ABSTRACT
A simple method for percutaneous insertion of nephrostomy tubes is described. In our series of 47 patients there have been no failed attempts at nephrostomy placement, and only one complication, transient septicemia, was noted. Catheter care is described, and use of the nephrostomy tract for various urologic problems is discussed.

Percutaneous drainage has rapidly become the initial procedure of choice in the treatment of most intra-abdominal abscesses. The retroperitoneal location of the urinary tract facilitates a percutaneous approach and has been found to be highly effective, with surgical intervention required in a minority of cases. Noninfected fluid collections, particularly those related to ureteral or renal pelvic injuries, may also be managed nonsurgically using percutaneous techniques, such as nephrostomy and antegrade stenting.

Renal angiomyolipomas are benign tumors which occur commonly in association with tuberous sclerosis or as isolated lesions. Symptomatic angiomyolipomas, particularly those in patients with tuberous sclerosis, should be approached conservatively with the goal of preserving as much normal renal tissue as possible. We report 2 patients in whom selective embolization was used to achieve this goal.

Intravenous digital subtraction angiography (DSA) was used to evaluate 22 patients with Leriche syndrome. The technique successfully demonstrated both the level of obstruction and the reconstitution of arterial flow to the lower extremities. In view of the relative safety of DSA, compared with the axillary approach in standard angiography, the authors believe that it should be the initial procedure for presurgical evaluation of Leriche syndrome.
