PURPOSE To compare the accuracy and precision of orchidometer and ultrasonographic (US) measurements of testicular volume in a canine model. MATERIALS AND METHODS Volume measurements of 18 canine testes were obtained by using Prader and Rochester orchidometers. Testes were scanned with two linear-array US transducers with imaging frequencies of 6-13 MHz(More)
PURPOSE We assessed the usefulness of RALP in children and compared an age matched cohort undergoing OPN to RALP for safety, efficacy, operative time, blood loss, in-hospital narcotic use and LOS. MATERIALS AND METHODS We performed a retrospective case-control study from 2000 to 2004 of 33 patients undergoing RALP and 33 undergoing OPN. Average age of(More)
PURPOSE We assessed the clinical usefulness of laparoscopic retroperitoneal partial nephrectomy (LRPN) in children by comparing an age matched cohort of pediatric patients undergoing open partial nephrectomy (OPN) to those undergoing LRPN for safety, efficacy, operative time, blood loss, inpatient narcotic use and length of hospitalization. MATERIALS AND(More)
PURPOSE The safety, benefits and usefulness of laparoscopic partial nephrectomy have been demonstrated in the pediatric population. We describe our technique, and determine the safety and feasibility of robot assisted laparoscopic partial nephrectomy based on our initial experience. MATERIALS AND METHODS We retrospectively reviewed robot assisted(More)
Cultured rat bladder smooth muscle cells (SMC) were grown on collagen-coated silicone membranes and subjected to continuous cycles of stretch-relaxation. Semiquantitative RT-PCR analysis revealed a time-dependent increase in heparin-binding epidermal growth factor (EGF)-like growth factor (HB-EGF) mRNA levels after stretch, with maximal levels appearing(More)
PURPOSE Laparoscopic pyeloplasty is one of the more common robotic assisted procedures performed in children. However, data regarding long-term experience and clinical outcomes for this procedure are limited. We evaluated the long-term outcomes in a large series of patients undergoing robotic assisted laparoscopic pyeloplasty at a teaching institution, and(More)
PURPOSE We evaluated the impact of tubularized incised plate urethroplasty on primary and repeat hypospadias repair. MATERIALS AND METHODS We retrospectively reviewed the medical records of all boys who underwent hypospadias repair at our institution during a recent 3-year period. The level of the hypospadias defect, technique of repair, primary repair(More)
OBJECTIVE To assess the application and safety of transoral robotic surgery in the pediatric airway. DESIGN An institutional review board-approved study. Experimental laryngeal surgery was performed on 4 pediatric cadaver larynxes as controls. Application of robotic equipment for laryngeal surgery was attempted on 5 patients. SETTING Tertiary care(More)
PURPOSE We determined the resolution rate of vesicoureteral reflux and the factors that influence it to formulate nomograms to predict the probability of annual resolution for individual cases of reflux. MATERIALS AND METHODS We studied 2,462 children with primary vesicoureteral reflux diagnosed between 1998 and 2006. Cox proportional hazards regression(More)
PURPOSE Surgical indications for correcting adolescent varicocele include high varicocele grade and testicular hypotrophy. To our knowledge these findings have not been correlated with semen parameters to date. We examined the relationship between unilateral left varicocele grade or the testicular volume differential and semen parameters in adolescents. (More)
