154 patients with urolithiasis and 24 normal controls were investigated for serum levels and urinary excretion of magnesium. No significant difference in urinary magnesium excretion could be found neither between stone forming patients and normal controls nor between patients with different types of stones. There was also no difference in serum concentrations of magnesium. A disturbance in excretion of magnesium in urine could not be related to increased recurrence rate of stone formation. According to these findings it is doubtful whether a disturbance in urinary excretion of magnesium plays an important role in stone formation. Therefore the determination of magnesium excretion can be neglected in the course of routine investigation of patients with urinary calculi.

The incidence of urolithiasis in Manipur is very high. From hospital records for a period of 7 years and 3 months, it was observed to be 11.6% of all general surgery cases in the General Hospital, Imphal. This is alarmingly high. The social, eating, drinking, and living habits are different among the three major populations in this state. The prevalence was minimal among Tribals. Compared to them the prevalence was about one and one half times higher among Muslims (also called Pangals) and seven times higher among Hindus. Surprisingly, the incidence of renal calcalus was higher in females. One hundred ninety-six stones were studied by wet chemical analysis. Calcium and oxalate were present in all stones. Phosphate was present in 194 stones and uric acid (including urate) was present in 146 stones.

Urolithiasis is a disease of multifactorial origin. Prominent amongst the causes of disease outbreaks are nutritional factors. Alteration of diet is probably one of the most effective means of prevention, depending of course on the nature of the uroliths formed. In this regard analysis of the stones formed is an essential prelude to understanding, adequately treating the disease and preventing its recurrence.

Vesical stones in children are the commonest stones in the Sudan. In recent years there has been a progressive increase in the number of operations for upper tract stone, suggesting a change in the pattern of urolithiasis.

Analysis of 56 cases of coralliform urolithiasis has shown, among other things, the normally poor symptomology. This is in contrast to the poor prognosis which, in the absence of treatment, almost always ends in the destruction of the kidney. Besides ten immediate nephrectomies, 52 conservative operations were performed on forty patients. These conservative operations are difficult, long and meticulous. They are greatly facilitated by using an endocavitary lighting source of cold light. The use of contact X-ray is indispensable. Removal of stones must be absolutely complete. The number and extent of the nephrotomies must be reduced to a strict minimum. One must avoid the big, destructive nephrotomies--except, perhaps, in children. With the help of all these precautions, the results are encouraging; no secondary nephrectomies until present time, only two real relapses, and three small previously-undetected calculi. Yet, thanks to the systemic use of the cold light and of the contact X-rays, there were no more "undetected" calculi for the last 4 1/2 years.

In the last 17 years, 55 of 2,125 (2.6%) purebred beagles maintained in a closed colony had urolithiasis. Males comprised 72.7% of the affected animals. All the uroliths except one set in the kidneys were in the urinary bladder, the urethra, or both. All uroliths were nearly pure magnesium ammonium phosphate hexahydrate. Partially inbred beagles had a 10.7% incidence of urolithiasis, compared to a 2.0% incidence in an outbred line.

In recent 17 years from 1959 to 1975, 32296 patients were visited to the Urological department of Hokkaido university hospital. 1192 patients (male 818, female 374) were diagnosed as urolithiasis in this period. The incidence was 3.7%. Among them, 1324 urinary calculi were seen. In detail, renal stone 509 (38.4%), ureteral stone 717 (54.2%), bladder stone 84 (6.4%), urethral stone 14 (1.1%). The tendency of upper urinary stone-wave was increasing gradually. Especially after 1965, it was increasing sharply. The tendency of lower's was stable. There was 15 urolithiasis in childhood in this duration. Most of them were upper urinary stone. 9 patients were under 5 years of age. The cause of urolithiasis was found in 9.5%. The upper urinary stone was found only 4.7% but, 57% was found in lower urinary stone. In this report, statistical studies of this work was compared and discussed with already published data in 1961 of our department.

A retrospective study of 32 adult patients undergoing ureteric reimplantation for reflux has been carried out. Reflux and reimplantation in relation to urolithiasis, pregnancy, renal failure, hypertension and bladder neck obstruction have been discussed. Eighty-four per cent of patients with primary reflux had pyelonephritic scarring compared with only 34% of patients where reflux was secondary. Reimplantation has been technically successful in preventing reflux in every patient in this series, with 18 patients (65%) becoming symptom free. Pyelonephritis, hypertension and renal failure were not significantly improved but no progressive changes were observed in the follow-up period after reimplantation.

Nine hundred and ninety-seven Sudanese patients presenting to a urological unit in Khartoum were divided into a group consisting of 144 patients with a history or evidence of urinary bilharziasis and a second group of 853 patients with no history or evidence of this disease. Thirty-one per cent of the patients with bilharziasis and 32% of those without were found to have urinary calculi. In the bilharzial group there were recurrent stones in 7% compared with 12.4% in the non-bilharzial group. In the bilharzial group the stones were renal in 63.6%, ureteric in 27.3% and vesical in 9.1%, while in the non-bilharzial group 57% were renal, 30% ureteric and 13% vesical. Comparison of the incidence, rate of recurrence and site of stones in both groups suggests that urinary bilharziasis does not contribute to the high incidence of urolithiasis in the Sudan.

Hematuria is the presence of more than 5 RBC's in repeated urinary sediments. Erythrocyturia may be present as an isolated finding or it may be associated to other clinical findings that may lead to the etiology of the hematuria. Its origin may be renal or extrarenal. In the neonate, meatal or urethral bleeding, polycystic kidney or hydronephrosis must be considered. In the infant, hematuria may be due to vascular disease, renal vein thrombosis, as well as to urinary tract infection, urinary tract obstruction or acute tubular interstitial nephritis due to drug ingestion. Primary and secondary glomerulopathies, urinary tract infection and urolithiasis are the most frequent causes of hematuria in pre-school or school-age children. The diagnostic approach emphasizes the importance of the clinical history, familial background and the circumstances of presentation. RBC casts and proteinuria may suggest the presence of a glomerulopathy. Leukocyturia is more frequent in urinary tract infections and requires urine cultures and intravenous pyelogram. In cases of isolated hematuria, blood clotting test, P. T., P.T.T., platelet count and RBC's morphology may be required to rule out hematological disorders. The intravenous pyelogram, voiding cystogram, and occasionally cystoscopy will help to rule out urological abnormalities. If the previous results were negative, the renal biopsy will help to distinguish IgA mesangiopathy, Alport's syndrome or essential hematuria; this last diagnosis resulting by exclusion.
