Q1: Why couldn't surgeons simply pull the knotted cable out through the penis?
A1: Pulling a knotted object out through the narrow urethral channel would have caused catastrophic structural damage. The knot's diameter exceeded the width of the urethra, meaning forced traction would have torn the vascular tissues and damaged the urinary sphincter, risking permanent incontinence and severe internal hemorrhaging.
Q2: Why do flexible cords and wires knot themselves inside the bladder?
A2: The bladder is an expandable, hollow muscular container. When a long, flexible wire is fed through the narrow urethra into the open space of the bladder, the bladder's natural muscle contractions and curved interior cause the tip of the wire to loop back on itself. Any tension placed on the wire subsequently pulls the loop into a tight, irreversible knot.
Q3: What are the primary long-term risks after urethral foreign body removal?
A3: The most common long-term complication is urethral stricture, the formation of dense scar tissue inside the urethra that narrows the passage and obstructs normal urine flow. Other serious risks include recurrent urinary tract infections, urethral diverticula, and erectile dysfunction if adjacent neurovascular structures sustain trauma.
