Abstract
PURPOSE To evaluate the urodynamic changes in patients who have undergone colocystoplasty (CCP), gastrocystoplasty (GCP) and ileocystoplasty (ICP) in a retrospective study. Changes in urinary continence, incidence of pathologic contractions before and after augmentation, alterations of urodynamic parameters were also examined. METHODS Eighty-four patients were included in the study who underwent bladder augmentation between 1987 and 2017. Group I: 35 patients with CCP. Group II: 18 patients with GCP. Group III: 31 patients with ICP. Cystometry was performed at 3, 6, and every 12 months, then biannually after augmentation. Pre- and postoperative urodynamic changes were analysed statistically. RESULTS In Group I, two patients and in Group III, one patient remained incontinent after CCP and ICP. Bladder capacity increased significantly, maximal intra-vesical pressure decreased and compliance improved in all groups (p < 0.001). Postoperative studies showed pathologic contractions in the augmented bladder in half of the patients with GCP, in 43% of patients after CCP and 26% of patients with ICP. CONCLUSION From the urodynamic point of view, ileum is the most adequate option in the long term. Contractions after augmentation might be caused by the remaining peristalsis of the detubularised segment. Further investigations are needed to evaluate pathologic contractions that remained after detubularisation.

Abstract
Objectives: To look at the changing role of cystoplasty in the neuropathic population.Design: Retrospective case series.Setting: Single center over a 10-year period from 2004 to 2014.Participants and intervention: In 1995, the Princess Royal spinal injuries unit published the outcomes of 78 neuropathic patients who had undergone cystoplasty in the 10-year period from 1982 to 1992. [Singh G, Thomas DG. Enterocystoplasty in the neuropathic bladder. Neurourol Urodyn 1995; 14(1): 5-10.]. In this series, we review 51 consecutive patients undergoing the same operation over a 10-year period from 2004 to 2014 in the same single unit.Outcome measures: Demographic data were collected to include patient age, condition, and previous treatments. Pre- and post-operative details included sphincter insertions, renal function, continence rates, and complications.Results: Despite an increase in the number of patients seen at the unit, there were considerably fewer cystoplasty procedures performed in the current series (51 vs. 78 in the 1982-1992 series). There were also significantly fewer patients with spina bifida and fewer concomitant sphincter insertions in the latter series (eight patients vs. 52 in the 82/92 series). Nevertheless, similar outcomes are observed between the current and 1982-1992 series, with continence rates of 93.7 and 93.6%, respectively and low numbers of reported adverse events for both retrospective cohorts.Conclusions: Cystoplasty remains a safe and effective option for the management of neuropathic bladder in a carefully selected group of patients.

Abstract
Our study hypothesis is that the interline registered pH of the cow reticulum can be used as an indicator of health and reproductive status. The main objective of this study was to examine the relationship of pH, using the indicators of the automatic milking system (AMS), with some parameters of cow blood components. The following four main groups were used to classify cow health status: 15-30 d postpartum, 1-34 d after insemination, 35 d after insemination (not pregnant), and 35 d (pregnant). Using the reticulum pH assay, the animals were categorized as pH < 6.22 (5.3% of cows), pH 6.22-6.42 (42.1% of cows), pH 2.6-6.62 (21.1% of cows), and pH > 6.62 (10.5% of cows). Using milking robots, milk yield, fat protein, lactose level, somatic cell count, and electron conductivity were registered. Other parameters assessed included the temperature and pH of the contents of reticulorumens. Assessment of the aforementioned parameters was done using specific smaX-tec boluses. Blood gas parameters were assessed using a blood gas analyzer (EPOC (Siemens Healthcare GmbH, Erlangen, Germany). The study findings indicated that pregnant cows have a higher pH during insemination than that of non-pregnant ones. It was also noted that cows with a low fat/protein ratio, lactose level, and high SCC had low reticulorumen pH. They also had the lowest blood pH. It was also noted that, with the increase of reticulorumen pH, there was an increased level of blood potassium, a high hematocrit, and low sodium and carbon dioxide saturation.

