Soft tissue tumors of the lower genitourinary tract in children require a multidisciplinary treatment. The international CWS-91 and CWS-96 protocols established the second-look operation as a control procedure. One of the surgical options is a total cystectomy followed by the subsequent genitourinary reconstruction. The article presents a short characteristic of the reconstructive method modo Studer, advantages connected with this procedure, possible complications as well as description of three clinical cases of children treated from 1994 to 2001 in the Department of Hematology and Pediatric Oncology in Wrocław. All patients were qualified as the clinical stage III and treated with primary chemotherapy and/or radiotherapy, followed by total cystectomy and subsequent genitourinary reconstruction modo Studer. This procedure led in all cases to the complete remission, which is present up to date. The regular clinical and diagnostic controls as well as the patients' compliance enable the immediate detection of any possible complication as well as the nearly unchanged life activity.
