Based on the literature and of their own experience, authors deal with the possibility of the percutaneous approach of renal diseases. Of the diagnostic and therapeutic interventions, they report their experience regarding percutaneous nephrolithotomic investigative methods employed in the differential diagnosis of renal masses. During a period of one-and-a-half years, percutaneous nephrostomy was performed in 130 cases, of them in 64 for removing stones. In 48 cases of renal tumours revealed to be cystous structures by ultrasonography, puncture controlled by ultrasound was made. Based on the cytological and chemical analyses of the samples obtained by puncture, exploration was made in 6 cases for suspicion of malignancy. The requirements of the application of the percutaneous technique is discussed.
