Correlation between prostatic parameters of transrectal ultrasonography and age in patients with benign prostatic hyperplasia / 中华男科学杂志

Objective@#To investigate the correlation of prostatic parameters of transrectal ultrasonography with age in patients with benign prostatic hyperplasia (BPH) and the patterns of prostatic enlargement in different age groups of the patients.@*METHODS@#We retrospectively studied the reports of transrectal ultrasonography for 1 739 outpatients with BPH from January 2010 to December 2015, who were divided into four age groups, 50－59, 60－69, 70－79, and =≥80 years. We analyzed the patterns of prostatic enlargement in different age groups.@*RESULTS@#The transrectal ultrasonographic prostatic parameters, most significantly the transitional zone index (TZI), of the BPH patients were positively correlated with age. And the prostatic parameters were gradually increased with aging, with statistically significant differences among different age groups (P <0.05). The prostate was enlarged most quickly between 50 and 69 years of age.@*CONCLUSIONS@#There is a positive correlation between age and prostatic parameters of transrectal ultrasonography, particularly the transitional zone index, in patients with BPH, which indicates that TZI can serve as one of the best criteria in evaluating BPH. The volume of the prostate, especially that of the transitional zone, is increased with aging, reaching the peak between 50 and 69 years, which is of great significance for further study of the development and progression of BPH.

Reconstructive surgery for male urethral stricture affects erectile function and sexual life quality / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the influence of reconstructive surgery for male urethral stricture on erectile function and sexual life quality.</p><p><b>METHODS</b>We analyzed retrospectively the clinical data of 326 male patients who underwent urethroplasty for urethral stricture in our department and evaluated their erectile function and sexual life quality.</p><p><b>RESULTS</b>A total of 172 groups of valid data were collected, with the mean follow-up of 28.5 months. The mean scores on IIEF-5 (P=0.002) and sexual life quality (P=0.026) were statistically significantly reduced after surgery. Erectile dysfunction was found in 88 (51.2%) of the patients after urethroplasty, as compared with 56 (32.6%) preoperatively.</p><p><b>CONCLUSION</b>The location of urethral stricture, surgical method and urethral stricture recurrence may affect the erectile function and sexual life quality of the patient, but both can be gradually improved with the time after urethroplasty.</p>
