[Prevalence of renal insufficiency in individuals with obesity].

Introduction: The association of obesity with renal function disorders has been demonstrated by some studies.

Objective: The aim of this study was to assess the prevalence of renal insufficiency (RI), measured as glomerular filtration rate (GFR) < 60 ml/min and impact of weight loss on kidney function in a cohort of 109 obese patients (body mass index - BMI > 25 kg/m2), without previous kidney disease, and who underwent the dietician's treatment.

Methods: According to body mass index (BMI), the patients were classified as overweight (25-29.

[Extracorporeal shock wave lithotripsy in the urinary tract in patients with one kidney].

Extracorporeal Shock Waves Lithotripsy (ESWL) is a method of choice in the treatment of lithiasis. Surgical treatment is reduced to minimum, which in our case means 1-2%. Contraindications for using this method are: blood coagulation disorders, manifest tuberculosis, pregnancy, overobesity.

[Dynamic scintigraphy of the kidney using 99m-Tc-DTPA before and after extracorporeal shock wave lithotripsy].

The results of dynamic scintigraphy of the kidneys using 99mTc-DTPA that is glomerular radiopharmaceutic in patients before and after ESWL (extracorporeal shock wave lithotripsy) are presented. Investigation was performed in 22 patients--in 8 patients immediately before ESWL, 7 days and 3 months later, and in 14 patients before and 7 days after ESWL. The time alteration of the achievement of the maximal values of radiorenographic curve obtained by dynamic scintigraphy (Tmax), as the alteration of separate clearance (SCI) counted as an integral below the other phase of renographic curve.

[Extracorporeal shock wave lithotripsy: prophylaxis, complications and therapy].

ESWL has proved to be a safe and effective method in the treatment of urinary tract calculosis. The method is hardly invasive when compared to all other methods known so far, except for the treatment of calculosis with a selective pharmacotherapy. Moreover, the method is contactless, extracorporeal, mostly necessitating no anaesthesia and spasmoanalgesic therapy, except in the very small number of patients.
