OBJECTIVE To review our experience with retrograde intrarenal surgery (RIRS) for management of conditions associated with intrarenal stricture and present a treatment algorithm based on the series. METHODS RIRS was offered to all patients with symptomatic intrarenal stenosis regardless of location if stone burden was 2 cm or less. With a combined endourology and lithotripsy table, patients with stones between 2 and 3 cm were also offered RIRS using a combined approach of RIRS and shockwave lithotripsy (SWL). A total of 108 patients with symptomatic stones and caliceal diverticulum or infundibular stenosis were included in the data analysis. A standard technique was used in all cases. Failures or patients not suitable for RIRS were treated with either percutaneous nephrolithotomy (PCNL) or laparoscopic surgery. RESULTS Successful identification and dilation/incision of the stenotic opening was accomplished in 94% of cases. Seventy-five percent of stones were managed with basketing and/or holmium laser ablation. In these patients, 90% were stone free (<2 mm stone fragments). For stones between 2 and 3 cm, the use of holmium laser in combination with SWL provided stone-free rates of 75%. Five percent of patients needed PCNL because of larger stone burden and posterior location. CONCLUSIONS With the appropriate equipment, RIRS provides a valid treatment option for patients with intrarenal strictures. While upper pole and midrenal lesions are ideal, lower pole segments may be approached as well. A treatment algorithm based on the results provides a simplified approach for the minimally invasive management of intrarenal stenosis.
