Therapy (case series).4.To present our institution's experience of selective embolization renal angiomyolipomas with alcohol and the long-term follow up data.This retrospective study included 34 patients treated between October 1997 2007 (29 women five men, mean age 44 years). Of these patients, nine had tuberous sclerosis, 14 were bilateral 16 multifocal. Indications for treatment previous haemorrhage (14), size >4 cm (19) increasing over a short period (one).

It is widely recognised that sorafenib inhibits a range of molecular targets in renal cell carcinoma (RCC). In this study, we aim to use patient-derived RCC xenografts delineate the angiogenic and non-angiogenic therapy for advanced (aRCC). We successfully generated three patient RCC-derived severe combined immunodeficient mice, consisting different histological subtypes: conventional clear cell, poorly differentiated with sarcomatoid changes, papillary RCC. This study also used cells...

Background and Purpose: During laparoscopic nephrectomy (LPN), a stapling device is often used for vascular control, especially of the renal vein. Herein, we report our experience using polymer clip (Hem-o-lok) routine control vessels during LPN in animal clinical setting. Patients Methods: Fifty ablative fifteen live-donor nephrectomies were performed domestic pigs. Hem-o-lok clips (10 mm; Weck Closure System, Research Triangle Park, NC) routinely control. In addition, from January 2001 to...

The incidence of lymphoceles -lymphatic collections around a transplanted kidney -can be as high 20%.We aimed to review the presentation, treatment and outcome patients with lymphoceles. METHODSWe reviewed prospective database 154 who underwent renal transplantation at our hospital from January 2005 November 2008. RESULTSThe mean age in cohort was 46 (range 34-58) years.The series 5.8% (n = 9).The median onset 19 6-28) days post-transplantation, while size 5 1.5-8) cm.Lymphoceles were most...

Objective To evaluate the incidence and management of local systemic complications afflicting patients with de novo metastatic prostate cancer (mPCa) in Singapore. Design Retrospective analysis a large prospective Uro-oncology registry mPCa. Setting This study is carried out tertiary hospital Participants We reviewed our institution’s prospectively maintained database 685 mPCa over 20-year period (1995–2014). Patients non-mPCa or those progressed to disease after previous curative treatments...

OBJECTIVE To assess the effect of ageing and body mass index (BMI) on prostate-specific antigen (PSA) among Chinese men from results 2005 Prostate Awareness Week in Singapore. SUBJECTS AND METHODS In all, 2714 participated programme, consisting 2431 Chinese, 114 Malays, 117 Indians 52 'others'. Of these, 2410 who had a PSA level <20 ng/mL were aged >50 years but <80 included analysis. Height weight used to calculate BMI. The relationship between age levels was analysed using linear...

To assess the factors that influence onset of androgen independence (AI, which heralds a dismal outcome) in patients with metastatic prostate carcinoma.The records 361 consecutive carcinoma diagnosed and treated authors' institution from 1 January 1996 to 31 December 1999 were reviewed retrospectively; 92 assessed (median age 71.0 years, range 42-93). Patients included if they developed disease cancer at time diagnosis. The nadir for specific antigen (PSA) level was defined as date lowest...

In this paper, a prototype of robotic system for accurate and consistent insertion percutaneous biopsy needle into the prostate is presented. A transrectal ultrasound (TRUS) probe used to collect series two-dimensional (2D) images prostate. These are create 3D computer model organ which by urologist define points within The then calculates required trajectory needle, can be simulated on computer. Following this, robot configured accordingly actual performed. Cadaveric human trials have...

We report a case of prostatic ductal adenocarcinoma which expressed thyroid transcription factor-1 (TTF-1) on immunohistochemical examination, and highlight the fact that this aberrant staining is potential pitfall in evaluation lesion. Prostatic core biopsy specimens from 65-year-old man revealed an with large-calibre glands lined by stratified hyperchromatic nuclei. There was no accompanying conventional acinar TTF-1 distinctly positive nuclei malignant cells. This led to search for...

Spontaneous regression of cancer is a rare, but well documented, phenomenon. We present unique case an 82 year old Chinese male who experienced spontaneous histologically-verified metastatic type II papillary renal cell carcinoma in the absence intervening systemic therapy or surgery. This first reported carcinoma. The mechanism remains unknown, and represents challenge for existing oncology paradigms.

Community involvement is arguably a key component behind sustainable heritage management. Under strict government control, however, local community-led initiatives are difficult to find in China. Nonetheless, through remittances and philanthropic contributions their respective communities, the Chinese diaspora have long been seen as an important source of foreign capital driving force homeland development. A transregional study (mainland China, Hong Kong Canada) was carried out explore...
