RESUMO
This study investigated the significance of urological surgical intervention for viral hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). A total of 1, 024 patients underwent allo-HSCT at our medical center between January 2006 and July 2014. In the 6 patients (0.58%) who required urological surgical treatment for viral HC, we retrospectively analyzed patient characteristics and outcomes. Two patients underwent nephrostomy for bilateral hydronephrosis due to bladder tamponade. One of these patients showed no improvement in renal function, graft versus host disease worsened and he died on postoperative day (POD) 5. The other patient displayed improved renal function but hematuria did not improve, and total cystectomy was required. To control bleeding, we performed transurethral electrocoagulation (TUC) on 3 patients, and total cystectomy was performed on 2 patients. All 3 patients who underwent TUC had BK virus HC. Two of these patients experienced marked improvement in hematuria from immediately after surgery. Hemostasis was only temporary in the other patient, who eventually died due to septicemia on POD 24. The 2 patients who underwent total cystectomy had adenovirus HC. Both experienced secondary hemorrhage postoperatively and required further surgery. Eventually, one died due to postoperative bleeding on POD 1, and one died due to postoperative pneumonia on POD 57. Urological surgical treatment for HC was effective in some cases, but the ultimate outcome greatly depends on the general condition of the patient and treatment of the underlying hematological disorder. TUC may be considered for HC (particularly BK virus HC), but total cystectomy (especially inaden ovirus HC) should be avoided.

We analyzed the pathological findings, surgical margin, the first site of local or distant recurrence, treatment for postoperative recurrence and the characteristics of 25 patients who were surgically treated for retroperitoneal sarcomas between December 2000 and January 2014. The median tumor diameter was 11 cm. The pathological diagnosis was liposarcoma (n = 14), leiomyosarcoma (n = 7) and others (n = 4). Tumors were resected en-bloc with adjacent organs in 17 of the patients. In median follow up period of 39 months, 11 of the 14 patients with liposarcoma experienced local tumor recurrence and distant metastasis did not precede local recurrence in any of these patients. Leiomyosarcoma recurred in all patients and distant metastases appeared before local recurrence in four of them. The five-year recurrence-free and over all survival rates were 28 and 58%, respectively. The recurrence-free and overall survival rates significantly differed between well-differentiated and other subtypes of liposarcoma (both p < 0.05). The overall survival was significantly better for patients with a tumor diameter of < 11 cm than for those with ≥ 11 cm (p 0.05). Furthermore, overall survival was significantly better for patients who were able to undergo re-operation at the time of recurrence than for those who could not (p < 0.005). Although we resected adjacent organs when the margin was insufficient, the rate of local recurrence was high in liposarcoma. On the other hand, the rate of distant metastasis was high in leiomyosarcoma.

Two patients with late recurrence of renal cell carcinoma were observed long term without treatment. Case 1 is an 83-year-old woman who underwent right nephrectomy at 57 years of age following a renal tumor diagnosis. Histopathological results revealed clear cell renal cell carcinoma, G2, pT1aN0M0. Pancreatic metastasis developed at age 71, and pancreatic tail excision was performed. A metastatic lesion appeared again at the head of the pancreas at age 74. The patient has been followed by observation only for 9 years without any new lesions. Tumor doubling time calculated from abdominal ultrasonography was 13.3 months.Case 2 is a 91-year-old male. At 78 years of age, right nephrectomy and inferior vena cava tumor embolectomy were performed for renal tumor. Histopathological results revealed clear cell renal cell carcinoma, G2, pT3bN0M0. Left adrenal metastasis appeared at age 84, and the patient has been followed for 7 years without new lesions. Tumor doubling time calculated from abdominal computed tomography (CT) images was 14.1 months.In both patients, no symptoms due to tumor recurrence ever appeared, and their activities of daily living (ADL) were maintained fairly well. In the case of solitary late recurrence in elderly renal cancer patients, observation may be a treatment option that avoids adverse effects and complications caused by treatment. In addition, it appears possible to predict the need for subsequent treatment by calculating the doubling time using several sequential CT images obtained after recurrence. If a new recurrent metastatic lesion appears or if the doubling time during a 2-to 3-year follow-up period is relatively short, however, new treatment should be considered without delay.

