Factors Affecting Retrograde Intrarenal Surgery Success: 6 Years Experience of a Clinic in Central Anatolia.

Background

Urinary system stone disease is an important health problem. It has been reported to have a prevalence of 14.8% in Turkey. The aim of the renal stone removal surgery is to clear the stones with minimal complications. Retrograde intrarenal surgery (RIRS) is a safe method due to the fewer and minor complications. As a clinic in central Anatolia, we aimed at researching the factors affecting RIRS success in our area.

Methods

After local ethics committee's approval, the data of the patients who had undergone RIRS between 2014 and 2019 were reviewed. Patients who were <18 years old, had kidney anomalies, and had both ureter and kidney stones were excluded from the study. The patients who were defined as successful were named as Group 1 and the others were named as Group 2. The demographic, intraoperative, and postoperative data of the two groups were compared.

Results

There were a total of 416 patients in our study. Group 1 consisted of 332 patients, whereas Group 2 had 84 patients. Opacity was significantly different between the groups (P = .004). Stone size, stone volume, and operation time were significantly higher in Group 2. After logistic regression analysis, we found that stone size, opacity, and operation time affected the success of RIRS significantly (P < .05). There was a reverse relationship with stone size, operation time, and opacity.

Conclusions

We believe that in patients who have large lower calix stones and who want effective treatment, percutaneous nephrolithotomy should still be an option for treatment.
