BACKGROUND Thirty percent of patients with clinically localized prostate cancer and a negative bone scan will experience relapse with recurrent disease despite treatment of the primary tumor. This may be due to the presence of metastatic prostate cancer cells at the time of treatment undetected by conventional methods, radionucleotide bone scan, and serum(More)
Laparoscopic nephrectomy with ablative intent has been performed clinically. The current study aimed to determine whether a physiologically and anatomically intact kidney suitable for transplantation could be harvested laparoscopically. Three weeks after an ablative laparoscopic right nephrectomy, 15 pigs were divided into two groups: the study group (n =(More)
The prostate apoptosis response-4 (par-4) gene was identified by differential screening for genes that are upregulated when prostate cancer cells are induced to undergo apoptosis. The par-4 gene is induced by apoptotic signals but not by growth-arresting, necrotic, or growth-stimulatory signals. The deduced amino acid sequence of par-4 predicts a protein(More)
This is the first series of total penile reconstructions with the free sensate osteocutaneous fibula flap. The main advantages of this flap lie in its intrinsic rigidity, its superior donor-site location, and its long vascular pedicle. The fibula flap provides better bone volume than does the radial forearm flap, which commonly results in a floppy phallus(More)
PURPOSE We describe a novel double loop renal parenchymal tourniquet for obtaining hemostasis during open and laparoscopic partial nephrectomy. METHODS One loop is positioned around the upper and 1 around the lower renal poles, thus securely entrapping the kidney. During partial nephrectomy the corresponding loop is double looped and cinched, thus(More)
UNLABELLED Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Female urethral stricture disease has been described for almost 200 years. The symptoms of female stricture disease may range from clinically insignificant to severe and debilitating with the exact aetiology being unclear. No strict(More)
Renal involvement is common in Henoch-Schoenlein purpura (HSP) and, while ureteral obstruction has been described in patients with the disease, it is rare. We report a female with HSP who developed bilateral ureteral obstruction from peri-ureteral vasculitis and subsequent ureteral ischemia. Hydronephrosis and typical findings on contrast urography(More)
Thirty children with urinary tract infection and nonobstructive vesicoureteral reflux have been followed prospectively for a mean of 17 months. After classification according to age and grade of reflux, 10 patients were assigned at random to treatment with antimicrobial prophylaxis alone or antimicrobial prophylaxis plus corrective surgery. Twenty other(More)
