From the urine routine report:
• Pus cells: 18–20 /hpf → Elevated
• RBC: 8–10 /hpf → Present
• Slightly turbid urine
• Trace protein
• Culture (not shown clearly, assuming pending/negative)
These findings are consistent with a Urinary Tract Infection (UTI).
Her initial symptoms (burning urination, pain) support this.
Now:
• Burning improved after Urispas + Nitrofurantoin (Matrifur)
• But she has nausea
• Right-sided lower abdominal tenderness
• Period delayed by 10 days
Important Considerations:
1️⃣ UTI is confirmed by urine routine
2️⃣ Right lower abdominal pain raises concern for:
• Ovarian pain
• Ovulation-related pain
• Appendicitis (if severe, worsening)
•
Kidney involvement (if flank pain, fever)
3️⃣ Delayed period (10 days)
At 16 years:
• Irregular cycles are common
• Infection and stress can delay periods
• But pregnancy should always be ruled out if sexually active
Nausea could be:
• Due to Nitrofurantoin (very common side effect)
• Due to hormonal delay
• Due to anxiety
• Rarely due to upper UTI
Next Steps
✔ 1. Check for Red Flags Immediately
Go to emergency if:
• Fever
• Vomiting
• Severe right lower abdominal pain
• Pain increasing on movement
• Back/flank pain
Because that may indicate:
• Appendicitis
• Pyelonephritis
⸻
✔ 2.
Pregnancy Test (Important if sexually active)
Even at 16, this must be clinically clarified.
Delayed period + nausea → always rule out pregnancy.
⸻
✔ 3. Continue Antibiotic Properly
If Matrifur (Nitrofurantoin) was prescribed:
• Complete full course (usually 5 days)
Take after food to reduce nausea.
⸻
✔ 4. If Right-Sided Pain Persists
Do:
• Ultrasound abdomen & pelvis
To rule out:
• Ovarian cyst
• Appendicitis
• Pelvic cause
Health Tips
✔ Increase water intake
✔ Avoid holding urine
✔ Take antibiotic after meals
✔ Avoid spicy/junk food during recovery
✔ Monitor temperature daily
✔ Track next menstrual cycle
Most likely this is a simple UTI with medication-related nausea and stress-related delayed cycle — but right lower abdominal tenderness should not be ignored if persistent.
If you can share:
• Does she have fever?
• Is the pain constant or only on pressing?
• Is urine culture report available?
I can guide you precisely whether this is routine UTI recovery or something needing urgent scan.
For a structured evaluation and to prevent complications in a young girl, I recommend booking a focused online consultation so we can review the reports properly and decide whether imaging is necessary.
