Tumours of the ureter and renal pelvis treated with resection and renal autotransplantation: a study with up to 20 years of follow-up.

OBJECTIVE

To report long-term follow-up data from patients treated with resection of urothelial neoplasms of the upper urinary tract combined with autotransplantation of the kidney.

PATIENTS AND

METHODS

In a clinical and histopathological review of 23 patients who had 25 autotransplantations, they were followed for 7-20 years or until death. Nine patients had either a solitary kidney or bilateral renal pelvic tumours (group A) and 14 had a normal contralateral kidney (group B).

RESULTS

Seven operations were unsuccessful, ending in nephrectomy. Of the nine patients in group A two with high-grade renal pelvic tumours survived with no dialysis and recurrences for 127 and 238 months, respectively. Three patients required haemodialysis 0-3 times weekly for 27, 85 and 108 months, respectively. Three patients with low-grade disease developed invasive recurrences in the autotransplanted kidney after 16, 27 and 90 months, respectively, and later died from the disease. One patient died in an accident after 14 months. Of the 14 patients in group B, one developed a deeply invasive recurrence in the autotransplanted kidney after 86 months, despite frequent controls.

CONCLUSIONS

In patients with a normal contralateral kidney resection and renal autotransplantation is not indicated and might even be harmful, compared to standard nephroureterectomy. The operation might be beneficial in patients with solitary kidneys but other treatments should first be considered, including open or endoscopic resection, and nephroureterectomy and haemodialysis.
