Abstract:
Frequency of cancer in the urinary organs was significantly lower in patients with macroscopic hematuria associated with bacteriuria compared to those without bacteriuria. The predictive value of macroscopic hematuria was <1% in patients ≤ 75 years of age with concomitant bacteriuria. CT-urography added no diagnostic value over and above cystoscopy in patients with macroscopic hematuria with bacteriuria.Bacteriuria with other bacteria than E. coli or S. saprophyticus was associated with findings of bladder tumors.

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...
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...
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...
