Effects of modified penoplasty for concealed penis in children.

PURPOSE: To evaluate the effect of modified penoplasty in the management of concealed penis. METHODS: We retrospectively reviewed 96 consecutive patients with concealed penis, which had been surgically corrected between July 2013 and July 2015. All patients underwent modified Shiraki phalloplasty. All patients were scheduled for regular follow-up at 1, 3, and 6 months after the surgery. Data on the patients' age, operative time, postoperative complications, and parents' satisfaction grade were collected and analyzed. RESULTS: The mean follow-up period was 17.4 months (range 7-31 months). The mean operative time was 63.2 ± 8.7 min. The mean perpendicular penile length was 1.89 ± 0.77 cm preoperatively and 4.42 ± 0.87 cm postoperatively, with an improved mean length of 2.5 ± 0.68 cm in the flaccid state postoperatively (p < 0.05). The patients' satisfaction grades after the surgery were improved significantly (p < 0.05). Fifty-two patients had penile lymphedema postoperatively; however, it disappeared spontaneously within 3 months. Additionally, postoperative wound infection occurred in two patients. There were no complications such as flap necrosis, penile shaft contracture, voiding difficulty, and erection difficulties. CONCLUSION: The modified Shiraki phalloplasty for concealed penis can achieve maximum utilization of prepuce to assure coverage of the exposed penile shaft. It has fewer complications, achieving marked asthetics, and functional improvement. It is a relatively ideal means for treating concealed penis.

Congenital phimosis in patients with and without lichen sclerosus: distinct expression patterns of tissue remodeling associated genes.

PURPOSE: Lichen sclerosus is a potentially important factor in the ongoing debate concerning the pathology of persistent congenital phimosis. We assessed the molecular differences of congenital phimosis in boys with and without lichen sclerosus compared to age matched boys with fully retractable foreskins to gain more insight into the pathogenesis of fibrotic remodeling of the prepuce. MATERIALS AND METHODS: A total of 150 boys were circumcised in a prospective study between 2007 and 2009. Using target gene specific preamplification and quantitative real-time polymerase chain reaction based low density arrays, we measured the mRNA expression of 45 tissue remodeling associated genes in foreskins of boys with absolute phimosis and lichen sclerosus (8 patients) and those of an age matched group of boys with phimosis but no lichen sclerosus (8), as well as a control group with foreskins without delimitable changes (6). Complementary protein expression and inflammatory infiltrates were assessed by immunohistochemical analysis. RESULTS: Cellular composition, inflammatory infiltrate and microenvironment as seen in histologically proven lichen sclerosis differed significantly from the other groups. In particular, lichen sclerosis was characterized by over expression of bone morphogenetic protein 2 and its corresponding receptor, matrix metalloproteinases 1 and 9 and tissue inhibitor of metalloproteinases 1, cytokine chemokine ligands 5 (RANTES) and interleukin 4, and transforming growth factor-ß2 and its corresponding receptor. There were no major molecular differences between specimens from boys with congenital phimosis without signs of lichen sclerosis and controls. CONCLUSIONS: Distinct expression patterns of tissue remodeling associated genes are evident in boys with congenital phimosis and lichen sclerosis, while congenital phimosis without lichen sclerosis represents a physiological condition.

Phimosis in cats: 10 cases (2000-2008).

Medical records of 10 cats diagnosed with phimosis were reviewed. The most common clinical signs exhibited were stranguria and pollakiuria, which occurred in eight out of 10 cats. The diagnosis of phimosis was made from physical examination alone in all cats. Eight of the 10 cats had surgical widening of the preputial orifice. Seven of these eight cats had follow-up of > or = 1 month, consisting of communications with the owner or referring veterinarian, who revealed resolution of preoperative clinical signs that were attributed to phimosis.

