Purpose: Urinary sepsis is the leading cause of mortality in the setting of endourological procedures for stone treatment such as URS and PCNL; renal stones themselves may be a source of infection. Aim of this study is to determine the diagnostic accuracy of stone cultures (SC) collected during URS and PCNL in predicting post-operative septic complications, compared to preoperative bladder urine culture (BUC). Methods: We performed a systematic review (SR) of literature according to the PRISMA guidelines; Literature quality was evaluated according to The Risk Of Bias In Non-randomized Studies-of Interventions (ROBINS-I) assessment tool. A univariate meta-analysis (MA) was used to estimate pooled log odds ratio of BUC and SC, respectively. Results: Overall, 14 studies including 3646 patients met the inclusion criteria. Eight studies reported data from PCNL only; three from URS only; three from both URS and PCNL. Stone cultures showed a higher sensitivity (0.52 vs 0.32) and higher positive predictive value (0.28 vs 0.21) in predicting post-operative sepsis, compared to bladder urine cultures. The pool-weighted logarithmic odd risk (LOR) for BUC was 2.30 (95% CI 1.51-3.49, p < 0.001); the LOR for stone cultures (SC) in predicting post-operative sepsis was 5.79 (95% CI 3.58-9.38, p < 0.001). Conclusion: The evidence from this SR and MA suggests that intraoperative SC from stone fragments retrieved during endourological procedures are better predictors of the likelihood of occurrence of post-operative sepsis compared to pre-operative BUC. Therefore, SC should be a standard of care in patients undergoing endourological interventions.

Abstract

Purpose: Urinary sepsis is the leading cause of mortality in the setting of endourological procedures for stone treatment such as URS and PCNL; renal stones themselves may be a source of infection. Aim of this study is to determine the diagnostic accuracy of stone cultures (SC) collected during URS and PCNL in predicting post-operative septic complications, compared to preoperative bladder urine culture (BUC). Methods: We performed a systematic review (SR) of literature according to the PRISMA guidelines; Literature quality was evaluated according to The Risk Of Bias In Non-randomized Studies-of Interventions (ROBINS-I) assessment tool. A univariate meta-analysis (MA) was used to estimate pooled log odds ratio of BUC and SC, respectively. Results: Overall, 14 studies including 3646 patients met the inclusion criteria. Eight studies reported data from PCNL only; three from URS only; three from both URS and PCNL. Stone cultures showed a higher sensitivity (0.52 vs 0.32) and higher positive predictive value (0.28 vs 0.21) in predicting post-operative sepsis, compared to bladder urine cultures. The pool-weighted logarithmic odd risk (LOR) for BUC was 2.30 (95% CI 1.51-3.49, p < 0.001); the LOR for stone cultures (SC) in predicting post-operative sepsis was 5.79 (95% CI 3.58-9.38, p < 0.001). Conclusion: The evidence from this SR and MA suggests that intraoperative SC from stone fragments retrieved during endourological procedures are better predictors of the likelihood of occurrence of post-operative sepsis compared to pre-operative BUC. Therefore, SC should be a standard of care in patients undergoing endourological interventions.
