History Taking in Pediatric Renal System Cases
Introduction to Pediatric Renal History Taking
Taking a comprehensive history in pediatric renal cases is crucial for accurate diagnosis and effective management. It requires a systematic approach tailored to the child's age and developmental stage. The history should be obtained from both the child (when appropriate) and the caregiver, focusing on specific renal symptoms, overall health, and developmental milestones.
Key points to remember:
- Use age-appropriate language and techniques
- Establish rapport with both the child and caregiver
- Be patient and allow time for clear communication
- Pay attention to nonverbal cues from the child
- Validate concerns and address any anxieties
Chief Complaint
The chief complaint is the primary reason for seeking medical attention. In pediatric renal cases, common chief complaints include:
- Changes in urination patterns (frequency, volume, color)
- Pain or discomfort during urination
- Abdominal or flank pain
- Swelling (edema) in face, hands, or feet
- Fever
- Fatigue or weakness
- Poor growth or failure to thrive
It's important to document the chief complaint in the patient's or caregiver's own words, noting the duration and any associated symptoms.
History of Present Illness
The history of present illness (HPI) provides a detailed account of the current problem. For pediatric renal cases, focus on:
- Onset and progression of symptoms
- Urinary symptoms:
- Frequency and volume of urination
- Color, odor, and clarity of urine
- Presence of blood in urine (hematuria)
- Pain or burning during urination (dysuria)
- Urgency or incontinence
- Pain:
- Location, severity, and character
- Factors that worsen or alleviate the pain
- Swelling (edema):
- Location and extent
- Timing (morning vs. evening)
- Fever: pattern, duration, and associated symptoms
- Changes in appetite or weight
- Fatigue or decreased energy levels
- Recent illnesses or exposures
- Treatments attempted and their effects
Remember to use the OPQRST (Onset, Provocation/Palliation, Quality, Region/Radiation, Severity, Timing) approach when applicable to gather comprehensive information about symptoms.
Past Medical History
A thorough past medical history is essential in pediatric renal cases. Include:
- Prenatal and birth history:
- Maternal infections or medications during pregnancy
- Gestational age and birth weight
- Complications during delivery
- Prenatal ultrasound findings (e.g., hydronephrosis)
- Previous renal or urinary tract conditions:
- Urinary tract infections (UTIs)
- Vesicoureteral reflux (VUR)
- Congenital anomalies of the kidney and urinary tract (CAKUT)
- Other medical conditions:
- Diabetes
- Hypertension
- Autoimmune disorders
- Heart conditions
- Surgical history, especially urological procedures
- Medications (current and past):
- Prescription drugs
- Over-the-counter medications
- Herbal supplements
- Allergies (medication and environmental)
- Immunization status
- Growth and development milestones
Family History
Family history is crucial in identifying genetic predispositions to renal diseases. Inquire about:
- Kidney diseases in first-degree relatives:
- Polycystic kidney disease
- Alport syndrome
- Focal segmental glomerulosclerosis (FSGS)
- History of recurrent UTIs or VUR in family members
- Congenital anomalies of the kidney and urinary tract
- Hereditary conditions that may affect the kidneys:
- Diabetes
- Hypertension
- Autoimmune disorders
- Family history of dialysis or kidney transplantation
- Consanguinity (marriage between close relatives)
Consider creating a three-generation pedigree to visualize the family history and identify patterns of inheritance.
Social History
Social history provides context for the child's overall health and potential environmental factors affecting renal health. Include:
- Living situation:
- Home environment (urban, rural, access to clean water)
- Family structure and primary caregivers
- School or daycare attendance
- Dietary habits:
- Fluid intake
- Salt consumption
- Special diets or restrictions
- Physical activity and sports participation
- Exposure to second-hand smoke
- Travel history (relevant for certain infections)
- Psychosocial factors:
- Stress at home or school
- Support systems
- In adolescents, consider asking about:
- Smoking, alcohol, or drug use
- Sexual activity (relevant for STIs that can affect the urinary system)
Developmental History
Developmental history is particularly important in pediatric cases, as renal problems can affect growth and development. Include:
- Growth parameters:
- Height and weight percentiles
- Head circumference (in infants)
- Developmental milestones:
- Motor skills
- Language development
- Social skills
- Cognitive abilities
- Toilet training history:
- Age of initiation and completion
- Any regressions or difficulties
- Puberty onset and progression (in adolescents)
- School performance and any learning difficulties
- Behavioral concerns
Note any delays or regressions in development, as these can be indicators of systemic effects of renal disease.
Review of Systems
A comprehensive review of systems helps identify symptoms that may be related to renal disease or other organ systems. Focus on:
- General: fever, fatigue, weight changes
- Skin: rashes, bruising, pallor
- HEENT: eye puffiness, vision changes, throat infections
- Respiratory: shortness of breath, cough
- Cardiovascular: chest pain, palpitations
- Gastrointestinal: nausea, vomiting, abdominal pain, diarrhea
- Genitourinary: changes in urine output, color, or smell; genital discharge or pain
- Musculoskeletal: joint pain or swelling, muscle weakness
- Neurological: headaches, seizures, changes in mental status
- Endocrine: excessive thirst, changes in hair growth
- Hematologic: easy bruising or bleeding, pallor
- Psychiatric: mood changes, anxiety
Pay special attention to symptoms that may indicate systemic manifestations of renal disease or potential complications.

- Location:
- Where is the swelling noticed? (face, hands, feet, abdomen, genitals)
- Is it symmetrical or unilateral?
- Onset and progression:
- When was the swelling first noticed?

- Presence of nausea, vomiting, or diarrhea
- Any abdominal pain or discomfort
- Urinary symptoms:
- Changes in urination patterns
- Excessive thirst or fluid intake
- Energy levels and activity:
