Calculus anuria is a catastrophic condition with dire consequences if not treated promptly. The purpose of this study was to identify factors which influence 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-five 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 significant number of patients, about 115 (92%), attained normal renal functions after intervention. No pertinent factors were identified, relating to incomplete renal recovery in 9 (7%) of patients who unfortunately progressed to chronic kidney disease.
