BACKGROUND: Spontaneous urinary collecting system rupture is caused by increased ureteral intraluminal pressure secondary to an obstruction. Rarely, a small stone exerts high intraureteral pressure especially if it is located distally. Many management modalities with good outcomes have been implicated.
PURPOSE: Herein, we present a case of nontraumatic rupture of the renal calyx due to a 4 mm obstructing stone at the vesicoureteral junction.
BASIC PROCEDURES: CT scan of abdomen and pelvis without contrast, CT scan of the abdomen and pelvis with intravenous contrast, Cystoscopy, Double-J ureter stent, Urinary Foley catheter.
MAIN FINDINGS: The diagnosis was confirmed by CT imaging. Non-contrast enhanced CT scan of abdomen and pelvis showed obstructive calculi measuring 4 mm in the right vesicoureteral junction. Contrast-enhanced CT scan revealed leakage of contrast in the perinephric space at the right major calyx with intact bilateral ureters, suggestive of calyceal rupture. The treatment involved antibiotics and double-J stenting.
PRINCIPAL CONCLUSIONS: This case demonstrates that spontaneous calyceal rupture should be suspected in urolothiasis patients presenting for a severe pain even if the calculus is small (less than 5 mm) and the laboratory markers are normal. An immediate management is required to relief symptoms and prevent further complications.
