Abstract
Introduction: Under ideal conditions PCNL has a stone clearance rate of over 90%. However, after PCNL, 10% to 35% of patients experience a systemic inflammatory reaction, and a small proportion progresses to sepsis.
Objectives: To investigate the correlation between PBUC and intra operative SC and to assess factors associated with post PCNL SIRS.
Methodology: - A prospective cross-sectional study conducted at Tibur Anbessa Specialized Hospital, Addis Ababa University, Addis Ababa, Ethiopia, on patients undergoing PCNL from December 1, 2023, to May 30, 2024. A PBUC sample was obtained prior to surgery, the broken stone was sent for examination during the procedure, and the patient was monitored for SIRS symptoms afterward. Data were gathered through the use of a formal questionnaire.For analysis, SPSS version 26 was utilized.
Results: -The mean duration of surgery was 91.48 minutes, with a range of 30–150 minutes. In 13.6% of patients, PBUC was positive, whereas in 27.3% of patients, SC was positive. There was no positive relationship between PBUC and post PCNL SIRS.In addition, age, gender, comorbidity, preoperative level of hydronephrosis, serum creatinine, laterality of the operated side, and duration of surgery were not associated with post-PCNL SIRS. There was just a positive relationship between post-PCNL SIRS and having stones in two or more calyx, positive SC, number of tracts, number of stones, and history of recurrent UTIs, but the only independent risk factors for SIRS was numbers of tracts.
Conclusion: -In our study, the only independent risk factor for post-PCNL SIRS was the number of tracts. SC is not a predictor of post-PCNL SIRS, so we don’t recommend routine SC.
