Abstract
Background: Identifying reliable predictors of postoperative renal insufficiency (PRI) following partial or radical nephrectomy for renal cell carcinoma (RCC) is critical for optimizing perioperative management.
Methods: We systematically searched MEDLINE, Cochrane Library, and Embase up to March 20, 2025, to identify cohort studies that evaluated the association between preoperative proteinuria and PRI. We calculated pooled odds ratios (ORs) with 95% confidence intervals (CIs) using a random-effects model. Subgroup analyses were stratified by study design (prospective vs. retrospective) and surgical modality (partial vs. radical nephrectomy).
Results: Six cohort studies involving 3124 patients were included. Preoperative proteinuria was significantly associated with an increased risk of PRI (OR = 2.69, 95% CI 1.48-4.89; I2 = 67.3%). We found that retrospective studies showed a stronger association between preoperative proteinuria and PRI (OR = 3.35, 95% CI 1.71-6.56) compared to prospective studies (OR = 1.89, 95% CI 0.98-3.66). Subgroup analysis by surgical approach revealed significant risk elevation in both partial nephrectomy (OR = 2.11, 95% CI 1.34-3.33) and radical nephrectomy cohorts (OR = 5.50, 95% CI 4.31-7.02), with a notably higher effect size in the latter.
Conclusion: Preoperative proteinuria is significantly associated with an elevated risk of PRI in patients undergoing nephrectomy for renal cell carcinoma. These findings emphasize the need to incorporate proteinuria assessment into preoperative risk evaluations to improve patient counselling and perioperative management. Future high-quality prospective studies, particularly multicenter investigations with standardized protocols, are essential to confirm these associations and explore the pathophysiological mechanisms underlying proteinuria-related renal functional decline.
期刊介绍:
The Irish Journal of Medical Science is the official organ of the Royal Academy of Medicine in Ireland. Established in 1832, this quarterly journal is a contribution to medical science and an ideal forum for the younger medical/scientific professional to enter world literature and an ideal launching platform now, as in the past, for many a young research worker.
The primary role of both the Academy and IJMS is that of providing a forum for the exchange of scientific information and to promote academic discussion, so essential to scientific progress.
