Staghorn calculi: endourologic management in 120 patients.

Staghorn calculi: endourologic management in 120 patients. Symptomatic staghorn renal calculi were removed from 106 of 124 kidneys (85%) with percutaneous ultrasonic lithotripsy. All remaining fragments were less than 5 mm in greatest diameter, small enough to pass spontaneously. Use of two or more access routes was necessary in 91 kidneys (73%), and 29 patients (24%) required multistage nephrolithotripsy for complete stone removal. The total operative time averaged 162 minutes per patient. The average hospitalization period was 12.5 days, and the average convalescence time after discharge was 15 days. The most common adverse effect was bleeding necessitating transfusion (57%). Infection occurred in 27% of patients and may be intrinsic to removal of these infected stones. There was one death in the study group: a patient with multiple medical problems died of myocardial infarction. Successful stone extraction requires a clear understanding of renal anatomic features, properly placed access routes, and radiologic-urologic expertise. It is concluded that staghorn calculi can be safely and effectively treated with the use of percutaneous techniques. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Radiology Radiological Society of North America, Inc.

Abstract

Symptomatic staghorn renal calculi were removed from 106 of 124 kidneys (85%) with percutaneous ultrasonic lithotripsy. All remaining fragments were less than 5 mm in greatest diameter, small enough to pass spontaneously. Use of two or more access routes was necessary in 91 kidneys (73%), and 29 patients (24%) required multistage nephrolithotripsy for complete stone removal. The total operative time averaged 162 minutes per patient. The average hospitalization period was 12.5 days, and the average convalescence time after discharge was 15 days. The most common adverse effect was bleeding necessitating transfusion (57%). Infection occurred in 27% of patients and may be intrinsic to removal of these infected stones. There was one death in the study group: a patient with multiple medical problems died of myocardial infarction. Successful stone extraction requires a clear understanding of renal anatomic features, properly placed access routes, and radiologic-urologic expertise. It is concluded that staghorn calculi can be safely and effectively treated with the use of percutaneous techniques.
