ABSTRACT

Objective: The aim of this study was to evaluate the success and complication rates of percutaneous nephrolithotomy (PNL) surgeries performed in our clinic.

Material and Methods: Between March 2011 and January 2018, patients who underwent percutaneous nephrolithotomy in Adana City Training and Research Hospital and their records were retrospectively analyzed. Routine non-contrast computed abdominal tomography, hemogram, biochemistry, urine culture, kidney ureter bladder radiography (KUB) and postoperative first month urinary culture, urinary tract X-ray and urinary ultrasound were performed. The patients were evaluated in terms of sex, age, stone localization and size, operation time, number of stones, success rates, intraoperative and postoperative complications, nephrostomy and hospital stay.

Results: In our study, 586 males and 414 females with a mean age of 45.2 ± 10.4 (1-84) were enrolled to 1183 renal units, and 1000 patients were treated with PCNL. Mean operative time was 74.2 ± 29.5 min (30-170). 462 patients had isolated pelvis and calyceal stones, 347 had partial staghorn, 44 had complete staghorn, and 147 were multiple. The success rate of the patients (stone free + clinically insignificant residual stone) was 85.3%. In the postoperative period, 114 patients (11.4%) required transfusion, 14 patients (1.4%) had arteriovenous fistula and 132 patients (13.2%) had a Double J catheter. Four (0.4%) patients had colon perforation.

Conclusion: As seen in our comprehensive series of percutaneous nephrolithotomy, success rates are high in experienced centers and complication rates are acceptable, and the operation is safe and effective.
