[Nephrostomy of which catheter can be introduced from the abdominal wall].

AIM OF STUDY: The aim of this study is to find out the method for the nephrostomy of which catheter can be introduced from the abdominal wall.

METHODS

Subjects were the 7 patients whose agreement for this new method could be obtained. After the general nephrostomy was performed, 3 cm skin incision to the outer portion of nephrostomy, as well as 5 mm skin incision to the abdominal wall were added, and the subcutaneous tunnel between the both skin incisions was made using the special tunneler. A guide wire was introduced into the renal pelvis through the subcutaneous tunnel, and then 14 F Maleocot catheter was introduced from the abdominal skin incision to the renal pelvis. At the skin incision of the nephrostomy, catheter and subcutaneous tissue were fixed using 3-0 cutgut suture to prevent the outcomming of the catheter.

RESULTS

In case 1 to case 4 showed some trouble, but case 5 to 7 showed no trouble. The operation time and the extent of invasion of our method were as well as that of the general nephrostomy, but the managements by the patients were as simple as that of the ureterocutaneostomy.

CONCLUSION

The quality of our patients seem to close to that of uretero-cutaneostomy. And for the patients who have hydronephrosis after several type of urinary diversions, our method should be recommendable than the general nephrostomy.
