of cicatrical tissue. Healing under asepsis is per pritnam. Rubay 

 found it unnecessary to use any sutures at all, but merely returned 

 the wounded organ to its proper position. A minute scar forms 

 at the line of incision. 



After-treatment consists in dieting exclusively with milk. In- 

 creased micturition usually follows for a few days. 



NEPHRECTOMY. 



This operation is indicated in advanced cases of hydroneph- 

 rosis, or whenever the renal tissue has hopelessly lost all power of 

 function, or has sustained severe wounding. The operation must 

 not be undertaken unless the opposite kidney is perfectly healthy. 

 It is difficult where the organ is much distended, and in case of 

 cystic formation it may be found advantageous to first open the 

 sac and evacuate the contents. The pedicle is clamped with blunt 

 forceps. The renal artery and vein are then ligated. It must not 

 be forgotten that these vessels often split up into three or four 

 branches soon after leaving the aorta. Ligation is best effected by 

 means of an aneurism needle, artery and vein receiving each a 

 separate ligature. It is always safest to apply double ligatures, as 

 the risk of hemorrhage from the pedicle is very great.

CALCULI. (See also Urolithiasis). 



Urolithic deposits are seldom found in the ureters, but they 

 occasionally become lodged there in passage from the kidney to 

 the bladder, or they may form on the proximal side of the constric- 

 tion. Sutton described an instance in which a calculus was found 

 lodged in the vesical end of the left ureter, while there were two 

 large and two small ones in the bladder. Tuffier found calculi of
