[The diagnosis and treatment of cystic diseases of the kidneys by using transcutaneous puncture methods under ultrasonic monitoring].

Presented in the paper are the methods of ultrasonic diagnosis and percutaneous paracentetic treatment of cystic kidneys under ultrasonic monitoring. Paracenteses were performed in 172 patients: 59 with polycystic and 113 with cystic kidneys. If the cysts located in the middle or lower segments of posterior, lateral or inferior drainage that was pushed through the guide into the cyst lumen. A thin-needle aspiration was used and the drainage avoided if the cyst located in the anterior part of middle or upper renal segments. Cystography and cystomanometry associated with the determination of the cyst tension index followed elimination of the aspirates for cyto- and bacteriological investigations. Paracentesis was accomplished under the ultrasonic monitoring of the position of a needle tip. The cavity of the cyst was sclerosed with 96% spirit in 84 patients; strong radiopaque agents were used in 8 and medicinal cyanacrylate glue in 13 patients. The drainage of the cysts with a long-term exposure to sclerosing agents (from 2 to 24 hrs) was employed in 32 patients. Postaspiration relapses were documented in all the patients with intrasinus cysts and cysts, whose major portion was surrounded by parenchyma. In the patients with other patterns of cyst location, the postaspiration relapses were noted in 94.4 per cent. A four-year follow-up of 13 patients who sustained the glue application registered 2 relapses which were successfully cured by a repeat application of the glue.(ABSTRACT TRUNCATED AT 250 WORDS)
