OBJECTIVE This study was an attempt to identify key CT features that can potentially be used to differentiate between lipid-poor renal angiomyolipoma and renal cell carcinoma (RCC). MATERIALS AND METHODS We conducted an analysis of patients who received nephrectomy or renal biopsy from 2002 to 2011 with suspected RCC. We included tumors smaller than 7 cm(More)
Initial access into the peritoneum and establishing pneumoperitoneum are required for laparoscopy. Various techniques have been described to achieve insufflation and place trocars. We describe our method of initial entry into the upper quadrant and subsequent incorporation of this site as a working port during upper urinary tract laparoscopy. This is an(More)
Renal cell carcinoma (RCC) in autosomal dominant polycystic kidney disease (ADPKD) is very rare. Only 11 cases of bilateral RCC in ADPKD have been reported since 1954. Herein, we present a 58-year-old male who received laparoscopic bilateral radical nephrectomy for bilateral RCC with different cell variants in ADPKD and end-stage renal disease under regular(More)
PURPOSE We studied the correlation between serum prostate specific antigen and the volume of different zones of the prostate in Taiwanese men with biopsy proven benign prostatic hyperplasia. MATERIALS AND METHODS A total of 233 patients with a mean age of 71.4 years (range 42 to 89), serum prostate specific antigen less than 10 ng/ml and pathologically(More)
BACKGROUND Discordance between the Gleason scores of prostate needle biopsies and radical prostatectomy specimens has been reported by several investigators. We conducted this study to determine if increasing the number of prostate needle biopsies in patients with prostate cancer improves the accuracy of Gleason scores in the Taiwanese population. METHODS(More)
BACKGROUND Renal oncocytoma has been reported mostly in the Western literature, and only a few cases have been reported in Eastern populations. In the present study, we review the clinical course of renal oncocytoma in our institution. METHODS We obtained the files of 13 cases of renal oncocytoma between 1988 and 2006 from the pathological archives of(More)
OBJECTIVES To compare the renal outcomes in patients of unilateral renal cell carcinoma (RCC) with upper tract urothelial carcinoma (UTUC) following surgical resection of the tumor-bearing kidney, and to investigate the potential predictors in renal function decline. PATIENTS AND METHODS In this retrospective cohort study, 319 RCC patients undergoing(More)
Lymphangioma manifesting in the genitourinary tract is an uncommon disease. Cystic lymphangioma is a congenital lymphatic hamartoma known as lymphatic malformation. Herein we report 2 cases of lymphangioma of male exogenital organs. After complete excision of the tumor and subsequent follow-up for 6 months, both of them were free of recurrence.(More)
BACKGROUND Laparoscopic partial nephrectomy (LPN) is a definitive therapy in patients with a small renal tumor. The aim of this study was to present our interim results of LPN with its complications and outcomes. METHODS We conducted a retrospective chart review of 46 LPNs in 45 patients at Taipei Veterans General Hospital from April 2004 to September(More)
BACKGROUND We present our experience of complications of pure transperitoneal laparoscopic surgery in urology at Taipei Veterans General Hospital. METHODS Between September 2003 and March 2006, 185 laparoscopic urologic operations were performed, consisting of 70 nephrectomies (36 radical, 17 partial, 11 simple, 6 donor), 28 adrenalectomies, 28(More)