Abstract
Patients with neurologic disease commonly develop overactive bladder (OAB) symptoms of urgency, frequency, and/or urge incontinence that remain bothersome despite oral pharmacologic therapy. Management of refractory OAB in the neurogenic population is a complex issue with no uniform treatment strategy. When treatment fails or patients generally are dissatisfied with the adverse effects of oral therapy, available options include sacral neuromodulation, percutaneous tibial nerve stimulation (PTNS), botulinum toxin injections, and lower urinary tract reconstruction such as augmentation cystoplasty. A thorough knowledge and understanding of available and emerging treatment options for neurogenic detrusor overactivity is paramount to assisting clinicians in choosing an appropriate treatment. This article reviews the non-pharmacologic treatment options for neurogenic OAB, mainly botulinum toxin, neuromodulation, and lower urinary tract reconstruction, and discusses important relevant studies.

Abstract
PURPOSE Radical cystectomy and urinary diversion may cause chronic metabolic acidosis, leading to long-term bone loss in patients with bladder cancer. However, the risk of fractures after radical cystectomy has not been defined. We assessed whether radical cystectomy and intestinal urinary diversion are associated with increased risk of fracture. PATIENTS AND METHODS Population-based study using SEER-Medicare-linked data from 2000 through 2007 for patients with stage 0-III bladder cancer. We evaluated the association between radical cystectomy and risk of fracture at any site, controlling for patient and disease characteristics. RESULTS The cohort included 50,520 patients, of whom 4,878 had cystectomy and urinary diversion. The incidence of fracture in the cystectomy group was 6.55 fractures per 100 person-years, compared with 6.39 fractures per 100 person-years in those without cystectomy. Cystectomy was associated with a 21% greater risk of fracture (adjusted hazard ratio, 1.21; 95% CI, 1.10 to 1.32) compared with no cystectomy, controlling for patient and disease characteristics. There was no evidence of an interaction between radical cystectomy and age, sex, comorbidity score, or cancer stage. CONCLUSION Patients with bladder cancer who have radical cystectomy and urinary diversion are at increased risk of fracture.

Abstract
Augmentation cystoplasty and urinary diversion are no longer commonplace in the management of patients with neurogenic bladder, but remain an important surgical treatment for those with refractory LUTS who have failed neuromodulation and onabotulinum toxin treatment or who are not candidates for those treatments. Augmentation is an option in patients who can perform intermittent catheterization and is usually performed with ileum or large intestine. Some patients benefit from continent cutaneous catherizable channels. Supravesical urinary diversion may be necessary in more severe cases. Ileovesicostomies are being supplanted by indwelling suprapubic catheters, and when catheters fail conduits may be a better option. When feasible, the diverted bladder should be excised to avoid pyocystis.

Abstract
Background and Aims: Introduction of intestinal tissue in the urinary tract results in numerous metabolic changes. This study investigates the effects of augmentation sigmoid colocystoplasty on the physical growth and bone mineralization in bladder exstrophy patients. Materials and Methods: Physical growth, serum biochemistry and bone mineral density were assessed pre and post augmentation in 34 of 54 patients who were treated by staged sigmoid colocystoplasty for classical bladder exstrophy during the period 1985–2007. Physical growth was determined by comparing the height and weight for age with standard growth charts. Serum biochemistry included calcium, phosphate and alkaline phosphatase levels. Bone mineral density (BMD) was determined at the femoral head using the dual energy X-ray absorptiometry (DEXA) scan at 15 ± 4.5 months after the augmentation. The DEXA scan findings were compared with 22 normal Indian children who served as controls and 18 unaugmented patients with bladder exstrophy. In 13 augmented patients, the DEXA scan could be repeated after an interval of six months. Results: The mean percentile height and weight were comparable in the pre and post-augmentation period with no statistically significant difference (P=0.135 for height and P=0.232 for weight). Biochemical parameters of bone metabolism also did not show any statistically significant changes after colocystoplasty. The BMD was 0.665 ± 0.062 g/cm2 in the controls and 0.612 ± 0.10 g/cm2 in the unaugmented bladder exstrophy patients. In the augmented patients, the BMD was 0.645 ± 0.175 g/cm2 and six months later it was 0.657 ± 0.158 g/cm2. These differences were not statistically significant. Conclusions: In our study, no significant effects on the physical growth and bone mineral metabolism were observed in exstrophy bladder patients following sigmoid colocystoplasty.

