Here, we aimed to present a rare case of spontaneous calyceal rupture secondary to a proximal ureteric stricture in a patient with no clinical history of renal stones. Establishing an early diagnosis is crucial to avoid several serious complications such as urinoma, abscess formation, urosepsis, and renal impairment. The diagnosis can be easily made using computed tomography when contrast extravasations are seen on the delayed excretory phase, which confirms the rupture. The diagnosis is often delayed as it is rarely seen in daily practice, in addition to the non-specific symptoms and clinical presentation. Obstruction increases ureteric intraluminal pressure with subsequent forniceal or calyceal rupture and urine extravasations into the perirenal space and retro-peritoneum. Other reported rare etiologies include benign or malignant extrinsic ureteric compression, pregnancy, posterior urethral valve, pelvic-ureteric junction obstruction, and vascular extrinsic compression, iatrogenic and intravenous fluid administration. An obstructive ureteric calculus is considered the most common cause. The most frequent obstructive causes include ureteric calculi, stricture, or tumor. Non-traumatic calyceal rupture is also known as spontaneous calyceal rupture and is an unusual complication of obstructive uropathy that is much more common than the traumatic subtype. It can occur anywhere along the urinary tract however, the commonest site is at the renal calyces. Rupture of the collecting system can be due to traumatic or non-traumatic causes. Kidney, Calyceal rupture, Computed tomography, Radiology, Urography Herein, we report a case of spontaneous renal calyceal rupture secondary to ureteric stricture. ![]() Contrast-enhanced computed tomography usually confirms the diagnosis when contrast extravasations are seen in the excretory phase. The diagnosis is often delayed due to fact that it is rarely seen in daily practice and patients exhibit non-specific symptomatology at the time of presentation. Rupture of the urinary collecting system is an unusual condition caused by a variety of causes, with obstructive ureteric calculi being the most common cause.
