Prognosis for balanoposthitis is fair to good with prompt treatment. The development of hematomas, phimosis & paraphimosis is a potential complication.

Paraphimosis

Paraphimosis is the inability to completely

the penis into the prepuce.

Paraphimosis may be caused by edema of the prepuce, the administration of certain , congestion of the penis, neurogenic paralysis of the penis or space occupying lesions such as on the prepuce or penis. Edema, congestion and space occupying lesions cause the penis to be too large to completely retract into the preputal fold. Tranquilizers and neurogenic atrophy inhibit the muscular control of the penis, preventing the retraction of the penis into the prepuce.

Predisposition includes recent castration.

The clinical presentation of paraphimosis includes pain on palpation of the penis, ulceration of the penile epithelium, and that all or part of the penis remains visible outside of the prepuce. This can allow the penile tissues to dry out and predispose the penis to damage while exposed.

Diagnosis can be made through case history of tranquilizers and clinical signs and symptoms.

Treatment includes the administration of rest, NSAID’s, cold hydrotherapy to the penis and prepuce and the lubrication and manual replacement of the penis inside the prepuce with a support band. Once the penis is retracted a can be placed in the urethral orifice to prevent the penis from extruding. Surgical removal of space occupying lesions may be necessary in some cases. Antidotes can be administered for tranquilizers. Prognosis for paraphimosis is good if treatment is prompt. If treatment is delayed prognosis is guarded as ischemia and secondary bacterial infection of the penis may lead to , which requires amputation of the penis to prevent septicemia.

Phimosis

Phimosis is the inability to

the penis through the preputal orifice.

Phimosis can be caused by congenital malformation of the prepuce, edema of the prepuce, the presence of space occupying lesions on the prepuce or the penis, adhesions or fibrosis of the preputal fold, neurogenic paralysis or the excessive buildup of smegma or other debris in the prepuce.
