Factors affecting renal function preservation among patients not achieving trifecta after laparoscopic partial nephrectomy for clinical T1a renal masses.

Introduction: The goal of partial nephrectomy for renal tumors is complete tumor removal with the preservation of renal function and no complications. Trifecta (total ischemia time < 25 minutes, negative surgical margins, and no surgical complications) is widely used to evaluate success after partial nephrectomy. We investigated factors affecting renal function preservation among patients not achieving trifecta after laparoscopic partial nephrectomy.

The efficacy of the TachoSil binding suturing technique in laparoscopic partial nephrectomy to prevent the development of pseudoaneurysm.

Objective: Our specific aim was to introduce the TachoSil binding suturing technique for renal cell carcinoma (RCC) patients when closing the parenchymal defect after tumor excision during laparoscopic partial nephrectomy (LPN), which is a novel technique for reducing the risk of developing subsequent pseudoaneurysm (PA).

Methods: We identified 113 pT1aN0M0 RCC patients who underwent LPN at our institution. Eighty-one (72%) patients underwent the suturing procedure without binding TachoSil, whereas 32 (28%) patients underwent renorraphy with the renal defect closed together with TachoSil.

Early tumor shrinkage as a predictive factor of metastatic renal cell carcinoma in molecular targeted therapy: A single institutional study.

The aim of the present study was to investigate the impact of metastatic sites and early tumor shrinkage (eTS) as prognostic predictive factors of metastatic renal cell carcinoma (mRCC) in molecular targeted therapy. A total of 209 advanced RCC cases treated with sorafenib, sunitinib, axitinib, pazopanib, temsirolimus and everolimus from our single institution were included in the present study. Several known prognostic predictive factors, including metastatic sites and the rate of eTS, were analyzed by Kaplan-Meier survival estimate analysis followed by Cox's proportional hazards model analysis.

Female Functional Constipation Is Associated with Overactive Bladder Symptoms and Urinary Incontinence.

This noninterventional cross-sectional study aims to assess the association between functional constipation (FC) and urinary symptoms in female patients with no treatment for urination and defecation. The Rome III criteria for evaluation of defecation, Overactive Bladder Symptom Score (OABSS) for evaluation of urinary symptoms, and clinical features were investigated in 145 female patients. Latent FC and moderate to severe overactive bladder (OAB) were defined on the basis of positivity for two or more of the Rome III criteria and an OABSS ≥ 6 with OABSS Q3 ≥ 2, respectively.

Determining When to Stop Prostate Specific Antigen Monitoring after Radical Prostatectomy: the Role of Ultrasensitive Prostate Specific Antigen.

Purpose: We analyzed long-term followup data after radical prostatectomy to determine how long we should follow patients in whom the serum prostate specific antigen level measured by an ultrasensitive assay was consistently low.

Materials And Methods: We retrospectively reviewed clinicopathological data for 582 consecutive patients who underwent open or laparoscopic radical prostatectomy between 1995 and 2004, excluding 4 patients who received adjuvant therapy. We stratified the patients according to prostate specific antigen at 3 and 5 years after surgery, and examined subsequent biochemical recurrence (elevation of prostate specific antigen to greater than 0.

Technical Improvement Using a Three-Dimensional Video System for Laparoscopic Partial Nephrectomy.

Background: Laparoscopic partial nephrectomy is one of the major surgical techniques for small renal masses. However, it is difficult to manage cutting and suturing procedures within acceptable time periods. To overcome this difficulty, we applied a three-dimensional (3D) video system with laparoscopic partial nephrectomy, and evaluated its utility.
