Robot assisted laparoscopic partial nephrectomy: initial experience.

PURPOSE: Advances in laparoscopy have made laparoscopic partial nephrectomy a technically feasible procedure but it remains challenging to even experienced laparoscopists. We hypothesized that robotic assisted laparoscopic partial nephrectomy may make this procedure more efficacious than the standard laparoscopic approach. MATERIALS AND METHODS: Ten patients with a mean age of 58 years and mean tumor size of 2.0 cm underwent robotic assisted laparoscopic partial nephrectomy and another 10 with a mean age of 61 years and mean tumor size of 2.18 cm underwent laparoscopic partial nephrectomy, as performed by a team of 2 surgeons (MS and ST) between May 2002 and January 2004. Demographic data, intraoperative parameters and postoperative data were compared between the 2 groups. RESULTS: There were no significant differences in patient demographics between the 2 groups. Intraoperative data and postoperative outcomes were statistically similar. In the 10 patients who underwent robotic assisted laparoscopic partial nephrectomy there were 2 intraoperative complications. There was 1 conversion in the laparoscopic partial nephrectomy group. CONCLUSIONS: Robotic assisted laparoscopic partial nephrectomy is a safe and feasible procedure in patients with small exophytic masses. The robotic approach to laparoscopic partial nephrectomy does not offer any clinical advantage over conventional laparoscopic nephrectomy.

Multifocal renal oncocytoma in a patient with Von Hippel-Lindau mutation.

Von Hippel-Lindau disease (VHL) is a rare genetic disease with a lifetime risk of clear cell renal cell carcinoma in approximately 70% of cases. We present a case of a 63-year-old man with bilateral, multifocal renal masses. Genetic testing results were consistent with a VHL deletion. The patient had no other disease manifestations consistent with VHL. The patient underwent staged bilateral nephron-sparing procedures. Pathology of all renal masses revealed oncocytoma. To our knowledge, we describe the first reported case of multiple renal oncocytomas in a male patient with a germline VHL mutation.

Isolated renal vein thrombosis after blunt trauma.

Renal vein thrombosis typically occurs in the setting of nephrotic syndrome, tumor thrombus, primary retroperitoneal processes with vein compression, oral contraceptive use, steroid therapy, transplanted kidney, or trauma. Trauma-induced renal vein thrombosis usually presents in combination with renal arterial or parenchymal injury. We report a case of isolated renal vein thrombosis secondary to blunt abdominal and flank trauma. The diagnosis was made with computed tomography, which revealed a filling defect in the affected renal vein and persistent nephrogram on delayed images. In general, conservative management is the preferred treatment approach with anticoagulation.
