Use of mobile extracorporeal shock wave lithotripter: experience in a pediatric institution.

Objectives: To present our results of the past 3 years using a mobile lithotripter in a pediatric institution. The low incidence of pediatric urinary calculi, along with the high cost of lithotripsy units, has limited the use of extracorporeal shock wave lithotripsy in pediatric institutions.

Methods: A retrospective cohort study was performed of all children who had undergone extracorporeal shock wave lithotripsy at two institutions from 1999 to 2003.

Bladder calculi after augmentation cystoplasty: risk factors and prevention strategies.

Purpose: Lower urinary tract reconstruction is an essential tool in the management of severely dysfunctional bladders in children. The incidence of calculi in augmented bladders has been reported in up to 50% of cases. We analyzed our experience with stone formation in this population to assess risk factors and outcomes.

Adult testicular torsion.

Purpose: Testicular torsion in adulthood is thought to be relatively unusual. We compared a series of men 21 years old or older with testicular torsion with a concurrent series of younger patients with torsion.

Materials And Methods: We reviewed the medical records of patients admitted with testicular torsion in a 9-year period to hospitals affiliated with our institution.
