[Urinary electrolyte excretion in autosomal dominant polycystic kidney].

In 33 patients with autosomal dominant renal polycystosis the urine excretion of the electrolytes sodium and potassium was examined and analyzed in relation to the renal function and the arterial pressure. The clearances, the urine ratio and the excreted fractions of both electrolytes were calculated. It was established that by normal renal function and without arterial hypertension there were no significant differences in the parameters studied between the patients and the healthy controls.

[Rare complications in polycystic kidney--the difficulties in their diagnosis and treatment].

The development of some rare complications of renal polycystosis is discussed. Four patients with chronic polycystosis with complications are followed up. In 3 of them (2 of them on chroniodialysis) the cysts suppurated and after an infective conservative treatment they were treated surgically-puncture, cyst excision and unilateral nephrectomy.

[Autosomal recessive polycystic kidney].

A case of a 22 years old woman with autosomal-recessive form of kidney polycystosis is presented. The diagnosis was made in early childhood. A combination of renal anomaly and hepatic fibrosis with manifestations of portal hypertension was present.

[Chronic pyelonephritis in polycystic kidney].

The characteristics of chronic pyelonephritis are studied in 37 patients out of a total of 53 patients with proved renal polycystosis. A group of 71 patients with chronic pyelonephritis selected at random are used as a control group. The frequency of chronic pyelonephritis among the patients with renal polycystosis is 69.

[Secondary cystic changes in the kidneys in chronic kidney failure].

In patients with chronic renal failure the presence and frequency of acquired cystic changes in the kidneys (acquired cystic renal disease) were studied. 46 patients, 21 to 62 years of age and duration of hemodialysis treatment from 2 up to 126 months, were examined. The patients with polycystic kidneys were excluded.
