Abstract:

This article reports a case of bladder cancer，who was admitted to the Second Affiliated Hospital of Nanjing Medical University due to "painless gross hematuria over two months". The color Doppler ultrasound of the urinary system showed that patient suffered from strong echoes in bladder，bilateral kidney stones，and mild right hydronephrosis. Further computed tomography （CT） confirmed the suspicious bladder-occupying lesion. Urinary tract cytology showed that dysmorphic cells were detected in urine-based smears and did not exclude tumors. A diagnosis of bladder cancer was considered，cystoscopy was performed and confirmed to be muscle invasive bladder cancer.After clarifying the indications for surgery，improving preoperative examination，and excluding contraindications，transpneumatic bladder route robot-assisted single-port laparoscopic bladder tumor resection and transurethral flexible ureteroscopic holmium laser lithotripsy with double kidney stones were performed under general anesthesia on August 8，2023. The machince preparation time was 15 min，the robotic operation time was 34 min，the time of transurethral flexible ureteroscopic holmium laser lithotripsy with double kidney stones was 181 min and the total operation time of the patient was 230 min. The intraoperative blood loss was about 20 ml.There were no complications during the operation. The patient recovered well after surgery. The results showed that single port robot-assisted laparoscopic partial cystectomy via pneumatic bladder approach is efficient，simple，delicate，safe，and the curative effect is positive.
