Retroperitoneoscopic partial nephrectomy using radiofrequency ablation.

Two patients with renal tumors underwent retroperitoneoscopic partial nephrectomy. The renal tumors were initially treated with radiofrequency ablation. This method allowed tumor excision to be achieved without clamping the renal pedicle. Residual renal function was well maintained as determined by enhanced computed tomography scanning and measurement of the serum creatinine level. There were no complications such as vascular damage or collecting system injury. The pathological diagnosis was clear cell carcinoma (pT1) in Patient 1 and was not determined in Patient 2 because of entire ablation. No recurrence has been observed after 3 years and 2 years of follow up, respectively. Radiofrequency ablation was useful for control of local bleeding during retroperitonaoscopic partial nephrectomy.

Mucoid pseudocyst of the obturator nerve.

A 71-year-old man visited the outpatients' clinic of National Saitama Hospital, Japan, complaining of pain in the right leg. Magnetic resonance imaging (MRI) revealed a cystic mass adjacent to the right side of the urinary bladder. He underwent the removal of the cystic mass and the pathological diagnosis was a mucoid pseudocyst of the obturator nerve. After tumor resection, the pain was diminished and he has been free of disease for 3 years.

[Bladder carcinoma metastases presenting as intraperitoneal dissemination without local recurrence: a case report].

A 76-year-old woman presented with gross hematuria and was referred to our OPD. Cystoscopy showed broad-based papillary tumors on the left bladder wall. TUR-BT was performed and pathological diagnosis was grade 3 transitional cell carcinoma of pT1a. Although no intravesical tumor recurrence had been observed, a solid palpable mass was noted in the lower abdomen nine months after TUR-BT, and computed tomography suggested a large ovarian tumor. Subsequently performed was the operation at Gynecology, which revealed a large tumor involving the whole major omentum. Frozen sections of the tumor were diagnosed as transitional cell carcinoma metastases of the bladder cancer, and the final pathological report was the same. Although receiving 4 courses of M-VAC systemic chemotherapy after the operation, she died 14 months later. Autopsy disclosed intraperitoneal cancer dissemination and metastases without any intravesical nor left perivesical tumor recurrence, and it was suggested that the bladder tumor metastases occurred not by direct invasion but by either lymphatic or vascular mechanism in this case.
