Percutaneous nephrolithotomy in the spinal cord injury population.
We evaluated 23 male spinal cord injury patients who underwent percutaneous nephrolithotomy for the success rate of stone removal and the incidence of operative complications. There were 18 quadriplegic and 5 paraplegic patients, and 5 had bilateral procedures. Of the kidneys 7 had staghorn calculi, 8 had pelvic and caliceal combinations, 6 had large multiple caliceal stones, 4 had large (more than 2.5 cm.) pelvic stones and 3 had pelvic stones less than 2.5 cm. Placement of a nephrostomy tube and stone extraction were performed as a single procedure with the use of general anesthesia in all but 4 patients. Our results showed that 19 of 21 compliant patients (90.4 per cent) were free of stone, with an average of 2.04 procedures per patient. A total of 47 procedures was performed, with an average operative time of 1 hour 45 minutes. Major complications were associated with 4 of the 47 procedures (8.5 per cent), and consisted of a respiratory arrest, 2 perirenal abscesses and a hydrothorax. Minor complications included fever (more than 101.5F) in 64.3 per cent and retained stones in 14.3 per cent of the kidneys operated upon, dislodged nephrostomy tubes in 12.6 per cent of the procedures (21.4 per cent of the kidneys operated upon), and anemia requiring transfusion in 17.0 per cent (8 of 47) of the procedures (27.8 per cent of the kidneys operated upon). The presence of infected stones, prior operative procedures and medical complexity of these patients make complications more frequent. Nevertheless, percutaneous nephrolithotomy is a safe and effective procedure for the spinal cord injury population.
