Penis kuda adalah alat kopulasi utama pada kuda. Penelitian ini bertujuan untuk mengetahui gambaran histologi danhistomorfometri penis pada kuda gayo. Sampel penelitian menggunakan penis dari 3 ekor kuda gayo jantan berumur 5-10 tahun yang dipotong di Rumah Potong Hewan Dolok Sanggul, Humbang Hasundutan, Sumatera Utara. Prosesmikroteknik dilakukan terhadap sampel menggunakan pewarnaan hematoksilin-eosin (HE). Pengamatan strukturhistologi menggunakan mikroskop dan dilakukan pengukuran ketebalan lapisan epitel uretra, ketebalan tunikaalbugenia di corpora cavernosa dan corpus spongiosum radix, corpus, dan glans penis menggunakan program aplikasitoupview. Hasilnya dibahas secara deskriptif. Hasil penelitian menunjukkan gambaran histologi penis kuda gayo terdiriatas dua jaringan erektil yaitu corpora cavernosa dan corpus spongiosum serta satu uretra. Sinusoid cavernosal daricorpus cavernosum mengandung banyak trabekula yang terdiri atas jaringan ikat fibroelastis, serat otot polos danfibroblas. Corpus spongiosum memiliki trabekula yang lebih tipis dengan ruang kavernosa yang lebih besar. Corpuscavernosum dan corpus spongiosum ditutup oleh tunika albuginea. Uretra terdiri atas berbagai epitel, seperti epitelberlapis transisional, epitel kolumnar berlapis dan epitel skuamosa. Pengukuran histomorfometri menunjukkan bahwaketebalan tunika albugenia radix dan corpus penis kuda gayo berturut-turut adalah 2.181,10 ± 48,50 µm, dan 2.366,51 ±131,48 µm., sedangkan ketebalan lapisan epitel uretra adalah 50,02 ± 6,95 µm. Kesimpulannya adalah penis kuda gayoterdiri atas radix, corpus dan glans penis. Radix dan corpus penis kuda gayo terdiri atas jaringan ikat, otot polos dansinusoid cavernosal; glans penis terdapat sinus uretra.

Congenital Megalourethra

Abstract Megalourethra is a diffuse dilatation of the anterior urethra due to lack of corpus spongiosum with or without corpora cavernosa; it usually presents as a dilatation of that part of the urethra. The absence of these structures causes a ballooning of the urethra despite there being no mechanical obstruction. A 7-year-old boy presented with the complaints of weak stream, ballooning of the penis before and during voiding urine and post voiding dribbling. After examination and micturating urethrogram, he was diagnosed as having megalourethra, which was then corrected using reduction urethroplasty. These days megalourethra is diagnosed with prenatal ultrasonogram. This was a case of isolated delayed presentation of megalourethra without any associated anomaly.

Corpora Cavernosa

Hypospadias results in various degrees of deficiency of the urethra, corpus spongiosum, and corpora cavernosa. The fibrous tissue that causes ventral curvature replaces Buck fascia and dartos fascia. The skin on the ventral surface may be thin; the prepuce is deficient ventrally and forms a dorsal hood over the glans. As a rule, the location of the meatus does not cause significant obstructive urinary symptoms, although ventral deflection of the stream of urine commonly occurs. When the meatus is more proximal, the stream flows straight downward or backward, requiring the patients to urinate ad modum feminarum. Uncorrected, the curvature of the penis is likely to cause painful erections and result in severe psychologic consequences. INCIDENCE/GENETICS The incidence of hypospadias is about 1 in every 300 male children. If minor degrees of hypospadias are included, this incidence may be as high as 1 in 125 male births. If 1 848 500 male births occur in the United States, we should see 6200 hypospadias cases each year. The risk of occurrence in an infant is 8% if his father has hypospadias and 14% if a sibling has the condition; if two members of the same family have hypospadias, the risk is about 21%. The cause of hypospadias is still unknown.

Mr. Bauer has discovered, by the aid of the microscope, that the human urethra is made up of two parts, an internal membrane and an external muscular covering; the former, very thin and destitute of fibres, is thrown into folds in a collapsed state, and upon its surface are numerous orifices of glands; the latter is made up of short interwoven fibres, forming fasciculi united by an elastic substance of the consistence of mucus: these observations show the fallacy of the common opinion, that the lining of the urethra consists of circular contractile fibres, and throw a new light upon the disease called Stricture; a spasmodic stricture being a contraction of a small portion of the longitudinal muscular fibres, while the others are relaxed; and a permanent stricture consisting in the exudation of coagulable lymph, in consequence of inflammation, between the fasciculi of muscular fibres and upon the internal membrane. After adverting to what is known respecting the structure of the corpus spongiosum, and corpora cavernosa, the author proceeds to state the result of Mr. Bauer’s examination of those parts. The cellular structure of the corpora cavernosa is made up of many thin membranous plates, very elastic, and so connected as to form a trellis-work, the edge of which is attached to the elastic ligamentous substance which surrounds them, and which forms the septum that separates them. The structure of the corpus spongiosum resembles that of the corpora cavernosa, except that the parts are formed upon a smaller scale, and that there are no muscular fibres in its ligamentous elastic covering. The various details and descriptions in this paper are illustrated by Mr. Bauer’s drawings.
