Benign prostatic hyperplasia is commonly treated with alpha-adrenergic-receptor antagonists (alpha-blockers) or 5alpha-reductase inhibitors. The long-term effect of these drugs, singly combined, on the risk clinical progression unknown.We conducted a long-term, double-blind trial (mean follow-up, 4.5 years) involving 3047 men to compare effects placebo, doxazosin, finasteride, and combination therapy measures benign hyperplasia.The overall progression--defined as an increase above base line...
In carcinoma of the bladder, both intravesical chemotherapy and immunotherapy can induce tumor regression reduce rate recurrence, but relative merits these two therapies are unclear. We conducted a multi-institutional study to address this question.
Radical cystectomy remains associated with significant morbidity. Most series report outcomes relatively short-term followup that may underestimate the true magnitude of procedure and many length hospital stay but ignore readmission rates. We analyzed predictors early (30 days or less), late (31 to 90 days) cumulative 90-day readmissions, as well morbidity mortality rates.We reviewed our prospectively collected database 753 patients who underwent radical for urothelial cancer between January...
Abstract Cribriform prostate cancer, found in both invasive cribriform carcinoma (ICC) and intraductal (IDC), is an aggressive histological subtype that associated with progression to lethal disease. To delineate the molecular cellular underpinnings of ICC/IDC aggressiveness, this study examines paired benign surgical samples by single-cell RNA-sequencing, TCR sequencing, histology. cancer cells express genes metastasis targets potential for therapeutic intervention. Pathway analyses...
We examined our recent series of patients who underwent radical cystectomy to determine and analyze the early perioperative morbidity procedure in a contemporary treated with guidance clinical pathway.We reviewed records 304 consecutive from December 1995 July 2000. specifically evaluated complications that developed within 30 days procedure. Potential variables predictive were analyzed, including patient age, gender, race, American Society Anesthesiologists score, type urinary diversion,...
Surgical technique, patient characteristics and method of pathological review may influence surgical margin status. We evaluated the incidence location positive margins in 200 sequential robotic assisted laparoscopic radical prostatectomy open retropubic cases.From July 2002 until December 2006 a total 1,747 patients underwent at our institution (robotic 1,238, 509). From these we selected last consecutive prostatectomies performed before August 2006. Preoperative clinical including age,...

Poor preoperative nutritional status is a risk factor for adverse outcomes after major surgery. We evaluated the effect of deficiency on perioperative mortality and overall survival in patients undergoing radical cystectomy bladder cancer.A total 538 underwent urothelial carcinoma between January 2000 June 2008, had parameters documented. Patients with albumin less than 3.5 gm/dl, body mass index 18.5 kg/m(2) or weight loss greater 5% were considered to have deficiency. Primary 90-day...

The feasibility of laparoscopic or robotic assisted radical cystectomy has been demonstrated in several small series, but the specific advantages are uncertain and require comparisons to more recent results that incorporate refinements open technique perioperative management. We reviewed our contemporary series evaluate outcome measures which could be affected by surgical approach for purpose establishing benchmarks future comparisons.The medical records 553 consecutive patients undergoing...
Health related quality of life after urinary diversion has been increasingly recognized as an important outcome measure.

Therefore, we health in who underwent versus creation using questionnaires.We mailed 2 questionnaires that are measures life, namely the RAND 36-Item Survey (SF-36) Functional Assessment Cancer Therapy-General (FACT-G),...
Minimally invasive surgery has been shown to decrease postoperative morbidity and length of stay for a number surgical procedures. Furthermore, after open radical prostatectomy decreased dramatically during the last decade. We examined differences in between prospectively evaluated cohort patients who underwent retropubic robot assisted laparoscopic prostatectomy.Between January 2003 March 2006, 1,003 prostatectomies were performed at our hospital. Data collected prospective fashion...

Prostatic carcinoma (Pca) at cystoprostatectomy is usually an incidental finding with the majority thought to be clinically insignificant. Most studies have not specifically addressed location of Pca or incidence and in situ invasive urothelial (Uca) prostates specimens. The frequency involvement apex these processes has clinical implications. Specifically urinary continence following orthotopic diversion may enhanced by prostate apical sparing. In this study pathological features Uca, were...
