Introduction
Foreign bodies (FBs) of the urinary bladder are common in urological clinical practice.1,2 Most FBs in the bladder are inserted through the urethra for sexual gratification and psychological condition.1,2 FBs vary, including plastic forks, spoons, metal screws and pieces of aluminum, pieces of cardboard and paper, staplers, writing instruments, such as pens and pencils, coaxial cables, etc.1,3 This unusual sexual act of FB insertion into the urethra is known as “urethral sounding.”4,5 It is generally rarer in females than in males2 and even rarer to be inserted so deep enough into the urethra to damage the bladder.6 Herein, we report a rare case of a female who forcefully used a sharp hair stick for urethral sounding until it penetrated the bladder wall.
