RESUMO

BACKGROUND: An increase of the frequency of uric acid urinary stones compared to calcium-containing ones has been recently described. This study was aimed at assessing the frequency of different types of urinary stones in the population of northern Italy in the period 2016-18 compared to 2001-2003. METHODS: Analyses by infrared spectroscopy of 1007 stones endoscopically removed at two institutions in the area of Milan (Northern Italy) were retrospectively considered. Stones were classified as calcium oxalate monohydrate (COM) and dihydrate (COD), mixed uric acid/calcium oxalate (UC); uric acid (UA), struvite (ST); apatite (CAP); mixed calcium oxalate / apatite (CAPOX); others. The patients were divided into two groups: 2001-2003 and 2016-2018. The average temperature values of the region over the two time periods were obtained by the national statistical institute. RESULTS: The average age of the 2001-2003 group (45.8+/- 15.4 years) was significantly lower than the average age of the 2016-18 group (57.9+/- 14.8) (0.000). M / F ratio was similar in the two groups: 119 / 69 (1,0.58) in 2001-2003 and 527 / 292 (1,0.55) in 2016-18 (p = 0.862). COM stones tended to more frequent in 2016-18 group than in 2001-03. COD stones were significantly more frequent in 2001-03 than in 2016-18. ST stone frequency was increased from 2001 to 03 to 2016-18. No increase of uric acid containing stones was observed in 2016-18. Results were confirmed after adjustment by age. Averages annual regional temperatures increased from 14 °C to 15.4 °C during the two observation periods. CONCLUSIONS: No increase of UA stones was observed, probably due to the limited impact of the global warming in our temperate climate.

RESUMO

OBJECTIVE: To investigate some epidemiological aspects of kidney stones in the South- Eastern 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.

RESUMO

INTRODUCTION: The relationship between ejaculatory frequency and ejaculatory latency time is under-investigated. SUBJECTS AND METHODS: 120 healthy subjects were enrolled in a prospective randomized trial. Patients in group A engaged in sexual intercourse after a 10-day abstinence period for 3 months. Patients in group B engaged in sexual intercourse twice a week for 3 months. Ejaculation function was evaluated through the measurement of the intravaginal ejaculatory latency time (IELT) and through the premature ejaculation diagnostic tool (PEDT) at baseline and at the end of the study. RESULTS: At the end of the study, mean IELT values in group A were significantly lower compared to baseline values. Results from the PEDT questionnaire at the end of the study demonstrated a significantly worse ejaculatory control and ability to delay ejaculation by patients in group A. CONCLUSIONS: Reduced ejaculatory frequency impairs ejaculation control.
