Selective minimally invasive management of calculi in patients with urinary diversions.
We evaluate the efficacy of selectively applied minimally invasive management of calculi in 30 patients with urinary diversions (ileal/jejunal conduit in 23, cutaneous ureterostomy in 2, nonrefluxing colon conduit in 4 and ureterosigmoidostomy in 1). Upper tract calculi in 38 renal units were managed with extracorporeal shock wave lithotripsy or endo-urologically. Patients were divided into 3 treatment groups determined primarily by stone size and location: group 1-25 renal units with a mean stone burden of 1.78 cm.2 treated with extracorporeal shock wave lithotripsy alone, group 2-7 renal units with a mean stone burden of 12.75 cm.2 treated with percutaneous nephrostolithotomy alone and group 3-6 renal units with a mean stone burden of 19.03 cm.2 treated with a combination of both procedures. Stone-free results were 92%, 100% and 67% in groups 1 to 3, respectively. Total hospital stay averaged 4.3, 11.1 and 13.7 nights, while complications occurred in 1, 3 and 2 patients, respectively. We conclude that selective application of contemporary techniques for minimally invasive management of calculi in patients with a urinary diversion can provide acceptable results, even with progressively large and complex stone burdens, and that these results will be equivalent to those achieved in patients without urinary diversion.
