Spontaneous rupture of renal pelvis secondary to ureteral obstruction by urothelial tumor

Urothelial carcinoma of the proximal ureter revealed by spontaneous forniceal rupture: A case report

“…2 However, other causes are incriminated such as trauma, retroperitoneal fibrosis, and exceptionally malignant tumors. 1 , 2 Few cases of excretory tract rupture secondary to tumor obstruction have been reported in the literature. In our case, the spontaneous rupture of the upper urinary tract was caused by a urothelial tumor.…”

“…Spontaneous rupture of the upper urinary tract with extravasation of urine into the peri-renal space is a rare and potentially serious condition. 1 It is usually associated with ureteral obstruction by stones. 1 Other rare causes are tumors, trauma, and iatrogenic procedures.…”

“… 1 It is usually associated with ureteral obstruction by stones. 1 Other rare causes are tumors, trauma, and iatrogenic procedures. 2 We report a case of spontaneous forniceal rupture secondary to ureteral obstruction caused by urothelial tumor and discuss difficulties of diagnostic and treatment.…”

Renal pelvic rupture: A case report of an unexpected cause

“…In another series by Gershman et al, they didn't cite any case of primal urinary tract tumor, while extrinsic ureteral compressions were listed as the second cause of RPR [3] , [4] . Otherwise, only some single cases reported the causality of urinary tract tumors in RPR [1] .…”

“…In another hand, primal ureteral tumors are uncommon, representing less than 5% of all urothelial carcinomas. However, there's only a few cases reporting their involvement in a RPR [1] .…”
