The goal of this observational study is to analyse the occurence of urinary calculi after bladder augmentation in children: * location of the calculi (kidney or bladder) * type of bladder augmentation with higher rate of urinary calculi and why * Find risk factors of urinary calculi in bladder augmentation (age, sex, other bladder procedures..)
Study the data of patients younger than 18 years old, who underwent a bladder augmentation, complicated by urinary calculi.

Rate of participants with urinary calculi
Rate of participants with urinary calculi After bladder augmentation
Time frame: Through study completion, an average of 2 years
Location of urinary calculi in the participants
After bladder augmentation, urinary calculi can be seen on postoperative imaging such as abdominal ultrasound, CT scan, and MRI. The different locations of these calculi can be the kidneys, the ureters, the bladder, or the urethra. Each patient who has had urinary calculi will be reported, and the location of the calculi will be specified depending on the imaging results.
Time frame: Through study completion, an average of 2 years
Time frame between surgery and occurence of urinary calculi in the participants After bladder augmentation
Time frame between surgery and occurence of urinary calculi in the participants After bladder augmentation
Time frame: Through study completion, an average of 2 years
Management of urinary calculi after bladder augmentation in the participants
3 main procedures help getting rid off urinary calculi: extracorporeal lithotripsy, endoscopic surgery or laparotomy. The patients were divided depending on the procedure that was used to remove the urinary calculi.
