RESUMEN
Repair of ureteral injury involving the distal ureter traditionally required laparotomy. Ureteroureteral anastomosis is not usually advocated due to technical difficulties and poor outcomes. Laparoscopy overcomes these difficulties and allows correction of distal ureteral injuries.

The administration of furosemide to pre-term neonates has been associated with urolithiasis. We report 1 of 2 such cases that we have managed. The etiology of these stones appears to be related to furosemide-induced hypercalciuria. Nonsurgical management with thiazide diuretics can be successful in this high risk group of patients.

A holographic technique by which two dissimilar optical fields can be subtracted to yield only their difference is presented. The principle underlying this technique is that of optical interference between a holographically reconstructed field and a direct real-time one. Experimental verification is presented for the three cases of image-plane, fourier-transform, and Fresnel side-band holograms. Also considered is the application of this concept to change detection between photographic transparencies of some scene taken at different times.
