Background: The purpose of this study was to report the outcomes of patients who underwent penile implantation with AMS 700 LGX inflatable penile prosthesis (IPP) in a single center by a single surgeon., Methods: A total of 342 patients with erectile dysfunction who underwent AMS 700 LGX IPP implantation between October 2014 and April 2016 were included in this study. All patients were evaluated using the International Index of Erectile Function questionnaire preoperatively and at 3, 6, and 12 months postoperatively. We also investigated the mean stretched flaccid penile length before and after surgery as well as the complications related to and the mechanical reliability of the IPP., Results: The questionnaire scores at 12 months were statistically significantly higher than the baseline scores. The mean stretched flaccid penile length was 11.1 ± 0.8 cm at baseline and was longer at 3 (11.9 ± 0.9 cm, P < 0.001), 6 (12.0 ± 0.9 cm, P < 0.001), and 12 (12.2 ± 0.7 cm, P < 0.001) postoperatively. There were no intraoperative or perioperative complications. However, one patient had infection and 10 patients developed mechanical failure during the follow-up duration., Conclusions: The results of our study suggest that the AMS 700 LGX IPP could be used to prevent penile shortening in patients undergoing IPP implantation. Furthermore, erectile function and patient satisfaction were improved excellently.

There has been a great improvement in height and weight of Korean children owing to economic development over the last 25 years. This study aimed to evaluate the penile length of Korean children today and to compare it with a previous Korean study reported in 1987. The cross-sectional study was conducted with 909 Korean boys aged 0-14 years who had been brought to outpatient clinics of five tertiary hospitals (Busan, Ulsan, and Changwon) between September 2013 and May 2015. The stretched penile length (SPL) was measured and the testicular size was measured using orchidometry (mL). Student's t-test or Mann-Whitney U test was used to compare the result of our study and the study reported in 1987. SPL of Korean children gradually increased from 4.1 ± 0.8 cm at 0-1 year old to 9.6 ± 3.0 cm at 13-14 years old, the most rapidly during the age of 13. While body weight and testicular size significantly increased from 1987 in most of age groups, there were no significant changes in SPL although there was in some age groups. Height decreased in the infants < 1 year old and increased in the children > 6 years old. With the great economic development over the last quarter century in Korea, height, body weight, and testicular size of children significantly increased but there was no significant change in SPL except penile growth pattern., Competing Interests: The authors have no potential conflicts of interest to disclose.
