The authors had five cases of penoplasty from more than half of the scrotum to the suprapubic region using a fasciocutaneous radial forearm free flap (RFFF) after extensive excision of sclerosing lipogranuloma. Although the harvested RFFF was a rectangular shape, the authors made the shape of scrotum, penile shaft, and suprapubic region by using well designed geometry and several quilting sutures on junction of scrotum and penis. The contour of scrotum and penis was well maintained, and there were no complications, such as scrotal contracture, penile deformity, and erectile dysfunction during the one year follow up period in all five cases. There were no recurrent lesions and no need for further surgery.

Hypospadias is a congenital malformation of the male genitalia. The reconstructive objectives are to obtain voiding with laminar flow and satisfactory sexual function. Several urethroplasty techniques have been described, but for perineal or revisional cases no single technique has shown robust success. In this study, we describe the expanded use of intestinal flaps for urethral reconstruction and report a peculiar request from a patient to undergo peno-urethral separation after successful hypospadias repair with a free ileum flap. A 51-year-old male patient with perineal hypospadias underwent several urethral reconstructive procedures with poor outcomes. A free ileum flap was attempted as a substitute for the urethra. Following successful reconstruction, separation of the neo-urethra (ileum) from the penile body was performed to address the patient's sexual expectations. A free ileum flap proved to be a reliable urethral substitute in perineal hypospadias reconstruction, with a successful outcome. The peno-urethral separation with the creation of an "accessory penis," however peculiar, optimized the results in terms of both sexual and urinary function. Anatomical restoration of the urethra and patient-reported expectations are the key to successful hypospadias reconstructive procedures. Sexual function outcomes and the patient's perception of success should not be underestimated, even when urinary function has been restored.

A 9 year-old male Maltese with dysuria, pollakiuria, and stranguria was brought to the Veterinary Teaching Hospital, Chonnam National University. A right lateral abdominal radiograph was shown that 3 uroliths existed at the caudal aspect of the os penis and 5 uroliths existed in the passage of os penis. Uroliths were extracted by voiding urohydropropulsion and cystotomy in Maltese dog. The complication of cystotomy was hematuria, which might persist up to 2 days postoperatively but dysuria was not observed. So we applied voiding urohydropropulsion and cystotomy, and got a good prognosis. Gross examination of extracted uroliths were separated one from another but it was identified the same componet of calcium oxalate by stone quantitative analysis.

Eight species of bithyniids, Bithynia leachi, B. tentaculata, B. siamensis, B. misella, B. kiusiuensis, B. striatula, Bithynia sp. from Nepal and Gabbia australis were collected from 1957 to 1988. The samples were relaxed with pentobarbital and fixed with 70% ethyl alcohol. There was no significant difference in internal structure of soft body, except the male reproductive system. The alimentary canal of the bithyniids consisted of mouth, buccal mass, esophagus, stomach, intestine, rectum and anus. The heart consisted of an auricle and a ventricle, located at left side of the stomach in the visceral hump. The ctenidium comprised 40-70 subtriangular lamellae. Eight ganglia were located around upper esophagus. The female reproductive system comprised ovary, oviduct, spermaaheca, and albumin gland. The male reproductive system was composed of testis, seminal vesicle, prostate gland, vas deferens, penial duct, and penis in order. Male was distinguished externally from the female by a bifid penis.

A 24-year-old man presented to King Saud Medical City emergency department with a retained bullet in his penis following a civilian exchange of gunfire. After an initial assessment, the patient was taken to the operating room. Penile exploration was performed, the bullet was extracted successfully, and the corpora cavernosa were repaired properly. A 6-week follow-up showed full healing with preservation of erectile function. Immediate surgical intervention is mandatory as the primary treatment for penile gunshot injury to ensure proper anatomical and functional recovery.

This study analyzed the characteristics and patterns of men's drawers panties to get basic data for their design. For this, drawers panties in 7 different brands (4: domestic brands, 3: imported brands) in terms of a front-center shape were collected, and the shape of men's drawers panties, characteristics of the materials, dimensions & type of patterns by the part and front-center patterns were analyzed. The study results found the followings: First, in terms of the shape of men's drawers panties, the front-center part were designed to rest the penis and scrotum in a natural and comfortable manner without a pee slit. They were seamless on the sides except for one product with side seams. Second, the drawer panties were made of elastic polyurethane materials. Specifically, domestic brand items used warm, elastic and durable nylon, polyester and rayon and polyurethanes while imported brands were mostly made of absorbent and sanitary polyurethanes. Third, regarding a size of drawer panties by part, imported brands were large in waist circumference. In terms of waist breadth at the front center, there was difference depending on an oval type. In addition, the front length at the front center differed by product, revealing difference in three-dimensional effect at the front center. The side length also differed greatly by product, which means that there might be a great difference in wear comfort. Fourth, in terms of the patterns of men's drawers panties, there was difference in side seams, center back seam and front-center patterns. Among a total of 7 products, only one product had side seams, and center back seams were found in two products only. Fifth, in terms of front-center patterns, the drawer panties can be divided into three types, creating three-dimensional effect not to give any pressure on the crotch: i) the cutting line only at the bottom of the front center part where the penis is rested, ii) puff created at the front center by adding a transverse line to the center line, iii) cutting transverse line to separate the penis from the testicles.

