Objective: To investigate the clinical features, diagnosis and treatment of spontaneous renal pelvis rupture in children.

Methods: The clinical data of one patient with spontaneous renal pelvic rupture caused by ureteral calculus were reviewed, and the common etiology, mechanism and diagnosis and treatment options were analyzed based on literature.

Result: A spontaneous rupture of the renal collecting system is a rare complication that may occur in the presence of an elevated intrapelvic pressure. This study shows one case of a patient with spontaneous pelvic rupture by the calculus in childhood. Spontaneous rupture of the renal pelvis and urinary extravasation were detected by contrast-enhanced computed tomography scan. Conservative treatment with the drainage of the posterior peritoneum using a drainage catheter and the placement of a JJ stent are generally satisfactory.

Conclusion: Performing a contrast CT scan with urography phase can save time in establishing a diagnosis and enable immediate urological intervention. The primary treatment of renal pelvic rupture consists of conservative treatment and Open surgery .The placement of a double-J ureteral stent is currently the method of choice.
