RESUMEN
Psoas muscle mass index (PMI) is related to sarcopenia. We examined whether PMI is associated with early complications after radical cystectomy. Seventy one male and 29 female patients who were 65 years old or older and who had undergone radical cystectomy at our hospital from April 2005 to March 2018 were retrospectively analyzed. Psoas muscle section area was measured manually on preoperative computed tomography (CT) scan and normalized by patient's height. Early postoperative complications of grade 3 or more occurred in 12 male (16.9%) and 5 female (17.2%) patients. PMI was lower in male patients who had early postoperative complications of grade 3 or more than in those without complications (5.61 vs 6.54 cm2 /m2, p=0. 08), although the difference was not statistically significant. There was suggested to be a relationship between early postoperative complications after radical cystectomy and preoperative PMI in elderly male patients.

OBJECTIVES: To examine the long-term outcomes of transurethral resection of the prostate. METHODS: We retrospectively collected the data of patients who had undergone transurethral resection of the prostate before December 2010. Patients had been evaluated by urodynamics and the International Prostate Symptom Score preoperatively, and they were re-evaluated by using the International Prostate Symptom Score at the minimum 7 years after transurethral resection of the prostate. Patients who received any treatments to improve voiding symptoms were defined as having a relapse of voiding dysfunction. The Schäfer nomogram was used to assess the degree of obstruction and detrusor contractility. We assessed the change in International Prostate Symptom Score over time depending on obstruction (Schäfer grade 3-6) versus no obstruction (Schäfer grade 0-2), and normal detrusor contractility (strong and normal) versus detrusor underactivity (weak and very weak). Relapse rates of voiding dysfunction were determined using the Kaplan-Meier method. RESULTS: A total of 39 patients were included. The mean age at transurethral resection of the prostate was 69.8 years, and the mean observation period after transurethral resection of the prostate was 114 months. During the observation period, eight patients (21%) were categorized as relapse of voiding dysfunction and the mean time to relapse was 4.2 years. Patients categorized as no obstruction or detrusor underactivity had a higher recurrence rate of voiding dysfunction with a statistical significance between those with versus without obstruction. Except for patients with relapse of voiding dysfunction, improvement of the International Prostate Symptom Score was maintained over a period of 10 years after transurethral resection of the prostate. CONCLUSIONS: Favorable long-term symptomatic outcome after transurethral resection of the prostate is likely in patients with urodynamic obstruction. Patients without urodynamic obstruction are likely to have a relapse of voiding symptoms and require additional treatments in the long term.

The patient was a 66-year-old man who had undergone ileocystoplasty and right nephrectomy at the age of 21 for the treatment of urinarytract tuberculosis. He had been receiving hemodialysis from the age of 58. Regular computed tomography (CT) examination at the age of 63 revealed a bladder mass, but the transurethral biopsyof the bladder mass did not reveal malignant findings. At the age of 66, his urine cytology indicated a suspicion of malignancy, and bladder tumor was detected by cystoscopy. The patient was referred to our hospital and we performed transurethral resection of the bladder tumor. Pathological diagnosis was papillaryadenocarcinoma. Because left lower ureteral cancer was also suspected byCT scan, we performed left nephroureterectomy and radical cystectomy. Pathological examination revealed adenocarcinoma of the reconstructed bladder. The patient remains free of disease for 1 year and 11 months after the operation. Forty-five cases of bladder cancer after enterocystoplasty have been reported in Japan. There are no guidelines for follow-up protocols after enterocystoplasty. A long-term follow-up is mandatory because of the possibilityof development of bladder malignancylong after the enterocystoplasty.

OBJECTIVES: To examine the long-term persistence rate with mirabegron in a real-world clinical setting. METHODS: We retrospectively collected the data of patients who were prescribed mirabegron. We investigated the persistence rate and the reason for the discontinuation. The analysis included patient's age, diagnosis, Overactive Bladder Symptom Score, prostatic volume, the prescription by specialists for lower urinary tract dysfunction, drug-naïve patients, replacement of antimuscarinics or add-on therapy to antimuscarinics. RESULTS: A total of 556 patients were included. Among them, 401 patients (72%) had overactive bladder and the other 155 (28%) were categorized as having other storage symptoms. During the observation period, 170 patients (42%) with overactive bladder discontinued mirabegron. The reasons for discontinuation in patients with overactive bladder included unmet expectation of treatment (45 patients, 26%), any adverse events (38 patients, 22%) or symptom improvement (37 patients, 22%). The persistence or discontinuation was not related with age, Overactive Bladder Symptom Score, prostatic volume or the prescription by specialists, while older male patients tended to continue mirabegron. The 3-year persistence rates in female and male overactive bladder patients were 46% and 51%, respectively, and these were better than those in patients with storage symptoms without urgency. In female overactive bladder patients, the persistence rate with mirabegron used as add-on therapy to antimuscarinics was higher than that in the drug-naïve patients on the Kaplan-Meier curve. CONCLUSIONS: The present study shows a relatively good long-term persistence rate with mirabegron in overactive bladder patients, notwithstanding the retrospective study in an academic hospital. The combined treatment with antimuscarinics could result in a good persistence rate with mirabegron.

OBJECTIVES: To investigate if uroflowmetry (UFM) curve patterns could differentiate between detrusor underactivity (DU) and bladder outlet obstruction (BOO). METHODS: A hundred consecutive data sets of male patients who were evaluated using UFM and invasive urodynamics (pressure flow study) were retrospectively collected. DU and BOO were diagnosed according to the bladder contractility index and BOO index. The UFM curve with two or more notches was defined as sawtooth pattern, and the interrupted pattern was defined if several curves with interruptions reducing to zero were noted. We also compared other UFM parameters including maximum and average flow rates (Qmax and Qave), voiding time, time to Qmax, the slope to first peak flow, the number of notches on the curve (sawtooth pattern), the number of curves (interrupted pattern), and the maximum drop on the sawtooth pattern. RESULTS: Twenty-five and forty-nine patients were categorized in the BOO group and the DU group, respectively. The incidence of sawtooth pattern was significantly higher in the DU group (57%) than in the BOO group (32%), while the incidence of interrupted pattern was not different between the two groups (36% in the BOO group and 49% in the DU group). There were significant differences in age (area under the curve = 0.75), prostatic volume (0.67), the slope to first peak flow (0.58), the number of notches on the curve (0.61), and the maximum drop (0.76) between the two groups. CONCLUSIONS: The sawtooth UFM pattern is more common in patients with DU than in those with BOO. New parameters on UFM curve patterns could be helpful to evaluate DU and BOO without invasive urodynamics.
