Objective To summarize various treatment methods and experiences of bladder and urethral foreign bodies in children.Methods A total of 15 children with bladder and urethral foreign bodies admitted to our hospital during Aug.2015 and Feb.2024 were selected.The characteristics,clinical manifestations,surgical methods,surgical skills and postoperative recovery were analyzed.Results The patients aged 7-13(11.0±1.6)years,including 14 males and 1 female.Preoperative diagnosis was confirmed with color Doppler ultrasound and abdominal standing plain film.Emergency surgery was performed in 14 cases,and open surgery in 1 case with concurrent pyuria,whose foreign bodies were removed after 2 days of anti-infection treatment.Among the 15 children,9 had foreign bodies removed through cystoscopy,2 through cystoscopy combined with percutaneous renal puncture kit,2 through cystoscopy combined with a small incision on the pubic bone,1 through cystoscopy combined with a scrotal incision,and 1 through cystoscopy combined with a perineal incision.The average surgical time was(63.3±50.5)min,blood loss(1.9±1.9)mL,and postoperative hospitalization(5.8±3.8)days.No complications such as urinary extravasation,urinary fistula,bladder diverticulum,or urinary disorders occurred.Postoperative follow-up of 1 and 3 months showed no complications such as abnormal urination or urinary tract infections.Conclusion The onset of bladder and urethra foreign bodies in children is concealed.Once the diagnosis is confirmed,surgery should be performed as soon as possible.The surgical method should be selected based on the comprehensive evaluation of the location,size,shape,and number of foreign bodies and presence of calculi.Minimally invasive surgery can be performed in most cases.
