  • Complications of Glans Penis augmentation
    International Journal of Impotence Research, 2019
    Co-Authors: Sun Tae Ahn, Je Jong Kim, Tae Kwak, Kwang Sung Park, Du Geon Moon
    Abstract:

    Despite the controversy regarding penile augmentation (PA), Glans Penis augmentation (GPA) is used in penile reconstructive surgery in selected patients with small Glans Penis. Since 2003, injectable hyaluronic acid (HA) gel has been used for GPA. The attractiveness of HA gel fillers and interest in this technique have led to the use of other fillers for GPA, particularly irreversible fillers that improve the longevity of HA gels. Conversely, indirect Glans augmentation via implantation of dermofat grafts or scaffolds between the corpus penisme/topic-spongiosum/">spongiosum and the distal tip of the corpus cavernosum is used to overcome poor longevity of the gel and Glans surface undulation, which are the primary limitations of GPA using HA gel. Unfortunately, these implants form hard painful lumps over time in most patients and are difficult to remove. Blunt dissection is an invasive procedure that may cause vascular compromise and consequent Glans necrosis in a few patients. We present our review regarding the current status of GPA for a more comprehensive understanding of this subject. Additionally, we have discussed a few complicated cases that were referred to us.

  • practice patterns among korean urologists for Glans Penis augmentation using hyaluronic acid filler in the management of premature ejaculation
    Sexual Medicine, 2018
    Co-Authors: Hyeong Guk Jeong, Jong Wook Kim, Je Jong Kim, Sun Tae Ahn, Kyung Keun Seo, Dong Soo Lee, Du Geon Moon
    Abstract:

    Abstract Introduction Glans Penis augmentation (GPA) using hyaluronic acid (HA) gel has been developed for treating premature ejaculation (PE) with penile hypersensitivity. The injected HA filler creates a barrier that reduces the tactile stimuli to the hypersensitive dorsal nerve. Although the HA filler is biodegradable and is believed to not cause permanent loss of sexual function, the current International Society for Sexual Medicine guideline for PE does not recommend this procedure owing to concerns regarding sexual dysfunction. Aim To investigate the practice patterns for GPA using HA filler among Korean penisme/topic-urologist/">urologists, and to identify whether penisme/topic-urologist/">urologist experienced patient reports of sexual dysfunction post-treatment. Methods Between March 2016 and July 2016, a specially designed questionnaire was mailed to 86 selected Korean penisme/topic-urologist/">urologists who had used injectable materials to treat PE. Main Outcome Measures The prevalence and awareness of sexual dysfunction after GPA using HA filler were evaluated. Results Overall, 56 penisme/topic-urologist/">urologists completed the survey (response rate: 69.2%), of which 36 (64.3%) had performed GPA using HA filler. They reported having performed a combined total of 4,344 such GPA procedures. Most penisme/topic-urologist/">urologists (72.7%) performed GPA using HA filler in patients who benefit from topical anesthetics. Patients with a history of failed pharmacotherapy (59.1%) and selective dorsal nerve neurotomy (45.5%) were selected for GPA using HA filler. The respondents (44.4%) encountered overall 206 (4.7%) cases of patients reports of recurrence of PE. Interestingly, only 36 (0.8%) cases of Glans pain or paresthesia and no cases of erectile dysfunction post-treatment were reported. Conclusion Korean penisme/topic-urologist/">urologists performed GPA using HA filler when pharmacotherapy failed or if there was a response to topical treatment. Paresthesia and hypoesthesia after GPA using HA filler are rare, and no cases of erectile dysfunction were encountered by Korean penisme/topic-urologist/">urologists. Jeong HG, Ahn ST, Kim JW, et al.

  • efficacy and safety of newly developed cross linked dextran gel injection for Glans Penis augmentation with a novel technique
    Asian Journal of Andrology, 2018
    Co-Authors: Dae Yul Yang, Seong Ho Lee, Jong Wook Kim, Du Geon Moon, Won Ki Lee
    Abstract:

