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.

The local microbiome after pediatric bladder augmentation: intestinal segments and the native urinary bladder host similar mucosal microbiota. J Pediatr Urol 2019; 15:30.e1-30.e7. [PMID: 30206025 DOI: 10.1016/j.jpurol.2018.07.028] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2018] [Accepted: 07/26/2018] [Indexed: 01/26/2023]
Abstract
INTRODUCTION Next-generation sequencing (NGS) techniques have provided novel insights into the microbiome of the urinary bladder (UB). In children after bladder augmentation using either ileum (ileocystoplasty, ICP) or colon (colocystoplasty, CCP), the fate of the mucosal microbiome introduced into the urinary tract remains unknown. OBJECTIVE The aim was to compare the mucosal microbiome of the native UB vs the augmented intestinal segment (IS) using NGS. STUDY DESIGN Twelve children after bladder augmentation (ICP n = 6, CCP n = 6) were included. Biopsies were taken during routine postoperative cystoscopy from the native UB and the IS. Specimens underwent whole-genome DNA extraction, 16S rRNA gene amplification, NGS, and Quantitative Insights Into Microbial Ecology (QIIME) data analysis. Downstream statistical data analyses were performed in Calypso. RESULTS Patients' median age at the time of surgery was 11 years (6-17 years), and the median interval between augmentation and sampling was 7 years (4-13 years). α-Diversity (Shannon diversity index) was not significantly different between IS vs UB, ICP vs CCP, and male vs female. No general differences in the overall bacterial pattern (β-diversity) were found between IS, UB, ICP, and CCP groups. The groups overlapped in principal coordinate analysis (PCoA) and non-metric multidimensional scaling (NMDS) analysis (Figure). Age at sampling had a statistically significant influence on β-diversity at the genus level. Corynebacterium, Pseudoxanthomonas, Lactobacillus, Flavobacterium, and Micrococcus were the most dominating taxa detected over all samples. There was an obvious dominance of the genus Corynebacterium in the samples taken from the UB and IS in both ICP and CCP patients. Limitations of this study include the relatively small number of patients. CONCLUSION After bladder augmentation, the native UB and augmented ISs (ICP and CCP) host similar microbiota despite their distinct differences of originating mucosal anatomy.

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
PURPOSE Nonparasitic splenic cysts (NPSCs) are uncommon in children. The aim of this multinational and multicentric study was to present the authors' experience as well as the changing trends in the management of NPSCs over the last 25 years. MATERIAL AND METHODS From 1981 to 2005, 50 children or adolescents were surgically treated for NPSCs in 6 paediatric surgical centres in four European countries. The medical records of these 50 patients with NPSCs were reviewed retrospectively. RESULTS Twenty-six male and 24 female patients were operated on. Age at surgery ranged from 1 to 17 years (mean 11.9). Seventeen patients were symptomatic. Six total (4 open and 2 laparoscopic) and 26 partial (22 open and 4 laparoscopic) splenectomies were performed. Laparoscopic fenestration or deroofing and open cystectomy was carried out in 9 patients, respectively. Histological findings revealed the lesion to be an epidermoid cyst (n = 28), a pseudocyst (n = 15) or a mesothelial cyst (n = 2). In 5 patients haemangioma or lymphangioma was the pathological diagnosis. At a mean follow-up of 2.9 years, residual cysts were found in 8 laparoscopically treated patients, 4 of whom required re-do laparoscopy or open surgery. CONCLUSIONS Over the last two decades, the surgical treatment of NPSCs has changed from a formerly customary total splenectomy to spleen-conserving procedures, such as total cystectomy with or without partial splenectomy or partial cystectomy. These therapeutic modalities can be performed laparoscopically, if technically possible. Fenestration or deroofing of the cyst resulted in a high recurrence rate (7/9).

Abstract
UNLABELLED The aim of this paper was to review the authors' experience with cutaneous vesicostomy (CV) over the last 15 years including indications, results, and complications of CV. MATERIALS AND METHODS The records of 31 patients treated by CV between 1987 and 2002 were reviewed. There were 20 boys and 11 girls. The two main primary pathologies were neuropathic bladder (19 patients) and posterior urethral valve (PUV) (7 patients). All patients underwent a Blocksom-type operation at a mean age of 23 months (range 14 days-9 years). Pre- and postoperative conventional uromanometry was performed in 18 patients (58%) and bladder function was assessed. RESULTS In 23 patients (74%) the CV provided a successful diversion with improvement of the upper urinary tract and/or stabilization of the renal function. In 5 patients (16%) with PUV, the improvement was temporary. In 3 patients (10%) the CV did not result in an improvement. Twenty-four patients underwent CV closure after a mean duration of 23 months (range, 1 month-7 years) of diversion. In 2 patients with myelomeningocele (MMC) and severe somato-mental developmental delay, CV was not closed and is being considered as a permanent treatment option. Urodynamic studies in 5 PUV patients showed impaired compliance and high intravesical pressure following a successful valve ablation and closure of CV. In the neuropathic bladder group the bladder function improved following closure of CV and commencement of anticholinergic medication and clean intermittent catheterization (CIC). Our augmentation ratio in the neuropathic bladder group was 22%. Complications of CV included: stenosis in 7 patients (22%), prolapse in 2 (6%), and cellulitis in 2 (6%). The revision rate was 16%. CONCLUSIONS In young infants CV had a less favourable result in the PUV patients than in cases with high-pressure neuropathic bladder with upper tract dilatation and severe urinary tract infection (UTI), where CV provided decompression and prevented deterioration of the renal function. Cutaneous vesicostomy has stood the test of time in our changing paediatric urological practice and it remains a valuable weapon in the armoury of paediatric urologists in selected patients.

