   "title": "Etiology",
   "content": "Causes of urethritis include infection, trauma, chemical irritation, and foreign body. Infectious urethritis is uncommon in prepubertal children; in sexually active adolescents and adults, sexually transmitted infections are the major cause. When infectious urethritis is suspected, a urethral smear and urine culture should be included in the laboratory evaluation. Chemical irritation (from soaps, bubble baths, or other topical exposures) and mechanical trauma are more typical causes in young, prepubertal children who are not sexually active.\n"

  {
   "title": "Related Structural Conditions",
   "content": "Urethral strictures can be congenital (rare) or acquired, the latter occurring after instrumentation, trauma, or an inflammatory process that produces an exudate followed by secondary sclerosis. Affected children present with dysuria, infection, or a weak urinary stream; diagnosis is made by voiding cystourethrogram or cystoscopy. Urethral prolapse is the complete protrusion of the urethral mucosa beyond the meatus, occurring in girls; although rare in the general population, it is associated with young age, Black or Hispanic ethnicity, and low socioeconomic status, though the underlying cause is unclear. Patients present with dysuria, gross hematuria, or blood spotting on the underwear. Meatal stenosis with meatitis is a related consideration, particularly in boys.\n"

   "title": "Clinical Features",
   "content": "Urethritis presents with dysuria accompanied by urethral discharge or blood spotting on the child's underwear. Acute urinary retention in infants and children is usually voluntary and can be associated with severe acute cystitis, urethritis, meatitis (in boys), or vaginitis; severe constipation can also cause urinary retention. In boys with urinary retention, urethral stricture (congenital or traumatic) and meatal stenosis with meatitis should be considered; urethral valves are more likely to cause dysuria or straining than complete retention. In girls, urinary retention is unlikely to result even from severe labial adhesions, so an uncommon lesion such as a prolapsed ureterocele should be considered instead.\n"

  {
   "title": "Diagnostics",
   "content": "Evaluation of dysuria in prepubertal children follows an algorithmic approach that considers urethritis alongside cystitis, pyelonephritis, and other structural or irritant causes. Suspected infectious urethritis warrants a urethral smear and urine culture. All children younger than 2 years, and boys of any age presenting with urinary tract symptoms, should be evaluated for congenital anatomic abnormalities such as vesicoureteral reflux. Across the urinary tract broadly, E. coli is the predominant pathogen (accounting for roughly 75-90% of infections, reflecting its status as the predominant periurethral flora), with Klebsiella, Enterobacter, Proteus, Citrobacter, Staphylococcus saprophyticus, and Enterococcus also implicated; Proteus and Pseudomonas infections tend to occur following obstruction or prior instrumentation.\n"
  },
  {
   "title": "Treatment",
   "content": "Management depends on the underlying cause. Urethral prolapse is treated with sitz baths, antibiotics, topical estrogen creams, or surgical repair when needed; left untreated, prolapsed mucosa can become necrotic. Urethral strictures are managed according to findings on voiding cystourethrogram or cystoscopy, potentially requiring urologic intervention. Infectious urethritis from an identified pathogen is treated with targeted antimicrobial therapy, and in adolescents, treatment follows standard sexually transmitted infection protocols when an STI is the cause.\n"

  {
   "title": "Complications",
   "content": "Untreated urethral prolapse can progress to necrosis of the prolapsed mucosa. Acquired urethral strictures can progress to obstruct urinary flow, presenting with a weak stream or recurrent infection if not addressed. As with other urinary tract infections, unrecognized or inadequately treated infectious urethritis in the context of an underlying anatomic or functional abnormality (such as vesicoureteral reflux) can contribute to ascending infection and renal involvement.\n"

   "title": "Evaluating Dysuria with Discharge or Blood Spotting",
   "content": "In a child presenting with dysuria accompanied by urethral discharge or blood spotting on the underwear, distinguish urethritis from cystitis and pyelonephritis using the broader UTI evaluation framework, and obtain a urethral smear and urine culture when infectious urethritis is suspected. In a prepubertal, non-sexually-active child, favor chemical irritation, trauma, or a foreign body over infection as the likely cause, since infectious urethritis is uncommon at this age; in a sexually active adolescent, prioritize STI testing, since sexually transmitted infections are the major cause of urethritis in this group. Examine girls specifically for urethral prolapse when gross hematuria or blood spotting is the presenting complaint, particularly in young girls of Black or Hispanic ethnicity from lower socioeconomic backgrounds, and start with sitz baths, antibiotics, or topical estrogen before considering surgical repair, since untreated prolapse can progress to mucosal necrosis.\n"

   "title": "Working Up Weak Stream, Retention, or Recurrent Symptoms",
   "content": "In a boy with a weak urinary stream or recurrent urinary symptoms, evaluate for urethral stricture (congenital or acquired, the latter from instrumentation, trauma, or prior inflammation) and meatal stenosis with meatitis, using voiding cystourethrogram or cystoscopy to confirm structural pathology. Consider urethral valves in a boy with dysuria or straining, recognizing that these more typically cause obstructive voiding symptoms than complete urinary retention. When retention occurs in a child, first consider it to be voluntary, often related to pain from severe cystitis, urethritis, meatitis, or vaginitis, or from severe constipation, before pursuing more invasive imaging; in girls, avoid attributing retention to labial adhesions alone and consider a rarer structural cause such as prolapsed ureterocele instead. Apply universal screening for anatomic abnormalities such as vesicoureteral reflux in every child under 2 years and every boy of any age who presents with urinary tract symptoms, given the higher prevalence of underlying congenital anomalies in these groups.\n"
