RESUMEN
PURPOSE: Alpha-adrenergic blockers are commonly used as a medical expulsive therapy (MET) for patients with ureteral calculi. The aim of this meta-analysis was to evaluate the efficacy and safety of alpha-adrenergic blockers compared with a placebo when used as a MET. MATERIALS AND METHODS: We carried out a systematic search of the PubMed, EMBASE, and Web of Science databases, and the Cochrane Library, for relevant articles from inception to November 2020. Our aim was to identify placebo-controlled trails in which patients were randomized to receive either alpha-adrenergic blockers (tamsulosin, alfuzosin, doxazosin, terazosin, naftopidil, or silodosin) or a placebo for the treatment of ureteral calculi. RESULTS: According to strict inclusion criteria, database searches identified 8 placebo-controlled studies that included 2284 patients. Generally, α-blockers had no significant effect on the clearance of stones in the urinary tract (risk ratio [RR] = 1.05; 95% confidence interval [CI] = 1.00-1.11). However, subgroup analysis showed that α-blockers were effective in treating distal urinary tract stones (RR = 1.08; 95% CI = 1.02-1.15). With regards to adverse events, our analysis showed that the combination of MET with α-blockers was likely to cause dizziness (RRâ=â1.37; 95% CIâ=â1.06-1.79) and retrograde ejaculation (RRâ=â3.10; 95% CIâ=â1.81-5.29). CONCLUSION: Although α-blockers cannot improve the overall ureteral stone clearance rate, these drugs are still effective for the treatment of stones in the distal urinary tract. However, the application of α-blockers is likely to cause dizziness and/or retrograde ejaculation.

AIMS AND OBJECTIVES: To assess the clinical effect of the multifunctional suprapubic catheter (MSC) on occurrence of cystospasm, catheter occlusion, the catheter-related urinary tract infection and remission of overactivity bladder, by comparing with the conventional suprapubic catheter (CSC) in patients with permanent suprapubic cystostomy. BACKGROUND: The conventional suprapubic catheter usually presents with high incidence of catheter-associated complications. DESIGN: A prospective randomised clinical trial in a single centre. METHODS: Between January 2014 and January 2015, a total of 91 consecutive patients with permanent suprapubic cystostomy were prospectively randomised into two groups: the MSC group (n = 43) and CSC group (n = 48). RESULTS: Our results showed that the total times of cystospasm in the MSC group were significantly less than that in the CSC group during the follow-up time (p < .001). In addition, the mean spasmodic duration per time in the MSC group was significantly shorter than that in the CSC group (p < .001). Besides, catheter occlusions were observed in 23 (25.27%) patients, including 5 (11.63%) in the MSC group and 18 (37.50%) in the CSC group (p = .005). The lower rate of positive urine culture was also found in the MSC group but with no significant difference (p = .540). Furthermore, the urodynamic measurement data demonstrated that the patients in the MSC group had a greater remission rate of overactivity bladder after catheter change (p < .001). CONCLUSIONS: The present data showed that the multifunctional suprapubic catheter could significantly reduce the incidence of catheter occlusion, ameliorate the symptom of cystospasm and relieve the overactivity bladder, but have no influence on the catheter-related urinary tract infection. RELEVANCE TO CLINICAL PRACTICE: The application of our self-devised multifunctional suprapubic catheter may result in better management of the patients with permanent suprapubic cystostomy.

AIMS AND OBJECTIVES: To assess the effects of three different bowel preparation methods on the incidence of infectious complications in patients who underwent transrectal ultrasonography-guided prostate biopsy. BACKGROUND: The standard bowel preparation protocol for prostate biopsy has not been established. DESIGN: A retrospective study in a single centre. METHODS: From January 2013-December 2015, the clinical records of 1,130 patients who underwent prostate biopsy were, respectively, reviewed. All the patients received metronidazole prophylaxis before biopsy. The patients were divided into three groups according to the bowel preparation methods: patients in Group A (n = 402) received only soapy enema; patients in Group B (n = 413) received polyethylene glycol; while patients in Group C (n = 315) received polyethylene glycol plus povidone-iodine enema. Infectious complications were classified as fever (>37.5°C), urinary tract infection and sepsis. The postoperative adverse events were also observed. RESULTS: The overall postbiopsy infectious complications were observed in 48 (4.25%) patients of all the cases, including 23 (5.72%) cases in Group A, 20 (4.84%) cases in Group B and five patients (1.59%) in Group C. There was significant difference among the groups (p = .018). In detail, these infectious complications included 22 (1.95%) cases of fever and 26 (2.30%) cases of urinary tract infection. No sepsis was observed among the total patients. The incidence of adverse events was 14.43% (58/402) occurred in Group A, 25.91% (107/413) in Group B and 26.67% (84/315) in Group C. The difference was statistically significant. CONCLUSIONS: Our study confirmed that combined preparation regimens of polyethylene glycol with povidone-iodine enema could significantly reduce the postbiopsy infection rate. Conventional soapy enema is associated with less adverse events. RELEVANCE TO CLINICAL PRACTICE: Findings of this study provide useful evidence-based information for healthcare professionals. The application of combined preparation regimens of polyethylene glycol with povidone-iodine enema resulted in better improvement in the prevention of postbiopsy infection.

BACKGROUND: Prostate cancer is known to have ethnic and regional differences. The study aimed to clinically evaluate the detection rate of prostate cancer on transrectal ultrasonography (TRUS)-guided prostate biopsy and analyze its characteristics among the northern Han Chinese population at a single center. METHODS: Between October 2009 and September 2016, a total of 1027 Chinese men, who had undergone TRUS-guided prostate biopsy at Qingdao Municipal Hospital, were retrospectively analyzed. Prostate biopsies were performed in the case of an abnormally elevated serum PSA level, and/or abnormal digital rectal examination (DRE) findings, and/or suspicious prostatic imaging findings. RESULTS: Of the 1022 men enrolled in the analysis, 438 patients (42.8%) were diagnosed with prostate adenocarcinoma histologically. When serum PSA levels were divided into five subgroups (less than 4.0, 4.0 to 10.0, 10.0 to 20.0, 20.0 to 100.0, and ≥ 100.0 ng/ml), the detection rates of prostate cancer were 12.4, 15.9, 34.1, 66.2, and 93.8%, respectively. With serum PSA levels of 4.0 to 10.0 ng/ml, the cancer detection rates for a normal DRE and a suspect DRE finding were 13.5 and 58.2%, respectively. Accordingly, the cancer detection rates for a normal imaging and a suspect imaging finding were 13.5 and 58.2%, respectively. Besides, a large proportion of the patients were in the clinically advanced stage. CONCLUSIONS: The present study data reported a relatively higher prostate cancer detection rate of 42.8% and that the majority of the patients presented with clinically advanced prostate cancers within a local clinical urologic practice. An early detection and screening program for prostate cancer is of great need to reduce the burden from this disease among the northern Han Chinese population.
