Curvature recurrence requiring surgical intervention occurred in 7.6% of patients, penile shortening occurred in 8. Mon, 07 Jul 2008 01:00:00 PDT http://www.medicalnewstoday.com/articles/114086.php ORLANDO, FL (UroToday.com) - Various techniques have been described to increase the success of retrieving sperm from testicular tissue in men with Non obstructive azoospermia. The authors describe a novel approach utilizing immunoflurescent labelled antibodies (fluorescein isothiocyanate (FITC)-conjugated mouse anti-Human acrosomal IgM antibody (HS-14)). This antibody was injected into exposed seminiferous tubules of an animals. Mon, 07 Jul 2008 01:00:00 PDT http://www.medicalnewstoday.com/articles/114085.php ORLANDO, FL (UroToday.com) - Pathologic stage T0 (pT0) rates following radical cystectomy (RC) alone range from 10-15%. The pT0 rate increases in patients that have received neoadjuvant platinum-based chemotherapy. Survival in patients that achieve pT0 status is significantly improved compared to patients with residual invasive disease. Increasingly clinicians are questioning the necessity for RC in patients that can be identified as pT0 in the bladder after chemotherapy. Mon, 07 Jul 2008 01:00:00 PDT http://www.medicalnewstoday.com/articles/114084.php ORLANDO, FL (UroToday.com) - Testicular sperm extraction (TESE), in combination with intracytoplasmic sperm injection.

Mon, 07 Jul 2008 00:00:00 PDT http://www.medicalnewstoday.com/articles/114062.php ORLANDO, FL (UroToday.com) - Analysis of SEER data suggests that few patients receive an orthotopic diversion. In 1997, 5% of patients had an orthotopic diversion and this only increased to 11% in 2005. Younger male patients with private insurance were most likely to have an orthotopic diversion. Elevated BMI leads to more complications, but no difference in major complications. Mon, 07 Jul 2008 00:00:00 PDT http://www.medicalnewstoday.com/articles/114059.php ORLANDO, FL (UroToday.com) - Abstract 71 reported that cadaveric acellular matrix graft was effective during urethroplasty with a 50% success rate. Abstracts 22 and 23 reported the keys to treating a recto-vesical fistula is urinary and fecal diversion and tissue interposition. By doing this urinary and fecal continence should be restored.

The vast majority of men will have medical management for their Peyronie's disease. There were no discernible predictive factors for those men who have a good or bad outcome. Shockwave therapy was not effective in Peyronie's disease. However, after surgical correction of the plaque, men experience less stress and an improvement in psychosocial factors. Sun, 06 Jul 2008 00:00:00 PDT http://www.medicalnewstoday.com/articles/114046.php ORLANDO, FL (UroToday.com) - (Reported from the Annual Meeting of the American Urological Association) Most of the abstracts suggested that robotic surgery is as effective as open or laparoscopic surgery regarding oncological and functional outcomes. Casey et.al., suggested that a laparoscopic cystectomy was more cost effective than open cystectomy, in part due to not needing the patient to stay in the ICU after robotic cystectomy. Sat, 05 Jul 2008 00:00:00 PDT http://www.medicalnewstoday.com/articles/114013.php A randomized trial that studied the impact of the new vitespen vaccine, administered after surgery for kidney cancer, failed to demonstrate an increase in recurrence-free survival (RFS). More research is needed, according to the study authors, in order to know whether the vaccine can increase RFS if given to patients during the early stages of the disease.

If there is no residual tumor (NRT) on the repeat TURBT patients do much better than if there is residual tumor (SRT). NRT - Recurrence 17% - Progression 10% - DFS 78% SRT - Recurrence 45% - Progression 23% - DFS 50% Abstract 1695 showed that 60% of all bladder cancer deaths occur within the first 2 years of diagnosis. Sat, 05 Jul 2008 00:00:00 PDT http://www.medicalnewstoday.com/articles/113875.php New research published in The Lancet suggests that sex-matching kidney donors and recipients may result in better outcomes. The report finds that when females receive a male donor kidney, they have higher rates of graft failure compared to the other three combinations of donor and recipient. These findings imply that future studies and decisions about organ donations should take sex into consideration. Fri, 04 Jul 2008 03:00:00 PDT http://www.medicalnewstoday.com/articles/113967.php Insightful updates on onco-urological issues were the focus of the 3rd ESU masterclass, which started in Barcelona on Friday 27 June. There were 150 participants who listened to a faculty of 12 internationally renowned experts in urological cancers. The European Board of Urology (EBU) organised a written examination following the masterclass which is accredited within the EU-ACME programme.
