Mirciulescu V., Multescu R., Georgescu D., Nita G., Moldoveanu C., Persu C., Dragutescu M., Ene C., Geavlete P. Emergency Clinical Saint John Hospital, Dept. of Urology, Bucharest, Romania INTRODUCTION & OBJECTIVES: Caliceal infundibular stenosis represents a rare pathology which poses certain issues regarding treatment. We evaluate the characteristics and the efficacy of the flexible ureteroscopic retrograde approach in this pathology. MATERIAL & METHODS: Between January 2012 - June 2013 5 cases with caliceal infundibular stenosis and related lithiasis were diagnosed and treated in the Department of Urology of “St. John” Clinical Hospital. A flexible Storz Flex-Xc ureteroscop was used in 4 cases and an Olympus URF-Vo ureteroscop in 1 case. In all cases was used an Ho-YAG lithotripsy. RESULTS: In 4 cases stenosis was located in superior caliceal infundibulum and in one case in the middle caliceal infundibulum. A type D coraliform lithiasis was diagnosed in 3 cases, multiple calculi in one case and a single 1cm stone in one case. A successful intervention was defined by: a good recalibration of the stenosis, lithotripsy with complete removal of stone fragments or remaining stone fragments under 2mm diameter. A reintervention was needed only in the multiple calculi case. A double JJ stent with superior loop was placed in the respective caliceal infundibulum for 4 weeks in all cases. No major complications occurred. All patients remained stone-free during followup. Restenosis of the caliceal infundibulum occurred in one case after 4 months, requiring reintervention. CONCLUSIONS: Flexible ureteroscopic retrograde approach represents an efficient treatment option in caliceal infundibular stenosis with related lithiasis. The method is associated with low morbidity and allows solving both pathologies.
