Function-preserving surgery for urologic cancer

Radical surgery that is intended to cure cancer disease tends to cause some damage to the operated organ and the quality of life of the patient. It is now a worldwide trend to preserve the function and minimize the operative damage to the patient, without compromising the oncological outcome. In urologic cancers, nephron-sparing surgery for kidney tumors, and nerve-sparing procedures in radical cystectomy and radical prostatectomy for retaining potency are now more frequently used for providing better quality of life after surgery. New constructive surgeries such as neobladder formation and nerve graft techniques after complete removal of the cavernous nerve have been developed for recovering the lost function.
