RIRS for Treatment of Stones in Congenital Anomalous Kidneys

In current stone guidelines, the recommendations for stone therapy in the kidneys with normal anatomy are clearly stated; however, there is also no clear suggestion and treatment modality in regards to the stone treatment in anomalous kidneys. Nowadays, open surgery, percutaneous nephrolithotomy (PNL), SWL, and RIRS are used for the treatment of these kidney stones. However, there is no clear consensus on which treatment modalities should be used; each modality has its unique advantages and drawbacks. in this study, the investigators will prospectively evaluate the safety and efficacy of RIRS in treatment of stones in kidneys with rotation or position anomalies. The investigators will compare the results with a matched group of patients who were treated with SWL. The results of this study may help clarify treatment options in the management of patients with stones and renal anomalies.
