Introduction & Objectives

Percutaneous nephrolithotomy (PNL) and retrograde intra-renal surgery (RIRS) are performed commonly in many urology clinics and European Association of Urology guidelines recommend the both treatment options for renal stones. The aim of our study was to compare the effects on quality of life and stone free rates of PNL and RIRS in patients with renal stones between 2 and 4 cm.

Materials & Methods

Sixty-two patients who had renal stones were enrolled our study. 32 patients were performed RIRS and 30 patients were performed PNL. The life quality of all patients were evaluated by using Short From (SF)-36 preoperatively and postoperatively. Also the surgical data (operation time, blood loss, hospitalization time, etc.) of all patients during and after the operations were compared between the two groups.

Results

The mean age, BMI, stone size and density of the patients in the two groups were statistically similar (p>0.05). The stone free rates of PNL and RIRS were found 93.3% (28/30) and 75% (24/32), respectively. There were no statistically differences between operation times, minor complication rates and SF-36 scores of the two groups. Hospitalization times were 1.09 ± 0.29 day for RIRS and 2.5 ± 0.7 days for PNL (p<0.05). While the blood transfusion rate of PNL group was 6.6% (2/30), none patient was made blood transfusion in RIRS group.

Conclusions

The results of our study showed that the blood transfusion rates and hospitalization times of RIRS group were significantly lower than PNL group for management of renal stone 2-4 cm. In spite of these advantages of RIRS, the stone free rates were significantly lower than PNL for these stone. The effects on quality of life of the both interventions were similar.
