To describe microureteroscopy, a novel minimally invasive approach for treating distal ureteral lithiasis.
Seven female patients with distal ureteral stones ≤ 10 mm were operated by microureteroscopy. The microureteroscope consist on a 4.85 Fr (16-gauge) sheath, a 0.9 mm diameter flexible optic system, and a 3-arm Luer-lock adapter to connect the sheath and insert the optics. Patients are placed in lithotomy position. Under sedative anesthesia and antimicrobial coverage, we performed microureteroscopy in patients with distal ureteral stones, describing key steps and perioperative and postoperative outcomes. Stone clearance was assessed using X-ray plain abdominal film of KUB at 15 days. Mean patients age was 54.5 years, and mean stone size was 7.98 mm. Stone-free rate was 100%. Patients were discharged 2-4 hours after the procedure without intraoperative or major perioperative complications.
Microureteroscopy was developed to reduce dilation and ureteral wall damage and, thus, to decrease postoperative stenting and hospital stay.
