Purpose: To evaluate the efficacy and safety of laparoscopic nephrectomy.
Methods: From June 1994 to November 1999, 10 patients underwent laparoscopi
c nephrectomy at Osaka University Medical Hospital and Osaka Rosai Hospital
. Laparoscopic nephrectomy was performed either via transperitoneal or retr
operitoneal approach under general anesthesia. These 10 cases were reviewed
in respect of primary disease of the kidney, operative time, complications
and postoperative convalescence.
Results: Of the 10 patients, five were preoperatively diagnosed as having a
non-functioning kidney with hydronephrosis, two patients were diagnosed as
having an atrophic kidney, two had renal cell carcinoma and one had renal
pelvic tumor. The average operative time was 374 min (range 270-675 min). T
he mean blood loss was 330 mL (range 60-800 mL). One patient required trans
fusion due to postoperative oozing. The average hospital stay after operati
on was 7 days. No major postoperative complications were observed.
Conclusion: Laparoscopic nephrectomy is an option in surgically managing re
nal disorders, including malignancies, although it has a longer operative t
ime compared to conventional open surgery.
