RESUMEN
A 69-year-old male with the complaint of a cough was referred to our hospital from a clinic where he was found to have simultaneous metastases of the left kidney tumor. We performed left cytoreductive nephrectomy, and administered sunitinib after the surgery. The first line treatment was not effective. Then we changed the therapeutic agent to pazopanib as the second line treatment. Lung and lymph node metastases gradually shrunk, but he developed right vision disorders and was diagnosed with bilateral metastatic retinal tumors. First, irradiation to the right eye was performed while discontinuing pazopanib. Sudden treatment withdrawal caused his general condition to worsen temporally, but irradiation could be continued by resuming administration of pazopanib. As a consequence, the progression of the visual field disorder was suppressed by the additional ophthalmologic treatment. Renal cell carcinoma choroidal metastases are rare, but we need to consider them when the patient has vision disorders.

We aimed to clarify prophylactic antimicrobial effects of single-dose piperacillin (PIPC) for perioperative infections in the transurethral resection of bladder tumor (TURBT) in comparison with those of single-dose tazobactam/piperacillin (TAZ/PIPC) through a retrospective analysis. We analyzed data from 192 TURBT patients treated with single-dose (4 g) intravenous PIPC (P group) between April 2015 and April 2017. For comparison, we analyzed data from 50 TURBT patients treated with single-dose (4.5 g) intravenous TAZ/PIPC (T/P group) between June 2013 and April 2014. We compared the perioperative incidences of fever (≥38 °C) and bacteriuria in the two groups. The number of febrile patients was four (2.1%) in the P group and one (2.0%) in the T/P group, without significant difference (p = 0.970). Among these febrile patients, urine and blood samples of two patients in the P group tested positive for bacterial cultures of Citrobacter koseri and Enterococcus faecalis, respectively. None of the patients in the T/P group tested positive for urine culture, postoperatively. However, 22 patients (18.2%) in the P group tested positive for urine culture, and Staphylococcus epidermidis (six patients), E. faecalis (three patients), Escherichia coli (three patients), Streptococcus agalactiae (two patients), Staphylococcus aureus (two patients), and C. koseri (one patient) were isolated. There was no significant difference in the incidence of bacteriuria in these two groups (p = 0.055). Based on these results, single-dose PIPC administration for the prevention of perioperative infections in TURBT was as effective as TAZ/PIPC.

Adrenocortical carcinoma is a rare cancer with poor prognosis. We report a case of metastatic adrenocortical carcinoma in a 61-year-old man successfully treated with multimodal therapy. A left adrenal tumor was detected incidentally in the patient and an adrenalectomy was performed. The pathological diagnosis was adrenocortical carcinoma, stage II. After 1 year, multiple local recurrences were detected in the retroperitoneum space. The patient underwent a metastasectomy and received three courses of adjuvant chemotherapy consisting of etoposide, doxorubicin, and cisplatin plus mitotane. No obvious recurrence has been observed in the 60 months since the treatment.

Primary aldosteronism characterized by the overproduction of aldosterone by the adrenal glands, is sometimes accompanied by autonomous cortisol secretion. In this study, we retrospectively analyzed 8 cases of primary aldosteronism (PA) with subclinical Cushing's syndrome (SCS). A total of 71 patients with PA underwent surgery at Jikei University Hospital from 2004 to 2013, and 8 of them were diagnosed with coexistent SCS. Four patients were male and four were female. The mean patient age was 56.9 years. One of the patients also had pheochromocytoma in the adrenal gland on the ipsilateral side. All patients had hypertension, 6 had hypokalemia, 5 had diabetes mellitus, and 3 had hyperlipidemia. All patients had autonomous cortisol secretion as shown in 1 mg- or 8 mg-dexamethasone suppression tests even though baseline cortisol levels were normal. Adrenal venous blood sampling with adrenocorticotropic hormone (ACTH) stimulation was performed on 5 patients, but the localization of PA could not be detected in 1 patient. Adrenocortical scintigraphy revealed suppression of the contra-lateral adrenal uptake in all 7 patients. Six patients including one patient who showed complete suppression of the contra-lateral adrenal uptake in adrenocortical scintigraphy, and 2 patients, whose ACTH levels were less than the detection limit, received postoperative steroid hormone replacement. In the literature, SCS co-existed in approximately 8. 6% of the patients with PA. In our study, SCS co-existed in approximately 11.3%. The degree of the autonomous secretion of cortisol varied with the patient, and some cases are accompanied by Cushing's syndrome. Therefore, it is important to analyze the autonomous cortisol secretion even in patients with PA.

We report a case of percutaneous bacillus Calmette-Guérin (BCG) perfusion therapy for carcinoma in situ (CIS) of upper urinary tract after radical cystectomy with ileal neobladder. A 42-year-old man underwent radical cystectomy and ileal neobladder diversion due to the recurrence of CIS in prostatic urethra after transurethral resection of bladder tumor 3 times and 2 courses of intravesical BCG therapy. Final pathological findings showed the presence of CIS in the right distal ureteral margin. After the radical cystectomy, our diagnosis was CIS in the right residual ureter, because of positive urine cytology and negative radiographic findings in the upper urinary tract. We performed the percutaneous BCG perfusion therapy for CIS of the right upper urinary tract after the construction of the percutaneous nephrostomy by intentionally inducing hydronephrosis. No recurrence was found after 3 years of BCG perfusion therapy.

The cure rate of hypertension after surgery for primary aldosteronism (PA) was assessed in a single institution. In the present study, we studied the risk factors on the cure rate of hypertension after surgery in patients with PA. Thirty-five patients who underwent surgery for PA between January 2004 and December 2009, with a follow-up time of 1 year or longer were studied. The mean age at surgery was 50.7 years old. The male to female ratio was 24 : 11. Factors confounding the cure rate of hypertension after surgery were analyzed using the univariate and the multivariate analysis. Nineteen (54%) of the 35 patients were completely cured after surgery. In most cases, a complete cure was seen within 1 month after surgery. At 1 year after surgery, the dose of medication for hypertension could be decreased in 11 (13%) of the 16 non cured patients. Although hypertension in patients with PA may be curable by surgery, the cure rate of hypertension after surgery has been reported to be from 16 to 67%. In the present study, age, gender, preoperative serum creatinine, the period of hypertension, the number of medications for hypertension, and family history for hypertension were significant in the univariate analysis for the cure rate of hypertension (persistent hypertension) after surgery. Multivariate analysis showed that the age of 55 years old or older was a significant predictor for non-curable hypertension after surgery. Our result suggests that earlier surgery may contribute to a better outcome on the cure rate of postoperative hypertension in patients with PA.

Herein, we report two cases of female urethral cancer. Case 1 presented with acute urinary retention and case 2 presented with a painful perineal mass. Magnetic resonance imaging (MRI) revealed a urethral tumor in both cases. Histopathological examination of transperineal biopsy specimens from both patients suggested clear cell adenocarcinoma in case 1 and squamous cell carcinoma in case 2. Both cases underwent total urethrectomy with partial resection of the vaginal wall and cystostomy urinary diversion. With reference to case 1, obturator lymph node metastases were observed during surgery, and treatment comprised combined radiotherapy to 60 Gy and chemotherapy with 5-fluorouracil and cisplatin following surgery. However, metastases appeared in the lung 6 months after initial treatment and she died 20 months after surgery. For case 2, tumor marker failure was observed 5 months after surgery. The same combined treatment was performed and a complete response was obtained. At 19 months after surgery, the patient showed no evidence of recurrence.
