lesions (36% of men, 25% of women). Participants with Hunner lesions were significantly older (median age 58 vs 41, P < 0.001). They reported less intense urologic pain (5 vs 7, P = 0.024) and more nocturia (ICSI nocturia symptom score: 4 vs 3, P = 0.007). They also were less likely to have a history of irritable bowel syndrome (15% vs 36%, P = 0.013) and anxiety attacks (22% vs 44%, P = 0.013). Close to half of Hunner IC patients had non-urologic pain outside the pelvis. There were no differences in bladder hypersensitivity features (eg, painful bladder filling) between the two groups. CONCLUSIONS: Hunner lesions can be identified in both men and women. There are significant overlaps in terms of their urologic and non-urologic presentation. Further investigation is needed on phenotypic and biological distinction between IC/BPS with and without Hunner lesions.

Ulcerative interstitial cystitis in an adolescent successfully treated with complete transurethral ulcer resection: A case report.

INTRODUCTION: Interstitial cystitis is difficult to treat and may affect adolescents. CASE PRESENTATION: A 15-year-old girl presented with severe pain upon terminal micturition that persisted for approximately 2 hours. The pain had been present for more than 1 month. Cystoscopy revealed severe erosion throughout the trigone. Transurethral fulguration did not improve her symptoms. However, complete electric resection of the ulcer markedly reduced the symptom. After complete resection, pain on urination disappeared and she has had no pain without medication for 15 months. CONCLUSION: Complete resection not fulguration of the ulcer is effective for interstitial cystitis in adolescent female patients.
