Step 1: Understanding the Question:
Phimosis is the inability to retract the foreskin over the glans penis. It can be physiological in infants but becomes pathological (true phimosis) if it persists and causes symptoms. Step 2: Detailed Explanation:
Physiological vs. Pathological: Most boys are born with a non-retractable foreskin. By age 3, about 90% of boys should be able to retract it. If it remains tight and causes problems, it is considered true phimosis.
Ballooning of Foreskin: This is a classic clinical sign of phimosis. During micturition, the urine gets trapped between the glans and the tight foreskin before exiting through the narrow orifice, causing the foreskin to "balloon" out.
Symptoms: Painful urination (dysuria), recurrent infections (balanoposthitis), and ballooning are the primary complaints.
Balanitis Xerotica Obliterans (BXO): This is a chronic inflammatory skin condition (lichen sclerosus of the penis) that causes a white, scarring ring at the tip of the foreskin. It is the most common cause of acquired pathological phimosis.
Management: Initial treatment may include topical steroid creams. If symptoms persist or if BXO is present, circumcision is the definitive surgical treatment.
Step 3: Final Answer:
The classic symptom of "ballooning" during urination in a young boy is indicative of True Phimosis.
