Objective: To investigate some epidemiological aspects of kidney stones in the SouthEastern European area. Materials and methods: From September 2015 to December 2015, 538 consecutive patients were treated and evaluated for reno-ureteral stones in eight departments in Bulgaria, Greece, Italy, FYR Macedonia, Romania, Serbia and Turkey. Results: The age of onset was lower in Turkey and higher in Italy. The rate of recurrent patients was higher in Romania and Serbia, while first renal stone formers were more frequent in Italy. The previous history of kidney stones, the characteristics of the stones and the dietary habits of the patients were different in different countries. In Bulgaria, Greece and Romania larger calculi from recurrent patients were more frequent. In Italy and Turkey smaller calculi from first renal stone formers were more frequent. Conclusions: The previous history of kidney stones, the characteristics of the stones and the dietary habits of the patients were different in different countries. A common dietary pattern associated with the formation of kidney stones was not observed, but each country showed different risk factors.KEY WORDS: Urolithiasis; Epidemiology; Diet.
SummaryNo conflict of interest declared.
Fluoroscopy is increasingly used to guide minimally invasive endourological procedures and optimised protocols are needed to minimise radiation exposure while achieving best treatment results. This multi-center study of radiation exposure of patients was conducted by the South-Eastern European Group for Urolithiasis Research (SEGUR), in cooperation with the International Atomic Energy Agency. Seven clinical centers from the SEGUR group collected data for 325 procedures performed within a three-months period, including standard percutaneous nephrolithotomy (PCNL), mini PCNL, retrograde intrarenal surgery (RIRS), semirigid ureterorenoscopy (URS) and flexible URS. Data included: air kerma area product (P
KA), air kerma at the patient entrance reference point (K
a,r), fluoroscopy time (FT), number of radiographic images (N) and fluoroscopy pulse rate, as well as total procedure duration, size and location of stones. Data were centrally analysed and statistically compared. Median P
KA values per center varied 2-fold for RIRS (0.80–1.79 Gy cm2), 7.1 fold for mini-PCNL (1.39–9.90 Gy cm2), 7.3 fold for PCNL (2.40–17.50 Gy cm2), 19 fold (0.13–2.51 Gy cm2) for semi-rigid URS and 29-fold for flexible URS (0.10–2.90 Gy cm2). Lower P
KA and K
a,r were associated with use of lower FT, N and lower fluoroscopy pulse rate. FT varied from 0.1 to 14 min, a small fraction of the total procedure time, ranging from 10 to 225 min. Higher N was associated with higher P
KA and K
a,r. Higher median P
KA in PCNL was associated with the use of supine compared to prone position. No correlation was found between the concrement size and procedure duration, FT, P
KA or K
a,r. Dose values for RIRS were significantly lower compared to PCNL. The maximum K
a,r value of 377 mGy was under the threshold for radiation induced skin erythema. The study demonstrated a potential for patient dose reduction by lowering FT and N, using pulsed fluoroscopy and beam collimation.
Objective: To evaluate spectrum and resistance rates to antibacterial agents in causative pathogens of bacterial prostatitis in patients from Southern Europe, the Middle East, and Africa. Materials: 1027 isolates from cultures of urine or expressed prostatic secretion, post-massage urine or seminal fluid, or urethral samples were considered. Results: Escherichia coli (32%) and Enterococcus spp. (21%) were the most common isolates. Other Gram-negative, Gram-positive, and atypical pathogens accounted for 22%, 20%, and 5%, respectively. Resistance was <15% for piperacillin/tazobactam and carbapenems (both Gram-negative and -positive pathogens); <5% for glycopeptides against Gram-positive; 7%, 14%, and 20% for aminoglycosides, fosfomycin, and macrolides against Gram-negative pathogens, respectively; 10% for amoxicillin/clavulanate against Gram-positive pathogens; <20% for cephalosporins and fluoroquinolones against to Gram-negative pathogens (higher against Gram-positive pathogens); none for macrolides against atypical pathogens, but 20% and 27% for fluoroquinolones and tetracyclines. In West Africa, the resistance rates were generally higher, although the highest rates for ampicillin, cephalosporins, and fluoroquinolones were observed in the Gulf area. Lower rates were observed in Southeastern Europe. Conclusions: Resistance to antibiotics is a health problem requiring local health authorities to combat this phenomenon. Knowledge of the spectrum of pathogens and antibiotic resistance rates is crucial to assess local guidelines for the treatment of prostatitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
