| 抄録 | The effects of stone composition on transurethral lithotripsy (TUL) have not been sufficiently elucidated. The purpose of this study was to identify how calcium phosphate stone composition impacts TUL. Two hundred eighty-nine cases of semi-rigid and/or flexible TUL for upper urinary tract calculi were reviewed retrospectively. Inclusion criteria were a preoperative assessment by noncontrast computed tomography (NCCT) and a stone composition analysis. Small stones and those without calcium composition were excluded. Stone core radiodensity (SCR) was measured by taking the average of the upper 3 of 5 points in the proximity of the center of the stone on NCCT. Fifty-three patients with calcium phosphate composition (CaP) and 118 patients with calcium oxalate and without phosphate composition were eligible for analysis. SCR was significantly higher in the CaP group (p<0.01). The CaP patient group needed a significantly longer operation time (p=0.014) and more laser energy (p=0.085), and tended to have a lower rate of complete lithotripsy (p=0.096) and higher incidence of postoperative pyelonephritis (p=0.181). Stones containing calcium phosphate are harder, demand more laser energy, and require a longer operating time. NCCT evaluation can estimate stone composition preoperatively, and may be a useful tool for predicting operative outcomes. |

| 抄録 | The present case report describes a case of recurrent and advanced urachal carcinoma including neuroendocrine features with iliac bone metastasis after partial cystectomy and adjuvant chemotherapy consisting of irinotecan and cisplatin in a 32-year-old man. He received gemcitabine/cisplatin/ paclitaxel (GCP) combination chemotherapy, consisting of gemcitabin (1,000mg/m2) on day 1, 8, cisplatin (70mg/m2) on day 1, and paclitaxel (80mg/m2) on day 1 and 8. After three cycles of chemotherapy, PET-CT showed complete regression of the disease. So the patient underwent total cystourethrectomy, and histological examination showed an almost complete pathological response. External beam radiation therapy was also given to the ileac bone metastasis regions. However, PET-CT taken 17 months after the external beam radiation showed multiple lung metastases. He received GCP chemotherapy again, which resulted in a complete response again after three cycles of chemotherapy. This is the first report on GCP chemotherapy used not only as a salvage chemotherapy but also as a rechallenge regimen for metastatic urachal cancer including a neuroendocrine component. |

| 抄録 | Differentiating patients by age and causative bacterial morphology might aid in making the appropriate choice of antimicrobial agent when treating acute uncomplicated cystitis. In this retrospective analysis, the non-susceptibility rates of the causative bacteria to cefcapene-pivoxil (CFPN-PI) and levofloxacin (LVFX) were determined after dividing patients with acute uncomplicated cystitis by age group (15-54 and 55-74 years old) and by bacterial morphology: gram-positive cocci (GPC) or gram-negative rod (GNR). The overall non-susceptibility rates for CFPN-PI and LVFX were 19.4% and 15.3%, respectively. When the subjects were divided by age, only the non-susceptibility rate for LVFX in the younger group significantly decreased (to 8.7%). When the groups were divided by both age and bacterial morphology, the younger GNR group had non-susceptibility rates of 6.9% to CFPN-PI and 7.8% to LVFX, whereas the younger GPC group showed 10.2% non-susceptibility to LVFX. The older GNR group showed 9.8% non-susceptibility to CFPN-PI, while the older GPC group showed 7.2% non-susceptibility to LVFX. All the non-susceptibility rates were lower than 10.2% in the sub-divided groups. Differentiating patients by age and the morphology of causative bacteria can aid in making the appropriate choice of antimicrobial agent and may improve treatment outcomes in patients with acute uncomplicated cystitis. |
