ABSTRACT

Introduction and Objectives: An ileal conduit (IC) is an established option for urinary diversion, despite the fact that early renal impairment (RI) sometimes occurs after surgery. The aim of this study was to investigate the incidence and risk factors of early RI.Materials and Methods: Thirty-one patients diagnosed with muscle-invasive bladder cancer who underwent RC with IC were analyzed in this study. Early RI was defined as a greater than 25% decrease in estimated glomerular filtration rate (eGFR) over the course of one year after surgery. The incidence and risk factors of early RI were evaluated.Results: The mean preoperative eGFR of the patients was 69.6 mL/min/1.73 m2. Early RI was observed in 7 (22.5%) patients. Multivariate analyses demonstrated that postoperative hydronephrosis was an independent risk factor for early RI (P=0.018). The mean intermediate-term eGFR change was −5.1 mL/min/1.73 m2 in patients with early RI and was greater than that (−2.9) in patients without early RI, although neither were statistically significantly different.Conclusion: Renal function after RC with IC decreased immediately over the course of one year, and postoperative hydronephrosis was an independent risk factor for early RI. Renal function had decreased slightly at intermediate-term follow-up with or without early RI.

ABSTRACT

Renal angiomyolipoma without local invasion is usually considered benign entity, however, it may extend into the renal vein or the inferior vena cava. Renal angiomyolipoma with venous extension should be treated; however, surgical complications such as iatrogenic pulmonary fat embolism remain a serious concern. We present a case of a 66-year-old Japanese woman without tuberous sclerosis in whom a right-sided renal tumor was incidentally detected on ultrasonography during a health check-up. Further evaluation showed that the tumor extended into the renal vein, and she was successfully treated using preoperative inferior vena cava filter placement and radical nephrectomy. An inferior vena cava filter can prevent catastrophic pulmonary fat embolism during nephrectomy.
