a im. The aim of this study was to evaluate the bacteriological findings and the frequency of urinary tract infections in autosomal dominant polycystic kidney disease and their impact on renal function. Methods. One hundred eighty patients with autosomal dominant polycystic kidney disease were studied from 2003 to 2008. Subjects were considered as having urinary tract infections if they had had one or more episodes of urinary infection. The antibiotic therapy for the treatment has been adapted according to the bacteriological findings. Results. Urinary tract infections were observed in 60% of our patients (108 patients), and were more frequent in women than in men. The infections were typically caused by gram negative enteric organisms. Blood culture was positive in 10%, while urine culture was negative in 40%. The episodes of isolated cyst infections (negative urine culture and absence of white blood cell casts in urinary sediment) were more frequent than those of acute or chronic pyelonephritis (urinary sediment was positive for white blood cell casts). Conclusion. We conclude that urinary tract infections are frequent in our patients with autosomal dominant polycystic kidney disease. Distinguishing between cyst infection and acute or chronic pyelonephritis is often a challenge, and the diagnosis relies mainly on clinical and bacteriological findings.

AIM:We aim to define the correlations between nephrolithiasis, hypertension, age and obesity in patients with autosomal dominant polycystic kidney disease (ADPKD) in Albania.MATERIAL AND METHODS:We included 100 patients with autosomal dominant polycystic kidney from 2011 to 2014. The patients underwent X-ray and renal ultrasonography. We performed the metabolic evaluation of blood and urine.RESULTS:The patients with renal stones had a higher level of mean systolic and diastolic blood pressure compared with patients without stones (155 ± 12 mmHg vs. 145 ± 8 mmHg, and 105 ± 0.9 mmHg vs. 92 ± 1.28 mmHg, respectively). Patients with renal stones were older (47 ± 15 vs. 38 ± 5 years), had a higher prevalence of obesity [body mass index (BMI): 28 ± 2.4 vs. 25.7 ± 0.6], had higher levels of total cholesterol level (220 ± 5 mg/dl vs. 203 ± 4 mg/dl) as well as triglyceride levels (160 ± 9 mg/dl vs. 126 ± 4 mg/dl), compared with no renal stone individuals.CONCLUSION:ADPKD patients with renal stones in our study had a higher mean level of systolic and diastolic blood pressure, BMI and cholesterol and triglycerides levels compared with individuals without renal stones.
