[Morphologic changes in the urinary bladder wall exposed to AIG-laser in the experiment].

Experiments were carried out on 20 dogs weighting 5-7 kg. Power of laser used was from two to 17 W (2; 4; 14; 17). Exposure time varied from 2 to 60 sec.

[Dynamics of structural changes of the kidneys, ureter wall, and small intestine after extensive YAG-laser destruction of the urinary bladder wall].

The experiments were carried out on 18 dogs weighted from 5 to 7 kg. The urinary bladder wall was subjected to the cauterization with laser 8 w over the period of 8 minutes. The damaged area of the opening of the right ureter consisted of 12-13 cm2.
