Abstract:   (7149 Views)

Calculi  are   deposited  chemicals   in  compact  form . The    cause

   of  calculus  formation  is  not  known ;  however   many  physical  factors

   which  affect   the  metastable   solubility  or  insolubility  of  crystalloids  in

   complex  biological fluids are involved in the phenomenon . The majority

   of   kidney   stones   are   composed   of  one  or   more  of  the  following

   substances : calcium oxalate , calcium phosphate , uric acid , cystine ,or

   a mixture of these with magnesium ammonium phosphate. Most medical

   therapy for renal stone disease is  now based  on analysis of  calculi ; and

   decisions about proper procedures for  treatment  require  knowledge of

   stone composition.

         In this  study  267  renal calcuili were analysed.

         The commonest types  of calculus  are  calcium  oxalate   95.9%  and

   nonoxalated   calcium  97%  and  uric  acid  calculi  53.2%  or  mixture  of

   the two.

         Stone composition  is an important  guide  for the physicians decisions

   concerning investigation and a rational choice of treatment .
