Abstract Purpose: An accurate system for predicting survival patients with solid tumors will allow better patient selection both established and novel therapies. We propose a staging clear cell variants of renal carcinoma (RCC) that includes molecular predictors standard clinical such as tumor-node-metastasis (TNM) stage, histological grade, performance status (PS). Experimental Design: A custom tissue array was constructed using RCC from 318 patients, representing all stages localized...

Upper pole tumors with direct extension into the adrenal gland are currently staged as pT3a in 1997 TNM staging system. To determine whether clinical behavior of differs from that perinephric fat invasion (also stage pT3a) a retrospective analysis was performed.Of 1,087 patients who underwent nephrectomy 27 were identified involvement and 187 or renal sinus involvement. Variables outcomes analyzed each group included percent metastatic disease at presentation, lymph node involvement, Eastern...

We assessed outcomes in children with ureterocele after transurethral incision at our institution between 2001 and 2014, focusing on end points of vesicoureteral reflux, improvement hydronephrosis need for second surgery.We performed chart reviews 83 patients, collecting information including age incision, gender, renal anatomy, location, indication preincision postincision reflux status. Patients were divided into those single system duplex ureteroceles, intravesical extravesical location...
Objective: To investigate the efficacy of using intentionally cryopreserved epididymal sperm in selected cases obstructive azoospermia.Design: A retrospective, nonrandomized study.Setting: Academic research environment.Patients: One hundred forty-one couples undergoing first-time IVF/ICSI either fresh or sperm.Interventions: The epididymides were microsurgically aspirated.Main Outcome Measures: Clinical pregnancy rates.Results: Motile obtained from all men. For group, mean total aspirated...

In a canine model, we evaluated the feasibility of nerve-sparing cryosurgery by active warming neurovascular bundle (NVB). Furthermore, our aim was to determine if NVB increases risk acinar gland and stromal-tissue preservation in adjacent areas prostate. The effects single versus double freeze-thaw cycle on prostate tissue were also assessed.Ten lobes from five dogs evaluated. Nine treated with cryoablation using 17-gauge gas-driven cryoneedles. Seven wre helium gas, two without warming. A...
Carbonic anhydrase 9 (CA9) is the most promising molecular marker described for renal cell carcinoma (RCC) to date. We investigated whether transduction of monocytes from peripheral blood with adenovirus encoding CA9 gene (AdV-CA9) could stimulate a T-cell mediated immune response against cancer cells expressing CA9. The ability consistently generate an important step toward development CA9-specific RCC vaccine.AdV-CA9 was generated using AdEasy system. AdV-CA9-transduced mononuclear...
Re-do pyeloplasty after failed open or laparoscopic ureteropelvic junction (UPJ) obstruction correction can be a challenging procedure because of scar formation at the previous anastomosis site and decreased vascularity ureter. This study compared perioperative parameters for pediatric robot-assisted (RAL) primary re-do pyeloplasties with an emphasis on intra-operative parameters.We RAL procedures performed by single surgeon tertiary care children's hospital both (UPJO) recurrent UPJO over...
