RESUMEN
INTRODUCTION AND HYPOTHESIS: Constipation is reported to be associated with urinary incontinence. However, the reported results have been inconsistent and contradictory. To evaluate the association between constipation and urinary incontinence in women, we performed a meta-analysis. METHODS: A comprehensive search based on PubMed, EMBASE, and the Cochrane Library was performed up to July 2018 for eligible studies in relation to the influence of constipation on urinary incontinence in women. A random-effect model was used to calculate the pooled odds risk (OR) and corresponding 95% confidence interval (CI). RESULTS: A total of 16 observational studies with 35,629 participants and 6054 urinary incontinence patients were identified in the meta-analysis. Constipation was significantly associated with the risk of urinary incontinence in women (OR 2.46, 95% CI 1.79-3.38). CONCLUSIONS: This meta-analysis suggests that constipation is significantly associated with urinary incontinence risk in women. However, further well-designed, large-scale prospective studies are needed to clarify the causality.

OBJECTIVE: To investigate the correlation of vasectomy with the risk of prostate cancer in Chinese men. METHODS: We systematically searched the databases CNKI, VIP, Wanfang, PubMed, Embase, and Cochrane Library for the literature relating the relationship between vasectomy and the risk of prostate cancer in Chinese males up to December 2014. According to the inclusion and exclusion criteria, two investigators independently selected the eligible publications, evaluated their quality, and extracted relevant information, followed by a meta-analysis with the software STATA 12.0. RESULTS: Nine studies were included in the analysis involving 1 202 cases of prostate cancer and 4,496 controls. Random-effect model analysis revealed no statistically significant correlation between vasectomy and the risk of prostate cancer (OR = 1.05; 95% CI 0.62-1.79), with an obvious heterogeneity (P < 0.001, I2 = 85.7%). No significant publication bias was found among the included studies (Egger, P = 0.824; Begg, P = 0.348). CONCLUSION: The results of our meta-analysis do not support the association of vasectomy with the increased risk of prostate cancer in Chinese population.

BACKGROUND: The association between gonorrhea and prostate cancer risk has been investigated widely, but the results remain inconsistent and contradictory. We conducted an updated meta-analysis to obtain a more precise estimate of this association. MATERIAL AND METHODS: PubMed, EMBASE, and the Cochrane Library were searched for papers up to June 2014 to identify eligible studies. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the influence of gonorrhea on prostate cancer risk. RESULTS: Twenty-one observational studies (19 case-control and 2 cohort) were eligible, comprising 9965 prostate cancer patients and 118 765 participants. Pooled results indicated that gonorrhea was significantly associated with increased incidence of prostate cancer (OR 1.31, 95% CI 1.14-1.52). The association between gonorrhea and prostate cancer was stronger in African American males (OR 1.32, 95% CI 1.06-1.65) than in Whites (OR 1.05, 95% CI 0.90-1.21). CONCLUSIONS: Our findings suggest that gonorrhea is associated with an increased risk of prostate cancer, especially among African American males. These results warrant further well-designed, large-scale cohort studies to draw definitive conclusions.

OBJECTIVE: To investigate the efficacy and safety of corpus cavernosum-corpus spongiosum shunt (CC-CSS) plus intracavernous tunneling(CC-CSS+ICT) for the treatment of prolonged ischemic priapism (PIP) were investigated. METHODS: Of 21 patients with PIP, 11 (Group A) underwent CC-CSS and 10 (Group B) CC-CSS+ICT surgery. The penile hardness score (PHS) and pain visual analogue score (PVAS) were used to assess the efficacy of the surgery. RESULTS: The erectile functions of the two groups were normal (IIEF5 23.6+/-1.1) before the onset of PIP, and the duration of PIP was (3.4+/-1.3) d. PHS 3.9+/-0.4, and PVAS 8.4+/-0.7. There was no statistical difference between the two groups (P>0.05). On 1, 3 and 5 days after the operation, the PHS and PVAS of Group B decreased significantly than those of Group A (P<0.05). CONCLUSION: CC-CSS+ICT could quickly restore penile detumescence and relieve pain as compared with CC-CSS, which might be a safe and effective method for the treatment of PIP.

OBJECTIVES: To investigate clinical features of Chinese patients with severe primary erectile dysfunction (S-PED) and to identify the ideal treatment options for this population. METHODS: Patients with PED were screened for enrollment in our study. Sexual history, marital status, and erectile function were evaluated by inquiry including International Index of Erectile Function-5. Individuals with severe PED (defined as refractory to management with phosphodiesterase type 5 inhibitor [PDE5i]) underwent serum hormone analysis, penile color duplex Doppler ultrasound, neuroelectromyogram, and cavernosography as appropriate. Long-term treatment results were determined. RESULTS: Among 220 PED patients, 72 (32.7%) suffered from severe PED (PDE5i nonresponse). Mean age was 31.5 +/- 4.5 years and mean duration of attempts at sexual activity was 2.4 +/- 3.2 years, Sixty-eight men (94.5%) had organic etiologies for erectile dysfunction, including arteriogenic (n = 13), venogenic (n = 35), endocrinologic (n = 6), neurologic (n = 9), and cavernosal fibrosis (n = 5). Sixteen men (22.2%) had been divorced. Mean erectile function and quality-of-life were significantly improved (P <.001) in the 25 men (34.7%) who were treated by penile prosthesis implantation, at a mean follow-up of 5.6 years. Satisfaction with penile prosthesis for patients and partner was 93.4% and 92.3%, respectively. CONCLUSIONS: Severe PED has a major impact on young couple's life quality. Venous leak is the most common cause of severe PED. Penile prosthesis implantation is safe and effective for severe PED.
