OBJECTIVE Treatment decisions regarding the use of retroperitoneal lymph node dissection (RPLND) for low-stage and advanced testicular cancer may be influenced by the morbidity of the procedure. We sought to compare the complication profile of primary (P-) and post-chemotherapy (PC-) RPLND using a standardized complication grading scale. MATERIALS AND(More)
OBJECTIVES To review our experience with radical nephrectomy and inferior vena cava thrombectomy (RNIVCT) to determine the utility of preoperative embolization. Preoperative embolization has been used as an adjunctive procedure to facilitate surgical resection of complex renal tumors. METHODS From 1990 to 2007, 225 patients with renal tumors and inferior(More)
Background A 25-year-old male presented to his local urologist with new-onset right testicular pain and swelling detected on self examination. A scrotal ultrasound scan showed a right testicular mass, suspicious for neoplasm. Serum levels of α-fetoprotein and human chorionic gonadotropin were found to be elevated at 920.2 µg/l and 637.4 U/l, respectively.(More)
PURPOSE alpha-Melanocyte stimulating hormone protects kidneys against ischemia and sepsis induced acute kidney injury in rodents. We examined the efficacy of alpha-melanocyte stimulating hormone analogue AP214 to protect against acute kidney injury in higher vertebrates. MATERIALS AND METHODS We performed a prospective, blinded, randomized, placebo(More)
A case of carcinosarcoma of the prostate in a previously healthy 65-year-old man is reported. The tumor was initially diagnosed as adenocarcinoma, but the prostatectomy specimen showed a 717-g prostate, with evidence of adenocarcinoma and carcinosarcoma without heterologous structures. By 3-month follow-up, local recurrence, and liver, lung, and bone(More)
Limb salvage is a viable alternative to amputation in many cases of advanced sarcoma. The authors examined their experience with microvascular reconstruction of upper extremity defects after sarcoma resection, focusing on oncologic and functional outcomes. A retrospective analysis yielded 17 patients who underwent 18 free flap procedures and met the(More)
Urologists are integrally involved in the management of acute kidney injury (AKI), which is common after renal surgery or secondary to postrenal (obstructive) etiologies. The measurement of serum creatinine is a suboptimal indicator of AKI because it lags behind acute changes in renal function. Recent advances indicate that serum/urine biomarkers will prove(More)
A 23-year-old woman was evaluated for right flank pain of one year duration. Magnetic resonance imaging (MRI) revealed a 6 cm defect in the right hemidiaphragm with herniation of the right kidney, adrenal gland, and posterior right hepatic lobe consistent with a congenital right Bochdalek hernia. Computed tomography (CT) urogram confirmed lack of masses,(More)
A potentially devastating sequela of brachial artery injury in the setting of upper extremity trauma is the development of compartment syndrome (CS). We performed a retrospective review of 139 trauma patients with brachial artery injury from 1985-2001. Objective characteristics of each case were extracted and analyzed using multivariate logistic regression.(More)