Abstract
OBJECTIVE • To evaluate complications after urinary bladder augmentation or substitution in a prospective study in children. PATIENTS AND METHODS • Data of 86 patients who underwent urinary bladder augmentation (80 patients) or substitution (6 patients) between 1988 and 2008 at the authors' institute were analysed. • Ileocystoplasty occurred in 32, colocystoplasty in 30 and gastrocystoplasty in 18. Urinary bladder substitution using the large bowel was performed in six patients. • All patients empty their bladder by intermittent clean catheterization (ICC), 30 patients via their native urethra and 56 patients through continent abdominal stoma. Mean follow-up was 8.6 years. • Rate of complications and frequency of surgical interventions were statistically analysed (two samples t-test for proportions) according to the type of gastrointestinal part used. RESULTS • In all, 30 patients had no complications. In 56 patients, there were a total of 105 complications (39 bladder stones, 16 stoma complications, 11 bowel obstructions, 5 reservoir perforations, 7 VUR recurrences, 1 ureteral obstruction, 4 vesico-urethral fistulae, 4 orchido-epididymitis, 4 haematuria-dysuria syndrome, 3 decreased bladder capacity/compliance, 3 pre-malignant histological changes, 1 small bowel bacterial overgrowth and 7 miscellaneous). • In 25 patients, more than one complication occurred and required 91 subsequent surgical interventions. Patients with colocystoplasty had significantly more complications (P < 0.05), especially more stone formation rate (P < 0.001) and required more post- operative interventions (P < 0.05) than patients with gastrocystoplasty and ileocystoplasty. CONCLUSIONS • Urinary bladder augmentation or substitution is associated with a large number of complications, particularly after colocystoplasty. • Careful patient selection, adequate preoperative information and life-long follow-up are essential for reduction, early detection and management of surgical and metabolic complications in patients with bladder augmentation or substitution.

Abstract
PURPOSE Bladder augmentation and substitution has been assumed to improve health-related quality of life in patients with urinary incontinence. This study was performed to elicit an evidence base for or against the above hypothesis. METHODS Between 1988 and 2006, 67 bladder augmentations and 7 bladder substitutions were performed at our institute. Inclusion criteria for the cross-sectional study were a postoperative period of more than 1 year and an age of at least 10 years at the time of operation. A multimodality treatment-specific questionnaire (comprising 38 questions) was designed and sent to 61 patients. Quality of life was investigated in all patients and between the groups of patients with meningomyelocele (Group A) versus bladder exstrophy (Group B), patients, who are catheterizing themselves via urethra (Group C) versus stoma (Group D) and patients who are using (Group E) versus not using wheelchair (Group F) following the surgery. For the statistical analysis Students t test, Wilcoxon signed rank test and correlation analysis were used. RESULTS A significant overall improvement was found in patients quality of life following this surgery (P < 0.05). Ninety percent of patients would prefer again bladder augmentation or substitution to their previous state. Patients with meningomyelocele are changing pads or diapers more frequently than exstrophy patients because of their bowel problems postoperatively. Quality of life improved better in patients performing CIC via stoma than in patients who perform it via their native urethra (P < 0.05). Outcomes were independent of patients age and of the post-augmentation time to assessment (P < 0.05). CONCLUSIONS Bladder augmentation or substitution significantly improved the health-related quality of life in children and young adolescents taking part in the study. The authors are planning a prospective long-term follow-up of the patients (longitudinal study) to validate the results.

Abstract
AIMS The type of bladder augmentation on pre-existing vesicoureteral reflux (VUR) was assessed. The effects of urodynamic changes on the resolution of VUR following augmentation cystoplasty performed with various gastrointestinal segments were examined. It was queried whether elimination of high-pressure bladder is sufficient to resolve pre-existing reflux. METHODS A retrospective record review of patients who underwent bladder augmentation between 1987 and 2004. Patients were divided into two groups. Group I included patients who had a simultaneous augmentation and ureteral reimplantation. Group II included patients with reflux in whom only a bladder augmentation was performed. Pre-and post-augmentation urodynamic results were compared in both groups. The outcome of VUR and the role of various gastrointestinal (GI) segments on the resolution of VUR were studied. RESULTS Sixty-three patients underwent bladder augmentation during the study period. Twenty-six of them had VUR before augmentation. There were 10 patients in Group I and 16 patients in Group II. In Group I, VUR ceased in all patients, while in group II, VUR resolved in 14 patients and persisted in two patients. Small and large bowel segments used for augmentation had no effect on the resolution of VUR but the results of gastrocystoplasties were less favorable. Urodynamically there was no significant difference between the various augmentation cystoplasties. CONCLUSIONS Bladder augmentation alone without simultaneous antireflux repair is usually sufficient for the resolution of pre-existing reflux. The various GI segments used for augmentation have no effect on urodynamic results and the resolution of VUR.

