- Objectives To evaluate the long-term outcome after reconstructive surgery in patients with bladder pain syndrome/interstitial cystitis subdivided into subtypes. Methods A total of 47 patients, fulfilling the National Institutes of Health/National Institute of Arthritis, Diabetes, Digestive and Kidney Diseases criteria, were evaluated retrospectively. They all had undergone reconstructive surgery during the 25-year period of 1978 to 2003. The surgical procedures included noncontinent ureteroenterocutaneostomy (12 patients), supratrigonal cystectomy and ileocystoplasty (23 patients), continent urinary diversion (Kock pouch; 10 patients), continent orthotopic diversion (1 patient), and cecocystoplasty (1 patient). The series comprised 34 patients with classic Hunner type disease and 13 patients with nonulcer bladder pain syndrome/interstitial cystitis. The patients were preoperatively assessed by interview, visual analog pain scale, micturition diaries, urinalysis, intravenous urography, urethrocystoscopy, and bladder distension during anesthesia, including biopsy and, in selected cases, urodynamic evaluation. The data were obtained by surveying the clinical records. Results For 28 of the 34 patients with classic Hunner-type disease, the initial surgical procedure resulted in complete symptom resolution. Of the remaining 6 patients, 4 were successfully treated with a supplementary diversion procedure, cystectomy, or transurethral ulcer resection in the trigonal remnant. In contrast, only 3 of the 13 patients with nonulcer disease experienced symptom resolution after reconstructive surgery, and 2 of these required a supravesical diversion procedure. Conclusions Reconstructive surgery for refractory bladder pain syndrome/interstitial cystitis is an appropriate last resort only for patients with end-stage Hunner’s disease. The decision to embark on major reconstructive surgery in patients with bladder pain syndrome/interstitial cystitis should be preceded by a thorough preoperative evaluation, with emphasis on assessment to determine the relevant subtype (ie, classic or nonulcer disease).

- BACKGROUND: The aetiology of bladder pain syndrome (BPS) remains poorly understood, and a number of pathogenic mechanisms have been proposed. The importance of genetic factors for BPS is receiving growing attention, but data so far are of a preliminary nature. OBJECTIVE: To empirically assess the genetic and environmental contribution to BPS in a population-based sample of twins. DESIGN, SETTING, AND PARTICIPANTS: The study included >25 000 twins born between 1959 and 1985. Individuals with BPS were identified using latent class cluster analysis (LCCA) based on self-reported symptoms from a nationwide screening for complex diseases in the Swedish Twin Registry. By comparing monozygotic and dizygotic twins, we estimated twin similarity and the relative proportions of phenotypic variance resulting from genetic and environmental factors. MEASUREMENTS: Twin similarity was measured. RESULTS AND LIMITATIONS: The LCCA yielded an overall BPS prevalence of 1.1% and 2.4% for males and females, respectively. In males, the contribution of genetic effects to BPS could not be assessed because of the small number of concordant twin pairs. In women, twin similarity estimates indicated a genetic component for the aetiology of BPS, but genetic factors contributed less than one-third of the total variation in susceptibility to BPS. Nonshared environmental factors accounted for more than two-thirds of the variance, whereas early nongenetic factors shared within the family were of little or no consequence to the risk of developing BPS later in life. Use of self-reported symptoms to define the disease phenotype is a limitation of the study. CONCLUSIONS: The influence of environmental factors in the development of BPS in women is substantial, whereas genetic influences are of only modest importance for the possibility of developing the disease.

