PURPOSE We evaluated pathological variables of testicular sex cord-stromal tumors, management options and clinical outcomes. MATERIALS AND METHODS We retrospectively reviewed the records of 48 patients with testicular sex cord-stromal tumors treated at Memorial Sloan-Kettering Cancer Center between 1997 and 2012. Clinical outcomes were compared based on(More)
PURPOSE We analyzed the incidence of and risk factors for complications and conversions in a large contemporary series of patients treated with urological laparoendoscopic single site surgery. MATERIALS AND METHODS The study cohort consisted of consecutive patients treated with laparoendoscopic single site surgery between August 2007 and December 2010 at(More)
OBJECTIVE To investigate efficacy of neoadjuvant tyrosine kinase-inhibitor therapy (TKI) before imperative nephron-sparing surgery (NSS), as NSS in patients with large locally advanced or centrally located tumours can be challenging, and TKI therapy might result in a reduction of primary tumour burden and increase the feasibility of NSS. PATIENTS AND(More)
Introduction. To evaluate the association between preoperative neutrophil-lymphocyte ratio (NLR) and clinicopathologic characteristics in patients with small renal masses (SRM). Methods. Retrospective chart reviews of patients with renal masses ≤4 cm who underwent nephrectomy from January 2007 to July 2012 were conducted. Multivariable linear regression was(More)
Approximately 5% of all patients diagnosed with testicular cancer may have contralateral intratubular germ cell neoplasia (ITGCN) and may develop contralateral germ cell tumor. Here, we present a historical review and current literature regarding ITGCN and partial orchiectomy. The PubMed world literature search was performed for articles written in the(More)
PURPOSE We analyzed the 23-year Memorial Sloan Kettering Cancer Center experience with surgical resection, and concurrent adrenalectomy and lymphadenectomy for locally advanced nonmetastatic renal cell carcinoma. MATERIALS AND METHODS We retrospectively reviewed the records of 802 patients who underwent nephrectomy with or without concurrent adrenalectomy(More)
PURPOSE We describe our multi-institutional experience using a laparoscopic clamp to induce selective regional ischemia during robot-assisted laparoscopic partial nephrectomy (RALPN) without hilar occlusion. PATIENTS AND METHODS A retrospective review of Institutional Revew Board-approved databases of patients who underwent selective regional clamping(More)
INTRODUCTION Visceral adiposity has been inconsistently associated with clinicopathologic features and outcomes of clear cell renal cell carcinoma (ccRCC); however, most studies were conducted in non-Western populations. We evaluated the associations between visceral and subcutaneous adiposity and clinicopathological characteristics of non-metastatic ccRCC(More)
OBJECTIVE To prospectively compare outcomes of laparoendoscopic single-site and multiport laparoscopic radical nephrectomy and partial nephrectomy, focusing on postoperative pain and analgesic requirement. METHODS Nonrandomized, prospective comparison of laparoendoscopic single-site and multiport laparoscopic radical nephrectomy and partial nephrectomy.(More)
OBJECTIVE To analyze factors impacting postoperative renal function after open partial nephrectomy using both the clampless and clamped warm-ischemic technique. METHODS We studied a cohort of patients who underwent clamped partial nephrectomy (n = 164) and clampless partial nephrectomy (n = 64) from March 2002 to March 2009 with ≥ 12-months follow-up.(More)
