BACKGROUND Papillary renal-cell carcinoma, which accounts for 15 to 20% of renal-cell carcinomas, is a heterogeneous disease that consists of various types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary(More)
BACKGROUND Nephroureterectomy alone fails to adequately treat many patients with advanced upper tract urothelial carcinoma (UTUC). Perioperative platinum-based chemotherapy has been proposed but requires adequate renal function. OBJECTIVE Our aim was to determine whether the ability to deliver platinum-based chemotherapy following nephroureterectomy is(More)
PURPOSE We assessed the success of retrograde placement of indwelling ureteral stents in the management of ureteral obstruction due to extrinsic compression. MATERIALS AND METHODS Between July 1987 and December 2002 adequate followup was available for 101 patients who underwent primary retrograde ureteral stenting for extrinsic ureteral obstruction. Mean(More)
We studied the usefulness of radiography for localization of cryptorchid testes. A total of 23 radiographic studies ordered by referring physicians was done for testis localization in 18 boys. Two patients had retractile testes and were followed expectantly. Ultrasonography failed to detect palpable testes in both cases. A total of 16 boys (19 undescended(More)
Transplantation of kidneys from donors over the age of 60 yr is controversial. However, as the demand for cadaveric kidneys far exceeds the supply, exploration of the usefulness of kidneys outside the currently accepted donor pool is necessary. Between January 1987 and July 1989, 31 (5.5%) of the 558 cadaveric renal transplants performed at the University(More)
PURPOSE The POSSUM (Physiological and Operative Severity Score for Enumeration of Mortality and Morbidity) and Portsmouth POSSUM predictor equations are scoring systems validated in the general surgery literature that estimate postoperative morbidity and mortality risk. We tested the validity of POSSUM and Portsmouth POSSUM in patients undergoing radical(More)
OBJECTIVE To perform a contemporary comparative cost-analysis of robotic-assisted laparoscopic radical prostatectomy (RARP) and open radical retropubic prostatectomy (RRP). METHODS All patients undergoing RARP (n = 115) or RRP (n = 358) by 1 of 4 surgeons at a single institution during a 15-month period were retrospectively reviewed. The hospital length(More)
PURPOSE We present our early experience with the novel approach of placing 2 parallel stents simultaneously in extrinsically obstructed ureters in which single stents had failed. The increased stiffness of 2 stents reduces kinking and luminal compression, and the potential space between the stents likely preserves flow around as well as through them. (More)
PURPOSE The purpose of this report is to discuss the current treatment options available to the patient with prostate cancer in all stages of the disease. OVERVIEW With the exception of skin cancer, prostate cancer is the most common cancer in men in the United States. Most patients in the current era will present with organ-confined disease, amenable to(More)
