OBJECTIVE: This study aims to describe the presence of bladder foreign body as a rare complication following intraprostatic ethanol injection.
CASE REPORTS: A 71-year-old man and a 70-year-old male with bladder catheter probe due to obstructive benign prostatic enlargement underwent ethanol injection via transrectal echography.
RESULTS: The first patient presented a urinary infection with acute urinary retention one year after the procedure. Ultrasonography revealed a 30 cc intravesical foreign body confirmed by urethrocystoscopy. Endoscopic treatment was unsuccessful, and the patient underwent cystotomy with retrieval of a soft, oval, brownish mass. Histological examination of the mass showed benign gland-stromal prostatic hyperplasia with extensive coagulative necrosis. The second patient had an acute urinary retention episode 3 months after surgery. The ultrasonography revealed an abnormal vesicoprostatic mass. Endoscopic treatment was successful, but required 2 sessions. Histological examination of the mass showed acute suppurative inflammation with marked autolysis of prostatic tissue. These foreign bodies in the bladder acted as a nest to promote infection, and generated a valve effect in the bladder neck, resembling a giant vesical lithiasis clinic, which was a diagnostic and therapeutic challenge since few centers worldwide manage this technique for prostatic hyperplasia.
CONCLUSIONS: To our knowledge, this is the second report of a "calculus" or "foreign body" formed by prostatic tissue in the urinary tract after the injection of ethanol.
