Other anatomic abnormalities predisposing to UTI include urethral valves (a congenital obstructive abnormality), delayed bladder neck maturation, bladder diverticulum, and urethral duplications (see Overview of Congenital Genitourinary Anomalies Overview of Congenital Genitourinary Anomalies Congenital anatomic anomalies of the genitourinary tract are more common than those of any other organ system. VUR can also be acquired in patients with a flaccid bladder due to spinal cord injury or after urinary tract surgery. VUR is usually caused by a congenital defect that results in incompetence of the ureterovesical valve. read more (VUR), which is present in 30 to 45% of young children with symptomatic UTI Urinary Tract Infection (UTI) in Children Urinary tract infection (UTI) is defined by ≥ 5 × 104 colonies/mL in a catheterized urine specimen or, in older children, by repeated voided specimens with ≥ 105 colonies/mL. A common consequence of anatomic abnormality is vesicoureteral reflux Vesicoureteral Reflux (VUR) Vesicoureteral reflux is retrograde passage of urine from the bladder back into the ureter and sometimes also into the renal collecting system, depending on severity. PathophysiologyĪnatomic, structural, and functional abnormalities are risk factors for UTI. The incidence of UTI increases in patients > 50 years, but the female:male ratio decreases because of the increasing frequency of prostate enlargement and instrumentation in men. read more or prostatitis Prostatitis Prostatitis refers to a disparate group of prostate disorders that manifests with a combination of predominantly irritative or obstructive urinary symptoms and perineal pain. Symptoms may be absent or include urinary frequency, urgency, dysuria, lower abdominal pain. In men of the same age, most UTIs are urethritis Urethritis Bacterial urinary tract infections (UTIs) can involve the urethra, prostate, bladder, or kidneys.
