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 the procedure, more interest and well-designed studies are required for the establishment of the procedure.

Purpose: The aim of this study was to assess the efficacy and safety of tamsulosin, 0.2mg/day on sexual function in Korean BPH patients. Patients and Methods: 116 patients (mean age: 60 yrs) with BPH were enrolled in this study and 0.2mg of tamsulosin was administrated every night for 3 months. Primary efficacy was evaluated with changes of IIEF and GEQ. Secondary efficacy parameters were changes of IPSS and QoL, uroflowmetry, changes of total IIEF and IIEF domain score according to the severity of IPSS, and retrograde ejaculation. Results: Before treatment, patients of moderate IPSS (8-19) and severe IPSS (20-35) were 56% and 44% and QoL<3 and QoL>3 were 33.6% and 66.4%. In primary efficacy evaluation, total IIEF score was significantly increased from 37.0±18.2 to 40.5±18.9 (p<0.01). All domains of IIEF except orgasmic function were significantly improved. GEQ showed improvement of erection in 34.4% and intercourse ability in 30.1%. In secondary efficacy evaluation, IPSS was significantly decreased from 18.4±6.9 to 12.9±6.7 (p<0.01) and QoL was significantly improved from 3.8±1.1 to 2.7±1.4 (p<0.01). Qmax significantly increased from 14.2±8.3 to 16.5±11.3 ml/sec (p<0.01). Total IIEF score and EF domain score were significantly improved from 36.8±18.5 to 41.8±19.1 (p<0.01) and from 13.0±7.1 to 14.7±7.9 (p<0.01) in patients of moderate IPSS but no improvement in severe patients. Retrograde ejaculation occurred in 2 patients (2%). No serious adverse reactions were observed. Conclusions: Tamsulosin, 0.2mg/day was effective and safe dose for the improvement of LUTS and sexual function for Korean BPH/LUTS patients.
