[Spontaneous rupture of renal parenchyma caused by renal pelvic and ureteral cancer: a case report].
Two cases of spontaneous rupture of the renal parenchyma caused by the renal pelvic and the ureteral cancer are reported. Case 1 was in a 53-year-old male who had left flank pain 2 weeks before admission to the hospital. In retrograde pyelography, the left upper ureter was visualized irregularly, but the left pelvis was not visualized. Computed tomography (CT) and magnetic resonance imaging (MRI) showed perirenal hematoma. Left nephroureterectomy with bladder cuff was performed under diagnosis of left renal pelvic and ureteral cancer. The rupture of the left renal parenchyma with extracapsular hematoma was identified. Pathological diagnosis was transitional cell carcinoma, grade 2 and pT1 of the left renal pelvis and the left ureter. Case 2 was in a 57-year-old male who had left flank pain 2 hours after he had enhanced CT study. MRI showed the left pelvic and the ureteral cancer with perirenal hematoma after 4 days. Left nephrourererctomy and partial cystectomy were performed. The rupture of the renal parenchyma with subcapsular hematoma was identified. Pathological diagnosis was transitional cell carcinoma, grade 2 and pT1 of the left renal pelvis and the left ureter.
