Robot-assisted Laparoscopic Radical Cystectomy and Sigmoid Orthotopic Neobladder Reconstruction for a Bladder Rhabdomyosarcoma Child: Case Report and Literature Review.

A six-month-old child was admitted into our center with complaint of hydronephrosis in June 2018. He was diagnosed as embryoid rhabdomyosarcoma after cystoscopy with biopsy. After 22 Gy radiotherapy and 4 cycles chemotherapy (VAC), robot-assisted radical cystectomy was performed. The orthotopic neobladder was reconstructed with sigmoid colon and bilateral ureter was reimplanted in Politano-Leadbetter technique. The patient was discharged after 14 days and chemotherapy was continued. Recent ultrasound examination showed that his maximal bladder capacity had increased to 120 mL, and intravenous urography revealed no urine leakage. The tumor is in good control and the neobladder works well.
