ABSTRACT
Urinary lithiases have been a major urological problem. The objective was to determine the out come of treatment for patients with calculus anuria. A descriptive study was conducted at Department of Urology Chandka Medical College Hospital, Larkana from March 2007 to April 2009. All patients with a diagnosis of calculus anuria of all ages and either sex were included in the study. Detailed history, physical examination and examination of genitourinary tract was performed. Investigations included complete blood examination, blood urea, serum creatinine, ultrasonography of KUB area, and X-Ray KUB. Among the 66 patients the cause of anuria was bilateral obstruction by the calculi in 46 cases, unilateral obstruction with small/absent/nephrectomised contralateral kidney in 20 cases. In most of the cases, ureteric catheterisation was done to relieve the obstruction. Five deaths were observed, despite emergency urinary diversion and appropriate treatment. Calculus anuria is a urological emergency. Prompt and early intervention can save the life of patient and prevent to develop chronic renal failure

Background: Hemolytic-uremic syndrome (HUS) is characterized by acute renal failure, microangiopathic hemolytic anemia and thrombocytopenia. Aim: To describe the characteñstics ofpatients with the diagnosis ofHUS in Chile, and to identify the most reliable early predictors oímorbidity and moñality. Material and methods: The clinical records ofpatients with HUS aged less than 15 years, attended between January 1990 and December 2003 in 15 hospitals, were reviewed. Demographic, clinical, biochemical, hematological parameters, morbidity and mortality were analyzed. Results: A cohort of 587 patients aged 2 to 8 years, 48 percent males, was analyzed. Ninety two percent had diarrhea. At the moment of diagnosis, anuria was observed in 39 percent of the patients, hypertension in 45 percent and seizures in 17 percent. Forty two percent required renal replacement therapy (RRT) and perítoneal dialysis was used in the majoríty of cases (78 percent). The most frequently isolated etiological agentwas Escherichia coli. Mortality rate was 2.9 percent in the acute phase of the disease and there was a positive correlation between mortality and anuria, seizures, white blood cell count (WCC) >20.000/mm³ and requirements of renal replacement therapy (p <0.05). Twelve percent of patients evolved to chronic renal failure and the risk factors during the acute phase were the need for renal replacement therapy, anuria, WCC >20.000/mm³, seizures and hypertension. Conclusions: The present study emphasizes important clinical and epidemiological aspeets ofHUSin a Chilean pediatricpopulation.

We report the first known case of anuric renal failure after same-session bilateral atraumatic flexible ureteroscopy for renal calculi. Although, there is no consensus about stenting patients who undergo same-session bilateral ureteroscopy due to the lack of prospective randomized studies; strong consideration should be given to stenting the ureter at least one side to avoid this complication.

There is little information on the management of anuria secondary to severe volume depletion or as a rare manifestation of heat stroke in areas of the world with very hot summers. We present our experience with hot weather-induced hyperuricaemia in Kuwait. Patients and Patients presenting to our urology unit as an emergency during the hot summer months of April to October [average temperature 40-55oC] were suspected of having hot weather-induced anuria secondary to hyperuricemia if they had a history of working in the sun for 6 to 8 hours per day and a progressive decrease in urine output to complete anuria. The diagnosis was confirmed by demonstration of elevated serum creatinine and uric acid, ultrasound findings of normal kidneys, ureters, and bladder [KUB] or mild to moderate hydronephrosis, but no features of chronic renal disease and little or no urine in the bladder. Management consisted of emergency cystoscopy, retrograde pyelogram, ureterorenoscopy [URS], and
