Percutaneous Approach for Difficult Stones

Abstract

We would like to present the case of a 65-year-old man who underwent a radical cystoprostatectomy plus ureterosigmoidostomy (Mainz Pouch II) in 1996, due to a high-grade invasive transitional cell carcinoma of the bladder. He had an uneventful postoperative period and was free of disease in his 2-year follow-up visit (1998). Clinically, he had total control over his anal voiding, with no diurnal or nocturnal urine leakage. However, 2 years after surgery his intravenous pyelogram showed a stenosis of the left ureterosigmoidal anastomosis, and sonography revealedmild to moderate ureterohydronephrosis. He also had an obstructive 1-cm left renal pelvic stone.
