Bilateral single session mini-percutaneous nephrolithoripsy for bilateral nephrolithiasis

Introduction. Urolithiasis remains one of the most socially and economically significant urological conditions. Calculi may form in one or both kidneys simultaneously. The true global incidence of bilateral nephrolithiasis remains unknown, with its prevalence estimated at 12–26%. In clinical practice, bilateral nephrolithiasis is relatively common and presents challenges regarding the optimal surgical strategy and treatment stages for this patient cohort. Aim: to evaluate the effectiveness and safety of simultaneous bilateral mini-percutaneous nephrolithotripsy. Case Report. Patient A., a 50-year-old male, was urgently admitted in October 2024 to the Urology Department No. 1 at Regional Clinical Hospital No. 2 (Krasnodar) with a diagnosis of urolithiasis and bilateral renal calculi, accompanied by recurrent bilateral renal colic. Multislice computed tomography with three-dimensional reconstruction of the abdominal, retroperitoneal, and pelvic organs (unenhanced) revealed the following: a 12 mm calculus in the left kidney (density 1120 HU); an 8 mm pelvic stone (1340 HU); and a 10 mm lower calyceal stone (1220 HU) in the right kidney. The patient underwent simultaneous bilateral mini-percutaneous nephrolithotripsy. Total operative time was 46 minutes. No technical difficulties or intraoperative/postoperative complications were observed. There were no clinically significant changes in serum creatinine or hemoglobin levels. On postoperative day 1, follow-up unenhanced CT showed no residual stones. Conclusions. Single-session bilateral mini-percutaneous nephrolithotripsy may be considered a viable treatment option for bilateral nephrolithiasis. This approach helps to avoid repeated anesthesia and surgical interventions, shortens the postoperative period and rehabilitation time, and reduces the cost of inpatient care-provided patients are appropriately selected, adequately prepared preoperatively, and treated by an experienced surgical team.
