Simultaneous transurethral bipolar enucleation of the prostate, supine ultrasound-guided percutaneous nephrolithotomy and open cystolithotomy: A feasible and safe approach.

Management of the coexisting hard renal pelvic stone, large urinary bladder stone and benign prostatic hyperplasia is not common which can be difficult. Here we reported a case of a 70-year-old Asian male who presented with 1.5cm renal pelvic stone, 5cm large bladder stone and 96 cc benign enlarged prostate, which were managed by simultaneous transurethral bipolar enucleation of the prostate (BipoLEP), supine ultrasound-guided percutaneous nephrolithotomy (PCNL) and open cystolithotomy. Simultaneous transurethral BipoLEP, supine ultrasound-guided PCNL and open cystolithotomy are feasible and safe, with the advantage of minimizing the patient's operation and anesthesia time.

Transurethral resection of prostate for acute urinary retention is linked to shorter survival in younger men.

It is largely unknown whether lower urinary tract symptoms (LUTS) or acute retention of urine (AROU) is linked to shorter life expectancy in men. We conducted a multicenter, retrospective database analysis of patients undergoing transurethral resection of prostate (TURP) to study their relationships. Multivariate Cox regression analysis and Kaplan-Meier analysis with stratification to age and indication of TURP were performed. We further performed an age- and sex-matched survival analysis with the general population using data from the Census and Statistics Department of the Hong Kong Special Administrative Region (Hong Kong, China). From January 2002 to December 2012, 3496 patients undergoing TURP were included in our study, with 1764 patients in the LUTS group and 1732 patients in the AROU group. Old age, ischemic heart disease, cerebrovascular accident, and AROU were risk factors of mortality. Patients aged <70 years (adjusted hazard ratio [HR]: 1.52, 95% confidence interval [CI]: 1.11-2.09, P = 0.010) and 70-80 years (adjusted HR: 1.39, 95% CI: 1.15-1.70, P = 0.001) in the AROU group had worse survival than those in the LUTS group, but such difference was not demonstrated in patients aged >80 years. Compared to the general population, younger patients in the LUTS group appeared to have better survival (<70 years, P = 0.091; 70-80 years, P = 0.011), but younger patients in the AROU group had worse survival (<70 years, P = 0.021; 70-80 years, P = 0.003). For patients aged >80 years, survival was similar with the general population in both the LUTS and AROU groups. In conclusion, AROU at young age was associated with mortality, while early detection and management of LUTS may improve survival.

Comparison of Detrusor Muscle Sampling Rate in Monopolar and Bipolar Transurethral Resection of Bladder Tumor: A Randomized Trial.

PURPOSE: Our aim was to investigate the detrusor muscle sampling rate after monopolar versus bipolar transurethral resection of bladder tumor (TURBT). METHODS: This was a single-center, prospective, randomized, phase III trial on monopolar versus bipolar TURBT. Baseline patient characteristics, disease characteristics and perioperative outcomes were compared, with the primary outcome being the detrusor muscle sampling rate in the TURBT specimen. Multivariate logistic regression analyses on detrusor muscle sampling were performed. RESULTS: From May 2012 to December 2015, a total of 160 patients with similar baseline characteristics were randomized to receive monopolar or bipolar TURBT. Fewer patients in the bipolar TURBT group required postoperative irrigation than patients in the monopolar TURBT group (18.7 vs. 43%; p = 0.001). In the whole cohort, no significant difference in the detrusor muscle sampling rates was observed between the bipolar and monopolar TURBT groups (77.3 vs. 63.3%; p = 0.057). In patients with urothelial carcinoma, bipolar TURBT achieved a higher detrusor muscle sampling rate than monopolar TURBT (84.6 vs. 67.7%; p = 0.025). On multivariate analyses, bipolar TURBT (odds ratio [OR] 2.23, 95% confidence interval [CI] 1.03-4.81; p = 0.042) and larger tumor size (OR 1.04, 95% CI 1.01-1.08; p = 0.022) were significantly associated with detrusor muscle sampling in the whole cohort. In addition, bipolar TURBT (OR 2.88, 95% CI 1.10-7.53; p = 0.031), larger tumor size (OR 1.05, 95% CI 1.01-1.10; p = 0.035), and female sex (OR 3.25, 95% CI 1.10-9.59; p = 0.033) were significantly associated with detrusor muscle sampling in patients with urothelial carcinoma. CONCLUSIONS: There was a trend towards a superior detrusor muscle sampling rate after bipolar TURBT. Further studies are needed to determine its implications on disease recurrence and progression.

