Bladder cancer is the fourth most common tumor in men and is usually diagnosed around the seventh decade of life. The predominant histological type is transitional cell carcinoma, while squamous cell carcinomas and adenocarcinomas are less common. Spontaneous rupture of the excretory system, an obstructive complication, is a rare occurrence and even more uncommon when caused by neoplasia. The aim of this article is to report the case of a male patient with spontaneous rupture of the pelvis due to squamous cell carcinoma of the bladder. With regard to renal pelvis rupture due to primary urinary tract obstruction, stone formation (lithiasis) is the most common cause, accounting for 50%, while neoplasia ranks fifth. As for the histological subtypes of the neoplasm, it is essential to note that transitional cell carcinoma is observed in 90% of cases.