The fallowing are the results of the experimental studies of Cordyceps militaris (CM) on the penile nitric oxide synthase (NOS) activity and the level of blood testosterone in hydrocortisone acetate-treated rats. CM was tested for the effects on activity of xanthine oxidase and lipid peroxidation in penis of hydrocortisone acetate-treated rats. In vitro, CM didn't effect the levels of lipid peroxide and the activity of NOS. In the penis of hydrocortisone acetate-treated rats, lipid peroxide, the activities and ratio of type conversion of xanthine oxidase were increased but activity of NOS and content of nitrite were decreased. In vivo, after administration of CM to hydrocortisone acetate-treated rats, levels of lipid peroxide in penis was decreased. Also, the activities and ratio of type conversion of xanthine oxidase were decreased, too. The body weight and concentration of testosterone in the blood were increased. The effects of Cordyceps militalis Broth did better than the effects of Cordyceps militalls Mycelia, These results suggest that CM decrease the activities of free radical generating enzymes such as xanthine oxidase which form lipid peroxide and increase the penile NOS activity and the level of blood testosterone in hydrocortisone acetate-treated rats. Conclusively, CM is capable of improving of sexual ability in hydrocortisone acetate-treated rats.

This paper was performed to investigate the propensity of the diameter of maximum distended urethra from urethra to os penis in mature male dogs of 25 male dogs of different breeds. The measured sites of urethras were divided into 7 regions, i.e. prostate, membrane, isthmus, perineum, scrotum, prescrotum and os penis. By using the inflated balloon catheter filled with contrast medium, the maximum diameter of the distended urethras of each region was recorded and compared among regions. The mean diameter of the lumen from the prostatic urethra to the os penis urethra was gradually narrowed except for the isthmus portion, with a sense of resistance for retraction being noted at the level of ischiatic arch in 22 dogs. Proposed results from this should be utilized as a predictor of a treatment plan for the removal of urethroliths using an urohydropropulsion.

This study was carried out to characterize nonadrenergic, noncholinergic(NANC) relaxation of porcine retractor penis(PRP) muscle induced by electrical field stimulation(EFS) and to investigate the actions of niric oxide(NO) and vasoactive intestinal polypeptide(VIP) as candidates for NANC neurotransmitters. Biphasic relaxations of PRP muscle were induced by EFS to NANC nerve. Rapid-phase relaxation was observed at low frequency(0.5-16Hz) and slow-phase relaxation followed during high frequency(8-60Hz). Both relaxations were frequency-dependent and TTX($1{\times}10^{-6}M$)-sensitive. L-NAME($2{\times}10^{-5}M$) inhibited the rapid-phase relaxation, but not the slow-phase relaxation. The inhibition of the rapid-phase relaxation with L-NAME was reversed by L-arginine ($1{\times}10^{-3}M$) but not by D-arginine($1{\times}10^{-3}M$). Methylene blue($4{\times}10^{-5}M$) reduced the rapid-phase relaxation. Exogenous No(ExoNO, $1{\times}10^{-5}-1{\times}10^{-4}M$) induced dose-dependent relaxations of PRP muscle. Oxyhemoglobin($5{\times}1^{-5}M$) blocked the relaxation induced by ExoNO and inhibited EFS-induced relaxation. Hydroquinone($1{\times}10^{-4}M$) also abolished the relaxation induced by ExoNO, but did not affect EFS-induced relaxation. L-NAME resistant slow-phase relaxation to EFS was inhibited by ${\alpha}$-chymotrypsin(2.5 U/ml). Both methylene blue($4{\times}10^{-5}M$) and Nethylmaleimide($1{\times}10^{-4}M$) reduced the slow-phase relaxation by EFS. [4-Cl-D-$Phe^6$, $Leu^{17}$]-VIP($3{\times}10^{-6}M$) inhibited the slow-phase relaxation by EFS. External applications of VIP ($1{\times}10^{-7}M$) caused relaxations that were simillar to the L-NAME resistant slow-phase relaxations induced by EFS, and relaxant effects of exogenous VIP were blocked by ${\alpha}$-chymotrypsin(2.5 U/ml).
