Tuberous sclerosis complex results from mutations in 1 of 2 interacting gene products, hamartin or tuberin. The syndrome is characterized by hamartomas and neoplastic lesions, including angiomyolipomas the kidney other organs. Renal cell carcinoma (RCC) tuberous remains relatively poorly because historical studies were confounded inclusion epithelioid angiomyolipomas. authors present a patient with bilateral renal multiple minute angiomyolipomas, cortical cysts, 4 separate RCCs unclassified...
Previous studies have failed to fully establish whether ototoxicity is related in any way the levels of an aminoglycoside antibiotic perilymph. To study this we exposed guinea pigs continuously infused amikacin at four different dosing rates under conditions parallel those used our previous which total plasma area concentration-time curve regardless level plasma. It was found that all rates, perilymph and ratios perilymph/plasma remained constant as duration increased from nonototoxic...
Purpose: Minimally invasive approaches to the surgical management of vesicoureteric reflux (VUR) have become more prominent over last 10 years with progress in both endoscopic and laparoscopic/robotic surgery. We hypothesized that laparoscopic extravesical detrussoraphy (LED) for VUR children complex bladders and/or bilateral was safe effective. Subjects Methods: Under institutional review board approval we evaluated charts all patients seen at our institution 8 who had undergone LED VUR....
Recent comparisons of the impact surgical approach on pediatric pyeloplasty outcomes have generally incorporated a form internal ureteral drainage. We hypothesized that does not affect in children who undergo unstented and stenting offers no long-term benefit those with pyeloplasty.After receiving institutional review board approval we examined records all underwent initial from December 2001 to 2009. compared stented pyeloplasties, each group.During study period 367 pyeloplasties were...
Abdominoscrotal hydrocele is a poorly understood entity and multiple theories attempt to explain its occurrence. To our knowledge the factors contributing formation of abdominoscrotal are unknown, as cellular, biochemical hydrostatic properties. We prospectively evaluated at surgery define cause effects on testicle.Six patients (9 hydroceles) were surgery. Hydrocele volume was recorded well simultaneous bladder pressure. Fluid sent for cellular analysis. Testicular epididymal abnormalities...

Laparoscopic orchiopexy is a safe operation. However, the bladder can be injured during creation of transperitoneal tunnel for cryptorchid testis. We reviewed our experience with this complication.We searched operative notes patients who had undergone laparoscopic between August 15, 2002 and October 1, 2008, identified injuries their treatment.A total 93 underwent orchiopexies 101 undescended testes study interval, 3 procedures resulting in injuries. The operations varied regard to whether...
Parental decision making in children with vesicoureteral reflux has potentially become more complex the evolution of ethnic diversity United States, Internet, publication contradictory clinical data and emergence minimally invasive surgery. We performed a cross-sectional study parental management for pediatric reflux.We administered 26-item questionnaire to parents seen at Texas Children's Hospital urology offices or undergoing antireflux surgery that institution. Univariate multivariate...
Although approximately 15% of children will have primary monosymptomatic nocturnal enuresis (PMNE) at age 6 years, only 1% to 2% adolescents continue wetting by the late teen years. Treating PMNE involves accurate diagnosis and an in-depth understanding multiple factors that cause wet. Failure recognize causes or nonmonosymptomatic (also known as enuresis) lead treatment failure in many children.After completing this article reader should be able to:Brittany is a 9-year-old girl seen...

The time course of threshold increase in the VIII nerve compound action potential was studied guinea pigs following amikacin administration at four different constant infusion rates. Despite wide range dosing durations required to achieve drug ototoxicity (2-24 days), full development both high and low frequency hearing loss invariably found be delayed with respect removal. greatest degree generally occurred within first 7 days after removal, smaller losses occurring during later intervals....
Segmental testicular infarction is a rare entity with fewer than 40 cases documented in the literature. It frequently mimics an acute scrotum presenting pain and swelling. Difficulty distinguishing benign from malignant lesions on imaging has led to radical orchiectomy past. With improvements imaging, this condition may be treated more conservatively. We present first case of bilateral segmental discuss management options.
