    BACKGROUND: The aim of this study was to describe the complication profile of augmentation cystoplasty in contemporary paediatric urology as well as its effect on bladder metrics. METHODS: Consecutive operative cases were retrospectively reviewed at a single institution over 20 years (1999-2019). Short- and long-term outcomes and complications following augmentation cystoplasty were defined. RESULTS: Of the 71 operative cases; the most common underlying diagnoses were neurogenic bladder (34%), exstrophy-epispadias complex (30%) and posterior urethral valves (23%). The most common tissue-type utilized was ileal (58%) and ureteric (30%). Peri-operative urine leak affected nine (13%) children but reservoir perforations were less common (4%). Mean end-of-study detrusor pressure improved significantly following bladder augmentation (38-17 cmH2 O, P < 0.001). Bladder capacity improved significantly (67-89%, P = 0.041). The median follow-up was 4.5 years (interquartile range: 1.9-10 years). Bladder urolithiasis affected 13 (18%) patients, and symptomatic urinary tract infections 36 (51%) patients. Formation of a continent catheterisable channel contributed a number of complications relating predominantly to stenosis (50%). Repeat augmentation cystoplasty was necessary in three (4%) cases. CONCLUSION: Augmentation cystoplasty is a surgical intervention that improves bladder metrics. Given the potential complications, careful patient selection and appropriate pre-operative counselling are essential. Furthermore, pro-active post-operative management and transitional care are vital in the surgical care of children following augmentation cystoplasty.