    There is no safe and effective standard method for Glans Penis augmentation. Furthermore, there has been scant research on Glans Penis augmentation due to a poor understanding of Glans anatomy, technical difficulty, and a lack of suitable substances for augmentation. Cross-linked dextran gel is a newly developed filler for soft-tissue augmentation. We evaluated the efficacy and safety of using a novel technique to inject cross-linked dextran gel for Glans Penis augmentation during a 24-week follow-up study. This prospective, single-arm, multicenter study enrolled twenty healthy adult men who underwent Glans Penis augmentation between June and August 2013. Cross-linked dextran gel was injected into the Glans Penis using a simple and easy technique. The sizes of the Glans Penis and individual satisfaction were assessed. Any adverse event was also reported. A total of 18 individuals were analyzed; two of them were lost to follow-up. The mean procedure time and injected volume were about 30 min and 6.6 ± 0.9 ml, respectively. The mean surface areas of the Glans at baseline and 24 weeks were 20.0 ± 3.5 cm2 and 33.6 ± 5.4 cm2 , respectively, representing a mean increase of 68.7% ± 14.0% (P < 0.001). Sixteen individuals (88.9%) were satisfied with the outcomes, and none were dissatisfied. There were no serious adverse events during the study. Cross-linked dextran gel injection for Glans Penis augmentation was easy and showed a significant augmentative effect on the Glans Penis, good durability, and was well tolerated without serious adverse events. Therefore, cross-linked dextran gel injection may be an effective, new technique for Glans Penis augmentation.

    2016
    Co-Authors: Du Geon Moon, Tae Il Kwak, Je Jong Kim
    Abstract:

    Glans Penis augmentation (GPA) has received little attention from experts despite the existence of a subset of patients who may be dissatisfied with a small Glans or poor tumescence of the Glans during erection. Recently, GPA using an injectable filler or implantation of a graft or filler has been developed. Despite a demanding injection technique and inevitable uneven undulation of the glandular surface, GPA using injectable hyaluronic acid (HA) gel is a novel and useful therapy and an effective and safe procedure for soft tissue enhancement. For long-term presence of implants, timed supplementation can be used similar to that for fascial plasty. In complications such as mucosal necrosis of the Glans Penis, most cases occur from the use of non-HA gel or an unpurified form and misunderstanding of the management protocol for immediate side effects. Currently, GPA using injectable HA gel is not recommended in the International Society for Sexual Medicine guideline due to possible sensory loss. In a 5-year long-term follow-up of GPA by subcutaneous injection of HA gel, the residual volume of implants decreased by 15% of the maximal glandular circumference, but was still effective for alleviating the hypersensitivity of the Glans Penis in premature ejaculation patients. For efficacy in premature ejaculation, selection of appropriate candidates is the most important factor for success. GPA does not harm erectile function and is less invasive and irreversible compared to dorsal neurectomy. To refine th

  • long term effects of Glans Penis augmentation using injectable hyaluronic acid gel for premature ejaculation
    International Journal of Impotence Research, 2008
    Co-Authors: Tae Il Kwak, Je Jong Kim, Myeong Heon Jin, Du Geon Moon
    Abstract:

    The authors created the Glans Penis augmentation by injectable hyaluronic acid gel and reported the 6-month result for premature ejaculation. In a total of 38 patients, long-term effects of 5 years were compared to those of 6 months in terms of residual volume of implants and efficacy on premature ejaculation. Maximal glandular circumference measured by tapeline significantly decreased by 15% (P 0.05). Compared to 6-month follow-up, intravaginal ejaculatory latency time and vibratory threshold decreased at 5 years (P<0.05), but still well increased considering those of preaugmentation. Hence, 76% of patients and 63% of partners were still satisfied. There was no serious adverse reaction. In the 5-year long-term follow-up of Glans Penis augmentation by filler, the implants were well maintained and effective for Glans Penis hypersensitivity in premature ejaculation patients.

  • Giant Fibroepithelial Polyp of the Glans Penis
    Korean Journal of Urology, 2009
    Co-Authors: Yoon Dong Kim, Lee Myung-ho, Jun-mo Kim, Young Ho Kim, Eun Seok Koh
    Abstract:

    Yoon Dong Kim, Myung Ho Lee, Jun Mo Kim, Young Ho Kim, Eun Seok Koh From the Departments of Urology and Pathology, College of Medicine, Soonchunhyang University, Bucheon, Korea Fibroepithelial polyps are a benign neoplasm of mesodermal origin that usually occur in the urinary tract. However, a giant fibroepithelial polyp of the Glans Penis is very rare and is strongly linked with long-term condom catheter use. In this article, we report a case of a 45-year-old man who presented with a giant fibroepithelial polyp originating from the Glans Penis. Physical examination showed a 6x3 cm sized mass lesion overlying the ventral surface of the Glans near the urethral meatus without urethral communication. For the previous 10 years, the patient had been required to use a condom catheter secondary to paraplegia sustained during a T12-L1 spinal cord injury. He was successfully treated by wide local excision of the mass and suprapubic cystostomy placement. There was no evidence of recurrence after 12 months of follow-up. (Korean J Urol 2009;50:619-621)
