ABSTRACT
An epidemiological study of urinary stone disease has been carried out in the districts of La Sierra and Hellín (Albacete, Spain). Between January 1992 and December 1999 a total of 887 patients with urinary lithiasis have been studied, analysing the number of patients discharged from hospital with the primary diagnosis of lithiasis, the distribution of lithiasis by area, age, gender, family history of lithiasis, diet, occupation and concurrent pathology. The geographical, geological, and climatic conditions, the composition of the water supply and the clinical characteristics are described. The incidence of urinary lithiasis in the whole area in 2.66 per thousand inhabitants/year, showing a male predominance with a male:female ratio of 1.26:1. The mean age was 51.34 years (bimodal distribution with peaks in the 4th and 7th decades). 20.41% of the patients had a family history, with the father being the most frequently affected relation. Those occupations associated with a sedentary life style or with a hot, dry workplace show a higher incidence of lithiasis. A hot, dry climate favours the formation of urinary lithiasis and the highest incidence of lithiasis is in the summer, during the months of July and August. No statistically significant influence was shown between at the hardness of the water and the incidence of urinary lithiasis in the study population.

Se realiza un estudio epidemiológico de la enfermedad litiásica en las comarcas de la Sierra y de Hellín (Albacete). Entre Enero de 1992 y Diciembre de 1999, se han recogido 887 pacientes con litiasis urinaria, analizando la incidencia hospitalaria, distribución de litiásicos por localidad, edad, sexo, antecedentes familiares de litiasis, dieta, profesión y patología concomitante, se describen las características geográficas, geológicas, climáticas, composición de aguas, así como las características clínicas.La incidencia de urolitiasis en esta área es de 2,66 por mil habitantes/año, de predominio en varones con una relación de hombre/mujer de 1,26, la edad media es de 51,34 años (comportamiento bimodal con picos en la cuarta y séptima décadas).El 20,41 por ciento de los pacientes tienen antecedentes familiares, siendo el padre el parentesco más afectado. Las profesiones que comportan una vida sedentaria o se relacionan en ambientes calurosos tienen una mayor incidencia de urolitiasis. Los hábitats con clima caluroso y seco favorecen la enfermedad litiásica, produciéndose la mayor incidencia de litiasis en verano durante los meses de Julio y Agosto. No apreciamos una influencia estadísticamente significativa entre la dureza de las aguas y la incidencia de litiasis urinaria en la población estudiada (AU)

The hospital mortality rate in our centre es 2.34% (264 deaths from a total of 11,336 discharges between 1991 and 1993). The most frequent causes are acute myocardial infarction and cerebrovascular accidents, followed in descending order by pneumonia, chronic bronchitis, congestive heart failure, upper GI haemorrhage, GI tumours, liver cirrhosis, lung tumours and arrhythmias. Our analysis reflects a mortality pattern of a rural population with an age pyramid in which 52% of the patients are older than 45 years. The pattern also reflects the little impact of accidents on our mortality. A 87% of the deaths were older than 65 years with a male to female ratio of 1, 6 and a Swaroop index of 93% and 94% for males and females respectively.
