Assessment of the renal collecting system using a pocket-sized ultrasound device.

Purpose: To assess the performance of a pocket-sized ultrasound device (PUD) for evaluating dilatation of the renal collecting system with high-end ultrasound devices (HUDs) as a reference standard.

Methods: One sonographer examined both kidneys using a PUD to evaluate dilatation of the collecting system. The grading of the dilatation ranged from 0 to 4.

Ultrasonography for ureteral stone detection in patients with or without caliceal dilatation.

Purpose: To evaluate the relationship between the degree of hydronephrosis and the detection rates of ureteral stones with ultrasonography (US).

Methods: Of 250 consecutive patients with suspected ureterolithiasis, 214 who were diagnosed with ureterolithiasis were enrolled in this study. First, both kidneys were observed by US to evaluate the intrarenal collecting systems.

Retinal detachment with breaks in the pars plicata of the ciliary body.

We studied four eyes with retinal detachment accompanied by a break in the nonpigmented epithelium in the pars plicata of the ciliary body in three patients with atopic dermatitis. Each eye had either ectopia lentis or coloboma of the lens. In the region of the lens malformation, ciliary processes were hypoplastic.
