Objective This case is reported to introduce an advanced surgical technique and share our experience with surgeons. Methods A 53-year-old man was admitted to the Department of Urology of The Second Xiangya Hospital with complaints of frequent urination and dysuria in June 2018. He had been diagnosed with genitourinary tuberculosis and left renal dysfunction at another hospital and had undergone left nephrectomy 6 months previously. At our institution, intravenous urography showed a normally functioning right solitary kidney. Computed tomography indicated a high-density mass in the abdominal cavity. At the patient’s request, robot-assisted laparoscopic augmentation ileocystoplasty and excision of the intraperitoneal mass was performed. Results The surgery was performed using a completely intracorporeal technique. The procedure was completed in 240 minutes, and the patient was discharged on postoperative day 11. At the 2-month follow-up, ultrasound examination showed that the maximal bladder capacity had increased to 1000 mL. Intravenous urography revealed no urine leakage, and filling of the bladder was satisfactory. Conclusions With the development of robot-assisted surgery, robotic surgery can be successfully used for less frequently performed operations.
