Abstract:
The incidence of placenta accreta spectrum is on the rise. The most serious entity within this spectrum is percreta: extension beyond the uterus. The bladder is most commonly involved in these cases and is especially relevant for the urologist. Important sequelae include hemorrhage, massive transfusion, maternal mortality and urinary tract injury. Approaching this disorder as well as associated urinary tract involvement in a standardized and multi-disciplinary fashion significantly improves outcomes and reduces morbidity. Herein, we present a case of complete placenta percreta involving the bladder that was successfully managed with minimal obstetrical and genitourinary morbidity.

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
