OBJECTIVES: To compare optimal outcome achievement between open and robotic partial nephrectomy. PATIENTS AND METHODS: Using our institutional partial nephrectomy database, we reviewed 605 cases performed for unifocal clinical T1 renal masses in non-solitary kidneys from 2011-2015. Tetrafecta, which was defined as negative surgical margins, freedom from perioperative complications, ≥80% renal functional preservation, and no chronic kidney disease upstaging, was chosen as the composite optimal outcome...

A 65-year-old female presented to clinic requesting follow up for a history of right robotic partial nephrectomy done at an outside institution 2 years prior. Initial pathology demonstrated a grade 2/4 3.4 cm clear cell renal cell carcinoma with negative margins. There was no tumor necrosis, sarcomatoid differentiation, or lymphovascular invasion. High quality follow up imaging initially revealed a pseudoaneurysm in the central portion of the right kidney. The patient was sent to interventional radiology for angioembolization...

INTRODUCTION: A renorrhaphy technique which is effective for hemostasis but does not place undue tension on the branch vessels of the renal sinus remains one of the challenging steps after hilar tumor resection during robotic partial nephrectomy (RPN). The published V-hilar suture (VHS) technique is one option for reconstruction after an RPN involving the hilum. The objective of this video is to show a novel renorrhaphy technique, Hilar Parenchymal Oversew that has been effective for such cases...

OBJECTIVES: The complexity of partial nephrectomy (PN) is partly anticipated by morphometric tumor-based scores that do not consider patient-related issues such as adherent perinephric fat (APF). Also, the objective is to prospectively assess the predictive factors of APF during PN, its effect on complications, and to correlate it to the histological reality. METHODS: A total of 125 consecutive patients undergoing robotic or open PN were prospectively included. The Mayo adhesive probability score (MAP score) was compared to the peroperative presence of APF defined by a score≥2...

Indocyanine Green (ICG) is frequently used during urologic robotic procedures and is generally considered to be safe. However, there are reported cases of severe complications from ICG when used for non-urologic purposes. We present the first case to our knowledge of anaphylactic shock in response to intravenous ICG during a robotic partial nephrectomy.

Renal function after partial nephrectomy (PN) may depend on modifiable factors including ischemia time, excision of healthy parenchyma (excisional volume loss, EVL), and reconstructive methods. We retrospectively reviewed our institutional robotic PN database to identify the predictors of glomerular filtration rate (GFR) preservation (GFR-P) at 3-12 mo postoperatively, during which GFR decline plateaus. Baseline clinical, sociodemographic, and radiologic characteristics were captured. Univariate and multivariate (MV) linear regression analyses were performed and marginal effects were employed to examine the relative effect of EVL on renal function...

A duplex kidney system with an ectopic ureter draining into the vagina is a congenital malformation that typically presents as refractory urinary incontinence. Diagnosis is often difficult to establish and delayed due to a low incidence. We present the case of a patient aged 26 years with a life-long history of persistent urinary incontinence. Initial presentation was at childhood; however, the diagnosis went undetermined for 22 years. CT urography revealed a duplex kidney with an atrophic upper pole associated with an ectopic ureter that drained into the vaginal vault...

Robotic partial nephrectomy (RPN) is gaining increasing prominence for nephron-sparing surgery in the treatment of patients with localized kidney tumors. RPN offers the benefits of minimally invasive surgery with a shorter learning curve compared with its laparoscopic counterpart. While long-term data are awaited, RPN does provide short-term oncologic and functional outcomes comparable to open and laparoscopic partial nephrectomy. Furthermore, robotic surgery has facilitated technical innovation, including the elimination of warm ischemia, provided minimally invasive alternatives to patients with complex tumors, and importantly, has fuelled increased dissemination of partial nephrectomy surgery among community urologists...

To construct patient-specific physical three-dimensional (3D) models of renal units with materials that approximates the properties of renal tissue to allow pre-operative and robotic training surgical simulation, 3D physical kidney models were created (3DSystems, Rock Hill, SC) using computerized tomography to segment structures of interest (parenchyma, vasculature, collection system, and tumor). Images were converted to a 3D surface mesh file for fabrication using a multi-jet 3D printer. A novel construction technique was employed to approximate normal renal tissue texture, printers selectively deposited photopolymer material forming the outer shell of the kidney, and subsequently, an agarose gel solution was injected into the inner cavity recreating the spongier renal parenchyma...
