Calculus anuria is a catastrophic condition with dire consequences if not treated promptly. The purpose of this study was to identify factors which in uence the short-term outcome of patients with calculus anuria. A retrospective analysis was conducted from January 2016 to December 2021, in children up to the age of 18 years, who presented with calculus anuria and required emergency decompression at Sindh Institute of Urology and Transplantation, Pakistan. One hundred and twenty-ve children were included. Majority were born to consanguineous parents and a few of them had positive family history of stone disease. Severe illness was found in 25 (20%) patients and among them 8 (32%) required hemodialysis. Decompression by double J stenting is the preferred intervention in our institute and was done in 106 (85%) of children followed by Percutaneous nephrostomy tube in 10 (8%) successfully. A small number of patients, 9 (7%) required both procedures to relieve their obstruction. A signi cant number of patients, about 115 (92%), attained normal renal functions after intervention. No pertinent factors were identi ed, relating to incomplete renal recovery in 9 (7%) of patients who unfortunately progressed to chronic kidney disease.
Primary Versus Deferred Ureteroscopy for Management of Calculus Anuria in Children: Review Article
The Egyptian Journal of Hospital Medicine, 2022
Background: The incidence of urolithiasis in the pediatric population is on the rise. Urolithiasis in the pediatric age group, although occurring less in adults, causes considerable morbidity. The role of ureteroscopy (URS) in the management of calculus anuria could be primary or deferred. The deferred URS after initial ureteral stenting or percutaneous drainage is the standard one. However, the remarkable progress in the manufacturing of ureteroscopes and lithotripters favored the primary URS. Objective: This study aimed to evaluate the results of primary versus deferred URS for management of obstructive calculus anuria (OCA) in children in previous literatures. Methods: We have searched literature in the American National Center for Biotechnology Information (NCBI), PubMed, Google scholar, Egyptian bank of knowledge, and science direct. Conclusion: Primary URS is a definitive stone management technique and an appropriate option that can reduce hospital stay, prevent multiple anesthesia, and alleviate the costs in children with OCA when performed by skilled endourologists. However the deferred URS is a favored procedure for management of calculus anuria in pediatric patients compared to primary URS.
Purpose: To study the epidemiology and treatment modalities of urolithiasis at Urology Department of University Hospital of Cotonou. Materials and Methods: It was a retrospective and descriptive study over a 10 years period ranging from January 1st, 2004 to December 31st, 2013. One hundred and two patients who were hospitalized for symptomatic urolithiasis at the Urology Department of University Hospital of Cotonou were enrolled. Results: Hospital incidence of urolithiasis was 3.7%. Patients mean age was 39.6 years (extremes: 10 years to 73 years). Male to female ratio was 2.2. The main reason for consultation was renal colic for 81 patients (79.4%). Average duration of symptoms at presentation was 5 months (range: 1 day to 10 years). A total of 173 stones were identified with an average size of 12 mm (range: 1 mm to 95 mm). Calyceal stones were seen in 32.9% of cases, renal pelvis stones in 21.4% of cases, ureteral stones in 34.1% and bladder stones in 11.5% of cases. Open surgery was the main treatment for stones that could not be managed medically. 50.8% of patients underwent surgery with extraction of 116 stones. This represented 67.1% of all stones. 9 patients (8.8%) had expelled their stone during urination. The postoperative course was uneventful in 77.5% of cases. Conclusion: Modern treatment options for urolithiasis remain rudimentary in our health facilities. Open surgery is still the main stay of treatment in our countries with limited resources.
Biochemical Analysis of Stones in Cases of Urinary Tract Calculus
International Journal of Medical and Biomedical Studies, 2021
Background & Method: The present study was conducted at Department of General Surgery, Index Medical College, Hospital & Research Center, Indore (M.P.). A total of 30 study subjects (post operated cases of urolithiasis) were selected from the surgical ward in Index Hospital from period of 12 months with an aim to Biochemical Analysis of Stones in cases of Urinary Tract Calculus. Result: A total of 46 renal stones were analyzed, from 30 patients. In 30 patients, 18 were Males and 12 Females. The Bio-chemical analysis of renal stones revealed the presence of mixed stones with highest present of Calcium Oxalate stones, followed by uric acid stones. Conclusion: This study demonstrated that in Index Medical College and Hospital a significant proportion of renal stones were containing calcium oxalate as constituent and were non phosphate in composition. The study concluded that the biochemical composition of renal calculi is important during the treatment of renal stone disease and reduci...
Urinary lithiasis: diagnostic investigation
Revista da Associação Médica Brasileira
The information provided through this project must be assessed and criticized by the physician responsible for the conduct that will be adopted, depending on the conditions and the clinical status of each patient. Urolithiasis is a disease prevalent worldwide that affects approximately 15% of the world population. We performed a systematic review of the literature, with no time restrictions, in the Medline database, using the PICO methodology (patients with ureterolithiasis, pregnant, imaging exams, ESWT, radiography, ultrasonography, MRI, computed tomography, sensitivity, specificity, and accuracy, benefit, damage). We selected 18 papers to answer the questions clinics. The details of the methodology and the results of this guideline are set out in Annex 1.
Patternof Urinary Calculi ata Tertiary Hospital inSubsaharanAfrica
2017
Background: Urolithiasis is stone formation in the urinary tract which can be removed surgically to relieve symptoms or passed spontaneously in urine. They are sent to the laboratory for analyses, because knowledge of the chemical composition of stones aids appropriate treatment in order to prevent reoccurrence. We therefore aimed to determine the chemical composition of urinary calculi in our patients. Method: This was a retrospective study of the chemical composition of urinary calculi submitted to the Chemical Pathology laboratory at University of Nigeria Teaching Hospital, Enugu over a four year period. After conducting physical examination of the calculi received in the laboratory, a portion was crushed and analyzed using flame and chemical reagents. Results: Forty-fivestones were obtained from 37(82%) males and 8 (18%) females of which 37(82%) were adults and 8 (18%) children. Calculi were obtained from the following anatomic sites: Kidney 9(20%), Ureter 2(4.4%), Bladder 22 (4...
Characteristics of Calculi in the Urinary Tract Characteristics of Calculi in the Urinary Tract

Introduction: Elimination of stone is determined by size and its localization. Stone from the ureter in 80% of cases can be eliminated spontaneously. If the stone by its characteristics is not spontaneously eliminated, taken are further steps and therapeutic protocols to solve this problem. Material and methods: The study was prospective, open and comparative. It was conducted at the Urology Clinic Clinical Center of Sarajevo University in the period from 2007 to 2013. The study included 404 patients with urinary tract lithiasis treated by ESWL. ESWL treatment is performed on the machine Siemens Model Lithostar Multiline, which has a combined ultrasonographic and fluoroscopic display, large energy density in order to obtain optimum focus (without damaging surrounding tissue) and minimal pain that on rare occasions requires for mild sedation-sedation. Results: From a total of 404 patients included in the study there were 234 (57.92%) male and 170 (42.08%) female patients. The most co...
