Purpose: Nephron-sparing surgery for renal tumors in solitary kidneys has several technical difficulties and complications, including renal failure. We evaluated operative outcome and feasibility in patients with renal cell carcinoma in a solitary kidney treated with laparoscopic partial nephrectomy.
Materials and Methods: Between September 2003 and September 2008, 59 patients with renal tumors underwent laparoscopic partial nephrectomy. Among them, 4 patients with a solitary kidney were enrolled in the study. The mean age of the 2 male and 2 female patients was 66.8 years old, and their mean body mass index was 24.7. The mean size of the tumor was 3.5 cm.
Results: The mean operative time was 138.5 minutes, and estimated blood loss was 163.8 ml. In 2 patients, warm ischemic times were 25 and 55 minutes. Initiation of postoperative oral intake and ambulation were at 1.0 and 1.5 days. The mean hospital stay was 15.0 days. One patient had a complication of urinary leakage. Pathologic examination revealed renal cell carcinomas with negative surgical margins in all patients. The mean serum creatinine level of preoperative and postoperative day 1 was 1.04 and 1.73 mg/dl, respectively. One patient required temporary hemodialysis. At the mean follow-up of 21.3 months, there was no recurrence of tumors. The mean serum creatinine level at the final visit was 1.36 mg/dl.
Conclusions: Laparoscopic partial nephrectomy for renal tumors in solitary kidneys can be performed safely. Although it is a possible modality with excellent outcome, long-term follow-up for cancer control, along with advanced laparoscopic technique and experience, is necessary.
