Abstrakt: Objective: To compare the demographics and the results of patients who underwent percutaneous nephrolithotomy (PCNL) with solitary and bilateral kidneys.
Materials and Methods: Between January 1998 and August 2014, 2268 patients underwent PCNL at Hacettepe University Hospital. We retrospectively analyzed the data of 91 patients with a solitary kidney and 2177 patients with bilateral kidneys treated by PCNL. We compared the success and complication rates between patients with solitary and bilateral kidneys. Additionally, we determined the factors affecting success and serious complications for patients with a solitary kidney. All statistical analyses were performed using SPSS 17.0 for Windows. The threshold for statistical significance was set at P <.05.
Results: The median age was 48 years and 61 patients (67%) were male. The median stone burden was 400 mm 2 . The stones were located in the renal pelvis in 27 patients (30%), in calices in 50 patients (55%), and in the staghorn in 14 patients (15%). A total of 57 patients (62%) underwent a left-side surgery. The comparison between solitary and nonsolitary patients showed that stone free, transfusion, and postoperative urinary tissue infection rates were similar. Complication rates, postoperative JJ stent requirements, and length of hospital stay were statistically higher in patients with a solitary kidney. The presence of a staghorn stone, the stone number (single-multiple), and male gender were found to have a negative impact on success. The existence of upper-pole stones was found to be the only factor that led to serious complications (Clavien 3-4).
Conclusion: PCNL is an effective but more complicated option in patients with a solitary kidney, with stone-free rates similar to patients with bilateral kidneys.
