    Abstract:
    BACKGROUND AND PURPOSE: Because of the explosion of laparoscopy in urology coinciding with the excellent results of open nephron-sparing surgery (NSS) for small renal masses, laparoscopic NSS has become an alternative to an open surgical approach. We report our results with laparoscopic NSS in patients who have had a minimum of 1 year of follow-up. PATIENTS AND METHODS: All consecutive laparoscopic partial nephrectomies from November 1998 through February 2002 were assessed. The mean patient age, body mass index, and American Society of Anesthesiology score were 57.1 years, 28.5 cm/kg2, and 2.0, respectively. The procedures were performed using hand-assisted (N = 28) or standard (N = 12) laparoscopic techniques. Hospital records were reviewed in order to obtain operative, perioperative, and follow-up data. RESULTS: The median operating room time, estimated blood loss, and hospital stay were 184 minutes, 300 mL, and 2.0 days, respectively. No patients were converted to an open surgical procedure. Four patients (10%) required a blood transfusion, and one (2.5%) had a postoperative urinoma. The mean tumor size was 2.3 cm. Twenty-nine lesions were renal-cell carcinoma, and 11 were benign. With a mean CT scan follow-up of 100.0 weeks, there has not been any recurrence of renal-cell carcinoma. CONCLUSION: Laparoscopic NSS can be performed with acceptable complication rates, which will continue to decrease as newer methods of controlling hemostasis are developed. Although follow-up is fairly short, no renal-cell carcinoma recurrences have appeared. At this point in time, the oncologic efficacy of a laparoscopic approach appears to mirror that of the open surgical technique.
