Partial (2/3) nephrectomy can be performed via the laparoscopic, retroperitoneal, and transperitoneal approach. Outcomes of the three approaches were compared in this study. 2/3 nephrectomy were performed in 21 healthy Bama miniature pigs (mean bodyweight 20.59±2.78kg). Pigs were divided into three groups: those that underwent 2/3 nephrectomy via laparoscopy (LN group, n=7), the retroperitoneal approach (RN group, n=7), or the transperitoneal approach (TN group, n=7). We monitored pre- and postoperative physiologic parameters, blood cell count, and stress and renal function biomarkers...

Purpose: To evaluate the clinical safety and natural history of active surveillance (AS) for incidentally diagnosed small renal mass (SRM). Materials and Methods: We analyzed prospective data for patients who underwent AS for SRM. From 2010 to 2016, 37 SRMs of less than 3 cm were registered. Computed tomography (CT) and magnetic resonance imaging were used for initial diagnosis and CT, ultrasonography, and chest CT were performed at 6-month intervals. If there was no change in size during 2 years, follow-ups were performed annually...

Background: To assess the prognostic and predictive factors of time to treatment failure (TTF) and overall survival (OS), respectively, in patients with metachronous metastatic renal cell carcinoma (mRCC) who were treated with targeted agents. Materials and Methods: We retrospectively reviewed metachronous mRCC patients, defined as individuals diagnosed with metastatic disease >3 months after initial nephrectomy, treated at an institute since 2005. Cox proportional hazard regression analysis was performed to discover the most determinant variables associated with TTF and OS...

The standard of care treatment for solitary renal cell carcinoma (RCC) tumors 4 cm or less is partial nephrectomy (PNx). However, multifocal kidney cancer presents unique challenges for treating physicians. Historically, total nephrectomy and hemodialysis with possible renal transplant later was the primary therapeutic strategy for these patients. Later, as nephron sparing surgical approaches improved, PNx became the standard of care for patients presenting with multifocal and hereditary RCC. Surgeries to remove multiple renal tumors simultaneously produce different perioperative outcomes and increased risk of complications...

OBJECTIVE: To assess renal function in the operated kidney at different time points post partial nephrectomy (PN) and establish the time in which optimal recovery occurs. Recovery of renal function post-PN has received significant attention. However, the optimal time to determine full recovery has not been clearly established. METHODS: Renal function following minimally invasive (laparoscopic and robotic) PNs performed between 2002 and 2015 was reviewed. Patients included in this study had renal function assessed pre-operatively as well as 3 days, 6-12 weeks, and 1 year post-PN, using a combination of estimated glomerular filtration rate (eGFR) from serum creatinine and relative renal uptake (RRU) from Tc99m-MAG3 renal scintigraphy...

Secondary kidney involvement by disseminated non-Hodgkin's lymphoma (NHL) is quite common and is estimated to approach 30 - 60% in NHL patients. However, primary renal lymphoma is exceedingly rare and estimated to make up less than 1% of all kidney masses. We report a case of primary renal NHL presenting with profound hypercalcemia and renal failure recalcitrant to medical management, ultimately treated with urgent radical nephrectomy. To our knowledge, this is the first report of primary renal lymphoma presenting in this acute fashion...

BACKGROUND: Every effort should be made to optimize surgical techniques and to minimize potential morbidity rates associated with live donor operations. Advances in a minimally invasive approach by robotic surgery to donor nephrectomy have raised the possibility of applying this technique to live donor bowel resections for intestinal transplantation. METHODS: We report the first 5 consecutive cases of a robotic-assisted live donor ileal segmentectomy. We describe the technical aspects of the procedure, discuss the rationale for considering this option, and evaluate potential advantages of this approach...

An increased risk of ESRD has been reported for living kidney donors, and appears to be higher for those donating to a relative. The reasons for this are not clear. One possibility is that ESRD may be due the nephrectomy-related reduction in GFR, followed by an age-related decline that may be more rapid in related donors. Between 1/1/1990 - 12/31/2014, we did 2002 living donor nephrectomies. We compared long-term postdonation eGFR trajectory for donors with (n=1245) versus without (n=757) a first-degree relative with ESRD...

Kidney cancer (Renal Cell Carcinoma (RCC)) is one of the most deadly malignancies due to frequent late diagnosis and poor treatment options. Histologically, RCC embraces a wide variety of different subtypes with the clear cell variant (ccRCC) being the most common, accounting for 75-90% of all RCCs. At present, the surveillance protocols for follow-up of RCC patients after radical nephrectomy are based on the American Joint Committee on Cancers (AJCC) pathological tumor-node-metastasis (TNM) classification system...

Wilms' tumour, a renal malignancy, primarily occurs in children with a peak incidence between 2 to 5 years age group and accounts for approximately 95% of childhood renal malignancies. Though rarely, it may also occur in adults with an incidence rate of less than 0.2 per million per year. Microscopically, there is no difference between Wilms' tumour of paediatric and adult age groups. But the prognosis for adults with Wilms' tumour is thought to be worse than that for children possibly due to more aggressive clinical course in case of adult Wilms' tumour...

BACKGROUND: Minimally invasive surgery is considered to be the gold standard treatment for nephrectomy in children. In recent decades it has been proposed that laparoendoscopic single-site (LESS) surgery is a feasible alternative to perform laparoscopic nephrectomies. OBJECTIVE: The aim of our study was to compare the safety and efficacy of LESS against conventional laparoscopic (CL) nephrectomy. STUDY DESIGN: From March 2010 to November 2012 charts of pediatric patients who underwent laparoscopic nephrectomy at our tertiary center were revised...

Bellini duct carcinoma is a very rare type of renal cell carcinoma (RCC), accounting for less than 1%. It arises from the distal nephron, more specifically from the collecting duct. Its morphological features are extremely variable, making its diagnosis difficult. We report the case of a 62-year old patient admitted with a painless progressive left flank swelling. CT scan showed a huge mass occupying the upper portion of the left kidney. The patient underwent radical nephrectomy. Anatomopathological examination showed collecting duct carcinoma of the kidney...

OBJECTIVE: Giant hydronephrosis (GH) is a rare entity in both developed and developing countries with less than 500 cases reported in the literature. Delayed diagnosis and management of GH, can result in long-term complications like hypertension, rupture of the kidney, renal failure and malignant change. We aim to highlight the importance of this often neglected entity and build a consensus for its early diagnosis and management. MATERIAL AND METHODS: Patients with GH were thoroughly worked up, managed and followed up between June 2013 and December 2015 and epidemiologic, radiological, perioperative and follow-up data was recorded...