Abstract
We evaluated the bone mineral density (BMD) after ileal augmentation cystoplasty in a group of children with and without myelomeningocele. Between 1996 and 2003, eight patients with neurogenic bladder and seven patients with non-neurogenic bladder underwent augmentation ileocystoplasty. Preoperative and postoperative serum creatinine and electrolytes were measured. All patients underwent clinical evaluation, supine height measurement, blood gas analysis, and BMD measurement using a dual energy X-ray absorptiometry (DEXA) postoperatively. BMD was measured at L1-L4 and femoral neck, and compared to age- and sex-matched population. Follow-up time was calculated from the day of surgery to the day of DEXA performance. A total of eight boys and seven girls with the mean age of 10.2 +/- 4.1 years were evaluated with respect to BMD measurement. Mean age was 9.8 years in neurogenic group and 10.5 in non-neurogenic group. Mean follow-up was 728 and 616 days in neurogenic and non-neurogenic groups, respectively. There were no significant differences between ages, follow-up times, preoperative and postoperative creatinine levels, pH and bicarbonate values, and supine heights. Mean BMD at L1-L4 was 55.7% in neurogenic group and 83.8% in non-neurogenic group. There was a statistically significant difference between the two groups (P = 0.02). Mean BMD at femoral neck was 72% in neurogenic group and 86.2% in non-neurogenic group. The difference was also statistically significant (P = 0.028). After augmentation ileocystoplasty, the BMD in early postoperative period of patients with myelomeningocele is lower than the patients with non-neurogenic neurogenic bladder, which have the same clinical characteristics except the neurologic pathology. In the light of our findings and the reported literature data as well, we may claim that BMD decrease after augmentation ileocystoplasty depends more on the underlying neurologic pathology and its locomotor consequences rather than the enterocystoplasty itself.

Abstract
PURPOSE We summarize important metabolic consequences and long-term complications associated with enterocystoplasty with particular emphasis on the pediatric patient with genitourinary abnormalities. MATERIALS AND METHODS A directed MEDLINE literature review for metabolic and long-term complications following enterocystoplasty was performed. Information gained through the published literature and from our database was reviewed and summarized to provide the reader with a thorough review of the subject. RESULTS Bowel is not a perfect tissue for substitution or augmentation and its use to treat functionally and structurally compromised bladders is associated with several metabolic consequences and long-term complications. Metabolic acidosis is the most common metabolic abnormality seen. The rates and severity of these complications vary, although they may have a profound impact on patient quality of life after enterocystoplasty. CONCLUSIONS The metabolic consequences and long-term complications associated with enterocystoplasty are important clinical features of this intervention. Careful consideration should be given to them prior to pursuing enterocystoplasty.

Abstract
The interposition of bowel in continuity with the urinary tract has allowed for the preservation of renal function and continence in children with bladder exstrophy, as well as neurogenic and valve bladders. Although bladder augmentation with ileum or colon has been shown to be safe, the long-term effects of metabolic acidosis in addition to abnormalities in linear growth and bone metabolism remain largely unknown. We reviewed the literature to critically examine linear growth in children who have had bladder augmentation with a particular emphasis on the correlation between acid-base status, bone mineralization and growth. The majority of studies suggest that linear growth is not affected by bladder augmentation. In the short-term, children post-augmentation have varying degrees of metabolic acidosis which, overtime, appears to resolve with no affect on linear growth. In a single study, bladder augmentation led to significant bone demineralization almost a decade after surgery, however, even in these children no decrease in linear growth was noted. No alterations in bone density levels were seen with short-term follow-up.
