RESUMO
An endoscopical method of treating solitary renal cysts (RC) > 5 cm in diameter has been used in the Research Institute of Urology since 1989. The method implies percutaneous puncture of the cyst controlled by x-ray television or ultrasound, dilatation of the cystostomy fistula, cystoscopy followed by resection or dissection of the cyst wall with a cold knife or electrosurgically. A total of 38 patients with large solitary cysts have been treated. A 6-12-month follow-up revealed no recurrences. Complications of the surgery were not reported. The method is easy to accomplish, effective and well tolerated.

In renal disease, therapeutic procedures performed by radiologists include embolisation, cystography with obliteration and percutaneous nephrostomy. More than 72 therapeutic occlusions of the renal artery by balloon, coil, and gelfoam are presented. Basic differences in technique of application and in the mechanism of Ethibloc in comparison to other kinds of embolisation material are pointed out. In 61 diagnostic punctures of renal cysts, guided by sonograpny, 31 were treated by injection of Lipiodol. As in cystography, the combination of sonography and radiology proved to be highly valuable in 37 percutaneous nephrostomies. Technique, indication, contraindication, and complication of renal embolisation, renal cystography and percutaneous nephrostomy are briefly discussed.
