Primary leiomyosarcoma of the testis.

We report a case of primary leiomyosarcoma of the testis, which was believed to originate from normal testicular structures containing smooth muscle cells, such as blood vessels and contractile cells of the seminiferous tubules. No evidence of tumor spread was found. Treatment consisted of orchiectomy with high ligation of the spermatic cord. The patient received no adjuvant therapy. There was no evidence of tumor after 2 years. The literature is reviewed and the therapeutic approach is discussed.

Correction of penile curvatures caused by unsuccessful hypospadias repair using the scrotal septum pedicled skin tube principle combined with corporoplasty and a modified meatoglanuloplasty.

Scrotal septum pedicled skin tube urethroplasty combined with a modified meatoglanuloplasty and corporoplsty were used in 2 adults. They had three previous hypospadias repair attempts in their childhood, leaving them with a meatus near the glans but with severe ventral penile curvature. Scrotal septum pedicled skin flaps used for the repair, by providing natural vascularization and offering more flexibility, allow the surgeon to reconstruct long urethral defects. The cosmetic and functional results of this combined technique are satisfactory. This principle can also be applied in adult hypospadias cases with deficient preputium in which the midanterior scrotum contains a shiny non-hair-bearing skin.

Acquired ventral penile curvature: spongiofibrosis caused by urethral manipulation.

Fibrosis of the corpus spongiosum, caused by urethral manipulation, and the resulting ventral penile curvatures are known as the urethral manipulation syndrome. This acquired, largely iatrogenic deformity is noticed only be sexually active patients. Partial, gradual disappearance of glans engorgement and irregularities palpable along the penile urethra associated with ventral curvature are constant findings. The post-manipulative ventral curvature can be transient, disappearing when the inflammatory process subsides or the repeated urethral manipulation ceases. Since fibrosis of the corpus spongiosum begins with urethral inflammation, patients in whom irregularities of the penile urethra are observed during urethrography should be questioned about any erectile deformity. Surgical treatment is indicated when the deformity interferes with sexual intercourse or is accompanied by severe urethral strictures.

An entirely endoscopic treatment for simple ureteroceles in nonduplicated systems: a preliminary report.

A case is reported of a large ureterocele associated with a single collecting system. The ureterocele caused frequent urinary retention and it was treated successfully by a staged endoscopic procedure, consisting of complete transurethral resection of the ureterocele followed by perimeatal polytetrafluoroethylene (Teflon) paste injections to prevent subsequent vesicoureteral reflux. This new approach of a combination of 2 endoscopic techniques proved to be useful in this case.

A new, one-stage pedicled scrotal skin graft urethroplasty.

A new 1-stage procedure with a pedicled scrotal flap for bulbomembranous urethral reconstruction is described. The scrotal septum used as a pedicle provides good mobility to the flap. Because of this mobility the method appears to be applicable for reconstruction anywhere along the urethra.

Retroperitoneal fibrosis in association with urothelial tumor.

One of the less common associations of retroperitoneal fibrosis is malignancy. Although there have been many reports on tumors associated with retroperitoneal fibrosis urothelial tumors are rare. We report a case of retroperitoneal fibrosis and urothelial malignancy of the renal pelvis.

Our experience with penile deformations: incidence, operative techniques, and results.

Between the initiation of the "Penile Deformity Clinic" in 1988 in our Department of Urology, and the end of 1992, 1,862 males aged 0 (less than 24 hours old) to 78 years old were examined. Five hundred of them were newborns, aged 0 to 5 days; they were examined to determine the incidence of congenital penile curvature. Two hundred and seventeen congenital curvatures were seen, and 102 of them were corrected surgically using four different corporoplasty techniques. From the 116 Peyronie's Disease patients, 37 were treated surgically, either by corporoplasty or prosthesis implantation. From the 29 iatrogenic penile deformities, all the result of previous hypospadias repairs or urethroplasties for stricture repairs, 18 needed surgical intervention, mostly for cosmetic reasons. Three congenital curvatures, corrected by plication, and one by Nesbit corporoplasty, recurred. Three other cases corrected by Nesbit corporoplasty reported temporary loss of glans sensation, and in a fourth one the sensory loss was permanent. It is our opinion that concentrating the care of these deformities in the hands of a small group of surgeons specialized in penile reconstructive surgery yields the best functional and esthetic results.
