Total laparoscopic nerve-sparing radical parametrectomy for occult early-stage cervical cancer: surgical technique and postoperative bladder function.

Surgery and radiotherapy are both regarded as standard treatments for occult cervical cancers. Surgery has several theoretical advantages over radiotherapy; therefore, such cancers, especially in their early stages, are commonly treated with radical parametrectomy. However, postoperative bladder dysfunction is an important potential complication of this type of surgery. This is a case report of total laparoscopic nerve-sparing radical parametrectomy for an occult cervical cancer using our original surgical concept based on detailed anatomical investigation of pelvic nerve networks in a fresh cadaver. We evaluated the validity of our nerve-sparing technique by assessing postoperative bladder function using urodynamic studies.