Abstract
Previous work performed on electron-irradiated Li2O crystals has demonstrated the simultaneous formation of two populations of colloids of metallic lithium, one is associated with oxygen bubbles and a typical size of >10 microm, while the other one consists of nanoclusters in the range of <10 nm. In the present neutron scattering investigation these small colloids are characterized in detail based on a thorough analysis of distortion scattering around Bragg peaks. It is shown that the small lithium colloids are slightly elongated precipitates with typical dimensions of around approximately 5 nm. For the large lithium colloids a well-defined orientation relation with respect to the Li2O matrix has been determined.

Abstract
OBJECTIVES To investigate whether colocystoplasty has resulted in metabolic changes in the growing child during long-term follow-up according to whether cecum with ascending or sigmoid colon was used. METHODS Twenty-eight patients (mean age at surgery 11 years) were included in the study and divided into two groups: group 1, cystoplasty with cecum and ascending colon (12 patients) and group 2, sigmoid cystoplasty (16 patients). Patients' linear growth, body mass index, and the following parameters were estimated before surgery and at 3, 6, and 12 months, and then yearly after surgery: blood and urine electrolytes (sodium, potassium, chloride, calcium, phosphorus, magnesium), creatinine, urea, blood gases, blood pH, urine pH, and blood alkaline phosphatase (ALP). All the data were statistically analyzed. RESULTS In group 1, the blood ALP increased significantly (P = 0.026) during follow-up. Severe metabolic acidosis with or without hyperchloremia was found in 7 patients. In group 2, the serum sodium and serum calcium levels decreased significantly (P = 0.014 and P = 0.003, respectively); however, the blood ALP, urine sodium, and urine phosphorus levels increased significantly (P = 0.033, P = 0.027, and P = 0.026, respectively) during follow-up. A statistically significant decrease in blood pH (P = 0.022) was found after surgery. Severe metabolic acidosis with or without hyperchloremia was detected in 5 patients. The average linear growth decreased significantly (P = 0.001 and P = 0.016, respectively) 1 and 2 years postoperatively. CONCLUSIONS The statistically significant increase in blood ALP and decrease in serum calcium indicate bone demineralization after colocystoplasty. Our investigations in children suggest that bone demineralization is more frequent after sigmoid cystoplasty than after the use of cecum and ascending colon.

Abstract
PURPOSE We conducted a prospective, long-term assessment of the histological changes that can occur following bladder augmentation with colon or stomach. MATERIALS AND METHODS Histological evaluations of biopsies from 44 consecutive patients undergoing augmentation (colocystoplasty in 26, gastrocystoplasty in 18) were performed. Patients underwent endoscopic assessment and tissue sampling at 2 or 4-year intervals following the initial augmentation procedure. Patients with less than 2 years of followup were excluded from the analysis. Specimens were taken from the native bladder, the augment segment (large bowel or stomach) and the anastomotic line. Sections (4 mu.) were examined using standard histological staining methods (hematoxylin and eosin and periodic acid-Schiff) and immunohistochemistry was performed for different markers of neoplasia, cellular proliferation and blood group antigens. Histological findings were correlated with the incidence of stone formation and urinary tract infection. RESULTS Group 1 consisted of 20 patients undergoing colocystoplasty who met the criteria for study inclusion. Of the patients 10 (50%) had stones, 19 (95%) had a positive urine culture and 6 had no histological changes. While no cases of malignancy were identified, other forms of pathological change were noted in 14 of the 20 patients (70%). Group 2 included 15 patients undergoing gastrocystoplasty who met the criteria for study inclusion. No stones or malignancy were identified in this group. Positive urine cultures were recorded in 2 patients (13%), no histological changes were found in 6 and 9 (60%) had pathological changes. CONCLUSIONS Periodic prospective biopsy evaluation of children who have undergone either colocystoplasty or gastrocystoplasty failed to reveal any histological evidence of malignancy after 10-year followup. However, histological evidence of a premalignant lesion 13 years after followup suggests that screening for premalignant lesions should be initiated no later than 6 to 10 years following enterocystoplasty.

Abstract
The most common origin of the urinary incontinence are the myelodysplasia and congenital urogenital malformations in childhood. Surgical augmentation of the urinary bladder with or without continent diversion, may be indicated in case of unsatisfactory result of all other conservative treatments. Between 1987-2000 bladder augmentation or substitution was carried out with large bowel or gastric segment in 37 patients. The age at surgery was between 6-21 yrs, (mean 12.3 yrs). The authors discuss the results of the 30 patients in whom follow up was at least 1 yr (12-113 months, mean 43 months). The urinary incontinence could be solved in 24/30 of the children, 6/30 remained in the same condition without worsening any of them. In 11/30 patients complication was not observed at all, but in 19/30 further surgeries were necessary in 30 times, mainly due to stone formation. The authors state that the augmentation cystoplasty is a useful method for the creation of a low pressure urinary reservoire which with or without a continent diversion may solve the urinary incontinence, however the patients need a lifelong follow-up due to the possible long-term risks.

Abstract
A case of von Recklinghausen's disease with double somatostatin producing neuroendocrine tumour of the ampulla and duodenum is reported. A search of the world's literature revealed 28 patients with immunohistologically proven duodenal somatostatinoma associated with type I neurofibromatosis. These tumours are seldom associated with a recognizable "somatostatin syndrome", but often present with obstructive jaundice, duodenal obstruction, weight loss or gastrointestinal bleeding. Histologically, psammoma bodies are frequently encountered in the glandular lumina of duodenal somatostatinomas (66%), whereas their presence in other neuroendocrine tumours of the gastrointestinal tract is very rare. Metastatization is rare (27%) and mainly confined to lymph nodes (88%). In the world literature duodenal somatostatinoma is associated with von Recklinghausen's disease in 50%.
