FOUR CASES OF SOLITARY RENAL CYST

Abstract

We saw four cases of huge solitary renal cyst which appeared different symptoms and shall report them.
1) 62 Years. _??_. After we diagnosed as bleeding of left Kidney and did intrapelvic infusion with jodnatrium solution, it caused nephropyelitis which is due to infection. The infection spreaded to one largest renal cyst of policystic kidney.
The interior fluid differs from another cyst and it is colloideal. We testified pathohistologically that it was caused by infection.
2) 72 Years. _??_. We found a huge solitary renal cyst at the moment of operation of bladder-cancer and left hydronephrosis and took out it by way of partial nephrectomy. We proved that their were urea and sugar and that their were no uriac acid, aceton and indican.
3) 27 Years. _??_. After partial nephrectomy for right double renal pelvis and double ureter, a cyst grew in it and we removed it. We proved that there were urea and that there were no sugar, indican and aceton. We can not find such a cases in reference.
4) 53 Years. _??_. We found a figure of a typical huge solitary renal cyst by pneumoretroperitoneum. At the moment of operation, we found the displacement of kidney by weight of cyst. We calculate the interior fluid of cyst by quantitative analysis and we got this result: total-nitrogen 59mg/dl, urea-nitrogen 46.1mg/dl, Cl 117mEq/l, Ca 1.8mEq/l, Na 119mEq/l, K 3.4mEq/l.
We analysed two cases of them qualitatively, calculated one case by gantitative analysis and calculated content of electrolyte of interior fluid of cyst. Three cases schow that the ingredient of interior fluid are akin to the ingredient of urine.
