The authors discuss a masochistic young woman addicted to surgery, whose enuresis began nineteen months after the death of her mother. Subsequent battles over the enuresis with the aunt, who took her mother's place, made bladder control the issue through which to express hostility and invite retaliation. Besides having enuresis, bladder infections, and surgical traumas to the bladder, the patient was later found to have developed interstitial cystitis.
