In our study, the elastic fibers of the corpora cavernosa and corpus spongiosum of the rats from the TS group did not exhibit significant differences in the volume density, compared with those of the rats from other groups, thereby indicating unaltered organ elasticity.
Additionally, gradual instillation of 10 cc of anesthetic jelly during catheterization of an injured urethra may prevent leakage of jelly into the corpus spongiosum. However, in an uninjured urethra, slow instillation of 20 cc anesthetic jelly might help the clinician in more difficult cases.
(10) The surrounding anatomic structures vary by location within the urethra but include the subepithelial connective tissue, corpus spongiosum, corpus cavernosum, prostate, periurethral muscle, extraprostatic soft tissue, anterior vagina, bladder neck, or other adjacent organs.
However, under particular circumstances as was in the present case, being more aggressive may be useful because there may be parts of corpus spongiosum and urethra affected by the infection.
Intraoperative findings showed more extensive necrosis than expected from the gangrene of the skin, with ischemic changes reaching deep into the perineal area of the corpus spongiosum. Literature review showed that elective gangrene of the corpus spongiosum is very rare and in our case no etiology could be found.
DISCUSSION: Male anterior urethra is the part of the urethra spanning from the bulbo-membranous junction to the external urethral meatus coursing through the corpus spongiosum. By virtue of its anatomical location and use, it is exposed to different types of pathologies.
It seems plausible to conclude that the patient was born with congenital defect of hypoplasia of corpus spongiosum, according to the medical history of the transparent part of the skin at birth and the outcome of the spontaneous urethral fistula when he was 2 years old.
GRADE II Injury to skin and constriction of corpus spongiosum but no evidence of urethral injury.
Strict adherence between connecting tubes and corpus spongiosum of urethra may have facilitated the occurrence of the lesion.
After minimal debridement and mobilization of proximal and distal corpus spongiosum, the urethra was spatulated.
Immediate exploration with repair of the corporal tear is the standard and should be done in the presence of a typical history and supportive physical signs.[sup.6] One must avoid contact between the severed corpus spongiosum and corporal tissue to obviate the risk of postoperative impotence as a consequence of spongio-cavernosal fistula.
