PURPOSE Idiopathic retroperitoneal fibrosis (IRPF) is an unusual progressive illness for which consistent therapeutic recommendations have not been devised. The present report describes a collaborative nephrology and urology approach to distinguish IRPF from secondary disease and then combine necessary acute surgical or radiological intervention with(More)
OBJECTIVES Symptoms of benign prostatic hyperplasia affect men increasingly as they age. Minimally invasive therapies for the treatment of benign prostatic hyperplasia continue to evolve. We describe histotripsy, a noninvasive, nonthermal, focused ultrasound technology for precise tissue ablation, and report the initial results of using histotripsy for(More)
Four children, ages 3 to 8 years, developed pneumatosis intestinalis (PI) after allogeneic bone marrow transplantation (BMT) for acute leukemia or severe aplastic anemia. PI was detected at a median of 48 days (range, 10–63 days) after BMT and was associated with abdominal symptoms and clinical signs. All patients had severe systemic and/or high-grade(More)
PURPOSE The feasibility of histotripsy (transcutaneous nonthermal mechanical tissue fractionation) was previously demonstrated in an in vivo rabbit renal cortex model. We explored the spectrum of histotripsy bio-effects on different tissue types in an in vitro porcine kidney model. MATERIALS AND METHODS Using an 18 element focused annular array ultrasound(More)
OBJECTIVES To investigate the significance of focal positive margins (FPM) in prostatectomy patients. The significance of FPM after radical prostatectomy is unclear. The implication is that FPM are surgically induced, may not represent true tumor extension beyond the prostate, and thus would not affect disease-free survival (DFS). METHODS Data were(More)
A 17-year-old boy presented with Fournier gangrene associated with previously undiagnosed Crohn ileocolitis. Fournier gangrene was managed by débridement, broad-spectrum antibiotics, and hyperbaric oxygen. A diverting ileostomy was performed before skin grafting and scrotal reconstruction. Microscopy of a full-layer surgical sample from the terminal ileum(More)
Upper tract transitional cell carcinoma (TCC) accounts for approximately 5% of urothelial tumors. Surgical therapy for upper tract TCC is based on tumor grade, stage, location, and confounding factors of individual cases. Options for treatment range from minimally invasive procedures, such as ureteroscopy, to open nephroureterectomy. Laparoscopic(More)
Three patients with extrahepatic biliary atresia associated with cyanotic congenital heart disease are presented and their clinical courses reviewed. In these patients, the coincidence of cyanosis and jaundice caused an atypical green-appearing cutaneous discoloration which masked the early clinical detection of biliary atresia in one infant and cyanotic(More)
