Management of ureteral obstruction in advanced testicular tumor with lymph node metastasis.

Abstract

OBJECTIVE:

Ureteral obstruction is one of the complications of testicular tumor with retroperitoneal lymph node metastasis that requires ureteral stenting for management. We elucidated the clinical courses of ureteral obstructions and changes in renal functions in patients with indwelling ureteral stenting.

METHODS:

The medical records of 56 patients who were treated for metastatic testicular tumors by chemotherapy at a single institute between 2002 and 2010 were retrospectively reviewed.

RESULTS:

Among 56 patients, 12 patients needed ureteral stenting before chemotherapy. The proportion of patients requiring ureteral stenting was significantly higher in seminoma than non-seminoma (47 and 12%, respectively, P < 0.05). The ureteral stent was removed after chemotherapy or retroperitoneal lymph node dissection in all patients, except for one patient who died of cancer during chemotherapy. At retroperitoneal lymph node dissection, ureters were spared in three patients, a partial ureterectomy was needed in one patient, and no case underwent adjunctive nephrectomy. These 11 patients presented no local and distant recurrence at median follow-up of 44 months. Ureteral stenting increased the estimated glomerular filtration rate to more than 60 ml/min before chemotherapy in all patients, but it decreased to <60 ml/min in 6 of 11 patients after chemotherapy.

CONCLUSIONS:

Ureteral obstruction due to testicular tumor was relieved after chemotherapy or retroperitoneal lymph node dissection. Ureteral stenting was effective to improve renal function before chemotherapy, although we should pay special attention to deterioration of renal function during or after chemotherapy.
