Urinary Calculi After Bladder Augmentation in Children

Study Overview
=================
Brief Summary
-----------------
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..)

Detailed Description
-----------------
Study the data of patients younger than 18 years old, who underwent a bladder augmentation, complicated by urinary calculi.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Rate of participants with urinary calculi | After bladder augmentation | 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. | Through study completion, an average of 2 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time frame between surgery and occurence of urinary calculi in the participants | After bladder augmentation | 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. | Through study completion, an average of 2 years | 
| Risk factors of urinary calculi after bladder augmentation in the participants | Age, sex, type of bladder augmentation... | Through study completion, an average of 2 years |
