Professor Pyrah has had a long and wide experience of the surgery of calculous disease and gives us in this volume something of the wisdom that he has gained thereby, but he has also been a pioneer in the setting up of a research department largely concerned with the investigation of this complex group of disorders, so that he is able to present in terms readily intelligible to the general medical reader the results of extensive biochemical investigation in this area. There is still a technical challenge to the surgeon in the removal of renal calculi, and on this topic we are always glad to have the advice of a master craftsman but inevitably much of the interest centres on the elucidation of the causes of stone formation and its prevention. Objective To study the effects of orthosiphon extract on inhibiting renal calculus.

The sonogram of some diseases may be misdiagnose as renal calculus. It is therefore no surprise that stone has been the subject of a number of monographs by eminent urologists, but the rapid development of knowledge has made it possible for each one of these authors to produce something new. Renal calculus is one of the cause of lumbar pain, and ultrasonography is the preferential methods in diagnosis of Renal calculus. For this review, both original and review. Over the past decades, remarkable advances have been emerged in the understanding of the pathogenesis, diagnosis, and treatment of calcium kidney calculi.

The earliest major planned operations were for the removal of vesical calculus renal and ureteric calculi provided the first stimulus for the radiological investigation of the viscera, and the biochemical investigation of the causes of calculus formation has been the training ground for surgeons interested in metabolic disorders. The pathophysiology of urinary stone formation is complex, involving a combination of metabolic, genetic, and environmental factors.

Minimal fluid intake, resulting in decreased urine production and a high concentration of stone-forming salts, is a leading factor in renal calculi development. Stone in the urinary tract has fascinated the medical profession from the earliest times and has played an important part in the development of surgery. The acute treatment of kidney stones (urolithiasis) addresses pain management and focuses on the effects of the morbidity associated with an obstructed renal system.
