Objective: To assess the association of histopathological parameters in non-neoplastic renal parenchyma with the development of new-onset chronic kidney disease (CKD) after radical nephrectomy.
Patients And Methods: Data were extracted from 222 patients who underwent radical nephrectomy. The Modification of Diet in Renal Disease formula was used.
We report a case of small-bowel obstruction caused by an internal hernia produced by the presence of an intraperitoneal sling mesh. A woman with a history of multiple abdominal surgeries was referred from another center after a sling procedure. On the fifth day after surgery, she developed small-bowel obstruction.

Objective: Describe the robotic and laparoscopic technique and the short-term outcomes of high extended pelvic LND (PLND) up to the inferior mesenteric artery (IMA) during RC.
Design, Setting, And Participants: From January 2007 through September 2009, we performed high extended PLND with proximal extent up to the IMA (n=10) or aortic bifurcation (n=5) in 15 patients undergoing robotic RC (n=4) or laparoscopic RC (n=11) at two institutions.
Objective: • To compare laparoendoscopic single-site (LESS) and standard laparoscopic pyeloplasty procedures with the aim of defining whether perioperative, recovery or health-related quality of life (HRQL) benefits exist for the LESS procedure.
Patients And Methods: • From November 2007 to August 2008, sixteen patients underwent LESS pyeloplasty at a tertiary care referral centre. These patients were compared with a matched cohort of patients undergoing standard laparoscopic pyeloplasty.
Purpose Of Review: As familiarity with laparoscopic partial nephrectomy (LPN) has grown, application has expanded into increasingly complex cases. In this review, we present a recent series describing use of LPN in specific clinical scenarios and describe common technical modifications commonly employed in each case. In addition, we discuss modifications to standardly performed maneuvers.

Materials And Methods: A total of 220 patients treated from June 1994 to July 2008 were included in the study. Estimated glomerular filtration rate, and overall, cancer specific and recurrence-free survival were assessed.
Background And Purpose: Percutaneous endoscopic resection is a viable treatment option for upper-tract urothelial carcinoma (UC) in selected patients. We present our experience with patients who underwent percutaneous resections for complex urothelial tumors.
Patients And Methods: Patients who were undergoing percutaneous treatment for UC were identified within a prospectively maintained database at a single institution.
Purpose Of Review: Laparoscopic partial nephrectomy (LPN) technique has continually evolved over the last decade, resulting in better outcomes and increased popularity within the urological community. In this article, we provide an overview of the contemporary literature on LPN.
Recent Findings: The technique of LPN has evolved over the last 5 years with a nearly 50% reduction of warm ischemia time in experienced hands.
Article Synopsis
- The study evaluates the long-term oncological outcomes of laparoscopic radical nephrectomy for kidney cancer, with a follow-up period averaging 11.2 years.
- A total of 73 patients underwent the procedure, with cancer-specific survival rates hitting 92% at 10 years and 78% at 12 years, showcasing impressive long-term results.
- The authors conclude that laparoscopic surgery for renal cell carcinoma provides excellent outcomes, comparable to traditional open surgeries, despite some patients developing metastatic disease.
Background: Laparo-endoscopic single site (LESS) surgery is a recent development in minimally invasive surgery. Presented herein is the initial comparison of LESS donor nephrectomy (LESS-DN) and standard laparoscopic living donor nephrectomy (LLDN).
Objective: To determine whether LESS-DN provides any measurable benefit over LLDN during the perioperative period and subsequent convalescence.
Objectives: To report our initial experience with laparoendoscopic single-site (LESS) surgery in 100 patients in urology.
Methods: Between October 2007 and December 2008, we performed LESS urologic procedures in 100 patients for various indications. These included nephrectomy (N = 34; simple 14, radical 3, donor 17), nephroureterectomy (N = 2), partial nephrectomy (N = 6), pyeloplasty (N = 17), transvesical simple prostatectomy (N = 32), and others (N = 9).
OBJECTIVE To determine whether a novel port (QuadPort, Advanced Surgical Concepts, Wicklow, Ireland) can facilitate transvaginal nephrectomy (TN), a natural orifice transluminal surgery (NOTES) procedure, using standard and articulating laparoscopic instruments. MATERIALS AND METHODS Four fresh female cadavers were used in this feasibility study with a plan to perform two right-sided and two left-sided TN. Exclusion criteria were a history of nephrectomy and a height of >1.

Recent Findings: Most studies of RaRP are observational and report perioperative, functional and short-term oncological outcomes. RaRP is associated with less blood loss and blood transfusion than open radical prostatectomy (ORP), has a positive margin rate of 9.
