Novel porcine model for calcium oxalate stone formation.

Background: Mechanisms for calcium-based stone formation are not clearly delineated. Porcine are the most anatomically and physiologically congruent mammal to humans. Our objectives were to develop a cost-effective and easily reproducible porcine model for the study of calcium-based nephrolithiasis.

The clinical usefulness of nuclear matrix protein-22 in patients with end-stage renal disease and microscopic hematuria.

Objectives: To evaluate the sensitivity, specificity, and false-positive rate of the nuclear matrix protein-22 (NMP22) test in patients with end-stage renal disease (ESRD) and microscopic hematuria in order to avoid unnecessary follow-up tests for patients with false-positive NMP22 test results.

Patients And Methods: Patients with ESRD were screened for microscopic hematuria as part of the pre-transplant workup. Patients with documented microscopic hematuria underwent workup as recommended by the American Urological Association.

Total and partial urogenital mobilization: focus on urinary continence.

Purpose: Total and partial urogenital mobilization procedures are the most common contemporary vaginoplasty surgeries for patients with congenital adrenal hyperplasia, urogenital sinus and cloacal anomalies. There is controversy regarding the urinary continence outcomes of these procedures. We reviewed the urinary continence outcomes of children who underwent total or partial urogenital mobilization at our institution and reviewed the literature to determine the continence rates of these procedures.
