Rao period of work were collected from the government hospitals, private nursing homes and diagnostic centers located within Purnia division. The data were collected with the Article History help of a carefully structured questionnaire. One hundred sixty five surgically removed Received: 16.09.2018 urinary stones were collected at random from the hospitals and private nursing homes Accepted: 26.09.2018 of Purnia division.

Results revealed a gradual increase in the number of urolithiasis cases in the division over the years. District wise too, there has DOI: been a gradual rise in the cases. Male to female ratio of urolithiasis cases was found to 10.21276/sjams.2018.6.9.71 be approximately 3:1. Maximum prevalence of the disease was observed in middle age (35 to 44 years) group. The months of June and July were seen to be the peak period when maximum number of cases surfaced. A predominance of the upper urinary tract calculi, particularly in males, was observed. Most of the calculi (81.8%) were found to be of mixed crystalloid composition, with calcium, oxalate and phosphate radicals, dominating. Uric acid/urate, ammonium, magnesium and carbonate were detected in rather less number of stones. Cystine was not found in any stone. Our observations in the present work would serve as a guide to the local physicians and surgeons to assess the factors behind the disease, and also to plan for combating/minimizing the incidence of urolithiasis in this region.

INTRODUCTION constituents are virtually restricted to only a few Urinary stone disease is related to a number of compounds, the slight variations might reflect the risk factors[1]. It is also a recurrent disease. Once an differences in urine biochemistry .The urine individual has had a stone, he/she has 35-50% chance biochemistry, in turn, is remotely related to the of having recurrent stone at some time later in life geographical and ecological factors of the zone. [2].The rates of urinary stone formation have also been found to vary geographically [3]. Certain geographical With the above views in mind, we have regions have been identified as endemic stone belts [1]. presently studied the prevalence of urolithiasisdisease The regional variation in the prevalence of the disease inPurnia division of Bihar (India). We have also studied as well as in the risk factors might be due to a variation the chemical composition of surgically removed urinary in the climate, water quality, food habits etc. Review of stones from the region. Purnia division is located in the literature in urolithiasis in the recent past indicates that northeastern region of Bihar province of India. This the disease is prevalent in India [4-16], as well as, in region has recently been witnessing an increasing many other countries [17-28]. In India, there is an number of urolithiasis cases [14]. In fact, we had earlier increased prevalence of the disease in the northern and conducted similar studies in this region, way back in the western regions [4-11,13,15], with some pockets period, 1999-2001. However, over the years, there have located in Kerala, Maharashtra, Tamil Nadu, Assam, been many changes in this region. Population has Manipur, Bihar and Jharkhand. increased sizeably with a parallel increase in the medical facilities. Patients earlier used to move out to Chemical composition of urinary stones from a the bigger cities for treatment.
