Objective:
We aimed to present the outcomes of patients with symptomatic kidney stones treated with percutaneous nephrolithotomy (PNL) or retrograde intrarenal surgery (RIRS).
Methods:
The medical records of patients with symptomatic renal calculi treated with PNL or RIRS between November 2010 and May 2015 were obtained. Demographic characteristics such as age; sex; BMI; stone size and location; and perioperative data including operation, fluoroscopy, and hospitalization time; and success and complication rates were assessed.
Results:
Standard (n:336), mini-PNL (n:51), ultramini-PNL (n:37) and microperc (n:47) were performed for 471 renal units. RIRS was the treatment method for 290 renal unites. In the PNL group, the mean patient age was 44.5 (1–83) years and BMI was 26.9 kg/m2. The mean stone size was 27.6 mm. In the RIRS group, the mean age and BMI were 47.1 (1–86) years and 25.1 kg/m2, respectively. The mean operation, fluoroscopy, and hospitalization times were 70.0 (20–240) min, 45.1 (17–610) s, and 2.4 (1–20) days, respectively, in the PNL group. On the other hand, the mean operation, fluoroscopy, and hospitalization times were 62.5 (40–180) min, 29.8 (0–96) s, and 26.4 (12–120) h, respectively, in the RIRS group. Whine stone free status was achieved in 88% in the PNL group; this rate was lower (80%) in the RIRS group.
Conclusion:
Both PNL and RIRS are efficient minimally invasive methods with low morbidity and high success rates for the treatment of symptomatic kidney stone disease.
