Ultrasound screening strategies for the diagnosis of congenital anomalies of the kidney and urinary tract.

Purpose: Congenital anomalies of the kidneys and urinary tract (CAKUT) are among the most common anomalies in newborn infants, and may cause chronic renal disease in newborns. We investigated the sensitivity and specificity of different ultrasound-based screening strategies for CAKUT.

Materials And Methods: Newborns (n = 4331) were analyzed for CAKUT in at least one ultrasound examination as a part of the Survey of Neonates in Pomerania (SNiP), a 7-year population-based study on neonates in Western Pomerania (Germany).

[Minilaparoscopy below the left costal border with radially expanding STEP-Trocar-System in patients with previous pelvic surgery--results of a pilot study].

As a part of a prospective study of 20 patients with previous pelvic surgery, the efficacy of using a 2/3 mm dilatable STEP device (InnerDyne, Inc., Sunnyvale, USA) for the first insertion in the area below the left costal border was tested, using 2 or 3.3 mm minilaparoscopes (Storz).
