[Partial nephrectomy by selective renal parenchymal clamping using a new clamp].

Area of Science:

• Urology
• Surgical Innovation

Context:

• Open partial nephrectomy is a standard procedure for kidney tumors.
• Selective renal parenchymal clamping is an alternative to pedicle clamping.
• The Réniclamp is a novel device designed for renal parenchyma clamping.

Purpose:

• To evaluate the efficacy and safety of the Réniclamp in open partial nephrectomy.
• To assess the outcomes of using selective renal parenchymal clamping with the Réniclamp.

Summary:

• 37 patients underwent partial nephrectomy using the Réniclamp.
• Mean operating time was 147 minutes, mean clamping time was 25 minutes.
• No clamp slippage or parenchymal damage occurred; surgical margins were negative.

Impact:

• The Réniclamp provides a viable alternative to pedicle clamping for most renal tumors.
• Homogeneous pressure distribution by the Réniclamp prevents parenchymal damage and bleeding.
• This technique is suitable for imperative and elective partial nephrectomies.
