Study Type – Therapy (case series) Level of Evidence 4 What’s known on the subject? and What does the study add? A lot of information has been gathered on the subject of complications following urinary bladder augmentation and/or substitution in the recent years. The present study, based on the analysis of 86 patients, gives a critical analysis of these complications (stone formation, bowel obstruction, hematuria‐dysuria syndrome, small bowel bacterial overgrowth, persistent vesico‐ureteral reflux, obstruction at the site of ureteral reimplantation, reservoir perforation, premalignant histological changes, decreased bladder capacity/compliance requiring reaugmentation, etc.). The study adds one more new complication (small bowel colonization following colocystoplasty performed with the cecum and ascending colon) and reports complications in a fairly big (by European standards) cohort of patients with a long follow‐up. 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.

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.

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.

A case of primary ileo-psoas abscess in a neonate is presented. Psoas abscess is extremely uncommon in this age group. The role of ultrasound and computed tomography in the diagnosis is demonstrated, and the need for antibiotic therapy is emphasized for a minimum period of 2 weeks.

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.

Aims To validate the Child-Oral Impact on Daily Performance (Child-OIDP) in the Hungarian language and to explore the oral health-related quality of life (OHRQoL) and associated factors among Hungarian children with cleft lip or/and palate (CLP). Methods This cross-sectional study consists of a survey and clinical examination among conveniently selected children with CLP visiting the Pécs cleft lip and palate clinic, Pécs, Hungary. OHRQoL was assessed using the Hungarian version of Child-OIDP. Additionally, a validated structural questionnaire was used for gathering information related to oral hygiene practice. Clinical examination was done to register the dental status using ICDAS criteria, consequences of untreated dental caries (pufa), and bleeding on probing. Results were presented as proportions, means, and standard deviations (SD). Construct validity and internal reliability of the Hungarian Child-OIDP was assessed using the Pearson and Spearman's correlation coefficients, respectively. The logistic regression model examined the association between OHRQoL and explanatory variables. Results A total of 45 children with CLP participated in this study. The Hungarian Child-OIDP had the Cronbach's alpha value 0.73, and the Spearman's correlation coefficient was 0.31. The mean (SD) Child-OIDP score among the study participants was 4.4 (7.0) and three-fifths (65.9%, n = 27) of the participants reported impact in one or more items of the OHRQoL scale. Tooth brushing was more frequent among 6−10-year-olds compared to 11−16-year-olds. The proportion of those requiring restorative treatment need (DS ≥ 1) was 90.2% (n = 37), those with PUFA/pufa (score ≥ 1) was 24.4% (n = 10), and those with bleeding on probing (> 15%) was 63.4% (n = 26). Children aged 11-16 years had a higher impact on OHRQoL compared to the younger ones. Girls had a higher impact on OHRQoL compared to boys. Children with clefts involving both lip and palate had poorer OHRQoL than the rest. The same was true for those having a high dental caries rate. Conclusion The Hungarian Child-OIDP was a reliable and valid measure. There was a substantial impact on OHRQoL among Hungarian children and adolescents with CLP. Age, gender, cleft type and dental caries were associated with poor OHRQoL.
