Abstract

Objectives: To evaluate treatment outcomes and early changes in renal function following mini-percutaneous nephrolithotomy (mPCNL) in patients with a solitary kidney. Methods: A prospective, descriptive, longitudinal study was conducted on 41 patients with upper urinary tract stones in solitary kidneys who underwent mPCNL at Military Central Hospital 108 from January 2023 to October 2025. Results: The mean age was 59.0 ± 8.8 years. The overall stone-free rate was 87.8%. Most procedures were performed using a single percutaneous tract (70.7%). The mean operative time was 43 ± 20 minutes, and the mean postoperative hospital stay was 3.3 ± 2.5 days. Within the first 24 hours after surgery, eGFR decreased significantly (from 64 ± 18 to 57 ± 19 mL/min/1.73m²; p < 0.05), whereas serum creatinine level showed a slight but non-statistically significant increase. At 3 weeks postoperatively, renal function returned to the preoperative baseline. The overall complication rate was 17.1%, with most complications being minor (Clavien-Dindo grade I - II accounted for 12.2%). Conclusion: mPCNL is a safe and effective treatment for upper urinary tract stones in patients with a solitary kidney. Although renal function may decline slightly in the first 24 hours postoperatively, it generally recovers within 3 weeks.
