[Urinary infection in urolithiasis patients in the Epirus district (northeastern Greece)]

The relationship between renal stones and urinary tract infection is frequent but not well-known. In this study, urinary tract infection was found in 12% of renal stone formers. It is four times more common in females than in males. Urea splitting bacteria (Proteus, Klebsiella, Staphylococcus and Pyocyaneus) lead to stone formation. They were identified in 72% of cases. Proteus was predominant and the organism most frequently found in staghorn stone formers. Other non urea-splitting bacteria (E. coli, Enterobacter, Streptococcus) were observed in 25% to 30% of cases. The percentage of the various bacteria varies according to the degree of resistance to therapy and the patients sex.

Familial cystinuria in Ioannina District (Greece). Diagnosis and treatment

The "Urocystin Test" has been used as a screening procedure for the diagnosis of the incidence of cystinuria in Ioannina District (Northwest Greece). From the 210 investigated urine samples, eight were positive and four of them were also L-cystine stone formers. All positive cases belong to two cystinuric families. The pedigree in village "Kato-Lapsista" is a genetic type of a "completely recessive cystinuria" while the other one in "Marmara" is the type of an "incompletely recessive cystinuria". All patients with L-cystine urolithiasis, except one child, were treated with the drug Thiola.
