Bilateral same session ureteroscopy

During a period of 4 years we performed 15 bilateral 1-session ureteroscopic examinations in 13 patients. Indications included bilateral ureteral and/or renal calculi, unexplained hydronephrosis, hematuria or filling defects, and bilateral ureteral stent placement in situations when conventional retrograde methods of stent placement failed. Balloon or hydraulic intramural ureteral dilation was performed in all cases before rigid or flexible endoscopy. There were no major short-term or long-term complications resulting from bilateral 1-session ureteroscopy.
