title: [Polycystic kidneys in adults. A clinical study of 106 cases (author's transl)].
abstract: A series of 106 cases of polycystic kidneys in adults is presented. The main clinical, exploratory and therapeutic data are analyzed. The average age of the patients at the time of the first clinical manifestation was 35 years; average age at the time of diagnosis was 43 years. The most common forms of presentation included renal colics, blood hypertension, noncolic lumbar pain, macroscopic hematuria, and polydipsia-polyuria. The most frequent symptoms were: abdominal pain of any type (73 patients), polydipsia-polyuria (66 patients), blood hypertension (61 patients), macroscopic hematuria (47 cases), episodes of urinary infection (41 cases), and passing of calculi (22 cases). Seventy-eight subjects had arterial high blood pressure; it was easily controlled in all except 14 cases. Proteinuria was slight in all except two cases. Values for hematocrit and hemoglobin remained high in relation to the degree of renal insufficiency. The mean value of hematocrit in patients with creatinine clearance below 10 ml/min was 30 percent. Renal function decreased gradually, from normal to a clearance of less than 10 ml/min over a period of 12 years on the average. Diagnosis was based mainly on abdominal physical examination and intravenous urography; 89 patients had palpable abdominal masses. Urography revealed typical images of polycystic kidney in every case. The following associated conditions were also discovered: liver cysts (17 cases among 57 liver scanning; bilateral ovarian cysts in one case; Cacci-Ricci's disease in one case; and cerebral arterial aneurysms in another patient. Treatment was conservative with the aim to control arterial blood pressure and urinary infection. Twenty-nine patients required saline replacement; peritoneal dialysis was practiced in two cases and permanent hemodialysis was prescribed for 15 individuals.
