Objective: Intraoperative hypotension remains a serious adverse event of photodynamic diagnosis‐assisted transurethral resection of bladder tumor with oral administration of 5‐aminolevulinic acid. We conducted a re‐analysis of perioperative hypotension in photodynamic diagnosis‐assisted transurethral resection of the bladder tumor with oral 5‐aminolevulinic acid to ascertain its safety. Methods: A total of 407 cases who underwent transurethral resection of bladder tumors in our institution were reviewed (274 cases for the PDD group with photodynamic diagnosis and 133 for the white light (WL) group without). A classification of hypotension severity was devised to identify risk factors for clinically troublesome hypotension. The distribution of hypotension severity in each of the PDD and WL groups was compared. Additionally, the patient background and perioperative data by hypotension severity were compared only in the PDD group. Results: More patients with moderate and severe hypotension were noted in the PDD group. The renal function was lower with increasing hypotension severity in the PDD group. More patients on general anesthesia were included in the mild and moderate hypotension group, whereas more patients on spinal anesthesia were included in the severe hypotension group. Furthermore, the frequency of side effects other than hypotension tended to increase with hypotension severity. Conclusions: Renal function impairment and the other adverse effects of 5‐aminolevulinic acid may be risk factors for severe hypotension. Mild or moderate hypotension may be caused by general anesthesia and severe hypotension may be caused by spinal anesthesia. To elucidate specific risk factors, further case–control studies are warranted. [ABSTRACT FROM AUTHOR]

Purpose: To compare the prognosis and quality of life between radical cystectomy and bladder conservative treatment for muscle invasive bladder cancer in the real world. Materials and Methods: Patients treated for muscle invasive bladder cancer without metastases were retrospectively evaluated for overall survival, progression‐free survival, and rehospitalization. Results: Of the 141 patients, 62 underwent bladder conservative treatment and 79 underwent radical cystectomy. Patients who underwent radical cystectomy had significantly better progression‐free survival (HR: 1.83, 95% CI: 1.12–3.00; p < 0.01) and overall survival (HR: 1.82, 95% CI: 0.99–3.34; p = 0.03) than those who underwent conservative treatment. However, there was no significant difference in prognosis between patients who refused to undergo radical cystectomy and those who underwent. In addition, rehospitalization rates for complications and additional treatment were significantly higher in patients who received conservative treatment (69.3% vs. 34.2%; p < 0.01), and the length of hospital stay was also prolonged compared to patients who received radical cystectomy (26 vs. 9 days; p = 0.03). Conclusions: Overall, conservative treatment had a significantly poorer prognosis than radical cystectomy, but there was no significant difference in prognosis when comparing patients who refused radical cystectomy and received conservative treatment with those who received radical cystectomy. However, hospitalization rates and length of stay were significantly worse for patients who chose conservative treatment, which may lead to a decline in quality of life. [ABSTRACT FROM AUTHOR]
