Retroperitoneoscopic treatment of ureteropelvic junction obstruction

Purpose: To demonstrate feasibility and safely of retroperitoneoscopic treatment of ureteropelvic junction obstruction, Materials and methods: II patients with symptomatic ureteropelvic junction obstruction were selected for retroperitoneoscopic pyeloplasty. Operative rime ranged between 2 h 30 min and 4 h (mean 3 h 10 min), in 5 cases we had to convert to open surgery and an open pyeloplasty was performed through a minimal (6 cm) lombotomic incision, Results: Follow-up IVPs were performed in all patients approximately 2-3 weeks after stent removal. In all patients, a reduction in the grade of hydronephrosis was observed. Significant improvement mas noticed in 9 patients; in 2 patients a moderate improvement was observed. Conclusions: Our experience with retroperitoneoscopic treatment of ureteropelvic junction obstruction demonstrates that also with this approach it is possible to perform reconstructive procedures, with minimal complications. Technical refinements will progressively reduce the conversion rate to open surgery, even if done through minilaparotomy.