- Abstract Objective. In severe cases of stress urinary incontinence (SUI), with sphincter dysfunction, the artificial urinary sphincter AMS 800™ may be the last solution. The purpose of this study was to evaluate the outcome of surgical intervention for SUI with the AMS 800 in patients who were treated at Sahlgrenska University Hospital, Gothenburg. The primary aim of the study was to determine the complications related to the operation. Material and methods. A retrospective follow-up was done by reviewing medical records. The material comprised 97 men, who underwent their first AMS 800 implantation between May 1997 and June 2010 at Sahlgrenska University Hospital. Results. The revision rate was 28%, including an infection rate of 3% and an erosion rate of 7%. The mean follow-up for revised patients was 3 years. The median time until revision was 1 year. Seventy-five per cent of all patients were satisfied with the operation at 6 months' follow-up. Radical prostatectomy was the reason behind incontinence in 84% of patients in this series. Conclusion. The results clearly demonstrate a need for revision procedures in a considerable proportion of patients implanted with an AMS 800 device. Patient satisfaction was high, but although this operation has extremely low mortality it has its complications and the system will need to be replaced in time.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Bladder pain syndrome/interstitial cystitis (BPS/IC) is a distressing, chronic bladder disorder comprising symptoms of pain, pressure or discomfort perceived to be related to the bladder which is diagnosed primarily in women and of unknown aetiology, the diagnosis to be set after exclusion of many possible different confusable diseases. This debilitating condition was first identified in the nineteenth century, but it was not until 100 years later that an official definition, constructed by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), became accepted. However, this definition has been debated because around 60 % of patients who were clinically diagnosed with interstitial cystitis (IC) were excluded when applying the NIDDK criteria. A further fundamental problem is that treatment requirements differ importantly between BPS/IC phenotypes. So far, the majority of available studies did not take important distinctions into account, limiting the utility of clinical research in BPS.

- Objective: The aim of this study was to investigate whether protein expression of the extracellular matrix-degrading protease ADAMTS5 can be demonstrated in the urinary bladder of healthy rats, and, if so, to determine the localization of this enzyme. Materials and methods: The experiments were conducted with eight inbred male Sprague-Dawley rats. Immunohistochemistry was used to investigate the expression of ADAMTS5 in the urinary bladder. Negative controls were established by either excluding the primary antibody or applying the antibody after it had been preabsorbed with its immunogenic peptide. Confocal microscopy was used to visualize the distribution of ADAMTS5 in the urinary bladder tissue. Results: Immunoreactivity for ADAMTS5 was demonstrated in the urothelium and in the detrusor. This expression was localized not only in the cytoplasm, but also in the nuclei. Confocal microscopy corroborated these findings. Conclusion: Expression of ADAMTS5 was demonstrated in the cytoplasm as well as in the nuclei of the urothelium and detrusor cells, suggesting that it may play a role at the transcriptional level.

- Abstract Objective. The aim of this retrospective study was to review what kinds of surgical procedures are most frequently complicated by urovaginal fistulae, to find out how they were diagnosed and managed, and to study the outcome after surgical reconstruction. Material and methods. Nineteen women who underwent fistula repair at Sahlgrenska University Hospital between 2003 and 2009 were retrospectively studied by reviewing the medical records. Results. For 17 of the 19 patients hysterectomy was the causative procedure. Fourteen patients developed vesicovaginal and five developed ureterovaginal fistula. Urethrocystoscopy was sufficient for the diagnosis in nearly 50% of the patients and when combined with methylene blue instillation 90% of all fistulae were found. Several patients sought medical advice due to vaginal leakage following gynaecological surgery without the doctor suspecting a fistula, and for these patients the diagnosis was delayed. Eighteen patients were operated on with an abdominal approach and one with a vaginal approach, in all cases a minimum of 3 months after primary surgery. The reconstruction technique included the interposition of vascularized tissue. None of the patients reported leakage or relapse at follow-up after fistula repair. Conclusions. Hysterectomy was the most common cause behind the formation of urovaginal fistulae. Misinterpretation of symptoms after gynaecological surgery was common even in cases where the symptoms were indicative of a urovaginal fistula. Delayed fistula repair after a minimum of 3 months, via the abdominal route and with the interposition of vascularized tissue, yielded an excellent final outcome.
