Abstract

Objectives: The aim of our study was to compare the effects on quality of life (QoL) and stone-free rate (SFR) of percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS) in patients with renal stones 2-4cm.

Materials and methods: A total of 102 patients with renal pelvis stones were enrolled in this prospective controlled study, of which 52 were performed RIRS and 50 with PNL. The QoL was evaluated by using Short From-36 pre- and post-operatively. Also, the surgical data of all patients during and after the operations were compared between the 2 groups.

Results: The mean age, body mass index, stone size and density of the patients in the 2 groups were statistically similar (p > 0.05). The SFR of PNL and RIRS were found 94% (47/50) and 73% (38/52), respectively (p < 0.01). There were no statistically differences between operation times, minor complication rates and Short From-36 scores of the 2 groups. Hospitalization times were 1.13 ± 0.34days for RIRS and 2.9 ± 5.7days for PNL (p < 0.05). While the blood transfusion rate of PNL group was 8% (4/50), none patient was made blood transfusion in RIRS.

Conclusions: The results of our study show that the blood transfusion rates and hospitalization times of RIRS group are significantly lower than PNL for management of renal pelvis stone 2-4cm. Despite these advantages of RIRS, the SFR is significantly lower than PNL for these stones. The effects on QoL of the both interventions before and after surgery were similar.
