“…Regarding the renal pelvis rupture after the obstruction of the urinary tract, the lithiasis is responsible for most of the cases described in the literature. It was registered in 505 of the cases, followed by intravenous urography, pregnancy, prostatic hyperplasia, neoplasm and aortic aneurysm [7].…”

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.

“…2 Other causes of ureteral obstruction that might result in rupture are abdominal or pelvic masses, strictures, congenital abnormalities, retroperitoneal fibrosis, and connective tissue disorders. 12,13 Perforation may occur at all levels, but usually does at the upper ureter, leading to serious complications, such as urinoma, abscess formation, urosepsis, infection, and irreversible renal impairment.…”

In vitro study of age-related changes in human ureteral failure properties according to region, direction, and layer

Knowledge of the capacity of the ureteral wall to withstand urodynamic or external stresses is essential to understand ureteral injury and rupture that mostly occur following trauma, but may also be secondary to obstructive uropathy. It has clinical significance as well in the prevention of iatrogenic injury, for example, during ureteroscopy, but no information is available with regard to the age-related failure properties and regional differences have not been systematically described. Uniaxial tensile testing was performed on 166 ureteral rings and strips from 21 humans free of overt urologic disease; histological evaluation was performed. The degree of layer participation to the intact wall failure stress (=tissue strength), peak elastic modulus (=stiffness), and failure stretch (=extensibility) was assessed by examining layer-specific ruptures in the stress–stretch data. Failure stress at and peak elastic modulus before the first (muscle/adventitial) rupture correlated inversely less with age ( p < 0.05 in few regions/directions) than failure stress at the second (mucosal) rupture ( p < 0.05 in the middle and lower ureter), consistent with the decreased mucosal thickness in ≥50-year-old subjects. Failure stretch at both ruptures did not correlate with age ( p > 0.05 in most regions/directions), paralleling elastin content. Correlations with age were more significant in females than males. Failure stress at the second rupture point was higher ( p < 0.05) distally in <50-year-old but not in ≥50-year-old subjects, justified by the increased collagen distally in the former. Directional differences in failure stretches ( p < 0.05 at all ages/regions/genders) were justified by preferentially axial collagen reinforcement. The presented results may establish the foundation for computational models of iatrogenic/accidental ureteral trauma.

“…Calculi represent the most frequent cause of ureteral and pelvis rupture in the nontraumatic group. Other causes of collecting system obstruction that may lead to rupture are congenital abnormalities, abdominal or pelvic masses, retroperitoneal fibrosis, iatrogenic or postirradiation strictures, transplanted kidney, and connective tissue disorders [2–4]. …”

Rupture of the urinary collecting system associated with perinephric or retroperitoneal extravasation of the urine is an unusual condition and it is commonly associated with renal obstructing disease. Perforation could occur at any level from the calix to the bladder but it is usually seen at the fornices and upper ureter. It may lead to several serious consequences including urinoma, abscess formation, urosepsis, infection, and subsequent irreversible renal impairment. We report a case of a 69-year-old woman who presented at the emergency department of our institution with severe abdominal pain. Due to symptomatology worsening, complete laboratory evaluation was performed and the patient underwent abdominal contrast enhanced computed tomography (CT) evaluation which showed contrast agent extravasation outside the excretory system without any evidence of renal calculi at basal acquisition. It was decided to perform a double-J stent placement which was followed by complete healing of the ureter and its removal was performed 8 weeks later. Diagnosis and therapeutic approaches are discussed.
