The introduction and popularization of laparoscopic cholecystectomy has been accompanied with a considerable increase in perforation of gallbladder during this procedure (10%--32%), with the occurrence of intraperitoneal bile spillage and the consequent increase in the incidence of lost gallstones (0.2%--20%). Recently the complications associated with these stones have been documented in the literature. We report a rare complication occurring in an 81-year-old woman who underwent laparoscopic cholecystectomy and developed cutaneous fistula to the umbilicus and elimination of biliary stones through the urinary tract. During the cholecystectomy, the gall bladder was perforated, and bile and gallstones were spilled into the peritoneal cavity. Two months after the initial procedure there was exteriorization of fistula through the umbilicus, with intermittent elimination of biliary stones. After eleven months, acute urinary retention occurred due to biliary stones in the bladder, which were removed by cystoscopy. We conclude that efforts should be concentrated on avoiding the spillage of stones during the surgery, and that no rules exist for indicating a laparotomy simply to retrieve these lost gallstones.Com a introdução e popularização da colecistectomia por via laparoscópica houve um aumento considerável na taxa de perfuração da vesícula biliar durante o procedimento, determinando o derramamento de bile na cavidade peritoneal e consequente aumento da incidência de cálculos biliares perdidos na cavidade. Recentemente, as complicações associadas com estes cálculos vêm sendo estabelecidas na literatura. Os autores relatam uma complicação rara ocorrida em uma paciente de 81 anos que foi submetida à colecistectomia laparoscópica e apresentou no pós-operatório uma fístula cutânea para a cicatriz umbilical e eliminação de cálculos biliares pelo trato urinário. Concluímos que é importante evitar o derramamento de cálculos durante a cirurgia, porém a laparotomia não deve ser indicada simplesmente para retirada de cálculos perdidos durante a colecistectomia laparoscópica
