Abstract

Background

Observation, medication, or procedures that are invasive, such as percutaneous nephrolithotomy (PCNL), ureteroscopy, or even laparoscopic surgeries for instances that are severe, are among the management protocols for kidney stones. Body mass index (BMI) has a variable effect on PCNL outcome, despite obesity being linked to higher rates of perioperative complications and all-cause mortality.

Objectives- The study was conducted to evaluate the effect of BMI on renal outcomes following PCNL.

Materials and methods

It was a cross-sectional study. The study was carried out at the Department of Urology, Mahatma Gandhi Medical College and Research Institute, Puducherry, India. The study was conducted for one and a half years, that is, from October 2022 to April 2024. In all, 40 patients were enrolled.

Results

In comparison to the normal BMI group, which had a mean serum creatinine level of 1.13 ± 0.40 mg/dL, the increased BMI group had a slightly higher mean level of 1.22 ± 0.49 mg/dL. Thirty-five (97.2%) patients in the normal BMI group exhibited normal echogenicity, whereas three (75%) of the participants in the increased BMI group did the same.

Conclusion

Patients with elevated BMI had slightly higher serum creatinine levels, higher resistive index values, and a lower incidence of normal renal echogenicity, suggesting early morphological changes, even though overall renal function and vascular resistance stayed within normal limits in both groups.

Recommendation

Patients with elevated BMI undergoing percutaneous nephrolithotomy (PCNL) should be closely monitored for early renal morphological changes and subtle functional alterations to prevent long-term renal complications.