With the widespread use of imaging modalities, incidentally discovered small renal cell carcinomas have increased. Some patients, however, are too old or weak due to various diseases to undergo surgery and other patients occasionally refuse surgery. To investigate the natural history of small renal cell carcinoma, we retrospectively reviewed patients with small renal tumors suggestive of carcinoma. We retrospectively reviewed 15 patients with contrast-enhancing renal masses less than 4.0 cm in diameter who were observed without treatment. The mean follow-up period was 38 months (range, 8-91). The average patient age was 67 years (range, 44-87). The initial average tumor diameter was 2.2 cm (range, 1.0-3.9). The average growth rate was 0.06 cm per year (range, -0.09-0.28). Only 4 tumors grew obviously during the follow-up period. Three tumors were removed surgically by radical nephrectomy, and all tumors were pathologically diagnosed as renal cell carcinoma. None of the patients developed metastases during the follow-up period or after surgery. Two patients died of other causes. Nonsurgical watchful waiting may be an acceptable treatment option for elderly or severely comorbid patients; however, it is not known whether this conservative management can be applied to young or otherwise healthy patients.

We retrospectively evaluated the effect of the surgical resection of the remaining tumor after modified M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin) (m-M-VAC) treatment for locally advanced or metastatic urothelial carcinoma. In m-M-VAC therapy, methotrexate and vinblastine on 15 and 22 days were omitted from the classical M-VAC to avoid the discontinuation and the dose reduction, and duration of 1 course was shortened to 21 days from 28 days of the classical M-VAC. Seven patients with locally invasive or metastatic carcinoma of the renal pelvis, ureter, and bladder, 6 males and 1 female, with a median age 64.1 years, ranging from 49 to 77 years received m-M-VAC chemotherapy without severe side effects. In all patients, the residual viable carcinoma was completely resected and they achieved complete remission. The median survival time was 20 months (range, 7 to 61). Five of these 7 patients were still alive. Two patients had no recurrence and achieved long-term survival (survival duration; 61 and 39 months). Although further studies and long-term follow up are required, these results suggest that patients who present with locally advanced or metastatic urothelial carcinoma may benefit from surgical resection after m-M-VAC.

PURPOSE: To evaluate the efficacy of combined lumbar spinal and epidural (CLSE) anesthesia in retropubic radical prostatectomy. MATERIALS AND METHODS: Twenty consecutive patients who underwent radical retropubic prostatectomy by a single surgeon (H.K.) under CLSE anesthesia from July of 2003 to February of 2004 were selected as subjects. They were compared with 20 consecutive patients who underwent radical retropubic prostatectomy performed by the same surgeon under combined general and epidural (CGE) anesthesia from April to December of 2002. Both periods were carefully selected to exclude radical prostatectomies with intraoperative complications to evaluate genuine effects of anesthesia. For lumbar spinal anesthesia, 0.5% hyperbaric bupivacaine hydrochloride or 0.5% hyperbaric tetracaine hydrochloride (dissolved in a 10% glucose solution) was used. An epidural tube was inserted for both lumbar spinal anesthesia and general anesthesia mainly for the purpose of controlling a pain after operation. RESULTS: Intraoperative blood loss was significantly less in the CLSE anesthesia group compared with CGE anesthesia group (p = 0.024). Postoperative water drinking was started at 0.4 days (average) for CLSE anesthesia and at 1.1 days (average) for CGE anesthesia (p < 0.0001). Postoperative diet was begun at 0.7 days (average) for CLSE anesthesia and at 1.5 days (average) for CGE anesthesia (p < 0.0001). Compared with the CLSE anesthesia group, the mean of the highest intraoperative mean blood pressure was significantly higher in the CGE anesthesia group (p = 0.002). CONCLUSION: Intraoperative blood loss was less, intraoperative change in blood pressure was less and recovery of postoperative intestinal peristalsis was earlier in patients who underwent prostatectomy under CLSE anesthesia than in patients who underwent prostatectomy under CGE anesthesia. We believe that prostatectomy under CLSE anesthesia is more advantageous than prostatectomy under CGE anesthesia.
