Nerve-sparing radical hysterectomy: A pilot study

Nerve-sparing radical hysterectomy has increasingly been used for cervical cancer, with less morbidity. We aimed with this study: i) to describe an alternative technique of nerve-sparing radical Piver III hysterectomy, using the CUSA(R), in which attention was given to the uterosacral ligament and cardinal ligament; ii) to evaluate the feasibility of this new nerve-sparing technique; iii) to describe the surgical anatomy of the autonomic nervous system; iv) to assess the early incidence of bladder dysfunction. Twelve consecutive patients with local-regional advanced cervical cancer were enrolled in the study on nerve-sparing radical hysterectomy with extended pelvic lymphadenectomy. The mean age was 44 years (range, 30-59), mean body mass index was 24 kg/m(2) (range, 18-30), mean operating time was 217 mins (range, 195-240), and mean blood loss was 437 cc (range, 200-750). The average hospitalization time was 9 days (range, 5-15 days). Two patients presented pathologically positive parametrium. Two of 12 (17%) patients were discharged with self-catheterism. In the first outpatient follow-up, 1 patient had recovered spontaneous voiding. The nerve-sparing technique with CUSA(R) can be an option to reduce radical hysterectomy-related morbidity. The technique proved to be feasible, with promising results in terms of preventing bladder dysfunction. An elevated body mass index and large tumors can impair the performance of the technique. Further studies clarifying neuroanatomy and neurophysiology of autonomic nervous structures, as well as a prospective controlled trial on nerve-sparing radical hysterectomy should be carried out to confirm our data.
