Laparoscopic Partial Nephrectomy.

J Endourol 2020 May;34(S1):S17-S24

The Smith Institute for Urology, Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, New Hyde Park, New York, USA.

Renal cell carcinoma has historically been managed by radical nephrectomy, but as knowledge of the disease has advanced, nephron sparing surgery has become the norm in appropriately selected tumors. Laparoscopic partial nephrectomy (LPN) has been shown to have comparable oncologic outcomes and a shorter convalescence period compared to the traditional open partial nephrectomy. Dissemination of techniques has led to significantly increased use of minimally invasive nephron sparing surgery, and LPN remains a cost-effective and efficacious method for approaching small renal masses.

Pre-operative Renal Artery Embolization in Laparoscopic Radical and Partial Nephrectomy: A Multidisciplinary Approach to Renal Tumors.

Surg Technol Int 2020 May;36:23-28

Department of Surgery, S. Andrea Hospital, La Spezia, Italy, Department of Health Sciences, Università del Piemonte Orientale, Novara, Italy.

Background: Despite being widely adopted, the laparoscopic approach to radical and partial nephrectomy is still burdened by high rates of hemorrhagic complications, which require blood transfusions and conversion to open surgery with increased morbidity. While pre-operative renal artery embolization (PRAE) can prevent intraoperative blood loss and vascular injuries, its prophylactic use is still a matter of debate. This study evaluated the safety and efficacy of PRAE in overcoming the main pitfalls of laparoscopy, which are related to the absence of tactile feedback. Read More

A three-dimensional, anatomy-based nephrometry score to guide nephron-sparing surgery for renal sinus tumors.

Cancer 2020 May;126 Suppl 9:2062-2072

Department of Urology, Chinese People's Liberation Army (PLA) General Hospital/PLA Medical School, Beijing, China.

Background: A quantitative nephrometry scoring system specifically for renal sinus tumors will assist in classifying surgical complexity and treatment planning.

Methods: By using preoperative computed tomography, magnetic resonance imaging, and 3-dimensional image reconstruction, 5 critical components were assessed: the ratio of the sinus area occupied by the tumor in relation to the whole sinus area (R), the compression of the renal segmental vessels or collection system by the tumor (O), the anteroposterior relation of the tumor relative to the segmental vessels or collection system (A), the tumor diameter (D), and whether the tumor affects a solitary kidney (S) ("ROADS"). The ROADS score, indicating low, moderate, or high surgical complexity, was then used to guide surgical strategy planning, including cooling techniques, surgical approaches, and parenchyma incision techniques.

The value of renal score in both determining surgical strategies and predicting complications for renal cell carcinoma: A systematic review and meta-analysis.

Cancer Med 2020 Apr 12. Epub 2020 Apr 12.

Department of Urology, Affiliated Zhongda Hospital of Southeast University, Nanjing, China.

Objectives: Radical nephrectomy (RN) was the standard treatment for renal cell carcinoma (RCC). However, recent studies have found that partial nephrectomy (PN) could achieve similar effects as radical nephrectomy, and has the advantages of less bleeding and shorter hospital stay. The choice of surgical strategies has become a concern of clinicians, which could be guided by renal score introduced by Kutikov et al Therefore, we conducted this meta-analysis to clarify the value of renal score of determining surgical strategies and predicting complications.

Partial nephrectomy provides equivalent oncologic outcomes and better renal function preservation than radical nephrectomy for pathological T3a renal cell carcinoma: A meta-analysis.

Int Braz J Urol 2020 Apr 3;46. Epub 2020 Apr 3.

Department of Thoracic Surgery, The Second Affiliated Hospital of Nanchang University, Nanchang, China.

Purpose: Radical nephrectomy (RN) is the standard surgical type for pathological stage T3a (pT3a) renal cell carcinoma (RCC). Recently, some studies have suggested equivalence between partial nephrectomy (PN) and RN for oncologic control and have shown the benefits of PN for better renal function. We conducted this meta-analysis to assess oncologic outcomes, perioperative outcomes and renal function between two groups among patients with pT3a RCC. Read More

In recent years, immune checkpoint inhibitors have become the most important drugs for treating renal cell carcinoma. In combination with performing nephrectomies, tyrosine kinase inhibitors have been used as neoadjuvant therapy, as they reduce the size of a primary renal mass and cause the disappearance of metastatic lesions. However, there are only a few reports on immune checkpoint inhibitors as neoadjuvant therapy. Read More
