Acute kidney injury in Ureteric Stones:Single centre short term analysis

OBJECTIVE: To analyze acute kidney injury (AKI) frequency, risk factors and outcome in ureteric stone patients. METHODS: This is an observational retrospective study performed in a single tertiary care centre in Abu Dhabi from October 2014 till August 2015. Convenient sampling was done on 152 consecutive patients who underwent decompression surgery (Ureterorenoscopy LASER Lithotripsy and DJ Stenting) for ureteric stones. Serum Creatinine was used to calculate creatinine clearance by cock croft Gault formula in all patients before and after procedure. Analysis was done on SPSS version 17. RESULTS: Out of 152 patients who under went decompression surgical procedure for ureteric stones AKI was seen in 49(32.2%). Patients with AKI were found to be more higher age, increasedweight, bilateral stones, lower ureteric stones and with co morbidities in comparison to those who were without acute kidney injury. Patients developing AKI, 89.7% recovered either partially(20.4 %) or completely (69.3%). CONCLUSION: AKI is seen more in ureteric stone patients with older age, increased weight, bilateral stones, lower ureteric stones and with co morbidities. Recovery is good when obstruction is relieved.