Fímosis: revisión bibliográfica: 2008 / Phimosis: bibliographic revision 2008

La fimosis (del griego phimos) es una condición de los anexos cutáneos del pene que altera la mecánica de este órgano. La fimosis se debe a la estenosis del orificio prepucial que impide la retracción completa del prepucio para dejar el glande descubierto, activamente durante la flacidez del pene, o pasivamente durante la erección. O aún más simple, la fimosis es la estrechez del prepucio, vale decir, el glande no se puede descubrir. Lo normal es que el glande pueda descubrirse para poder asearlo en estado flácido y para tener relaciones sexuales placenteras. El prepucio se desarrolla como una pequeña capa de epitelio que rodea el glande, a partir de la duodécima semana de gestación. Para el momento del nacimiento, oculta completamente al glande y está adherido fuertemente a su epitelio. En el transcurso de los primeros cuatro a cinco años de edad, se produce la separación gradual del prepucio, mediante las erecciones intermitentes y la acumulación de células de descamación, las cuales no deben ser confundidas como esmegma. Si no se puede retraer completamente el prepucio hasta detrás del glande, entonces habría fimosis. No todos los prepucios se retraen automáticamente al experimentar una erección del pene. Si se puede hacer manualmente, no se tiene fimosis(AU)

Lichen sclerosus et atrophicus in pediatric and adult male patients with congenital and acquired phimosis.

Lichen sclerosus et atrophicus is a chronic inflammatory sclerotic and atrophic disease of unknown cause that predominantly affects male and female genital skin. This study was designed to evaluate histological characteristics of congenital and acquired phimoses among pediatric (n=60) and adult (n=60) male patients who were admitted for circumcision to the Clinics of Urology and Pediatric Surgery of Kaunas University of Medicine Hospital between 2000 and 2003 and to determine the rate of lichen sclerosus et atrophicus and other histological diagnoses among them. This study demonstrates that 45.1% of congenital and 62.3% of acquired phimoses show histological signs of lichen sclerosus et atrophicus. The rate of lichen sclerosus et atrophicus was statistically significantly higher among patients with acquired than congenital phimosis. Boys with acquired narrowing of prepuce were statistically significantly 3.9 times more likely to develop lichen sclerosus et atrophicus than those with congenital phimosis. There were no statistically significant differences between rates of lichen sclerosus et atrophicus and other dermatological diagnoses among pediatric and adult male patients if the type of phimosis (acquired or congenital) was considered. Histological features of lichen sclerosus et atrophicus and other histological diagnoses in boys and men with phimosis were detected with equal frequency irrespective the age of the subjects. The rate of lichen sclerosus et atrophicus was similar among all boys (56.7%) and men (53.3%) treated for phimosis. Only the type of phimosis had a statistically significant influence on the rate of lichen sclerosus et atrophicus and other histological diagnoses.

[Phimosis: medical treatment or circumcision?]. / Décalottage ou circoncision: quelle indication dans le phimosis?

Phimosis remains a major question for mothers and induces a high number of consultations. However, large epidemiologic series have shown that congenital phimosis may disappear spontaneously in around 80% of cases with development and should'nt need any treatment before the age of five or six years old. Theses elements go against sociocultural habits which induce many circumcisions before the age of six. Corticoid treatment of phimosis seems to be very efficient to facilitate the disparition of phimosis. The aim of this literature review is to evaluate medical, socioeconomical and therapeutics aspects of phimosis. Based on these data, we recommend never to treat phimosis before the age of one year old, to wait as long as possible for spontaneous evolution of phimosis until the age of five years old, and, in case of non evolution of congenital phimosis or pathologic phimosis to use as first step treatment corticoid topics rather than surgical treatment.

Congenital phimosis in a cat.

An 8-week-old domestic shorthair cat was presented with a history of pollakiuria and polydipsia. No abnormalities were detected during the clinical examination other than the penis could not be extruded from the prepuce. Urine culture demonstrated a growth of E. coli, which was treated with a prolonged course of amoxycillin. The polydipsia resolved and the pollakiuria improved but did not completely abate after antibiotic treatment and the cat had occasional bouts of haematuria. Because of the history of pollakiuria and polydipsia and the ongoing, occasional bouts of haematuria, the cat underwent surgical correction of the congenital phimosis. A small wedge of the dorsal prepuce was removed and the ipsilateral edges of the prepuce were apposed using a simple interrupted pattern. The procedure was quick, easy to perform and led to a resolution of the occasional bouts of haematuria and pollakiuria.

Secondary congenital megaprepuce.

We report a case of a 3-month-old boy with a megaprepuce presented since birth. Certain aspects of the aetiology, denomination, diagnosis and treatment are discussed. We compare our case with the three unique cases published in the literature.