Prostatic artery embolization in treating benign prostatic hyperplasia: a systematic review.

INTRODUCTION: We systemically reviewed the current evidence on prostatic artery embolization (PAE) in treating men with benign prostatic hyperplasia. METHODS: A systemic literature search was conducted in PubMed, EMBASE and Web of Science on 1 May 2016 without time constraints. Outcomes of interest included the changes in the International Prostate Symptom Score (IPSS), quality-of-life (QOL) score, peak urinary flow (Qmax), post-void residual urine (PVR), International Index of Erectile Function (IIEF) score, prostate volume (PV) and prostate-specific antigen (PSA) level. RESULTS: A total of 987 records were identified through database searching. After removing duplicates, screening and reviewing full-length texts, a total of five records remained, with two randomized controlled trials and three non-randomized cohort studies. Transurethral resection of prostate resulted in better IPSS than PAE. Open prostatectomy had better IPSS, QOL score, Qmax and PVR, but worse IIEF score than PAE at 1 year. Unilateral PAE had higher rate of poor clinical outcome than bilateral PAE, but the difference became statistically insignificant after adjusting for age; IPSS, QOL score, Qmax, PVR, IIEF score, PV and PSA did not differ between the two groups. PAE with 100 µm PVA particles resulted in greater reduction in PSA level, but worse IIEF score than PAE with 200 µm PVA particles; IPSS, QOL score, Qmax, PVR, PV and poor clinical outcome did not differ between the two groups. CONCLUSION: Evidence on different aspects of PAE was limited. Further studies are warranted to investigate the role of PAE as compared to other forms of medical and surgical treatment.

Effect of vardenafil on blood pressure profile of patients with erectile dysfunction concomitantly treated with doxazosin gastrointestinal therapeutic system for benign prostatic hyperplasia.

PURPOSE: We investigated the effect of the combination of the doxazosin gastrointestinal therapeutic system and 10 mg vardenafil on the hemodynamic status of patients with benign prostatic hyperplasia and erectile dysfunction. MATERIALS AND METHODS: This was a double-blinded, randomized, placebo controlled crossover trial. Patients with benign prostatic hyperplasia and erectile dysfunction treated with the doxazosin gastrointestinal therapeutic system on a regular basis, with no other antihypertensive events, were recruited. Subjects took 10 mg vardenafil or placebo in a randomized crossover fashion with a washout period of at least 7 days between each treatment. The supine and standing blood pressure of the subjects was recorded from 1 hour before to 6 hours after the administration of vardenafil or placebo. The primary outcome of the study was the maximal change in standing systolic blood pressure of the subjects from 1 half hour before to 6 hours after the administration of drugs. RESULTS: A total of 37 patients, 25 (67.6%) and 12 (32.4%) on the doxazosin gastrointestinal therapeutic system at 4 mg and 8 mg, respectively, completed the trial. The combination drug therapy resulted in a maximal decrease in standing systolic blood pressure of 6.18 mm Hg (95% CI -12.02, -0.33; p = 0.039). Only 1 patient had an asymptomatic standing systolic blood pressure of less than 85 mm Hg. Otherwise no symptomatic hypotension or clinically significant adverse cardiovascular event was observed during the study. CONCLUSIONS: In patients on the doxazosin gastrointestinal therapeutic system for benign prostatic hyperplasia a single 10 mg dose of vardenafil had no symptomatic hemodynamic effects.
