Renal pelvic rupture: A case report of an unexpected cause

Renal pelvic rupture (RPR) is a rare condition, that is most usually caused by obstructive calculi. In another hand, primal ureteral tumors are also uncommon, with only a few cases reporting their involvement in a RPR. We report a case with a multimodality discussion of an ureteral tumor, with a spontaneous renal pelvic rupture (RPR) forming a large retrorenal urohematoma. Only few series reported the subject of RPR in the English literature. Only some single cases reported the causality of urinary tract tumors in RPR. RPR is an imaging based diagnosis. Herein, upper urinary tract tumors show a variable appearances at imaging. By reporting this case, we highlight the role of both computed tomography (CT) and magnetic resonance (MR) imaging in the diagnosis of the RPR and their accuracy in the detection of the ureteral tumor. We also consolidate the effectiveness of the conservative attitude in the management of the RPR. •An ureteral tumor can lead to a renal pelvic rupture.•Both CT and MR imaging are accurate in the detection of the ureteral tumors.•Non-surgical management of renal pelvic ruptures is efficient.
